Carbon dioxide is 53% more dense than dry air, but is long lived and thoroughly mixes in the atmosphere. Properties of Carbon Dioxide. The reaction between hydrochloric acid and calcium carbonate (limestone or chalk) is shown below: The carbonic acid (H2CO3) then decomposes to water and CO2: Such reactions are accompanied by foaming or bubbling, or both, as the gas is released. 4 L. Therefore, 30 gm of NO occupy = 22. It does not store any personal data. 1.96 g/L B. below the table is an image version for offline viewing Although, this may be due to atmospheric reactions occurring at the puddle site. CO2 is an asphyxiant gas and not classified as toxic or harmful in accordance with Globally Harmonized System of Classification and Labelling of Chemicals standards of United Nations Economic Commission for Europe by using the OECD Guidelines for the Testing of Chemicals. Carbon dioxide is also used to create a hypoxic environment for carbonic maceration, the process used to produce Beaujolais wine. [135], Carbon dioxide was first liquefied (at elevated pressures) in 1823 by Humphry Davy and Michael Faraday. Carbon dioxide is one of the mediators of local autoregulation of blood supply. Or, one can calculate this from this website. Carbon dioxide exerts a larger overall warming influence than all of the other greenhouse gases combined. The canary is more sensitive to asphyxiant gases than humans, and as it became unconscious would stop singing and fall off its perch. Carbon dioxide is also used in several related cleaning and surface-preparation techniques. It is found in the gas state at room temperature. 3. 46.0 g/l 22.0 g/l 5.09 10-1 g/l 1.96 g/l? Thus if the outdoor concentration is 400ppm, indoor concentrations may reach 2,500ppm with ventilation rates that meet this industry consensus standard. Properties of Carbon dioxide. Density and specific weight of carbon dioxide at given temperatures and pressures: For full table with Density and Specific Weight - rotate the screen! Specific weight is given as N/m3 and lbf/ ft3. The mass of the ideal gas can be calculated using its molecular weight: density = molar mass/molar volume. lower limit for calculation: -55 C, 5,4 bar bar upper limit: 30 C, 72,14 bar. Assume ideal conditions.PV=nRTn=m/M (n=moles ; m=mass ; M=molar mass)PV=(m/M)RTPV=mRT/MMPV=mRTMP. We don't collect information from our users. 5.6X It is slightly toxic.

National Center for Biotechnology Information. Its environmental advantages (GWP of 1, non-ozone depleting, non-toxic, non-flammable) could make it the future working fluid to replace current HFCs in cars, supermarkets, and heat pump water heaters, among others. This is usually the opposite of the desired effect when welding, as it tends to embrittle the site, but may not be a problem for general mild steel welding, where ultimate ductility is not a major concern. Carbon dioxide and methane sorption in high volatile bituminous coals from . Carbon dioxide is a colorless gas with a density about 53% higher than that of dry air. The calculator below can be used to estimate the density and specific weight of gaseous carbon dioxide at given temperature and pressure. Thus, #"CO"_2# is fairly ideal. 1.98 g/L - gas: [38] This may have knock-on effects on other parts of ecosystems as herbivores will need to eat more food to gain the same amount of protein. CO2 might enjoy a renaissance because one of the main substitutes to CFCs, 1,1,1,2-tetrafluoroethane (R134a, a hydrofluorocarbon (HFC) compound) contributes to climate change more than CO2 does. 4 What is the volume occupied by 22 g of CO2 at STP? Heat content data, heat of vaporization, and entropy values are relative to the liquid state at 0 C temperature and 3483 kPa pressure. The values of standard temperature and pressure are 273 Kelvin and one atmosphere, respectively. This carries the risk that unconsciousness may result before the need to breathe becomes overwhelming, which is why hyperventilation is particularly dangerous before free diving.[71]. Increases in atmospheric concentrations of CO2 and other long-lived greenhouse gases such as methane, nitrous oxide and ozone increase the absorption and emission of infrared radiation by the atmosphere, causing the observed rise in average global temperature and ocean acidification. They have widespread uses in industry because they can be used to neutralize waste acid streams. [98] One of the most important repercussions of increasing ocean acidity relates to the production of shells out of calcium carbonate (CaCO3). Carbon dioxide in the form of dry ice is often used during the cold soak phase in winemaking to cool clusters of grapes quickly after picking to help prevent spontaneous fermentation by wild yeast. The taste of soda water (and related taste sensations in other carbonated beverages) is an effect of the dissolved carbon dioxide rather than the bursting bubbles of the gas. Gasoline engines produce 2.3 kg of CO2 per litre of gasoline consumed. Carbon dioxide is a by-product of the fermentation of sugar in the brewing of beer, whisky and other alcoholic beverages and in the production of bioethanol. As an example, the chemical reaction between methane and oxygen: Iron is reduced from its oxides with coke in a blast furnace, producing pig iron and carbon dioxide:[99], Carbon dioxide is a byproduct of the industrial production of hydrogen by steam reforming and the water gas shift reaction in ammonia production. In the case of bottled and kegged beer, the most common method used is carbonation with recycled carbon dioxide. As the source of available carbon in the carbon cycle, atmospheric CO2 is the primary carbon source for life on Earth. The symmetric stretching mode does not create an electric dipole so is not observed in IR spectroscopy, but it is detected in by Raman spectroscopy at 1388cm1 (wavelength 7.2 m).[20]. The Density of Carbon Dioxide @ STP = 0.1234 lb/cu ft. molecules in the gas phase are ever exactly linear. The density of carbon dioxide at STP is 1.964 grams per liter (g/L). Only emails and answers are saved in our archive. [96] Regardless of the type of organic material, the production of gases follows well defined kinetic pattern. Temperature and Pressure, Thermophysical properties at standard conditions, 1 lb/gal(UK) = 0.8327 lb/gal(US liq) = 16 oz/gal(UK) = 13.323 oz/gal(US liq) = 168.179 lb/yd, 1 lb/gal(US liq) = 1.2009 lb/gal(UK) = 19.215 oz/gal(UK) = 16 oz/gal(US liq) = 201.97 lb/yd, 1 oz/gal(UK) = 0.8327 oz/gal(US liq) = 6.2360 kg/m, 1 oz/gal(US liq) = 1.2009 oz/gal(UK) = 7.4892 kg/m. Since #Z < 1#, #"CO"_2# is easier to compress than a comparable ideal gas (thus its molar volume is less than #22.711# at #"1 bar"# and #"273.15 K"#). [132]:22. [24] Only very strong nucleophiles, like the carbanions provided by Grignard reagents and organolithium compounds react with CO2 to give carboxylates: In metal carbon dioxide complexes, CO2 serves as a ligand, which can facilitate the conversion of CO2 to other chemicals.[25]. It is a non-flammable gas. The result of this experiment, and the conclusion of theoretical calculations[22] based on an ab initio potential energy surface of the molecule, is that none of the It is produced by thermal decomposition of limestone, CaCO3 by heating (calcining) at about 850C (1,560F), in the manufacture of quicklime (calcium oxide, CaO), a compound that has many industrial uses: Acids liberate CO2 from most metal carbonates. The standard SI unit is kilograms per cubic meter ( kg/m3 ). A vessel contains methane (CH 4), ethane . Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! One mole of an ideal gas at standard temperature and pressure has the volume 22.4 liters. High concentrations of carbon dioxide can also be used to kill pests. Children have been killed in the same way near the city of Goma by CO2 emissions from the nearby volcano Mount Nyiragongo.

It is relatively nontoxic and noncombustible, but it is heavier than air and may asphyxiate by the displacement of air. Carbon Dioxide. [132]:5,31 Percentages of CO2 vary for different species, based on identified optimal percentages to minimize distress. What is the density of carbon dioxide at STP 2.0 g or L? Carbon dioxide differential above outdoor concentrations at steady state conditions (when the occupancy and ventilation system operation are sufficiently long that CO2 concentration has stabilized) are sometimes used to estimate ventilation rates per person. [92] This process is called calcification and is important to the biology and survival of a wide range of marine organisms. However, you may visit "Cookie Settings" to provide a controlled consent.

This discovery confirmed the theory that carbon dioxide could exist in a glass state similar to other members of its elemental family, like silicon dioxide (silica glass) and germanium dioxide. A candy called Pop Rocks is pressurized with carbon dioxide gas[111] at about 4,000kPa (40bar; 580psi). The calculator below can be used to estimate the density and specific weight of gaseous carbon dioxide at given temperature and pressure.The output density is given as kg/m3, lb/ft3, lb/gal(US liq) and sl/ft3. There are two standards, commonly used in schools: STP (standard temperature and pressure) which is 0 C and 1 atmosphere. Liquid carbon dioxide forms only at pressures above 0.51795(10)MPa[2] (5.11177(99)atm); the triple point of carbon dioxide is 216.592(3)K[2] (56.558(3)C) at 0.51795(10)MPa[2] (5.11177(99)atm) (see phase diagram). One mole of an ideal gas at standard temperature and pressure has the volume 22.4 liters. This cookie is set by GDPR Cookie Consent plugin. The length of the carbon-oxygen bond in carbon dioxide is 116.3pm, noticeably shorter than the roughly 140-pm length of a typical single CO bond, and shorter than most other CO multiply-bonded functional groups such as carbonyls. [52] However a review of the literature found that most studies on the phenomenon of carbon dioxide induced cognitive impairment to have a small effect on high-level decision making and most of the studies were confounded by inadequate study designs, environmental comfort, uncertainties in exposure doses and differing cognitive assessments used. [76] It has an atmospheric lifetime that increases with the cumulative amount of fossil carbon extracted and burned, due to the imbalance that this activity has imposed on Earth's fast carbon cycle. [105][106] At very high concentrations (100 times atmospheric concentration, or greater), carbon dioxide can be toxic to animal life, so raising the concentration to 10,000ppm (1%) or higher for several hours will eliminate pests such as whiteflies and spider mites in a greenhouse.[107]. Such an experiment[21] has been performed for carbon dioxide. [121] It acts as both a pressurizing agent and, when dissolved into the underground crude oil, significantly reduces its viscosity, and changing surface chemistry enabling the oil to flow more rapidly through the reservoir to the removal well. The ideal gas equation is:PV = nRTor Density () = RTPM Molar mass (M) of CO2 is 44.01 g/mol.At STP, P = 1 atm and T . Carbon dioxide is also introduced into the oceans through hydrothermal vents. The cookie is used to store the user consent for the cookies in the category "Other. This approach can increase original oil recovery by reducing residual oil saturation by 723% additional to primary extraction. [63] High concentrations of CO2 produced by disturbance of deep lake water saturated with CO2 are thought to have caused 37 fatalities at Lake Monoun, Cameroon in 1984 and 1700 casualties at Lake Nyos, Cameroon in 1986.[64]. Carbon dioxide can be used as a means of controlling the pH of swimming pools,[131] by continuously adding gas to the water, thus keeping the pH from rising. About half of excess CO2 emissions to the atmosphere are absorbed by land and ocean carbon sinks. [125], Researchers have developed a process called electrolysis, using enzymes isolated from bacteria to power the chemical reactions which convert CO2 into fuels.[126][127][128]. There is about fifty times as much carbon dioxide dissolved in the oceans as exists in the atmosphere. Molecular formula: CO 2: Molar mass: 44.0095(14) g/mol: Density: 1,600 g/L - solid. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. It has a melting point of -55.6C and has a boiling point of -78.5C. Another form of solid carbon dioxide observed at high pressure is an amorphous glass-like solid. Specific weight, , has units typically [N/m3] or [lbf/ft3] is defined by the ratio of the weight to the volume of a substance: where g = acceleration due to gravity, units typically [m/s2] and value on Earth usually given as 9.80665 [m/s2] or 32.17405 [ft/s2]. This also gives a real mass density of #color(blue)("0.001951 g/mL")# at #"1 bar"# and #0^@ "C"#. Contribution of Working Group III to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change, "The Oxford Principles for Net Zero Aligned Carbon Offsetting", "Carbonated (Sparkling) Water: Good or Bad? OR: Temperature: The following thermodynamic properties will be calculated: density, dynamic viscosity, kinematic viscosity, specific enthalpy, specific entropy . The chemical formula as well as molar mass has also been listed. CO2 is a versatile industrial material, used, for example, as an inert gas in welding and fire extinguishers, as a pressurizing gas in air guns and oil recovery, and as a supercritical fluid solvent in decaffeination of coffee and supercritical drying. What is the density of carbon dioxide at STP? The oceans act as an enormous carbon sink, and have taken up about a third of CO2 emitted by human activity.[90]. The hydration equilibrium constant of carbonic acid is, at 25C: Hence, the majority of the carbon dioxide is not converted into carbonic acid, but remains as CO2 molecules, not affecting the pH. [citation needed] When used for MIG welding, CO2 use is sometimes referred to as MAG welding, for Metal Active Gas, as CO2 can react at these high temperatures. If you do the math, you will find that carbon dioxide is 1.383 . [77] Burning fossil fuels is the main cause of these increased CO2 concentrations and also the main cause of climate change. Liquid carbon dioxide (industry nomenclature R744 or R-744) was used as a refrigerant prior to the use[citation needed] of dichlorodifluoromethane (R12, a chlorofluorocarbon (CFC) compound). [62], Local concentrations of carbon dioxide can reach high values near strong sources, especially those that are isolated by surrounding terrain. Though a growing forest will absorb many tons of CO2 each year, a mature forest will produce as much CO2 from respiration and decomposition of dead specimens (e.g., fallen branches) as is used in photosynthesis in growing plants. [79] Light emission from the Earth's surface is most intense in the infrared region between 200 and 2500cm1,[80] as opposed to light emission from the much hotter Sun which is most intense in the visible region. Density, , hasunits typically [kg/m3] or [lb/ft3], and is defined by the ratio of the mass to the volume of a substance: where m = mass, units typically [kg] or [lb] V = volume, units typically [m3] or [ft3]. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. Another medical use are the mofette, dry spas that use carbon dioxide from post-volcanic discharge for therapeutic purposes. The atmospheres of greenhouses may (if of large size, must) be enriched with additional CO2 to sustain and increase the rate of plant growth. The molar mass of sulfur dioxide, SO2 can be calculated and it is given as: 32.07 + (162) = 64.07 grams per mole. Write balanced chemical equation describe photosynthesis . He observed that the fixed air was denser than air and supported neither flame nor animal life. This cookie is set by GDPR Cookie Consent plugin. Water, ethanol, and acetone are all soluble in it. Therefore @ STP (60F and 1 atmosphere) CO2 is 1.53 times heavier than air. Leavening agents cause dough to rise by producing carbon dioxide. Molar volume at STP can be used to convert from moles to gas volume and from gas volume to moles.

Rather, breathing is stimulated by higher carbon dioxide levels. Several studies suggested that 2.0 percent inspired concentrations could be used for closed air spaces (e.g. The equality of 1 mole = 22.4 L is the basis for the conversion factor. At STP, one mole of an ideal gas will . Advertisement Advertisement New questions in Chemistry. The table below gives thermodynamic data of liquid CO 2 in equilibrium with its vapor at various temperatures. In very alkaline water (pH > 10.4), the predominant (>50%) form is carbonate. [82] This means that some fraction (a projected 20-35%) of the fossil carbon transferred thus far will persist in the atmosphere as elevated CO2 levels for many thousands of years after these carbon transfer activities begin to subside. Densities, molecular weight and chemical formulas of some common gases can be found in the table below: 1)NTP - Normal Temperature and Pressure- is defined as 20oC (293.15 K, 68oF)and 1 atm ( 101.325 kN/m2, 101.325 kPa, 14.7 psia, 0 psig, 30 in Hg, 760 torr) The reduction of CO2 to CO is ordinarily a difficult and slow reaction: Photoautotrophs (i.e. What is the molar volume of carbon dioxide? Thus: #= (("1 bar")("44.009 g/mol"))/(("0.083145 L"cdot"bar/mol"cdot"K")("273.15 K"))#. #= (("1 bar")("44.009 g/mol"))/(("0.083145 L"cdot"bar/mol"cdot"K")("273.15 K")(0.9934))#, Oh look at that it's dead-on, and all I did was use #Z# as a correctional factor in the ideal gas law. At temperatures and pressures above the critical point, carbon dioxide behaves as a supercritical fluid known as supercritical carbon dioxide. Here is a general strategy for getting a quick and dirty estimate of gas densities: Find the molar volume. What is. [59][60] ASHRAE Standard 62.12007 ventilation rates may result in indoor concentrations up to 2,100ppm above ambient outdoor conditions. His interpretation was that the rest of the charcoal had been transmuted into an invisible substance he termed a "gas" or "wild spirit" (spiritus sylvestris). The body produces approximately 2.3 pounds (1.0kg) of carbon dioxide per day per person,[66] containing 0.63 pounds (290g) of carbon. Before more effective technologies were developed, miners would frequently monitor for dangerous levels of blackdamp and other gases in mine shafts by bringing a caged canary with them as they worked. Mathematical Definition of Density The formal definition of density is mass per unit volume . the fact that the nuclear motion volume element vanishes for linear geometries. Step 1: Given data. [122] In mature oil fields, extensive pipe networks are used to carry the carbon dioxide to the injection points. National Fire Protection Association Code 12. Solid carbon dioxide is always below 78.5C (109.3F) at regular atmospheric pressure, regardless of the air temperature. Further when normal motorcycle conditions were achieved (such as highway or city speeds) or the visor was raised the concentration of CO2 declined to safe levels (0.2%).[57][58]. At high pH, it dissociates significantly into the carbonate ion (CO23): In organisms carbonic acid production is catalysed by the enzyme, carbonic anhydrase. How do stoichiometric ratios relate to molar volume of a gas? To convert heat values to joules per mole values, multiply by 44.095 g/mol. This means that carbon dioxide should be about 44/32 = 1.375 times as heavy as an equivalent volume of oxygen. Concentrations in poorly ventilated spaces can be found even higher than this (range of 3,000 or 4,000ppm). [28] This form of glass, called carbonia, is produced by supercooling heated CO2 at extreme pressures (4048GPa, or about 400,000 atmospheres) in a diamond anvil. This counter-intuitive result is trivially due to National Institutes of Health. Changes in ocean chemistry can have extensive direct and indirect effects on organisms and their habitats. [70], Although the body requires oxygen for metabolism, low oxygen levels normally do not stimulate breathing. STP stands for standard temperature (273 K or 0 C) and pressure (1 atm). The nickel-containing enzyme carbon monoxide dehydrogenase catalyses this process. About Us Become a Tutor Blog. This is so for all molecules (except diatomics!). [49][50] Yet, other studies show a decrease in cognitive function even at much lower levels. Additionally, and crucially to life on earth, photosynthesis by phytoplankton consumes dissolved CO2 in the upper ocean and thereby promotes the absorption of CO2 from the atmosphere. [9][10] Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change. Direct effects of low-to-moderate CO2 concentrations on human decision-making performance", "Associations of Cognitive Function Scores with Carbon Dioxide, Ventilation, and Volatile Organic Compound Exposures in Office Workers: A Controlled Exposure Study of Green and Conventional Office Environments", "Exposure Limits for Carbon Dioxide Gas CO, In-Flight Carbon Dioxide Exposures and Related Symptoms: Associations, Susceptibility and Operational Implications, "Effect of prolonged exposure to 0.5% CO2 on kidney calcification and ultrastructure of lungs", "Ask the doc: Does my helmet make me stupid? Conversely, a rise in the partial pressure of CO2 or a lower pH will cause offloading of oxygen from hemoglobin, which is known as the Bohr effect. [103], In addition to conventional processes using CO2 for chemical production, electrochemical methods are also being explored at a research level.

What is the density of carbon dioxide CO2 at STP? 0.509 g/L C. 2.40 g/L D. 1.00 g/L Answer: A; Difficulty: easy; Reference: 12.8; Learning Objective: 12.8. Calcification involves the precipitation of dissolved ions into solid CaCO3 structures, structures for many marine organisms, such as coccolithophores, foraminifera, crustaceans, mollusks, etc. It is a colourless and odourless gas. Ribulose-1,5-bisphosphate carboxylase oxygenase, commonly abbreviated to RuBisCO, is the enzyme involved in the first major step of carbon fixation, the production of two molecules of 3-phosphoglycerate from CO2 and ribulose bisphosphate, as shown in the diagram at left. In the gas phase, carbon dioxide molecules undergo significant vibrational motions and do not keep a fixed structure. What is the density of carbon dioxide at STP if 1 mole occupies 22.4L? See the answer Show transcribed image text Expert Answer 100% (1 rating) Transcribed image text: Calculate the density of carbon dioxide at STP. Because it is heavier than air, in locations where the gas seeps from the ground (due to sub-surface volcanic or geothermal activity) in relatively high concentrations, without the dispersing effects of wind, it can collect in sheltered/pocketed locations below average ground level, causing animals located therein to be suffocated. Under "standard" conditions of 0 degrees Celsius and 1 atmosphere of pressure, carbon dioxide exhibits a density of 0.001977 g/mL. How do you calculate molar volume of a gas at STP? Plants, algae and cyanobacteria use energy from sunlight to synthesize carbohydrates from carbon dioxide and water in a process called photosynthesis, which produces oxygen as a waste product. The molar mass of carbon dioxide is 44.01 grams. Carbon dioxide induction is commonly used for the euthanasia of laboratory research animals. You can calculate this using the following explanation from antoine.frostburg: At STP, one mole of an ideal gas will occupy 22.414 L. At other temperatures and pressures, the molar volume of an ideal gas is V/n = RT/P. The Physical properties of Carbon are the characteristics that can be observed without changing the substance into another substance. [17] It is a byproduct of fermentation of sugars in bread, beer and wine making, and is added to carbonated beverages like seltzer and beer for effervescence. Miners, who are particularly vulnerable to gas exposure due to insufficient ventilation, referred to mixtures of carbon dioxide and nitrogen as "blackdamp", "choke damp" or "stythe". Carbon dioxide (relative molecular mass 44) is about one and a half times denser than air (average relative molecular mass about 29), and mixing of gases of differing densities by diffusion can be a slow process unless the mixture is deliberately stirred. We can also use the compressibility factor #Z = (PV)/(nRT)#, which is an empirical constant related to how easily #"CO"_2# responds to compression. How many molecules would there be in 56 liters of carbon dioxide at STP? plants and cyanobacteria) use the energy contained in sunlight to photosynthesize simple sugars from CO2 absorbed from the air and water: The redox potential for this reaction near pH7 is about 0.53V versus the standard hydrogen electrode. The Density of Air @ Standard Temperature and Pressure (there are somewhat different definitions of STP unforetunately) is 0.0806 lb/cu ft. [15] These sinks can become saturated and are volatile, as decay and wildfires result in the CO 2 being released back into the atmosphere. use the molar volume of a gas at STP to calculate the density of nitrogen gas at STP. [15] These sinks can become saturated and are volatile, as decay and wildfires result in the CO2 being released back into the atmosphere. At low concentrations the gas is odorless; however, at sufficiently high concentrations, it has a sharp, acidic odor. [17] Carbon dioxide has attracted attention in the pharmaceutical and other chemical processing industries as a less toxic alternative to more traditional solvents such as organochlorides. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. However, because of allosteric effects on the hemoglobin molecule, the binding of CO2 decreases the amount of oxygen that is bound for a given partial pressure of oxygen. - RevZilla", "Three die in dry-ice incident at Moscow pool party", "A Woman Died from Dry Ice Fumes. As a result, breathing low-pressure air or a gas mixture with no oxygen at all (such as pure nitrogen) can lead to loss of consciousness without ever experiencing air hunger. A person's breathing rate influences the level of CO2 in their blood. [67] In humans, the blood carbon dioxide contents is shown in the adjacent table. Carbon dioxide is a food additive used as a propellant and acidity regulator in the food industry. Consequently, it may be obtained directly from natural carbon dioxide springs, where it is produced by the action of acidified water on limestone or dolomite. The measured density of He at STP is 0.1784 g/l. To solve the problem, you have to find the mass of a sample of unit volume. . a submarine) since the adaptation is physiological and reversible, as deterioration in performance or in normal physical activity does not happen at this level of exposure for five days. Refer to (cellular respiration, anaerobic respiration and photosynthesis). It is an intensive property, which is mathematically defined as mass divided by volume: = m/V In words, the density () of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance. [42] Contrary to the long-standing view that they are carbon neutral, mature forests can continue to accumulate carbon[43] and remain valuable carbon sinks, helping to maintain the carbon balance of Earth's atmosphere. There are few studies of the health effects of long-term continuous CO2 exposure on humans and animals at levels below 1%. Its concentration in Earth's pre-industrial atmosphere since late in the Precambrian has been regulated by organisms and geological phenomena.
