carbon dioxide

Silos that store grain and feed are among the most deadly confined spaces on farms, with hazards that include gases produced by fermenting fodder such as carbon dioxide and nitrogen oxide.

Handling and storage of animal manure are a leading category of deadly hazards on farms because decomposing manure releases gases such as carbon dioxide, methane, ammonia and hydrogen sulfide that can displace available oxygen.

Most commercial ships use heavy fuel oil, which releases carbon dioxide and other air pollutants when burned.

In 2009 the U.S. Environmental Protection Agency issued an endangerment finding that concluded carbon dioxide and other greenhouse gases threaten public health and welfare, which serves as a legal basis for many U.S. climate regulations.

Metal-organic frameworks are a class of molecular constructions that can be used to harvest water from desert air, capture carbon dioxide, store toxic gases, and catalyze chemical reactions.

Potential applications of MOFs include capturing carbon dioxide from air, extracting water from humid air in arid environments, and functioning as carriers for targeted drug delivery.

The ocean absorbs about one-third of annual anthropogenic carbon dioxide emissions.

When carbon dioxide dissolves in seawater it reacts to form bicarbonate and hydrogen ions, and the resulting increase in hydrogen ions lowers seawater pH (increasing acidity), which can harm marine organisms and reduce the ocean's future capacity to take up carbon.

Tropical rainforests absorb large amounts of carbon dioxide, which contributes to regulating the global climate.

Carbon dioxide emitted from the combustion of fossil fuels can remain in the atmosphere for at least a century.
