Air pollution is the presence of substances in the atmosphere that are harmful to humans and other living beings, or cause damage to the environment. Air pollution can be chemical, physical or biological. [1]
A more recent proposal uses a simple power equation, Toxicity Index (TI) = t 2 × P O 2 c, where t is time and c is the power term. This was derived from the chemical reactions producing reactive oxygen or nitrogen species, and has been shown to give good predictions for CNS toxicity with c = 6.8 and for pulmonary toxicity for c = 4.57.
Various definitions of pollution exist, which may or may not recognize certain types, such as noise pollution or greenhouse gases.The United States Environmental Protection Administration defines pollution as "Any substances in water, soil, or air that degrade the natural quality of the environment, offend the senses of sight, taste, or smell, or cause a health hazard.

It will be quicker to reach net-zero emissions for CO 2 alone rather than CO 2 plus other greenhouse gases like methane, nitrous oxide and fluorinated gases. [22] The net-zero target date for non-CO 2 emissions is later partly because modellers assume that some of these emissions such as methane from farming are harder to phase out. [22]
The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).
