When we talk about greenhouse gases in the general public, we tend to limit ourselves to carbon dioxide, a practical standard into which we can convert all the pollutants that contribute to global warming. Sometimes methane is added, due to its potency and its specificity (the hatchling emits a lot). But we forget, to be practical and not complicate the comments, all the precursors of COtwoThese often short-lived products then degrade to end up, more simply, enriching the atmosphere with carbon.
Among these pollutants, aerosols occupy an important place. Under this generic term are grouped lots of chemical compounds diffused in the form of gas that carry small particles, including the famous PM 2.5 – what we know as fine particles, often cited in urban air quality measurements. These carbon compounds (for the most part) are therefore the main contributors to air pollution, which is harmful to both the environment and human health, as well as to that of animals and plants, including crops that feed us. Aerosols, whether in the form of droplets or particles, are mainly emitted by factories, power plants, vehicle exhaust, etc.
COtwo and particles: two contaminations in one
Today, we dissociate the air pollution that affects us directly, mainly in cities, and c
