Volatilisation: Many pesticides are volatile, which means they readily turn from a liquid to a gas state. This can lead to the release of harmful chemicals into the air, where they can be transported over long distances and contribute to air pollution.
Spray Drift: When pesticides are sprayed, some of the droplets may not reach the target area and instead drift away, potentially contaminating air, soil, and water resources.
Resuspension: Pesticides that have been deposited on soil or plants may be resuspended into the air by wind or human activities, such as tilling.
Atmospheric Chemical Reactions: Some pesticides can react with other chemicals in the atmosphere, forming new compounds that may have different properties and environmental effects.
Ozone Depletion: Certain pesticides, such as methyl bromide, have been found to contribute to the depletion of the ozone layer, which protects the Earth from harmful ultraviolet radiation.
