Pesticides in the atmosphere

The air contamination by pesticides is a new component of air pollution that is misinformed. This is due in part to the recent awareness of this form of pollution, lack of standards on pesticides in the air, but also the diversity of active molecules used. Pesticides are intentionally applied to large scale in the environment, destroy the plants considered pests and protect crop plants and crops from attack by insects, fungi, rodents. Pesticides can enter the atmosphere directly in the application but after their filing volatilizing or under the influence of wind. Currently, the lack of any national or European standards on pesticides in the air, authorized associations to monitor the air quality (AASQA) drew up regional lists of molecules to be monitored. All studies conducted by AASQA show, without exception, the presence of pesticides in the atmosphere. The percentage of detecting specific molecules is never zero. It may even reach 100% (when the molecule is observed in all samples).
