Air and Pesticides
Air quality is a measure of the amount of pollutants in our atmosphere, which includes indoor and outdoor air. Pesticides in agriculture and urban settings have the potential to contaminate our air, affecting human, animal and plant health. Some pesticide ingredients stay in the atmosphere for only a short period of time, while others can last longer. Pesticides released into the air can settle to the ground, be broken down by sun light and water in the atmosphere, or dissipate into the surrounding air.

- Use IPM practices to control pests
- Monitor the weather when applying pesticides; avoid very hot or windy days
- Consider staying inside with doors and windows closed when pesticides are being applied nearby
How can I find out about my air quality?
