Chemicals – spray drift

chemicals spray drift

Sprayed chemicals are extensively used in agriculture and horticulture for control of pests and weeds. This spray can drift over neighbouring properties, waterways and water tanks, this is referred to as spray drift.  Spray drift can affect human, animal and environmental health. Spray drift can affect household and farm water supplies, including tank water.

The health impacts of exposure depend on how and where the chemical is applied, the amount of drift, the weather and the toxicity of the chemical. If you have been exposed to chemical sprays through spray drift, and are concerned, there are a number of agencies you can contact for help.
