Organophosphate Exposure Levels from Domestic and Occupational Use

People may be exposed to pesticides from use at home (eg pet treatments) or in the workplace (eg agricultural workers). Given the toxic nature of many pesticides, regulations are in place to limit exposure. However, concerns remain that exposure at levels below current recommended limits may still have health consequences. For example, some studies have reported that low level occupational exposure to organophosphate pesticides is associated with neuropsychiatric and cognitive problems.

The aim of this study is to determine if acute or chronic pesticide use at home or at work can lead to cognitive changes. Individuals that use or may be exposed to pesticides at home or at work will be assessed using a series of cognitive tests.

The evidence gathered will be used to inform policy and to determine if current regulations and guidance are adequate to limit exposure and protect public health.
