Non-dietary human exposure

This guidance provides information on non-dietary exposure risk assessments for plant protection products (PPP) and active substances. It is not intended to be a complete guide but is a source of information relating to topics where advice is frequently sought.

Before PPP are placed on the market, they are assessed to ensure they do not have any harmful effect on human health. One aspect of this risk assessment considers exposure via non-dietary routes, including inhalation, dermal absorption and ingestion.

In a non-dietary exposure risk assessment, the following groups are considered:
