This guidance document intends to provide an insight into which pieces of information that are necessary to identify and document an adverse outcome pathway (AOP) and how to present them. The AOP concept has been developed as a means of providing transparent mechanistic justification and weight-of-evidence to reduce uncertainty in the predictions for complex toxicological endpoints.

US Environmental Protection Agency derived the Human health benchmarks for pesticides by applying the health effects data from pesticide registrations to the typical methods used for developing drinking water health advisories. It was developed to enable states, water systems and the public to better determine whether the detection of a pesticide in drinking water or source waters for drinking water may indicate a potential health risk.
