Ecotoxicology

Before a pesticide is approved, the risk to non-target organisms must be assessed. This assessment is to ensure that there are no significant long-term changes to the population nor to the function of the ecosystem. Certain other effects may also be unacceptable such as vertebrate mortalities.

The information you provide must be sufficient to allow an assessment of the impact on non-target organisms likely to be at risk from exposure to the active substance and appropriate metabolites.

Classification and labelling

Environmental Hazard Classification and Labelling under CLP Regulation

This is a brief guide to CLP environmental hazard classification and labelling for active substances and 'mixtures' (formulated products).

Environmental Safety Precautions and Risk Mitigation for Plant Protection Products in the UK

Advice regarding the wording on product labels of 'safety precautions' previously required under Annex V to Directive 91/414 and now required under Commission Regulation (EC) No 547/2011. It details the various risk mitigation measures that may be needed, including a more detailed consideration of UK product labelling and risk management strategies for terrestrial (crop dwelling) non-target arthropods.

Research reports

There is a list of research reports useful for ecotoxicology risk assessment.
