Ecotoxicology and risk assessment

Ecotoxicology and risk assessment

The assessment of the risks to wildlife from potential exposure to plant protection products is a critical part of the evaluation process under the European regulation (EC) No 1107/2009. We specialise in higher tier risk assessments for birds & mammals, aquatic organisms, non-target arthropods, soil organisms, honeybees and non-target plants. Together with in-house expertise in environmental exposure and toxicology, we are able to develop interdisciplinary solutions for the refinement of wildlife risk assessments. We also have an in-house aquatic testing facility, undertaking novel higher tier studies both indoor in laboratories and outdoor in mesocosms.

 

Aquatic ecotox studies (single/multiple spp; indoor/outdoor)

At the forefront in the design and conduct of higher-tier aquatic studies according to the principles of GLP, our ecotoxicologists are well placed to co-ordinate studies to meet challenging regulatory requirements.

Our outdoor facilities, comprising of 99 replicate flat bottomed mesocosms and 100 replicate sloping mesocosms, offer unrivalled flexibility and control by using mesocosm designs that are closely related to real edge of field water bodies. In addition, we continually develop new organism sampling and analysis methods in line with evolving regulatory guidance to ensure the endpoints from our studies are robust and reliable.

In addition to mesocosm studies, we also offer indoor laboratory studies with many invertebrate, plant and algae species, all of which is supported by cutting edge statistical analysis.

Furthermore, we have in-house expertise for the taxonomic identification of freshwater phytoplankton, periphyton, macrophytes, zooplankton and macroinvertebrates to GLP standards, for studies conducted at the CEA facility or externally.

 

Risk assessment

Risk assessments for non-target organisms are conducted by our experienced ecotoxicologists, working closely with efate and modelling colleagues. We are able to review complex fate and effects data packages to provide advice on a way forward, drawing on our backgrounds in contract research to design and co-ordinate studies which meet specific regulatory requirements. We are experienced in refining problematic risk assessments for difficult groups such as birds and mammals and aquatic organisms, and conduct these assessments as stand-alone tasks or as part of dossier submissions. Our experience of industry working groups and government research provides us with an in-depth understanding of risk assessment requirements.

 

Dossier sections

A good dossier provides a clear account of the environmental profile of a plant protection product. Starting with a data gap analysis for the proposed use pattern, we draw on backgrounds in industry and contract research to design and commission the studies required to address any deficiencies identified. Our experienced modellers, environmental fate, and ecotoxicology specialists work together to prepare the environmental sections of the dossier, and this integrated approach allows us to provide the most efficient solution to any areas of concern. Our experience encompasses a range of product types and environmental challenges.
