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.

Our experienced ecotoxicologists specialise in higher tier risk assessments, working closely with efate, exposure modelling and toxicology colleagues to develop interdisciplinary solutions for the refinement of wildlife risk assessments.

We are able to review complex fate and effects data packages to provide advice on a way forward, designing and co-ordinating studies that meet specific regulatory requirements.

We are experienced in refining problematic risk assessments for difficult groups such as birds and mammals and aquatic organisms, and can 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.

We are also able to undertake endocrine disruptor assessments.

We 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.
