Extensive and diverse expertise

Our staff has extensive and diverse expertise which enables the use of a wide range of effective strategies to pass ecotoxicological assessments. Many have considerable experience working in a laboratory setting under GLP, in addition to developing bespoke tests to address specific questions of exposure and effects. Meanwhile, others have a strong ecological and modelling background to perform the standard risk assessments and refine details when necessary to really put product usage into an ecological context.

We use this experience and our understanding of living systems to address the risk to non-target, beneficial organisms following the use of plant protection products in line with the requirements of EU Directive 1107/2009. We conduct standard and higher-tier risk assessments on the range of taxa in compliance with current guidance, harmonisation documents and national regulations.

Our extensive experience in carrying out accurate data gap analysis and writing study summaries supports complete and effective dossier submissions. We also evaluate and reply to authority requests and provide advice and tailor-made strategies to meet specific regulatory requirements. Particularly, we have considerable experience in population modelling development and application within the context of plant protection products and endocrine disruption assessment.
