Ecotoxicology

The environmental risk assessment for biocidal active substances and biocidal products requires a robust ecotoxicology database to provide an assessment of the effects on indicator species. We have a wide range of experience and expertise in all areas of ecotoxicology.

JSC is actively involved in a number of expert groups developing test guidelines and risk assessment schemes at EU level. We subsequently have practical experience of all levels of ecotoxicological testing, from laboratory through to field. This experience enables us to put together and implement study packages to meet specific project requirements.

If the initial data gap analysis and preliminary risk assessment identify any areas of concern, it will be necessary to refine the assessment, in order to demonstrate acceptability. This may involve consideration of existing information (including generic databases) and further evaluation of the exposure profile in the fate area. It may also be necessary to conduct additional higher tier testing which requires detailed knowledge of the various test organisms and associated methodology, in order to design and implement appropriate customised study designs. JSC has extensive experience of this level of testing. We are additionally able to provide expert interpretation to maximise the benefit of these studies and ensure a successful regulatory outcome.

The environmental risk assessment applies safety factors to the ecotoxicology endpoints, such as toxicity to fish, Daphnia or algae to generate the Predicted No Effect Concentration (PNEC). The ratio between the PEC and PNEC is ultimately used as an indicator of risk, allowing it to be quantified.  If the PEC is less than the PNEC (i.e. ratio < 1), then it is assumed that there is an acceptable risk of effects to the environment.
