Biocides Risk Assessment

Specialist modelling

 
Risk assessment is the pillar of chemical regulation that is concerned with the protection of man and the environment. It covers the life cycle of a substance from manufacture through use and emissions to disposal, accounting for its properties, stability and effects at each stage. Risk assessment is mandatory for the notification of new chemicals and in the registrations of plant protection products (Pesticide Directive 91/414/EC and Regulation (EC) No 1107/2009,) products containing biocides (Biocide Product Directive 98/8/EC) and also part of the Chemical Safety Assessment in the REACH regulation. Enviresearch Ltd can perform both human health and environmental risk assessments.
 
Expensive test data can be worthless without a thorough understanding of risk assessment procedures. Our risk assessment are based on two guiding principles: we make the best use of your toxicity data and we make the most appropriate assessment of exposure. Risk assessment is carried out using a tiered approach. If the first ter risk assessment fails, Enviresearch Ltd has the skills and experience to carry out higher tier refinements.
Examples of the models that we use in the exposure assessment as part of the risk assessment includes:
 
  • FOCUS ground water
  • FOCUS surface water
  • SWAN (higher tier surface water)
  • MACRO 5 and WEBFRAM (probabilistic higher tier)
  • HardSPEC (Surface water and ground water)
  • ModelMaker (kintetics of transformation)
  • EUSES & ECETOC TRA (risk to human and the environment)
  • EASE (occupational exposure)
  • Bespoke models specific to clients

Parameters describing transformation rates are a requirement by regulatory authorities for use in models to predict environmental concentrations of chemicals. These predictions support the environmental and human health risk assessments needed for the registration. Using equations representing transformation processes accepted by regulatory agencies, Enviresearch Ltd is able to derive rate parameters from laboratory or field data.
