E-fate and exposure

Efate and exposure

Supporting you with environmental fate and exposure modelling:

  • Specialists in environmental fate and behaviour dossier sections
  • Predicted environmental concentrations (PEC) using standard regulatory modelling for all directives, uses, sources, exposure pathways, environmental compartments and receptors according to EU guidelines using, for example, the FOCUS surface water and groundwater models (PRZM, MACRO, TOXSWA, PEARL, PELMO, SWAN and VFSMOD), MED-RICE, EUSES, SimpleTreat, ECPA-LET, DEPOMOD and MAMPEC
  • Conducting regulatory modelling to zonal and national guidelines using, for example, UK POEM, HARDSPEC, UK higher-tier drainflow, GeoPEARL, GEMS, FROGS and EVA
  • Design, characterisation and implementation of higher-tier exposure scenarios for risk refinement
  • Kinetic analysis to derive environmental fate endpoints
  • Assessment of exposure from the redeposition of plant protection products
  • Generation and use of field- and laboratory-generated data, or literature, spatial or meta-analysis data to refine default model parameters or improve mitigation-measure effectiveness values
  • Spatially distributed, probabilistic and catchment-scale exposure modelling and risk assessments
  • Novel modelling approaches, for example, air dispersion modelling using ADMS coupling exposure models with effects and ecological models
  • Inverse modelling of field fate or leaching and lysimeter studies
  • Software development facilitating bespoke and higher-tier exposure scenarios and risk assessments
  • Data gap analysis according to EU requirements
  • Preparation of draft registration report (dRR) zonal dossiers and national addenda
  • Preparation of Annex I active substance and product dossiers
  • Discussions, liaison and strategy development with authorities
  • Study monitoring and programme management
  • Post-submission support

With our in-house field-fate team, we can design, deliver and interpret higher-tier studies to good-laboratory-practice-standards (GLP) that address specific regulatory concerns, including:

  • field leaching and dissipation studies
  • drainflow and runoff evaluations
  • testing infield and edge-of-field mitigation options
  • hard surface and farmyard losses
  • shallow and deep groundwater monitoring
  • volatilisation and redeposition studies
  • replicated plot studies using hydrologically isolated plot facilities
  • spray drift evaluation and testing of drift reduction technologies
  • crop interception and wash-off studies
  • field fate investigations
  • multi-site regulatory studies

CEA has a well-earned reputation for providing higher tier, non-standard support for challenging products in an increasingly demanding regulatory environment. We also provide specialist policy advice and research to government clients.

Our unique combination of expertise and experience means that our clients have access to a wide breadth of industry and regulatory specialists throughout their projects.
