Kinetic Analyses

We conduct kinetic analyses of laboratory or field dissipation studies to establish endpoints for the exposure and risk assessment.

Kinetic analyses of laboratory or field dissipation studies

Kinetic analyses

Kinetic analyses of laboratory or field dissipation studies reveal the degradation pattern and metabolism scheme of active substances (SFO, DFOP, FOMC, HS). The estimation of half-live values (DegT50 / DisT50) for parent substances and relevant metabolites is necessary for subsequent exposure modelling.

We provide support for standard kinetic analyses of soil and water sediment studies according to FOCUS (2006) and EFSA (2014) and we develop tailor-made models.

  • Soil, water-sediment studies
  • Lab. or field trials, incl. normalisation
  • CAKE, KinGUI, mkin or other software
