2015 - 2017
The overall objective of the contract was to develop tools and models to integrate TK data and predict TK parameters for human health, animal health and environmental risk assessment of single and multiple chemicals.
METO was in charge of the development and application of TK tools and models for environmental risk assessment of single and multiple chemicals (Objective 3). The aim was three-fold:
Review available tools and models to integrate TK data in environmentalrisk assessment of chemicals including biologically and physiologically-based models, online tools, software and databases.
Data collection of biological, physiological and toxicological variables to calibrate and develop TK tools and biologically-based models for environmentalrisk assessment of single chemicals.
Development of TK tools and biologically-based models for environmentalrisk assessment of multiple chemicals.
METO developped a generic PBTK model for four species of fish, rainbow trout, three-spined stickleback, fathead minnow and zebrafish. The PBTK model was applied to ten single substances (Grech et al., 2019).
Toxicokinetic interactions were included in the PBTK model for risk assessment of multiple chemicals. Three case studies of mixtures were selected, melamine and cyanuric acid, chlorpyrifos and atrazine, chlorpyrifos and pyrethroids.
