Agrochemical Exposure Assessment
The use of pesticides in agriculture can produce a series of harmful risks to the natural environment, for example, pesticides may leach into groundwater and affect the health of aquatic organisms. Therefore, before the registration of pesticides, environmental risk assessment can provide a scientific basis for the safe use of pesticides, the safety and security of agricultural product quality and ecological environment protection. Exposure assessment plays an important role in the environmental risk assessment of pesticides. BOC Sciences has introduced a series of agrochemical exposure assessment tools to estimate exposure levels. The models and methods we use are applicable to a wide range of agrochemical exposures for ecological and human health risk assessment.
Features of Our Services
- Defensible and transparent exposure assessment within the regulatory framework
- Assessment of the potential risks of pesticides by integrating toxicity test data for different active ingredients of agrochemical species and established exposure scenarios
- Application of the best scientific methods and data sets to address the most challenging agrochemical exposure issues for both ecological and human health risk assessments
