Decisions on the safe use of chemicals need information on exposure levels. Appropriate measurements are not always available and can be difficult to obtain. Exposure modelling therefore plays an important role in risk assessment.
The lack of useful measured data makes exposure modelling crucial in risk assessment. Several generic exposure models are available for regulatory risk assessments. These are usually geared towards specific legislation, such as REACH, BPD or pesticides. Pragmatic qualitative models for SMEs (control banding) are also in widespread use. Proper use of existing models depends on the experience of the user. It is essential to understand the exposure situations and the aim of the exposure assessment as well to have an in-depth knowledge of the available models if valid and accurate exposure estimates are to be obtained in an efficient way. So if you want exposure assessments and need exposure modelling, you must use the appropriate expertise and tools.
Why TNO Triskelion?
With TNO and other knowledge institutes, we translate scientific knowledge on exposure modifiers, operational conditions and risk management measures into models and exposure estimates.
Our models for biocides, pesticides, REACH and the Chemical Agents Directive include BEAT, RISKOFDERM, Stoffenmanager and ART.
We contribute to various directive documents
We provide in-company and free entrance training on human exposure assessment and modelling.
Our critical model evaluation enables model developers and users alike to improve their exposure modelling.
We have made model estimates for hundreds of exposure scenarios.
Your human exposure modelling needs are best served by TNO Triskelion’s expert input.
