Risk assessment

Risk assessment of chemicals & (nano)materials

Each manufactured chemical substance, drug, or (nano)material that enters the natural environment and the human body may pose a risk on many levels. It is important not only to design consciously but also to predict the behavior and fate of chemicals effectively.

For years, QSAR Lab experts have specialized in developing forecasting models that enable risk assessment posed by new materials (including nanomaterials) to the natural environment and human health and life.

A chemical risk assessment aims to fully understand the nature and likelihood of a chemical’s potential adverse effects on health or the environment. It takes into account both hazard and exposure.

QSAR Lab provides a comprehensive risk assessment of a given substance, covering the three most essential elements:

  • Hazard prediction
    Predicting dose-response relationships (LD50/LC50, EC50, TD50, etc.), determining the relationship between the amount of exposure to a hazard and the probability and severity of side effects.
  • Exposure assessment
    Determining the extent to which exposure actually occurs.
  • Risk characteristics
    Combining hazard prediction and exposure assessment information to reach conclusions on the nature and magnitude of the risk and, if appropriate, implement additional risk management measures.

Risk assessment currently forms the basis for regulatory decisions regarding industrial chemicals, pesticides, pharmaceuticals, cosmetics, food additives, and food contact substances in developed countries.
