Risk assessment of chemical substances to be revised under CEPA

The Canadian Environmental Protection Act requires scientists to assess the environmental and human health hazards of chemical substances. The Risk Assessment Toolbox is essential for determining risk management measures and preventing potential damage.

Approaches include IRAP, hazard characterization, and ecological risk assessment, taking into account more susceptible subpopulations. The New Substances Notification Regulations are essential for evaluating the ecological and human health risks of substances in Canada. These regulations replace animal testing with new approach methods (NAMs) to enhance prioritization and assessment. Risk management measures must prioritize environmental, life, and human health impacts, requiring the participation of experts and stakeholders.
