air icon The Air Exposure Review is a scientific assessment that describes community exposures and associated risks to human health from chemicals in the outdoor air in the Sarnia area. This will involve reviewing monitored and modelled data for relevant air chemicals in the area and determining what health risks are associated with chemicals in outdoor air. The results of the Air Exposure Review will help us to understand links between environment and health risk and can be used by public health agencies in evaluating health outcomes in the community (e.g. disease rates of asthma, cancer etc.).

The ministry hired a consulting team (Intrinsik, CanNorth, 4 Directions of Conservation) to conduct the Air Exposure Review and formed a Government Air Exposure Review Panel to support the quality, accuracy, and relevance of the consultant’s deliverables.
