520 |a“The Canadian Mercury Science Assessment is the first comprehensive scientific evaluation and synthesis of mercury (Hg) in the Canadian environment. The Clean Air Regulatory Agenda (CARA) Mercury Science Program was developed in 2007 to establish the scientific knowledge base to support regulatory decision-making for Hg; this assessment was a key outcome of that program. This assessment report has shown the breadth and depth of scientific research that has been undertaken in Canada on Hg. Each chapter shows the complex processes that Hg goes through in the ecosystem and the impacts that Hg can have on the environment. Overall findings from this assessment have shown that Hg remains a risk to Canadian ecosystems and human health. Canada has been successful at conducting research and monitoring on the environmental and health processes of mercury over the past decades; however, many unknowns remain. This scientific assessment on Hg in Canada has led to the recognition of several detailed priority gaps of knowledge and has provided scientific recommendations for focus areas and future research"--Ch. 15, intro., p. 787.
