Methylmercury and Contaminant Risk Assessment

The contract seeks to evaluate methylmercury accumulation and associated contaminant risks within freshwater ecosystems, focusing on understanding bioaccumulation pathways and their effects on both ecological health and human populations. This work requires detailed analysis of how methylmercury moves through food webs, including its uptake by aquatic organisms and transfer to top predators and human consumers, with an emphasis on identifying high-risk areas and exposure scenarios. The research must integrate environmental monitoring, chemical analysis, and health risk modeling to provide a comprehensive assessment of contaminant behavior and potential impacts. This subcontract, issued under NAICS code 541620 by the Government of Canada through the Impact Assessment Agency of Canada, is open for proposals with a response deadline of June 12, 2026. The work is to be performed across freshwater systems within Canada, requiring expertise in environmental toxicology, aquatic ecology, and risk assessment methodologies. While no specific set-aside provisions are indicated, applicants must demonstrate the ability to deliver scientifically rigorous results within the scope of contaminant tracking, data interpretation, and health risk characterization to support regulatory and public health decision-making.
