about this group:
Tests uncover two extremes in human blood pollution: mercury, the well-studied, ubiquitous power plant pollutant that accumulates in seafood like tuna; and emerging Teflon pollution only now under intense scrutiny by public health officials. In both cases, body burden tests give vital clues to exposure and health risks in a system that fails to require this understanding up front.

Group: EWG Study #5, Teflon and mercury in blood in adults and teens
Found 9 of 14 tested chemicals (8 participants)
The blood of the "EWG Study #5, Teflon and mercury in blood in adults and teens" group contained 9 of 14 industrial compounds, pollutants and other chemicals tested, including chemicals linked to cancer, birth defects and developmental delays, and endocrine system toxicity.

Forms from mercury, a pollutant from coal-fired power plants and other sources. Methylmercury accumulates in seafood and harms brain development and function.
