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.

Test results by chemical family (see each chemical)
1 of 1 found
Forms from mercury, a pollutant from coal-fired power plants and other sources. Methylmercury accumulates in seafood and harms brain development and function.
