Fish intake and MeHg exposure in Louisiana anglers.

There is concern that methylmercury (MeHg) exposure assessments among average fish consumers in the United States may underestimate exposures in subpopulations with high intakes of regionally specific fish. Lincoln et al. (p. 245) examined relationships between fish consumption, estimated Hg intake, and measured exposure among recreational anglers in Louisiana. The authors report that 40% of participants had levels > 1 [micro]g/g, which is near the reference dose established by the U.S. Environmental Protection Agency. Fish consumption and Hg intake were positively associated with hair Hg. Participants reported consuming nearly 80 different fish types, many of which ate specific to the region. Unlike the general U.S. population, which acquires most of its Hg from commercial seafood sources, approximately 64% of participants' fish meals and 74% of their estimated Hg intake came from recreationally caught seafood. These results suggest a need for more regionally specific exposure estimates and public health advisories.
