Abstract

The conclusion of Morris et al. (2006) that “Exposure to Pfiesteria Species in Estuarine Waters Is Not a Risk Factor for Illness” is unsupported because a) a description of Pfiesteria-related fish kills in the Chesapeake estuaries during 1999–2002 was omitted; b) quantitative data on Pfiesteria were not collected; c) data on visual contrast sensitivity (VCS) were collected but not reported; d) a comprehensive list of other results was not presented; and e) data were lost due to a 30% attrition rate. These data are needed to justify or negate the conclusion.

Abstract

Epidemiologic studies commonly use mercury (Hg) level in hair as a valid proxy to estimate human exposure to methylmercury (MeHg) through fish consumption. This study presents the results yielded by a complete data set on fish consumption habits, Hg levels in edible fish resources, and corresponding Hg accumulation in hair, gathered in three distinct communities of eastern Canada. For one of these communities, the average hair Hg concentration was 14 times less than the expected value based on calculated daily oral exposure and current knowledge of MeHg metabolism. This finding could be explained by differences in specific genetic characteristics and/or interactive effects of other dietary components.
