This study reports for the first time, the Hg concentrations in the fish fauna of the Tartarugalzinho river basin - an important gold mining region in Amapa State, Northern Amazon - and evaluates human exposure to Hg due to fish consumption in the area. We analyzed 16 fish species (carnivorous and omnivorous) common in the aquatic environment of the Tartarugalzinho area and which are mostly consumed by the local population. Mercury concentrations in fish ranged from 35 ug.kg-1 to 1,225 ug.kg-1. Among the analyzed fish, 8 species (50%) presented Hg concentrations higher than 500 ug/kg-1, the U.S. Food and Drug Administration (FDA) Action Level for concentration of Hg in fish. No statistical difference was observed between Hg mean concentrations in carnivorous and omnivorous fish. Within a given species, Hg concentrations were positively correlated with fish size or weight. The Hg concentration ratio between fish and water showed values higher than 50,000. Human exposure was estimated through the daily Hg intake obtained throught interviews with the local population on the amount and species of fish consumed and the Hg concentrations in the fish. The estimated average daily intake was 114 ug.day-1. This amount is approximately one-half of the WHO recommended provisional tolerable Hg weekly intake. At screening level, it assumes that there is a level of exposure (e.g, USEPA's RfD = Reference of Dose) below which it is unlikely for even sensitive population to experience adverse health effetcs. The estimated exposure level for adult humans (1.6 ug.kg-1.day-1) was nearly 5 times greater than Hg RfD (0.3 ug.kg1.day-1). The results suggest a wideespread Hg contamination in the local fish fauna. Due to high fish Hg concentrations and high fish intake by local population, environmental exposure to Hg is also high, presenting risk to population.
