摘要：Mercury concentrations were analyzed in a riparian community from the Cuniã Lake RESEX (a riparian extrativist reserve) at the Madeira river, located in the Amazon region. The studied population age ranged from 2 to 90 years old and hair was used as biomarker. A total of 252 hair samples were collected from fishermen families. Hg concentrations averaged 6.0 (IC95% 5.58-6.58) ± 3.9 μg.g-1 (SD). The fish consumption for adults in this community ranges from 40 to 600 grams per day. The results showed significant gender differences for Hg levels (p-value < 0.05); for male individuals the average was 7.4 (IC 95% 5.56-8.28)±4,5 μg.g-1 and for female individuals was of 5.0 (IC 95% 4.49-5.54) ±3.3 μg.g-1. Studies on neurological symptoms and diet of this community are under way along with other clinical trials and biochemical measurements.
