In the region of the Tocantins river communities with high fish consumption through diet, located away from the gold mining area in the city of Empress of Maranhão may be exposed to mercury in view of the influence of other factors including environmental contaminants activities and hydroelectric potential of forest fires in this region. The aim of this study was to assess mercury exposure in families of fishermen District Beira Rio, Imperatriz-Maranhão. We conducted a cross-sectional study involving fishing families living in the community Beira Rio, located on the banks of the Tocantins River in the city of Imperatriz, Maranhão. The socio-demographic profile was common to the general Brazilian population and similar to the local population located in other basins. The profile food not fled the rule of dietary patterns of riparian and fish as the main source of dietary protein. The piscivorous species showed significant differences (p <0.01) compared to species herbivorous / omnivorous and detrívoras studied and zooplanctófaga species showed significant differences (p <0.01) compared the two species previously mentioned. Among the 25 families evaluated the lowest average concentration of Hgtotal / family was 0.186 ± 0.043 mg / g and 5.477 ± 2.896 was greater ug / g. Even within acceptable limits, the average concentration of Hgtotal presented by men (1.01 ppm 1.97) was higher than for women (0.69 ppm 0.82) (p <0.05). Conclude that fishing families of Empress have low levels of mercury exposure as a result of dietary intake of fish with low levels of contamination, including fish-eating species, which were below the safety limit for human consumption established by Brazilian standards, serving reference to other studies.

Introduction: Significant levels of mercury exposure associated with fish intake have been demonstrated in riverine populations living in areas of mineral exploration as the basin of Tapajós and Madeira. In the Tocantins region, although few studies, there is no evidence of human exposure through food. Objective: To assess the levels of exposure to mercury in resident fishermen families in the riverside area of the middle Tocantins and to quantify the levels in fish consumed by these families. Methods: We conducted a cross‑sectional study involving families of Beira Rio community fishermen, located on the Tocantins riverbanks in the city of Imperatriz, Maranhão. Brazil. Data were collected from socio‑demographic and food profile, as well as samples of fish and hair, which were analyzed by atomic absorption spectrophotometry. Results: The socio‑demographic profile of families studied was common to the local population located in other basins. The food profile did not run the default rule, with the fish being the primary dietary protein source. The species of piscivorous and zooplancton habits had the highest mercury concentrations, and the mean values were 0.2775 µg/g in fish‑dog and 0.1360 µg/g in mapará. Among the 25 families evaluated, the lowest average concentration of family was 0.186 ± 0.043 µg/g and the higher was 5.477 ± 2.896 µg/g. Conclusion: Fishing families have low mercury exposure levels in the same order of magnitude, probably because of the food consumption of fish, including piscivorous species, which were found to be below the safe upper limit for human consumption established by Brazilian standards. This serves as a reference for other studies.
