Níveis de mercúrio em peixes consumidos pela comunidade indígena de Sai Cinza na Reserva Munduruku, Município de Jacareacanga, Estado do Pará, Brasil
Open accessAbstract
O estudo consiste em avaliar os níveis de mercúrio no pescado consumido pela comunidade indígena de Sai Cinza (Reserva Munduruku) no Estado do Pará, e associá-los com os hábitos de consumo da população. Um total de oitenta espécimes de peixes foram capturados. As determinações de Hg foram realizadas por absorção atômica. A concentração média de Hg nas espécies carnívoras foi de 0,293 µg/g (DP = 0,104) enquanto nas não carnívoras foi de 0,112 µg/g (DP = 0,036). As espécies referidas como de maior consumo ente os 330 indivíduos entrevistados foram: tucunaré, pacu, jaraqui, traíra, aracu, matrinchã e caratinga. As espécies com concentrações mais elevadas de Hg foram tucunaré e traíra, que estão entre os peixes mais consumidos. A freqüência de consumo constitui-se num fator importante na avaliação de risco de contaminação por mercúrio em comunidades que não têm outras alternativas de alimentação.

Fish consumption among Munduruku indigenous people can be considered high, at least three meals per day, varying slightly between different groups.
“On the other hand, fish consumption among Munduruku indigenous people can be considered high (at least three meals per day), varying slightly between different groups [56,58,59].”

The Resultados passage (page not specified in the excerpt) reports that fish was a daily dietary staple for all 330 interviewees in Sai Cinza and was eaten at least three times a day. It does not compare consumption between different Munduruku groups or establish that it varies slightly between them. (LLM, conf=0.84)
Experimental — accuracy not yet measuredBrabo et al. observed that piscivorous species had mean mercury levels of 0.293 μg/g, while non-piscivorous species had average mercury levels equal to 0.112 μg/g in the Sai Cinza region.
“Brabo et al. [56] investigated fish contamination in the Sai Cinza region, also inhabited by indigenous Munduruku. They observed that the piscivorous species had mean mercury levels of 0.293 µg/g, while the non-piscivorous species had average mercury levels equal to 0.112 µg/g.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
