Evaluation of arsenic contamination from mining exploration in the eastern Amazon ; Evaluación de la contaminación por arsénico de la exploración minera en la Amazonía oriental

Environmental exposure to Arsenic (As) has been increasing over time, either naturally or through anthropic action, this process causes concern in the population as to health risks. Thus, the present study aimed to list the scientific information regarding arsenic contamination in the city of Santana-AP, through a review of the literature in the Capes Periodic Portal, Scielo, Academic Google and PubMed database. Ten studies were identified and analyzed, the only ones being published in this region for the study of As concentration. After analyzing the results, the concentration of As in the water that the community of Elesbão consumes were within the established parameters of <10 μg.L-1. However, the concentration in the soil (50 mg.kg-1) and hair (1.0 mg.kg-1) of this population were above the reference value. This is justified by the level of As total identified in fish and shrimp, causing a possible biomagnification process. Therefore, it is necessary to study all the possible variables of the route of contamination by As in the focus region of the present study, since the divergences of results raise doubts about the level of contamination. Thus, this review will serve as a prerequisite for the evaluation of publications from other regions that have undergone or suffer anthropogenic actions. ; La exposición ambiental al Arsénico (AS) ha ido aumentando con el tiempo, ya sea de forma natural o por acción antrópica, este proceso genera preocupación en la población en cuanto a los riesgos para la salud. Por lo tanto, el presente estudio tuvo como objetivo enumerar las informaciones científicas sobre la contaminación por arsénico en la ciudad de Santana-AP, a través de una revisión de la literatura en el Portal de Periódicos da Capes, Scielo, Google Scholar y base de datos PubMed. Se identificaron y analizaron diez trabajos, siendo los únicos publicados en esa región con la concentración As como objeto de estudio.
