Determinação de arsênio total em peixes tainha (Mugil sp.) através da espectrofotometria de absorção molecular. Orientador: George Queiroz de Brito. 2023. 20 f. Trabalho de Conclusão de Curso (Graduação em Farmácia) - Departamento de Farmácia, Universidade Federal do Rio Grande do Norte, Natal, 2023.https://repositorio.ufrn.br/handle/123456789/55760The aquatic ecosystem is considered the most susceptible to pollution, which can be derived from natural sources or as a result of human activity. Toxic agents, such as arsenic (As), are commonly found in the marine environment and traces of them in aquatic organisms. Thus, fish and its derivatives are considered an important source of arsenic exposure and contamination for humans. Therefore, it is necessary to carry out an effective assessment of the concentrations of arsenic and other contaminants in fish meat in order to reduce the risk to the population. In view of the above, the objective of this study was to determine the total arsenic content in three samples of mullet fish (Mugil sp.) purchased commercially in the city of Natal/RN, to verify whether they comply with the limits established by Brazilian legislation. The samples were analyzed in duplicate using the hydride generation technique by molecular absorption spectrophotometry, using the silver diethyldithiocarbamate method. Thus, the results obtained were 0.622, 0.628 and 1.014 μg/g of arsenic, demonstrating that one of the samples analyzed had a total arsenic concentration above the maximum value established by current legislation.ArsênioTainhaContaminaçãoEspectrofotometriaArsenicMullet fishContaminationSpectrophotometrybachelorThesisCNPQ::CIENCIAS DA SAUDE
