This study evaluated the risks of mercury levels in sardines consumed by low-income population in Salvador, Brazil. The results showed that the mercury content in the sampled sardines posed no risks to human health. This study is significant as most sardines in Salvador come from Todos os Santos Bay, which has a history of mercury contamination.
This work reports assessing risks to human health resulting from mercury levels in sardines (Sardinella brasi-liensis), which have been highly consumed by the low-income population from Salvador, Brazil. Mercury was determined using the Direct Mercury Analysis (DMA) in fifty-one commercially acquired samples in seventeen neighborhoods. The mercury content on a wet basis ranged from 0.023 to 0.083 mu g g-1 for an average value of 0.039 mu g g-1. The estimated weekly intake (EWI), target hazard quotient (THQ), and maximum safe consuming quantity (MSCQ) were used in the toxicological assessment, and all these indices denoted that this food does not pose any risks to the human health of the population that consumes it. The development of this work was very significant because most sardines sold in Salvador originate from Todos os Santos Bay, which has a history of mercury contamination.
