ABSTRACT

Background and objective of the study: The presence of mercury in fish that are part of human feeding is a public health problem; the main species that form the Mexican capture for direct human consumption such as guachinango, mojarra, catfish, sea bass and sawfish are the ones that represent greater sales and consumption nationwide. The objective of the study was to determine if there is presence and estimate the concentration of total mercury in four species of fish that is commercialized in the Metropolitan Area of Monterrey, Nuevo León. Relevant results: The highest concentrations were found in the catfish (Ameiurusmelas) (0.3361 ± 0.3336), while in the Scomberomorus sierra (0.1965 ± 0.2463), Robalo (Dicentrarchuslabrax) (0.1567 ± 0.0906) and Mojarra (Oreochromisniloticu) (0.2380 ± 0.1881) had lower concentrations of total mercury. Impact of the application of research results on the improvement of health care: The estimated average HgT did not exceed the NOM 031 SSA1 1993, however, in some specimens if the value of the NOM was exceeded. It should be remembered that the absorbed mercury accumulates in the human organism with the described health consequences. Given the above, the control in the disposal of contaminated waste and the determinations of this metal in this food product should be considered as activities relevant to the public health of the population.
