[Mercury content in fish]

Studied was the content of mercury in certain fish species from ocean and the Black Sea catch (mackerel, scad, and merluccius), sold on the home markets. The study of samples of merluccius revealed that the average level of mercury was 0.088 ppm, the deviations being from 0.036 ppm up to 0.16 ppm. In mackerel samples mercury averaged 0.075 ppm, with deviations of 0.04 ppm to 0.013 ppm. And in scad mercury was shown to vary from 0.03 ppm to 0.085, an average of 0.059 ppm. Mercury in the investigated species of fishes was considerably lower than the standards of the World Health Organization and the Food and Agriculture Organization and the maximum admissible tolerance in USA, Canada, and France.
