Abstract

Amphibians, which can live in aquatic and terrestrial environments, are a good indicator of pollution in these areas. Although frog legs are consumed in many cultural cuisines, they are rarely used in studies of metal accumulation. Because of its usage in the human diet, indeed, it is an important tissue for evaluating metal accumulation from the environment. Herein, the quantities of trace elements (Cd, Pb, Cu, Zn, As, Co, Cr, Ni, Mn, V) were measured in the edible tissues (muscles) of an amphibian species by sampling from two frog farms in Turkey. Pelophylax ridibundus, which is an aquatic species that is thought to be able to absorb pollution from its habitat, was used in the study.It was aimed to assess possible health hazards for humans by frog legs consumption comparing with the toxicological limit values including provisional tolerable weekly intake (PTWI), target hazard quotient (THQ), and Hazard Index (HI). In general, the average values (µg kg−1) of trace elements were Zn (3.437.62)> Pb (69.22)> Cu (66.72)> As (24.24)> Cr (11.47)> Ni (6.94)> Cd (6.51)> Co (2.97). The results showed that it did not exceed the maximum risk limit and that its edible tissues did not have a potential carcinogenic health risk in terms of human health.
