Abstract
ABSTRACT Total Hg concentrations were determined in muscle tissue of some fishes with different feeding habits (12 fish species) obtained from the main fishing locations along the Alexandria coast, a region particularly impacted by historic industrial Hg activities. Health risks to human via dietary intake of the edible portion of fish were assessed by the target hazard quotients (THQs). Mercury maximum concentrations corresponding to fish muscle tissue were found in L. mormyrus, S. rivulatus, and S. luridus (3.56, 2.94, and 1.35 μg g−1 wet weight, respectively). Thence most of these three species bass (75% of L. mormyrus, 76% of S. rivulatus, and 54% of S. luridus) were greater than a 0.47 μg g−1 threshold corresponding to a 1 meal per month consumption limit. M. cephalus, S. aurita, S. chrysotaenia, B. boops, and A. djedaba bass (100%) were less than a 0.12 μg g−1 threshold corresponding to a 4 meals per month safe consumption limit. Mercury THQs values, ranging from 0.11–1.76, were of concern. In particular, the health risk was mainly ascribed to consumption of S. rivulatus (1.72) and L. mormyrus (1.76), although also the TEQs values caused by consuming S. luridus (0.64) were rather high, being close to 1.
