The order of metal
contamination in the fish organs was as follow: gills >
skin > muscles. Gills accumulated the highest level of
Zn (47.41-136.17), followed by Cu (10.51-16.52), Pb
(6.44-10.94), and Cd (2.33-6.06), all measured in μg/g
dry weight. The high content of metals in gill tissues
can be attributed to the fact that fish gills play a distinct
