The purpose of this study was to examine the quality of water and fish meat of Sarpa salpa and to determine the water pollution index based on the physicochemical parameters in El-Kala waters, Algeria. The sampling of water and fish was carried out in 2020 at three stations (New Harbor, Maudite Islands, and Messida). The results of pollution index “PIj" calculation at coastal waters El-Kala were classified as lightly polluted (New Harbor and Messida waters) with the pollution index values of 3.24 to 1.33, respectively. It was important to notice that the levels of Cd, and Pb had exceeded the International Security standards in the coastal areas. The values of the bioconcentration factor “BCF" of the whole and of the dosed ETMs oscillate were between 18.31 and 175.41. At the three stations, the distribution of ETMs according to their BCF values were sequenced in the following decreasing order: cadmium˃ lead˃ zinc. The average concentrations of TME in water and fish meat decreased in the following order of stations: New Harbor> Messida> Maudite Islands, regardless of the metal. The analyses carried out made it possible to identify the samples from the New Harbor and Messida stations as the most contaminated with cadmium found in fish and cadmium and lead found in water. The high levels of cadmium and lead in water and fish tissues can be a real indicator of the degree of contamination of the site by these metals.
