Abstract

Heavy metal contamination in ecosystems is a significant environmental concern that requires attention. The purpose of this study was to assess the health risks associated with heavy metals in two species of fish, perch, and zalon, found along the southern coast of the Caspian Sea. The accumulation of heavy metals was measured using the atomic absorption method. Health indicators, such as daily and weekly intake estimates, non-carcinogenic potential, and carcinogenic potential, were determined. The daily and weekly intake estimates were found to be below the permissible limit in all samples. The non-carcinogenic potential was less than one, indicating that there is no significant risk. However, some samples showed a carcinogenic risk potential above the acceptable range. Based on the evaluation results of daily and weekly consumption and the non-carcinogenic risk potential of these species, they are considered safe for consumption. However, long-term consumption of heavy metals such as lead, cadmium, cobalt, arsenic, and chromium can increase the risk of cancer. The estimated daily intake for an adult weighing 70 kg was 7.4 for lead and 0.05 for cadmium. The estimated weekly intake was 51.82 for lead and 0.35 for cadmium, respectively.
