چکیده

Due to having the highest protein and lowest saturated fatty acids, fish and canned fish arethe most abundant and important source of food in Iran and other countries. However,heavy metals like cadmium, tin, mercury, and lead, pollutants from natural and humanactivities, accumulate in these foods and pose serious health risks. Industrialization hasincreased these contaminants in the environment, affecting food safety. Acidic digestion ofcanned fish samples was done. After preparation, atomic absorption spectroscopy was usedto measure the levels of lead, cadmium, mercury. In this research, the average amount oflead, tin, cadmium, and mercury in canned fish samples was reported ۰.۱۸, ۰.۵, ۰.۰۲, and۰.۰۳ ppm, respectively. These levels are all below the maximum limits set by the NationalStandard Institute of Iran. The findings show that current canned fish meets safetystandards for heavy metals. Low concentrations indicate effective contamination controls infishing, processing, and canning. However, ongoing monitoring, strict regulations, andimproved environmental policies are essential to maintain and enhance safety.
