Investigating the concentration of lead, cadmium and nickel in the muscle tissue of oily sardine fish (Sardinella longiceps) and edible oyster (Saccostrea cucullata) and estimating the risk health assessment (case study: beaches of Bushehr province)
The increase in the consumption of heavy metals in the Persian Gulf is the result of oil release, coastal investments such as refineries and large industrial factories, in fishing and commercial, household industries, as well as agricultural runoff, which is the result of pesticides and pesticides. It is one of the dangers that have made the ecosystem with this threat. Considering the proof of the nutritional value of marine products in the past decades and the need to consume food sources and fatty acids needed by the body, it is necessary to study the increase in the amount of risks caused by the consumption of aquatic products. Considering the importance of treatments related to heavy metals in edible aquatics due to the possibility of the accumulation of these metals, 30 oily sardine fish samples and 30 food samples from the beaches of Bushehr were analyzed. Oily sardines and edible oysters are both for human consumption, and according to the reports of the past few years about the presence of pollutants, including heavy elements, in the waters of the Persian Gulf, it is necessary that these species are healthy for human consumption. Thoroughly tested. The main purpose of this research is to measure the accumulation of lead, cadmium and nickel in the muscles of oily sardines and oysters in the Persian Gulf and its consumption. The composition of lead, cadmium and nickel metals in oily sardine fish muscle was calculated as 0.4327, 0.0192 and 0.0006 respectively and in edible oyster mollusk as 0.7414, 0.0550 and 0.0025 micrograms per weight respectively. A comparative comparison with the standards specified by global organizations such as WHO, FDA and UKMAFF shows that all the following were within the standard. The HQ index was less than 1 for both species, which indicates that the consumption of oily sardines and edible oysters does not pose a serious risk to the health of consumers in terms of lead, cadmium and nickel levels.
