This study aimed to measure the concentrations of lead and cadmium in the muscle tissue of Solen dactylus oyster in Tiab and Sirik areas located in Hormozgan province. To conduct this research, in the summer of 1397, 30 Solen dactylus oysters were collected from each of the mentioned areas and then bioassay operations were performed in the laboratory. Atomic absorption spectrophotometry was used to measure the concentration of lead and cadmium. Atomic absorption spectrophotometry was used to measure the concentration of lead and cadmium. The recorded results for the mean concentrations of lead and cadmium showed that there is a significant difference between Tiab and Siric stations (p≤0.05), And the highest mean concentrations of lead and cadmium were observed in oyster muscle tissue of knife handle, lead (0.761±0.065) and cadmium (0.506 ± 0.75) in the samples of Tiab station, respectively. The results show that factors such as the habitat of Solen dactylus affect the accumulation of heavy metals lead and cadmium, so that Tiab station shows higher pollution than Sirik station. On the other hand, the amount of these heavy metals in the oyster tissue of the knife handle at Tiab station is higher than the standard of the World Health Organization (WHO) and also in the Sirik region, the concentration of lead is lower and the concentration of cadmium is higher than the WHO. It turns out that the consumption of knife oysters both as shrimp food and by humans should be accompanied by health considerations.
