They may accumulate in sediments, plants, and aquatic organisms, disrupting the delicate balance of the ecosystem.<br> Methods: This study attempted to estimate the concentration of PTEs in shrimp tissue and estimate potential health risks in consumers among international databases, including Scopus, PubMed, Embase, and Web of Science, from January 2000 to March 20 2023. Furthermore, non-carcinogenic and carcinogenic risks for Iranian adult and child consumers were calculated using the Target hazard quotient (THQ) and Cancer Risk (CR).<br> Results: The rank order of PTEs due to THQ in adults was Methyl Hg (0.27) > Cd (0.13) > Ni (0.07) > Inorganic As (0.04) > Cu (0.03) > Pb (0.02), and for children Methyl Hg (1.28) > Cd (0.62) > Ni (0.35) > Inorganic As (0.20) > Cu (0.15) > Pb (0.11). TTHQ for the adults and children was 0.58 and 2.73, respectively. Besides, the mean CR in adults and children regarding inorganic As was 2.00E-5 and 7.98E-6, respectively. On the other hand, the total non carcinogenic risk showed that children could be at considerable risk.<br> Conclusion: The carcinogenic risk of inorganic As was acceptable (CR < 1E-4) for adults and children. As a result, health and environmental authorities in Iran and other nearby regions must continually monitor the levels of PTEs in shrimp muscle tissue and implement policies to reduce the PTE pollution of the Persian Gulf and the Sea of Oman.</div> Carcinogens, Cadmium, Shrimp, Heavy metals, Risk assessment 1 15 http://ehemj.com/browse.php?a_code=A-10-1-438&slc_lang=en&sid=1 Yadolah Fakhri Ya.fakhri@gmail.com 100319475328460021724 100319475328460021724 Yes Correspondence to: Food Health Research Center, Hormozgan University of Medical Sciences, Bandar Abbas, Iran Zohreh Kamari zohreh2310@gmail.com 100319475328460021725 100319475328460021725 No Food Health Research Center, Hormozgan University of Medical Sciences, Bandar Abbas, Iran Maryam Sarkhosh marya.sarkhosh@yahoo.com 100319475328460021726 100319475328460021726 No Department of Environmental Health Engineering, School of Health, Mashhad University of Medical Sciences, Mashhad, Iran Nayera Naimi NayeNaimi@YAGOO.COM 100319475328460021727 100319475328460021727 No Department of Environmental Health Engineering, School of Public Health, North Khorasan University of Medical Sciences, Bojnurd, Iran Abotaleb Bay abotaleb_bay@yahoo.com 100319475328460021728 100319475328460021728 No Environmental Health Research Center, Golestan University of Medical Sciences, Golestan, Iran
