    In this study, deep water rose shrimp (Parapenaeus longirostris, H. Lucas 1846) obtained in September 2020 from the Iskenderun Bay and Antalya Bay local fishermen of the Mediterranean Sea were investigated in terms of iron (Fe), copper (Cu), zinc (Zn), manganese (Mn), nickel (Ni), cobalt (Co), aluminum (Al), chromium (Cr), cadmium (Cd), and lead (Pb) bioaccumulation as well as Malondialdehyde (MDA) accumulation levels, and catalase (CAT) activity in their muscle tissues. Human health risks, weekly consumption amounts, and cancer risk assessments for deep water rose shrimp consumed in these two regions were calculated. The highest metal concentration calculated from P. longirostris was Fe (35.976 +/- 2.992 mg kg(-1)) in Antalya, and the lowest concentration wasCd (0.002 +/- 0.001 mg kg(-1)) in the same station. The level of MDA was determined as 11.06 +/- 0.36 nmol mg(-1) protein in Iskenderun station and as 8.63 +/- 0.13 nmol mg(-1) protein in Antalya station while CAT enzyme activity was determinedas 6.6 +/- 0.4 k g(-1) protein and 3.7 +/- 0.15 k g(-1) protein for Iskenderun and Antalya, respectively. According to our results, the metal accumulation caused lipid peroxidation in the muscle tissues of the shrimps studied. Human health risks were determined to be below the estimated weekly consumption (EWI) values and the provisional tolerable weekly intake (PTWI) values determined by European Food Safety Authority (EFSA) and Food and Agriculture Organization/ World Health Organization (FAO/WHO). Target hazard coefficient (THQ) and hazard index (HI) values, which are indicators of non-cancer health risks for the consumer, were calculated as <1. This study shows that Pb, Cr, and Cd bioaccumulations from the two stations do not pose a carcinogenic risk and toxic element concentrations in the muscles of the P. longirostris sold in the Iskenderun and Antalya regions do not pose a health risk for consumers.
