This study analyzed the concentrations (dry weight basis) and bioaccumulation factors (BAF) of copper (Cu), lead (Pb), cadmium (Cd), and mercury (Hg) in pre- and post-monsoon samples at five stations (Chabahar, Darak, Gowatr, Jask, and Pozm) in the Gulf of Oman. For this purpose, ten samples of hooded oyster Saccostrea cucullata, brown algae Sargassum ilicifolium, and Indian white shrimp Penaeus indicus were collected once a month during fall and spring (a total of 60 samples were obtained from each species per station). Additionally, sediment samples were collected three times a month during these two seasons (ten samples per each season). Our results indicated that metal concentrations were lower than the maximum permitted limit in the sediment across the tested stations (<0.42 ppm). In both seasons, the highest concentrations of metals in the sediment were found in Chabahar, followed by Jask. The concentration of Hg was higher in the Indian white shrimp (0.16 ppm) and hooded oyster (0.20 ppm) than in the standard (0.10 ppm), while for other metals and tissues the concentrations were lower than the standard level. Also, BAF of Hg was higher than the standard permissible level in Jask(spring: 109.71%) and Pozm station (spring: 123.12%, fall: 125.76%). Except for Cd and Cu at the Chabahar station, the monsoon did not have any significant effect on metal concentrations and bioaccumulation. Preventive measures and management strategies are required as these concentrations and BAF of metals can become an actual threat to the environment and human health in this area.

这项研究分析了五个站点（Chabahar）季风前后样品中铜（Cu），铅（Pb），镉（Cd）和汞（Hg）的浓度（以干重计）和生物富集因子（BAF） ，达拉克，Gowatr，Jask和波兹姆）。为此，取十个带帽牡蛎Saccostrea cucullata，褐藻Sargassum ilicifolium和印度白对虾印度对虾样品秋季和春季每个月收集一次（每个站点每个物种总共获得60个样本）。此外，在这两个季节中，每月要收集三次沉积物样品（每个季节十个样品）。我们的结果表明，在所有测试站中，金属浓度均低于沉积物中的最大允许限值（<0.42 ppm）。在两个季节中，沙巴哈尔沉积物中的金属含量最高，其次是贾斯克。印度白虾（0.16 ppm）和带帽牡蛎（0.20 ppm）中的汞含量高于标准品（0.10 ppm）中的汞含量，而其他金属和组织中的汞含量均低于标准水平。此外，汞的BAF高于Jask（春季：109.71％）和Pozm站（春季：123.12％，下降：）的标准允许水平。125.76％）。除Chabahar站的Cd和Cu以外，季风对金属浓度和生物蓄积没有显着影响。需要采取预防措施和管理策略，因为这些浓度和金属的BAF可能对该地区的环境和人类健康构成实际威胁。
