The main aim of this study was to biomonitor mercury (Hg), arsenic (As), cadmium (Cd), lead (Pb) and copper (Cu) concentrations in the Arvand River using Heteropnestis fossilis and Parasesarma persicum Comparison of heavy metals among the stations indicated that the concentrations of Hg, As, Cd, Cu and Pb in sediment samples were apparently different among the stations. The results of linear regression analyses showed that there were significant correlations (p < 0.05) between Hg, As and Pb elements in sediment and hepatopancreas of P. persicum and between As in sediment and liver of H. fossilis These findings showed that P. persicum could be considered as a biomonitor of Hg, As and Pb and H. fossilis as a biomonitor of As contamination in sediment of the Arvand River.
本研究的主要目的是利用化石异腹蟹（Heteropnestis fossilis）和波斯相手蟹（Parasesarma persicum）对阿凡德河中的汞（Hg）、砷（As）、镉（Cd）、铅（Pb）和铜（Cu）浓度进行生物监测。各监测站之间重金属的比较表明，沉积物样本中Hg、As、Cd、Cu和Pb的浓度在各监测站之间存在明显差异。线性回归分析结果表明，沉积物中的Hg、As和Pb元素与波斯相手蟹肝胰腺中的相应元素之间以及沉积物中的As与化石异腹蟹肝脏中的As之间存在显著相关性（p < 0.05）。这些发现表明，波斯相手蟹可被视为阿凡德河沉积物中Hg、As和Pb的生物监测指标，而化石异腹蟹可作为沉积物中As污染的生物监测指标。
