The presence of Hg, Cu, Cr, Cd, Pb, and Zn in clam (Meretrix lyrata) from the East Java Coast (EJC), Indonesia, is reported in this study. Metal levels in clam whole tissues were Zn > Cu > Cr > Pb > Cd > Hg. Cr, Cd, and Pb levels in clam tissue surpassed the tolerated limit for eating and the provisional acceptable weekly intake (PTWI) at numerous places along the EJC. The target hazard quotients (THQs) for Cr, Cd, and Pb were greater than one in several locations, indicating that these metals could be harmful to consumers (particularly non-carcinogenic impacts). Eating clams from this area may be detrimental to human health. Furthermore, target cancer risk (TCR) values for Cr and Cd were greater than 10 in several locations, implying that Cr and Cd could cause cancer in people over the course of a lifetime of exposure.
本研究报告了印度尼西亚东爪哇海岸（EJC）贻贝（Meretrix lyrata）中 Hg、Cu、Cr、Cd、Pb 和 Zn 的存在情况。贻贝全组织中的金属水平为 Zn＞Cu＞Cr＞Pb＞Cd＞Hg。在 EJC 沿线的许多地方，贻贝组织中的 Cr、Cd 和 Pb 水平超过了食用的可耐受极限和暂定每周可接受摄入量（PTWI）。在几个地方，Cr、Cd 和 Pb 的目标危害系数（THQ）大于 1，表明这些金属可能对消费者（特别是非致癌影响）有害。食用该地区的贻贝可能对人类健康有害。此外，Cr 和 Cd 的靶致癌风险（TCR）值在几个地方大于 10，这意味着 Cr 和 Cd 可能会导致人们在一生中接触到的致癌物质。
