摘要

本研究检测了巴基斯坦米安瓦利地区印度河中六种常见鱼类(鲤鱼、鲫鱼、瓦拉古阿图鱼、鳙鱼、鳢鱼和鲈鱼)肌肉组织中七种重金属(铅、铜、锌、铬、镉、镍和锰)的浓度。样本在季风前和季风后两个季节采集,以评估这些重金属对人类健康的潜在风险。采用原子吸收光谱分析法测量了重金属含量。结果显示,鱼类样本中的重金属浓度(毫克/千克)各不相同,铅为 10.17-2.06,铜为 41.83-12.54,锌为 417.04-41.93,铬为 2.06-0.46,镉为 0.86-0.08,镍为 4.33-1.43,锰为 50.16-8.74。值得注意的是,季风前季节的金属浓度普遍较高,所有鱼类肌肉组织中的铅浓度均超过标准限值。方差分析显示,不同鱼类物种的重金属浓度存在显著差异。虽然目前的食用率不会对健康造成重大风险,但持续监测鱼类及其环境来源中的重金属浓度对于确保消费者安全和可持续的水生生态系统至关重要。

Heavy metal pollution in commonly consumed fish species: seasonal variations and health risks.

This study examined the concentrations of seven heavy metals (Pb, Cu, Zn, Cr, Cd, Ni, and Mn) in the muscle tissue of six commonly consumed fish species (Cyprinus carpio, Labeo rohita, Wallagu attu, Hypophthalmicthys molitrix, Channa punctuate, and Puntius sophore) from the River Indus in the Mianwali district Pakistan. Samples were collected during both pre-monsoon and post-monsoon seasons to assess the potential human health risks associated with these heavy metals. The levels of metals were measured using atomic absorption spectroscopic analysis. The results showed varying concentrations of heavy metals in the fish samples (mg/kg), ranging from 10.17-2.06 for Pb, 41.83-12.54 for Cu, 417.04-41.93 for Zn, 2.06-0.46 for Cr, 0.86-0.08 for Cd, 4.33-1.43 for Ni, and 50.16-8.74 for Mn. Notably, metal concentrations were generally higher during the pre-monsoon season, with Pb consistently exceeding standard limits in the muscle tissue of all fish species. ANOVA analysis revealed significant variations in heavy metal concentrations among different fish species. While the current consumption rate poses no significant health risks, ongoing monitoring of heavy metal concentrations in fish and their environmental sources is crucial to ensure consumer safety and sustainable aquatic ecosystems.
