摘要

汞(Hg)是一种全球关注的重金属,因为它在环境中的持久性及其在生态系统中的生物积累和生物放大能力。尽管有证据表明铜带省存在广泛的环境污染,但很少有研究调查赞比亚基特韦地区Kafue河及其支流的汞污染。采用电感耦合等离子体质谱仪(ICP-MS)测定矿区和非矿区土壤、沉积物和罗非鱼中的总汞浓度。矿区与非矿区土壤样品(Mean (mining) = 1.066, Mean(非mining) = 0.041, p≤0.05)和沉积物样品(Mean (mining) = 1.304, Mean(非mining) = 0.034, p≤0.05)的种群均值存在显著差异。在开采区和非开采区之间,鱼类样本的种群均值(Mean (mining) = 0.015, Mean (non-mining) = 0.007, p≤0.05)差异也有统计学意义。矿区土壤和沉积物中的汞含量分别高于美国环境保护署(USEPA)的参考值0.3 mg/kg和0.2 mg/kg。Kitwe矿区鱼体大小(长度)与汞积累呈弱正相关(r = 0.232, P = 0.1166)。汞积累量与鱼体长度的相关性无统计学意义(P < 0.05)。食用矿区鱼类的EDI分别低于USEPA和WHO/FAO的最大可耐受日摄入量0.1µg/kg/day和0.23µg/kg。的公司

Assessment of total mercury (Hg) in soil, sediment, and tilapia fish (Oreochromis niloticus) and health risk assessment among residents of Kitwe mining area, Zambia.

Mercury (Hg) is a heavy metal of global concern because of its persistence in the environment and its ability to bioaccumulate and biomagnify in ecosystems. Despite evidence of extensive environmental pollution in the Copperbelt Province, few studies have investigated Hg contamination in the Kafue River and its tributaries in Kitwe District, Zambia. Total Hg concentrations were determined in soil, sediments, and tilapia by inductively coupled plasma mass spectrometer (ICP-MS) from the mining areas and non-mining areas. There were significant differences in the population means for soil samples (Mean (mining) = 1.066, Mean (non-mining) = 0.041, p 0.05 ) and sediment samples (Mean (mining) = 1.304, Mean (non-mining) = 0.034), p 0.05 ) between mining and non-mining areas. There were also statistically significant differences in the population means for fish samples (Mean (mining) = 0.015, Mean (non-mining) = 0.007, p 0.05 ) between mining and non-mining areas. The levels of Hg in the soil and sediments from the mining area were higher than the United States Environmental Protection Agency (USEPA) reference values of 0.3 mg/kg and 0.2 mg/kg, respectively. There was a weak positive correlation between the size of the fish (length) and Hg accumulation in the Kitwe mining area (r = 0.232, P = 0.1166). The observed correlation between Hg accumulation and length of fish was not statistically significant (P > 0.05). The EDI from the consumption of fish from the mining area was below the USEPA and WHO/FAO maximum tolerable daily intake of 0.1 µg/kg/day and 0.23 µg/kg, respectively. The THQ < 1 was also reported in the current study, suggesting that the exposure level may not cause adverse health effects during a lifetime in the human population. Although the EDI and THQ < 1 in the current study were below the USEPA and WHO/FAO maximum tolerable limit, the presence of Hg in fish in this area must be monitored due to its ability to bioaccumulate in large and predatory fish. The lower EDI value reported in the current study might be attributed to the smaller size of the tilapia fish specimens, resulting in low bioaccumulation of Hg. Since the Hg levels in sediments were above the USEPA limit, we recommend further studies on the bioavailability of Hg in humans and other fish species in the region, particularly carnivorous fish, due to Hg biomagnification to offer a clearer perspective on the environmental and health impacts.
