摘要

采矿活动造成的重金属污染对食用来自受矿山影响环境的软体动物和甲壳类动物的人构成健康风险。其中一个例子是塔夫脱河,它接收来自菲律宾萨马岛Bagacay矿山的排水和沉积物。为了评估HM在软体动物和甲壳类动物中的积累情况及其对人类的风险,对从河流不同断面采集的代表性标本进行了综合分析。“bebe”(Batissa violacea Lamarck)果肉中Cu (97.67 mg kg-1)、Ni (29.30 mg kg-1)、Pb (0.59 mg kg-1)和Sr (14.67 mg kg-1)的含量显著高于“tangili”(望子)、“tuway”(望子)和“sihi”(Nerita albicilla Linn.);在甲壳类动物中,泥蟹(Scylla serrata)肉中砷(17.67 mg kg-1)、铜(118.67 mg kg-1)、镍(25.79 mg kg-1)、铷(31.33 mg kg-1)、锶(60.67 mg kg-1)和锌(331.00 mg kg-1)的含量高于罗氏沼虾(Macrobrachium rosenbergii)。对长尾贝类、白背贝类和紫背贝类的摄入可能导致砷的估计每日摄入量(EDI)大于砷的临时耐受日摄入量(PTDI) [2.03-4.48 μg kg-1体重(BW) d-1],而所有软体动物的铬的EDI可能在124.59-136.23 48 μg kg-1体重(BW) d-1之间。这可能随后导致成人的高目标危险商数(THQ)、高危险指数(HI)和高目标癌症风险(TCR)。在甲壳类动物中,S. serrata的消耗量超过了As的PTDI指数。罗氏螺旋藻和罗氏螺旋藻的Cr含量均超过PTDI的20 ~ 21倍,其健康风险值分别为22.36和28.57 48 μg kg-1 d-1。总的来说,目前的结果表明,人类食用塔夫脱河软体动物和甲壳类动物可能会无意中导致砷和铬摄入量增加,从而对人类健康产生负面影响。

Heavy Metal Concentrations in Mollusks and Crustaceans Harvested from Eastern Samar’s Taft River in the Philippine and the Health Risks Posed to Consumers
Heavy metal (HM) contamination from mining activities poses a health risk to humans who consume mollusks and crustaceans from mine-affected environments. One such example is the Taft River, which receives drainage water and sediments from the Bagacay mines in Samar, Philippines. To assess the accumulation of HM in mollusks and crustaceans and the associated risks to the humans, a comprehensive analysis was conducted on representative specimens, which were gathered from different sections of the river. The concentrations of Cu (97.67 mg kg–1), Ni (29.30 mg kg–1), Pb (0.59 mg kg–1), and Sr (14.67 mg kg–1) in the flesh of “bebe” (Batissa violacea Lamarck) were significantly higher than those in “tangili” (Telescopium telescopium Linn.), “tuway” (Mercenaria mercenaria Linn.), and “sihi” (Nerita albicilla Linn.); whereas for crustaceans, the flesh of mud crabs (Scylla serrata) contained higher concentrations of As (17.67 mg kg–1), Cu (118.67 mg kg–1), Ni (25.79 mg kg–1), Rb (31.33 mg kg–1), Sr (60.67 mg kg–1), and Zn (331.00 mg kg–1) compared with giant freshwater prawns (Macrobrachium rosenbergii). The consumption of T. telescompium, N. albicilla, and B. violacea may result in an estimated daily intake (EDI) that is greater than the provisional tolerable daily intake (PTDI) for As [2.03–4.48 μg kg–1 body weight (BW) d–1], while all mollusks may have an EDI for Cr of between 124.59–136.23 48 μg kg–1 BW d–1. This may subsequently lead to a high target hazard quotient (THQ), high hazard index (HI), and high target cancer risk (TCR) for adults. With respect to crustaceans, the consumption of S. serrata exceeds the PTDI index for As. Both S. serrata and M. rosenbergii exceed the PTDI for Cr by 20–21 times, as well as the elevated health risk values of 22.36 and 28.57 48 μg kg–1 d–1 for M. rosenbergii and S. serrata, respectively. Overall, current results indicate that human consumption of the Taft River mollusks and crustaceans may inadvertently lead to an increased intake of As and Cr that could negatively impact human health.
