摘要
潜在有毒元素(PTEs)在环境中自然存在,但人类活动促使其高度集中,对环境和人类健康造成危害。通过实验室分析(美国公共卫生协会标准)、指标和统计技术,对邦尼河沿岸小溪(菲比利溪和伊沃亚马溪)中的潜在有毒元素(铁 (Fe)、镍 (Ni)、镉 (Cd)、硒 (Se)、锌 (Zn)、铅 (Pb)、铬 (Cr) 和铜 (Cu))的生态毒理学状况、来源分配和健康风险评估进行了研究。两条溪流的地表水和沉积物中的 PTEs 浓度都超过了世界卫生组织的允许限值,地表水的趋势是 Cr > Pb > Fe > Ni > Cd > Zn > Cu >;硒,而伊沃亚马溪的沉积物则呈以下趋势:Fe > Pb > Ni > Cr > Zn > Cd > Cu > Se。溪流沉积物的污染因子(CF)显示为低 CF(锌和铜)、中等 CF(镍、铅和铬)和极高 CF(铁和镉),而风险指数状况则从低风险(镍、锌、铅、铬和铜)、中等风险(铁)到显著高风险(镉)不等。人体健康风险显示,溪流环境介质中的镍、铅、铬和镉对儿童的潜在非致癌影响(HI > 1)为 1.64 和 2.03,对儿童的总致癌风险(TCR)为高致癌风险(TCR > 1 × 10-4)。溪流趋势和状况的相似性表明,这两种环境都受到类似人为活动的影响。
Ecotoxicological status, source apportionment and human health risk assessment of potential toxic element in surface water and sediments of creeks along Bonny River, Nigeria
Potentially toxic elements (PTEs) are naturally available in the environment; however, anthropogenic activities encourage their high concentration, posing environmental and human health risks. The ecotoxicological status, source apportionment and health risk assessment of PTEs (Iron (Fe), Nickel (Ni), Cadmium (Cd), Selenium (Se), Zinc (Zn), Lead (Pb), Chromium (Cr) and Copper (Cu)) in creeks (Fibiri and Iwoama) along Bonny River were examined through laboratory analysis (American Public Health Association standard), indicators and statistical techniques. The PTEs concentration of surface water and sediment for both creeks exceeded the WHO allowable limit, and the surface water trended as Cr > Pb > Fe > Ni > Cd > Zn > Cu > Se for Fibiri creeks, Fe > Cr > Pb > Ni > Cd > Zn > Cu > Se for Iwoama creek while the sediment trended as Fe > Pb > Ni > Cr > Zn > Cd > Cu > Se for both creeks. The contamination factor (CF) of the creek’s sediment showed low CF (Zn and Cu), moderate CF (Ni, Pb and Cr) and very high CF (Fe and Cd), while risk index status ranged from low risk (Ni, Zn, Pb, Cr and Cu), moderate risk (Fe) and significantly high risk (Cd). The human health risk revealed that children could be exposed to potential non-carcinogenic effect (HI > 1) with Zn (1.64 and 2.03), and the Total Carcinogenic Risk (TCR) for children indicated high carcinogenic risk (TCR > 1 × 10−4) for Ni, Pb, Cr and Cd of the creeks’ environmental mediums. The similarity in the trend and status of the creeks suggested that both environments are exposed to similar anthropogenic activities impact.
