This is one of few studies dealing with the potential impact of total carbohydrates (TCHO), and some inorganic pollutants (F, B, As, V, Se) on human health. Additionally, the latter pollutants toxicological and ecological effects on the Egyptian Mediterranean Coast, especially, the Nile Delta region, were investigated. Both F (0.18 ± 0.09 mg/g) and As (2.47 ± 5.39 μg/g) were of lower concentrations compared to previous reports. Values of all ecological and ecotoxicity indices, particularly, the risk quotient (RQ), showed that arsenic had the most adverse biological effects on three trophic levels (algae, invertebrates, and fish). Children and adults non-carcinogenic hazard index (HI) values were <1, revealing that sediments in the studied area would pose no risk to humans. However, arsenic carcinogenic risk (CR) values exceeded the maximum permissible limits, implying risk to children and adults. These findings could anticipate toxic impacts of polluted effluents on the Nile Delta region.

埃及地中海沿岸尼罗河三角洲地区总碳水化合物和一些无机污染物的生态毒理学、生态和人类健康风险


这是少数涉及总碳水化合物 (TCHO) 和一些无机污染物（F、B、As、V、Se）对人类健康潜在影响的研究之一。此外，还调查了后者污染物对埃及地中海沿岸，特别是尼罗河三角洲地区的毒理学和生态影响。与之前的报告相比，F (0.18 ± 0.09 mg/g) 和 As (2.47 ± 5.39 μg/g) 的浓度均较低。所有生态和生态毒性指数的值，特别是风险商（RQ），表明砷对三个营养级（藻类、无脊椎动物和鱼类）具有最不利的生物影响。儿童和成人的非致癌危害指数（HI）值为<1，表明研究区域的沉积物不会对人类构成风险。然而，砷的致癌风险（CR）值超过了最大允许限值，这意味着对儿童和成人存在风险。这些发现可以预测受污染的废水对尼罗河三角洲地区的毒性影响。
