微塑料污染已成为全球威胁,和水,作为污染物的主要“汇”,代表了人类暴露的重要来源。本研究旨在评估BirninKebbi钻孔水的安全性,尼日利亚,特别是关于微塑料污染。从选定区域的钻孔中收集水样,包括BayanKara,Malali,RafinAtiku,AlieroQuarters,GwadanGaji,FUBK起飞地点,Kalgo市场,还有Tarasa.使用玻璃纤维滤纸通过过滤从水样中提取微塑料,并随后进行光谱学和显微镜检查以确定浓度,形状,和聚合物类型。还计算了与微塑料相关的健康风险。结果表明,来自Tarasa的样品显示出最高的微塑料浓度(96.967颗粒/L),其次是BayanKara(92.70粒子/L),拉芬·阿提库(92.33粒子/升),GwadanGwaji(92.30颗粒/升),FUBK起飞现场(91.07颗粒/升),AlieroQuarters(90.43粒子/L),卡尔戈市场(88.00颗粒/升),和Malali(86.40颗粒/升)。最主要的形状是纤维(73%),其次是碎片(16%),泡沫(6%),和长丝(5%)。聚乙烯和聚酰胺,按照这个顺序,是最主要的聚合物,而聚苯乙烯是最不常见的。大多数风险评分被归类为III。从结果可以推断,钻孔水中的微塑料污染对城市的健康构成了危害。建议研究区域的钻孔水消费者在饮用前处理水,以减轻潜在的健康风险。
Microplastic pollution has become a global menace, and water, being a major \"sink\" for pollutants, represents a significant source of human exposure. This study aimed to assess the safety of borehole water in Birnin Kebbi, Nigeria, specifically concerning microplastic pollution. Water samples were collected from boreholes in selected areas, including Bayan Kara, Malali, Rafin Atiku, Aliero Quarters, GwadanGaji, FUBK Takeoff Site, Kalgo Market, and Tarasa. Microplastics were extracted from the water samples through filtration using glass fiber filter papers, and were subsequently subjected to spectroscopy and microscopy to determine concentrations, shapes, and polymer types. Health risks associated with the microplastics were also calculated. The results revealed that the samples from Tarasa exhibited the highest concentrations of microplastics (96.967 particles/L), followed by Bayan Kara (92.70 particles/L), Rafin Atiku (92.33 particles/L), GwadanGwaji (92.30 particles/L), FUBK Takeoff Site (91.07 particles/L), Aliero Quarters (90.43 particles/L), Kalgo Market (88.00 particles/L), and Malali (86.40 particles/L). The most dominant shape was
fibers (73 %), followed by fragments (16 %), foams (6 %), and filaments (5 %). Polyethylene and polyamide, in that order, were the most dominant polymers, while polystyrene was the least common. The majority of risk scores were classified as III. It can be inferred from the results that microplastic pollution in borehole water poses a health hazard in the city. Consumers of borehole water in the studied areas are advised to treat the water before consumption to mitigate potential health risks.
