对斯里兰卡的1,304个井水样本进行了分析，以评估饮用水对人体健康的潜在风险。20%的威尔斯井氟浓度大于1.0 mg/L，特别是在CKDu流行的干旱地区。氟化物是该地区CKDu的疑似原因。在农业活动密集的地区，2.2%的威尔斯水井的硝酸盐浓度超过50毫克/升。在0.9%的威尔斯井中发现砷浓度超过10 mg/L。受污染的井水可能对人类健康构成潜在风险。
A total of 1,304 well water samples from Sri Lanka were analyzed to assess the potential risk of drinking water to human health. Fluoride concentration of more than 1.0 mg/L was found in 20% of the wells, especially in the dry zone where CKDu is prevalent. Fluoride is a suspected cause of CKDu in the region. Nitrate concentrations of more than 50 mg/L were recorded in 2.2% of the wells in areas with intense agricultural activity. Arsenic concentrations of more than 10 mg/L were found in 0.9% of the wells. Contaminated well water could pose a potential risk to human health.
