High-level exposure to lithium, boron, cesium, and arsenic via drinking water in the Andes of northern Argentina.

摘要: Elevated concentrations of arsenic in drinking water are common worldwide, however, little is known about the presence other potentially toxic elements. We analyzed 31 different elements collected San Antonio de los Cobres and five surrounding Andean villages Argentina, urine inhabitants, using ICP-MS. Besides confirmation elevated (up to 210 mug/L), we found remarkably high lithium (highest 1000 cesium (320 rubidium (47 boron (5950 mug/L). Similarly arsenic, lithium, cesium, were studied women (N = 198): village median values ranged from 26 266 mug/L 340 4550 34 531 2980 16 560 boron. There an apparent risk effects long-term exposure several elements, studies on associations with adverse human health warranted, particularly considering combined, life-long exposure. Because observed wide range concentrations, all sources used for should be screened a large number elements; obviously, this applies globally. (Less)
