The review of available data on the concentrations of asbestos in U.S. water supplies suggests that the majority of water consumers are not exposed to asbestos concentrations over 1 million fibers/Liter. A few populations, however, may be exposed to concentrations over 1 billion fibers/L. Of the 538 water supplies for which waterborne asbestos data are available, 8% have concentrations of fibers over 10 million fibers/L. The vast majority of asbestos fibers found in U.S. water supplies are under 5 micron in length.
对美国供水系统中石棉浓度现有数据的审查表明,大多数用水者接触到的石棉浓度不超过100万纤维/升。然而,少数人群可能接触到超过10亿纤维/升的浓度。在有水中石棉数据的538个供水系统中,8%的纤维浓度超过1000万纤维/升。在美国供水系统中发现的绝大多数石棉纤维长度小于5微米。
