Abstract
Ambient air concentrations of asbestos fibers were measured during the period June 20 to August 12, 1980, at three locations; Danville, Asbestos, and Wottenville in the eastern townships of Quebec. Measurements were done with low-volume samplers and measurement periods extended from 3 to 13 days. Fiber counts were done by means of electron microscopy. Results indicate that overall fiber concentrations are related to atmospheric stability and to the direction of the prevailing wind with respect to the source of emission.
摘要
1980年6月20日至8月12日期间，在魁北克东部乡镇的三个地点（丹维尔、石棉镇和沃滕维尔）测量了环境空气中石棉纤维的浓度。测量使用低流量采样器，测量周期从3天延长至13天。通过电子显微镜进行纤维计数。结果表明，总体纤维浓度与大气稳定性以及盛行风相对于排放源的方向有关。
