Abstract

Lead levels were generally found to be high in road-side dust samples collected from different sites throughout the Island of Hong Kong during winter 1977-78. Considerable differences in the concentration of lead amongst these sites were detected but such differences bore no direct relationship to the traffic volumes of the sites from which the samples were collected. Different districts within the city varied widely in the mean concentration of lead in their road-side dust samples.

摘要

在1977 - 1978年冬季从香港岛不同地点采集的路边灰尘样本中，通常发现铅含量很高。检测到这些地点之间铅浓度存在显著差异，但这些差异与采集样本地点的交通流量没有直接关系。城市内不同区域路边灰尘样本中的铅平均浓度差异很大。
