| 摘 要： | 监测分析了2000年--12月份在不同气象条件下新加坡降雨中的痕量金属质量浓度水平．随着排放强度和气象条件的改变，痕量金属的月平均质量浓度也发生相应变化．通过与世界其他地区监测值的对比和数据分析，可以确定新加坡降雨中的痕量金属不仅有自然尘土的影响，也受到人为排放源的强烈影响．计算结果表明，在新加坡的大气环境中，降雨酸度与降雨对包含不溶痕量佥属的细小颗粒物的截获率有正相关关系。

| Abstract: | The mass concentrations of trace metals in rainwater in Singapore under a variety of meteorological conditions from January to December 2000 have been monitored in this study. It is found that the mean mass concentrations varied from month to month due to changes in emission intensity and meteorological conditions. The origins of the trace metals in rainwater in Singapore come not only from natural soil/dust but also from anthropogenic sources significantly through comparison with the data from other sites in the world. Some calculation show that fine particulates with insoluble trace metal are scavenged more efficiently in the Singapore atmosphere by more acidic rainwater. |
