摘要
1988～1992年连续采集了黄海西北部的大气降水,分析样品中的氟而得到的80多个数据显示出大气降水中氟的平均浓度低于中国北方主要河流的氟平均浓度。在冬季,氟的浓度较其他季节高,这可能和降雨量减少以及人为因素等密切相关。目前还难以估算出人为因素对氟在降水中化学行为的影响程度,但数据显示出人口密集地区降水中氟的浓度明显高于人口稀疏的自然地带。
Samples of wet deposition were collected from the north Huanghai Sea in 1988- 1992. With about eighty data, we found that the average concentration of fluoride in wet deposition is lower compared with those from the major rivers in North China. In winter the concentration of fluoride is quite higher than that in other seasons. It may be for the reason of little precipation and anthropocentric activities. At present it is difficult to estimate the impact of anthropocentric activities upon the chemical character of fluoride in rain/ snow, but samples from urban areas show higher fluoride concentrations compared with remote rigions in this study.
