【摘要】 首次研究了大亚湾大气降尘及其降尘中８种污染物质的入海量。结果表明，大亚湾海区大气降尘入海量为４４６４ｔ·ａ－１，降尘中污染物质入海量为８４．５６ｔ·ａ－１。降尘量的大小与陆域距离远近有关，并具有季节性变化。大气降尘中污染物质含量的多寡与陆地周围工矿企业污染源有密切关系。研究表明，大亚湾海区降尘量较少，大气中污染物质含量低，大气污染物的降落对该海区水体环境影响不大。更多还原

【Abstract】 The article discussed the quantity of dustfall and its pollutants into the sea along Daya Bay. The quantities of dustfall and its pollutants into the sea are 4464t·a-1 and 84. 56t·a-1 respectively. The quantity of dustfall is related to the distance from land and changes with the seasons. The quantity of pollutants in dust fall has close connection with the number of polluting sources such as factories and enterprises.The research showed that Daya Bay is characteristic of small dustfall, low content of pollutants in dust fall and there is little impact of its pollutants on seawater.更多还原
