摘要: 通过因子分析和相关回归分析,台湾海峡海域大气中颗粒物中金属的来源特征为:Fe主要来自地壳风化尘土,少量来自污染物.Pb和Cd主要来自污染源,少量Pb来自尘土和海水.Na主要来自海水,但也有少量来自尘土和次生气溶胶.Cu主要来自尘土,部分来自污染物,少量来自海水.比较台湾海峡西部海域来自大气和来自河流的金属通量,大气中的Cu低于河流,Pb高于河流,Cd略高于河流.Abstract: Atmospheric metals over the western Taiwan Strait were studied and their sources identified. Al and Fe are mainly from crustal soil. A little amount of Fe is from pollution, Pb and Cd are from pollution sources. A little amount oI Pb is from crustal soil and recycled sea spray. Na is mostly from seawater and a little amount of Na from crustal soil or secondary aerosol particles. Cu is mainly from crustal soil partly from pollutants, and a little amount from recycled sea spray. Comparing the total inputs of the atmospheric deposition of the metals to the Taiwan Strait waters with the inputs from rivers shows that the input of Cu from the atmosphere is lower than that from the rivers, and the input of Pb is higher than that from the rivers; the input of Cd is a little higher than that from the rivers.
