摘　　要：Cl-、SO24-和NO3-是滨海大气中的主要水溶性阴离子.2005年6月～2006年5月期间,对连云港田湾核电站滨海大气中主要水溶性阴离子Cl-、SO24-和NO3-进行了监测.研究表明,田湾核电站大气中Cl-、SO24-和NO3-的年均值分别为(33.12±53.63)、(53.34±30.34)和(8.34±4.47)μg·m-3;季节变化分析表明,Cl-、SO24-浓度在夏季高、冬季低,NO3-浓度在秋冬季高、夏春季低.气象因素分析表明,风向、风速、气温、相对湿度等对大气阴离子浓度有一定影响.本研究首次对我国滨海核电大气中主要腐蚀性阴离子进行了同时监测,为防止海洋大气腐蚀,保证我国核电工业安全经济运行提供了依据.Three major water-soluble anions（Cl-,SO24-and NO 3-） in the atmosphere of the Tianwan nuclear power station in Lianyungang were determined by ion chromatography from June 2005 to May 2006.The results showed that the annual average concentration of Cl-,SO42-and NO 3-in the atmosphere of Tianwan nuclear power station was（33.12 ± 53.63） μg·m-3,（53.34 ± 30.34）μg·m-3 and（8.34 ± 4.47）μg·m-3,respectively.The concentrations of the three water-soluble anions showed evident trend of seasonal variation.The concentrations of Cl-,SO42-reached the highest level in summer and the lowest level in winter,while the concentration of NO 3-in autumn and winter was higher than those in summer and spring.Meteorological parameters such as wind direction,wind speed,temperature and relative humidity were studied and showed definite influence to the anions concentration of the atmosphere.This is the first simultaneous monitoring of corrosive anions in the atmosphere of Chinese coastal nuclear power plant,and it will provide basis for the prevention of marine atmospheric corrosion,which will ensure the safely operating of our nuclear power industry.
