| 摘 要： | 气态元素汞(gaseous elemental mercury,GEM)是普遍存在于大气中的对生物体有害的重金属元素其化学性质稳定,在大气中停留时间长,可随气团长距离输送属于全球性污染物.本研究于2017年夏秋季对宁波市大气GEM、常规污染物和气象参数进行综合观测,研究沿海地区GEM受人为源和自然源共同作用下的迁移转化规律及潜在源贡献来源.结果表明:①观测期间大气GEM的平均质量浓度为(2.32±0.90) ng·m-3,变化范围为0.97～10.95 ng·m-3,且夏季低于秋季.②GEM、O3和GOM在夏季、秋季、晴天和阴雨天的日内浓度变化表明,高浓度的O3和强烈的光照可加速GEM发生光化学反应,GEM在晴天的光化学氧化强度高于阴雨天.③相关性分析表明,GEM与PM2.5(R=0.65,P<0.01)、PM10(R=0.47,P<0.01)、NO2(R=0.46,P<0.01)和CO(R=0.57,P<0....
