①堆放、填埋---占用耕地，污染水②焚烧—污染大气
③堆肥、发电、分类、回收利用---环境效益好
4、影响大气污染扩散和自净的因素：⑴污染物排放量大小：若排放量小，则易扩散
⑵气象条件：风速、风向、气温、湿度、云况、辐射等
⑶地形：盆地、河谷地形，不利于污染物扩散
5、可吸入颗粒物污染 ［ 注：逆温天气―――大气层稳定――扩散慢］
北方城市大气以可吸入颗粒物为主：
原因： ①自然：北方降水少植被覆盖率低、荒漠、裸地多，天气干燥多大风
②人为：燃煤、机动车尾气、建筑工地
治理措施： ①能源：减少煤使用
②限制排放污染(工业、汽车、建筑工地)
③扩大绿化面积
6、酸雨：污染物：化石燃料――酸性气体（SOX、 NOX）
原因：自然：火山喷发、地震等自然现象放出大量酸性气体
