摘要 硒是生命活动中的重要元素,世界卫生组织(WHO)1973年确认硒是人类生命必须14种微量元素中的第一线微量元素。硒的营养与中毒的界限是所有元素中最小的一个,若不足,则生物效应为"存活,缺乏",若过量,则"毒性,致死"。为了有效提高电解锰生产过程中的电流效率,国内企业广泛使用二氧化硒(SeO2)作为添加剂,导致操作工人长期暴露在硒污染作业环境中,同时锰渣中挟带大量的硒污染物进入到外环境中,存在着严重而明显的环境和生态隐患。因此,研究分析电解锰行业硒污染及其控制技术具有其必要性及重要性。 硒是生命活动中的重要元素,世界卫生组织(WHO)1973年确认硒是人类生命必须14种微量元素中的第一线微量元素。硒的营养与中毒的界限是所有元素中最小的一个,若不足,则生物效应为"存活,缺乏",若过量,则"毒性,致死"。为了有效提高电解锰生产过程中的电流效率,国内企业广泛使用二氧化硒(SeO2)作为添加剂,导致操作工人长期暴露在硒污染作业环境中,同时锰渣中挟带大量的硒污染物进入到外环境中,存在着严重而明显的环境和生态隐患。因此,研究分析电解锰行业硒污染及其控制技术具有其必要性及重要性。
