【摘要】 <正> 磺化粗菲(以下称S-808)是我国科技人员自己研制的一种胶磷矿浮选剂,经有关部门鉴定认为选矿效果好、毒性低。但S-808作为选矿剂,使用量和废水量都相当大,且随同选矿尾水排入矿区附近的江、河、湖泊,波及面很广,若废水处理不当或不加限制的任意排放,即使毒性虽小,亦有可能污染水源,影响水生物和农作物生长,更多还原

【Abstract】 Crude sulfonated phenanthrene is a kind of floatation agent used for phosphorus ore dressing.In order to prevent the tail water of ore selection polluting the surface water,the maximun permissible concentration of crude sulfonated phenanthrene in surface water should be established.Comprehensive toxicological studies,including dominant lethal mutation assay and teratogenic test,were conducted.According to the results of a series of experiments,the recommended maximum permissible concentration of crude sulfonated phenanthrene (S-808) in surface water is 10mg per liter of water.更多还原
