Evaluation of Toxification in Acid and Alkalescent Industry Liquid Wastes from Paper Mill Using C. elegans
利用模式动物线虫追踪造纸厂废水中酸碱类毒物的研究

In the current work, model organism C. elegans was introduced into the Toxicity Identification Evaluation (TIE) procedure to determine the toxification of acid and alkalescent industry liquid wastes from paper mill via analyzing the life span, days corresponding to 50% lethal, reproductive rate, reproductive capacity and locomotion behaviors in worms. Our data indicate that the toxic influence order of different samples on life span was: 2nd >4th >1st>3rd, the toxic influence order of different samples on generation time was: 2nd>1st>3rd?4th, the toxic influence order of different samples on brood size and head thrashes was similar: 1st?2nd>3rd?4th, the toxic influence order of different samples on body bends was: 1st?2nd>3rd>4th, and the 2nd sample always had more significantly toxic effects on different phenotypes. Thus, the toxicity of acid industry liquid waste from the paper mill relatively had the most severe multiple effects, whereas the toxicity of alkalescent industry liquid and grain-like wastes exhibited only limited effects. Our work here effectively evaluate the toxification of acid and alkalescent industry liquid wastes from paper mill.
