Bioensaios para avaliação da toxicidade aguda, reprodução e ganho de biomassa de minhocas (Eisenia fetida) ambientadas em lodo de esgoto doméstico
Abstract
Este trabalho tem por objetivo avaliar os efeitos que o lodo de esgoto doméstico produz na toxicidade, reprodução e ganho de biomassa em minhocas Eisenia fetida. Os resultados obtidos demonstraram que nem o LED nem tampouco o LED diluído em solo apresentam toxicidade aguda para as minhocas sendo que estas tiveram um ganho de biomassa durante os primeiros 14 dias de exposição ao resíduo; no entanto após este período, os organismos tenderam a perder massa.Downloads
