Phagocytosis by earthworm coelomocytes: A biomarker for immunotoxicity of hazardous waste site soils.

摘要

Several biomarkers (cell viability and phagocytosis) based on earthworm (Lumbricus terrestris) immune cells (coelomocytes), together with whole-worm mortality (LC/LD50's), were used to assess a bioremediation attempt to reduce pentachlorophenol (PCP) toxicity in a former wood processing hazardous waste site (HWS). Prior to assessment, by testing three HWS soil samples (contaminated untreated, fungi treated and a treatment control containing sterile saw dust, the fungi substrate), both biomarkers were evaluated by exposing earthworms to sublethal concentrations of chemicals for which there are comparative data for L. terrestris (Cu
