title: Hepato-toxic effect of diuron in albino rats.
abstract: Tumour initiating/promoting effect of diuron, a widely used substituted urea herbicide, was studied in rats using liver tumour model. Chronic exposure to diuron at a dose of 250 mg/kg body wt resulted in high mortality and weight loss in treated animals. The animals which received diuron + HCH treatment showed an increase in size and weight of liver as compared to controls. Liver tumours were not observed in any of the treated group whereas some significant histological changes were seen in diuron treated rat liver. Diuron thus has been found to be hepatotoxic albeit neither tumour initiating nor promoting in rat liver tumorigenesis assay system.
