The Toxicity Of Acetaminophen, Caffeine And Carbendazim In Earthworms (Eisenia Fetida), Matthew M. Bulman
Masters Theses
There has been a need for the assessment of ground water contamination risk on terrestrial organisms. One terrestrial organism, Eisenia fetida, was chosen as a test species and exposed to three common pharmaceutical and/or pesticide related contaminants: acetaminophen (CAS#103-90-2), caffeine (CAS#58-08-2) and carbendazim (CAS#10605-21-7), respectively. Levels of contamination varied from grams per liter to micrograms per liter (ppb) using distilled water as the solvent. Eisenia fetida was examined through a 28 day range/index toxicity test. A Benchmark Dose (BMD) dichotomous probit analysis, using a 95% confidence interval, was calculated for all three contaminants. All three contaminants were found to have …
