title: Ecotoxicity bioassays on leachates from poultry manure.
abstract: The main aim of this study was to evaluate the toxicity of different poultry manure landfill leachates, using a well-known toxicity test system (MS3). The bioassay was made using a battery of toxicity tests including acute toxicity with crustacean (Daphnia magna), algae (Chlorella vulgaris) and the in vitro toxicity test with the fish cell line RTG-2. On D. magna was high mortality for zero time and almost 100 % and 70 %-80 % mortality for sawdust and straw poultry manure respectively. No effects on C. vulgaris, was observed after the leachate exposure. None of the parameters considered: protein, EROD activity, β-gal activity and neutral red, showed differences between control test and the leachate collected from exposure to poultry manure.
