Evaluation of Toxicity of Pig Slurry Using Larvae and Embryo of Zebrafish
Biogas slurry becomes a serious pollution problem when anaerobic digestion is widely applied to pig manure treatment for energy recovery.To evaluate environmental risk ofbiogas slurry, larvae and embryonic tests ofzebrafish (Danio rerio)were used to detect the acute toxicity of intake and effluent which was treated by a membrane bioreactor (MBR) of pig biogas slurry.Slurry displayed strong toxicity to both larvae and embryo, while the LC50oflarvaewas only 1.948%, and embryonic development was inhibited at 1%.Slurry toxicity still maintained at a high level although slurry had been treated by a MBR, with the LC50 of larvae of 75.23% and a little effect on the development of embryo.Apparently, larvae were more sensitive than embryo to pig slurry.
