Abstract:
Toxicity of effluents after treatment in an anaerobic fermentation system for hydrogen production is evaluated with three biotests: The zebrafish Danio rerio embryo test, the Thamnotoxkit F and the Daphtoxkit F(TM) magna. Samples were classified from "very" to "extremely toxic". Average toxicity values for zebrafish were 1.55% (24 h) and 0.75% (48 h), for Thamnocephalus 0.69% (24 h) and for Daphnia 2.51% (24 h) and 1.82% (48 h). Statistical analysis between physicochemical parameters and LC(50) values revealed that PO(4)(-3), SO(4)(-2), NH(3)N and NO(3)(-) have the major contribution to toxicity. Based on results, this treatment is considered an environmentally ineffective way of managing the specific wastes.
