文摘

Municipal wastewater effluents (MWWE) contain a lot of trace organic pollutants, which will be a threat to environmental health. However, little information is available for the mixed toxicity of MWWE on mammals. In the present study, male mice were exposed to MWWE for 90 days, and then, histopathology and clinical biochemistry determination and transcriptomic and metabolomic profiling were conducted. The results showed that MWWE exposure resulted in injuries in liver and kidney. Combined transcriptomic and metabolomic data demonstrated that MWWE exposure induced perturbations of metabolism, including lipid, nucleotide, amino acid, and energy metabolism. Furthermore, dysregulation of signal transduction processes were also identified based on differentially expressed genes. These results suggested that chronic exposure to MWWE could induce hepatotoxicity and nephrotoxicity in mice and omic approaches are of practical value to evaluate the complex toxicity of MWWE.
