Abstract: With the extending of the livestock and poultry farming,veterinary drugs are widely used to treat diseases or as growth promoters.From 2010 to 2017,the sales of veterinary antibacterial drugs increased from 31 500 to 56 800 t.The irrational application of veterinary drugs,improper handling of wastes in livestock and poultry breeding,and the excretion of unchanged or metabolites of veterinary antibiotics are the main reasons of environmental pollution caused by veterinary drugs.After entering the environment,the migration and transformation of veterinary drugs has caused serious harms,including the emergence of resistant bacteria or antimicrobial-resistant genes,and the exposure of veterinary drugs in plants and animals’ products as well as drinking water,which indirectly affect human health and the ecological toxicity of non-target animals.The paper discussed the processes of environmental exposure,fate and the impacts on the ecological environment of veterinary drugs.Then the importance of environmental risk assessment of veterinary drugs was analyzed.Finally,the potential ways to find measures and solve the environmental exposure risks of veterinary drugs were prospected.This review will help to attract people's attention to environmental risk assessment of veterinary drugs.

Key words: veterinary drugs; ecological environment; exposure assessment; effect assessment
