With the intensification of industrial and agricultural activities around the world,the pollutants discharged by human beings into water bodies have increased,which has seriously affected the physical and chemical properties and ecological functions of water bodies.Among them,heavy metals have the characteristics of long-term,concealment,non-degradable and bio-enrichment,which will do harm to human health and ecological environment after polluting water bodies and become a rapidly growing environmental problem.The distribution characteristics,risk assessment and source analysis of heavy metals in water have become the research focus of scholars at home and abroad.Focusing on the heavy metal pollution in water,this study summarized the pollution status at home and abroad,the migration and transformation process of heavy metals,the commonly used treatment techniques and evaluation methods,and the source analysis methods of heavy metals,in order to provide reference for the treatment of heavy metal pollution in water.
