Phosphogypsum is a kind of industrial solid waste produced by wet phosphoric acid. Although there is an increase in the utilization rate of phosphogypsum, its consumption is limited. At present, it is still treated through accumulation, which will not only occupy land resources, but also causes serious environmental pollution. This paper reviews the discharge and comprehensive utilization of phosphogypsum in China, and analyzes the environmental impact of phosphogypsum, which is mainly manifested in the storage process: ①The atmospheric influence induced by hydrogen fluoride gas, radionuclides, heavy metal elements adsorbed by nanoparticles and the greenhouse effect; ②The variation of water pH, the abnormality of heavy metal content, the living environment of phytoplankton and the imbalance of Marine phosphorus cycle; ③Influence of soil pH and heavy metal content on soil environment. For the purpose of resource conservation and environmental protection, considering the current situation of comprehensive utilization and treatment of phosphogypsum, the technical innovation of phosphogypsum disposal, the monitoring and evaluation of pollutant discharge from phosphogypsum storage sites, and the study of environmental toxicological effects of phosphogypsum storage sites should be the focus of future research.
