Abstract Based on the data collected from the British Geological Survey, European Pollutant Release and Transfer Register, China Statistical Yearbook on Environment, and Annual Statistic Report on Environment in China, the variations of metal production, regional and industrial distributions of heavy metals discharge from industrial wastewater were compared for China and European Union. Although the metal production increased quickly from 1993 to 2014, the total discharge of heavy metals in wastewaters decreased. This is ascribed to the change in production modes, technology innovation, and improvement of wastewater discharge standard. The regional and industry distributions of heavy metals in wastewaters were different for different heavy metals. Whereas, the regional and industrial distributions of heavy metal discharges from industrial wastewaters of European Union change insignificantly from 2007 to 2013. Moreover, the European Union’s experience in policy formulation and supervision will help China learn from it. Key words industrial wastewater; heavy metal; region distribution; industry distribution; China; European Union
