Abstract: Differentiated environmental management can be achieved by identifying the environmental risk levels of brownfield sites. This can increase the efficiency of land development under the premise of residential environment safety and mitigate the shortage of land resources in the city. By analyzing the soil contamination risk, levels, types, distribution characteristics of 93 brownfield sites in a typical city of Guangdong-Hong Kong-Macao Greater Bay Area during 2013-2018, the influences of industrial types on soil contamination risk and characteristics were discussed. The results show that more than 85% of the brownfield sites were from metal surface/thermal treatment, chemical raw materials and chemical manufacturing, and metal melting/pressing industries. The contaminated soil volume per square meter of these three industrial types of brownfield sites exceeds 0.32 m³ and the pollution load index exceeds 0.5. Thus, these three industrial types are identified as high contamination risk types. The brownfield sites of metal surface/thermal treatment industries are mainly contaminated by inorganic pollutants, and the main contaminants are heavy metals. On the contrary, organic pollutants such as BTEX, polycyclic aromatic hydrocarbons (PAHs) and petroleum hydrocarbons are mainly in the brownfield sites of chemical raw materials and chemical manufacturing industries. The coexistence of inorganic and organic contaminants mainly occurs in the brownfield sites of metal melting/pressing industry, and the main contaminants are PAHs, lead, arsenic, nickel and zinc. The industries of electrical machinery and equipment manufacturing, handling and warehousing, commercial service, textile, cultural/athletic/recreation products manufacturing, plastic product, agriculture, and livestock are identified as low contamination risk industrial types. The brownfield sites in this city are mainly complex pollution, and the main contaminants are heavy metals, cyanide, fluoride, and organic compounds. The frequencies of occurrence of arsenic and PAHs are approximately 50.0%, which were the highest among all the contaminants. Thus, the soil contamination risk, levels, types, and distribution characteristics of the brownfield sites are closely related to their regional characteristics and historical land-use patterns. Therefore, it is of great significance for environmental protection authority to differentiate the investigation and supervision of closed brownfield sites according to the industrial types.
