[Heavy Metal Contamination and Migration in Correspondence of an Electroplating Site on the Hilly Lands of the Guangdong-Hong Kong-Macau Greater Bay Area, China].

The Guangdong-Hong Kong-Macau Greater Bay Area presents the highest number of electroplating corporations in China; some of them of very large scale. Electroplating emissions are the cause of widespread heavy metal contamination of both soil and groundwater in the Guangdong-Hong Kong-Macau Greater Bay Area. Hence, the reuse of electroplating sites in this area should be preceded by an analysis of heavy metal characteristics and migration in the soil and groundwater.
