Effect of Heavy Metals on Brownfield Quality in Different Industries

Abstract:

With the rapid development of urbanization and industrialization in Chongqing, effect of heavy metals on brownfield has been paid more and more attention. 8 brownfields in steel industry, 15 brownfields in chemical industry, 18 brownfields in machining industry and 7 brownfields in pharmaceutical industry were selected as research objects, and eight heavy metals including mercury (Hg), lead (Pb), arsenic (Ar), cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni) and zinc (Zn) in soil were analyzed. Single factor pollution index (SFPI) and integral pollution index (IPI) was used to assess the pollution degree of these sites. The comprehensive results showed that the brownfields in the 4 studied industries had been affected by the heavy metals which produced in industrial activities. Machining industry had the greatest impact on the brownfield in Chongqing, also, the effect of chemical industry and steel industry to the soil were tremendous. Only pharmaceutical industry had little influence on the soil environment.
