Abstract. The soil around a lead-zinc mining area was taken as the research object. The available concentrations of Cd , Pb, As in soil of four regions were investigated. Then geostatistics and multistatistics were applied to analyze the distribution characteristics of available heavy metals. The results indicated that the average concentrations of available Cd, Pb and As were 42.02, 59.31, 11.16 mg·kg -1 , respectively. The average bioavailability coefficients of Cd, Pb, As were 15.75%, 4.18%, 4.93%, respectively. The contaminated degree of Cd in soil was the most serious. The results of spatial analysis obviously indicated that the distribution of Cd, Pb, As presented a strong spatial correlation and homogeneity. And the heavy polluted spots were concentrated in the agricultural areas and garbage dump.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
