摘要

The Zunyi region in Guizhou province (south China) is well known by the occurrences of Mo-Ni-polyelement black shales that are locally mined and processed for Mo. It was documented that studied soil samples from the Xiao-Zhu, Jiepo-Ling and Tuan Shan Bao Ni-Mo prospects are characterized by anomalous Mo, Ni, As, Cd, Zn, and Cu concentrations. Maximum Mo concentration was found in rice stalk and maximum As concentration in the bulb of edible water plant close to the Xiao-Zhu Mo-Ni mine. Peak Ni, Zn and Hg concentrations were detected in corn grain of the Jiepo-Ling area. Cd accumulates preferentially into tobacco leaves where it reaches maximum values. Rice grain from the Xiao-Zhu area contains anomalous concentrations of Cd and rice grain from the Tuan Shan Bao area contains anomalous concentrations of Cd, Cu and Zn. Corn grain from the Jiepo-Ling area bears anomalous concentrations of Zn, Cd, Cu, Mo and Ni.
