Effects of mining on the molybdenum absorption and translocation of plants in the Luanchuan molybdenum mine.

ABSTRACT:

Background

There is a critical need to examine whether mining of molybdenum (Mo) ore will affect Mo absorption and translocation by plants at a community level.

Methods

Indigenous plants and their rhizospheric soil (0-20 cm) growing in two different areas including the mining and the unexploited areas were collected from the Luanchuan Mo mine-one of the largest Mo mines in Asia. The concentrations of Mo and other heavy metals of plants or soil were measured by ICP-AES. Mo absorption and translocation in plants growing in two areas were investigated and compared. Heavy metal pollution in soil was also evaluated by the potential ecological hazard index method.

Results

Mo concentration in mining soils was higher with the changes from 108.13 to 268.13 mg kg^-1 c
