“…The world class magmatic deposits of V-Ti magnetite in Panzhihua provide 20% of iron (Fe), 64% of vanadium (V) and 53% of titanium (Ti) supply for China [23]. Long-term mining activities have contaminated soils and sediments in Panzhihua by metals, especially by V, Ti and Fe [24].…”

To provide a basis for using indigenous bacteria for bioremediation of heavy metal contaminated soil, the heavy metal resistance and plant growth-promoting activity of 136 isolates from V-Ti magnetite mine tailing soil were systematically analyzed. Among the 13 identified bacterial genera, the most abundant genus was Bacillus (79 isolates) out of which 32 represented B. subtilis and 14 B. pumilus, followed by Rhizobium sp. (29 isolates) and Ochrobactrum intermedium (13 isolates). Altogether 93 isolates tolerated the highest concentration (1000 mg kg−1) of at least one of the six tested heavy metals. Five strains were tolerant against all the tested heavy metals, 71 strains tolerated 1,000 mg kg−1 cadmium whereas only one strain tolerated 1,000 mg kg−1 cobalt. Altogether 67% of the bacteria produced indoleacetic acid (IAA), a plant growth-promoting phytohormone. The concentration of IAA produced by 53 isolates was higher than 20 µg ml−1. In total 21% of the bacteria produced siderophore (5.50–167.67 µg ml−1) with two Bacillus sp. producing more than 100 µg ml−1. Eighteen isolates produced both IAA and siderophore. The results suggested that the indigenous bacteria in the soil have beneficial characteristics for remediating the contaminated mine tailing soil.

“…The EF reflects the degree of enrichment of an element by dividing its ratio to a normalizing element by the ratio found in the baseline Covelli an Fontolan, 1997;Lee et al, 1997;Prudêncio et al, 2010;Yanguo et al, 2002). This calculus performs in accordance with Eq.…”

“…In the present study, the concept of baseline conditions as defined by Salminen and Gregorauskiene (1997) was preferred to obtain enrichment factors. Here, baseline obtained in La Joya reservoir represents reference concentrations in a region under human disturbance, such as the case of IPB, allowing monitoring environmental changes, as stated by Yanguo et al (2002).…”

Environmentally geochemical characteristics of vanadium in the topsoil in the Panzhihua mining area, Sichuan Province, China

et al. 2009

Vanadium is a trace element, which may be biologically beneficial and possibly essential but certainly harmful to human beings and some living organisms if excessive. After over 40 years of development, the mining industry has caused serious environmental problems in the Panzhihua mining area. Vanadium is significantly accumulated in the soil of the Panzhihua area. Human activities have intensified the pollution and release of vanadium and caused serious damages to the ecological system there. In the past few years, the authors have made investigations into and assessments on the geochemical distribution, chemical speciation, adsorption characteristics and transfer behavior of vanadium in the topsoil in the Panzhihua mining area. The results showed that: (1) the difference in the contents of vanadium in soil between premonsoon and monsoon is insignificant; (2) the adsorption isotherms of vanadium on soil in the Panzhihua mining area are well described by the Langmuir type; (3) the transfer ability of vanadium in soil is interrelated to soil properties; and (4) the chemical speciation of vanadium shows an order of insoluble residue > oxidizable=reducible > soluble component. According to the above results, some countermeasures to control pollution of vanadium in soil should be put forward.
