Bioavailable Vanadium Eztracting with EDTA in Panzhihua Urban Park Topsoil
Vanadium was a trace element, which may be biologically beneficial and possibly essential but certainly harmful to human beings and some living organisms if excessive. In order to investigate potentially environmental risk of vanadium, a total of 46 topsoil samples were collected in dry and wet season in Panzhihua urban park. The concentration of bioavailable vanadium in wet season was higher than that in the dry season. The higher concentration of bioavailable vanadium was distributed in the gateway, the childrens pleasure ground and the resting place. In contrast to the toxicity reference values(TRV) in Eco-SSLs for vanadium in the soil and bioavailable vanadium, there was a slight health risk. So some countermeasures of reducing pollution of vanadium in urban park soil should be put forward.
