Lead levels and isotopic compositions in atmospheric particles (TSP and PM2.5), street dust and surface soil collected from Nanjing, a mega city in China, were analyzed to investigate the contamination and the transfer of lead in urban environmental compartments. The lead contents in TSP and PM2.5 are significantly higher than them in the surface soil and street dust (p < 0.05). The enrichment...
A new protocol using zincon-immobilized silica-coated magnetic Fe 3 O 4 nanoparticles (Zincon–Si–MNPs) as solid-phase extraction (SPE) medium has been developed for the separation and preconcentration of trace lead in water. Various parameters such as pH, extraction time, concentration and volume of eluent, sample volume, and influence of co-existing ions have been investigated in...
Contents of heavy metals in six vegetable species and the corresponding rhizospheric soils around a lead-zinc mining and smelting plant in Nanjing, China were investigated to assess the possible risks of heavy metal posed to human health through food chain and to discuss the relationships of heavy metals contents in vegetables and the corresponding rhizospheric soils. Compared to national sanitation...
