We assess the effectiveness of these pretreatments in enhancing the concentration of valuable metals and compare the metal content before and after treatment. Our findings reveal that water washing significantly enhances fly ash’s zinc and copper content, surpassing the minimum industrial-grade requirements. Mechanical sieving is an efficient pretreatment method for bottom ash, with the zinc concentration inversely related to particle size. Additionally, copper content peaks in the 1 - 2 mm particle size range for both bottom ash samples. These results provide valuable insights into the potential for metal recovery from MSWI residues. They hold significance for relevant research, engineering practices, and policy formulation.展开更多

We selected Masson pine (Pinus massoniana L.) as potential biomonitor and collected the current (C) and previous year (C+ 1) needles from three industrial sites dominated by petrochemical, ceramics manufacturing, and iron and steel smelting plants and one remote site to determine heavy metals (Cu, Cd, Pb, Zn, Cr, Ni and Co) and polycyclic aromatic hydrocarbons (PAHs) in unwashed and water-washed needles. Both unwashed and washed C+ 1 needles showed generally higher concentrations of heavy metals and PAHs than C needles, although the washed needles more clearly spotlighted the accumulation effect of PAHs over exposure time. Water-washing resulted in a significant decrease in needle PAH concentrations with more significant effects shown in C needles. By contrast, needle heavy metal concentrations were much less affected by washing. Although heavy metals and PAHs might differ in adsorption and uptake strategies, their higher concentrations in the needles at the industrial sites indicated conspicuous contamination due to industrial emissions there. The PAH distribution patterns in pine needles accorded with the real types of energy consumption in the study sites and were efficiently used for pinpointing local pollutant sources.展开更多
