Detecting the concentration of polycyclic aromatic hydrocarbon (PAHs) in aerosol, e.g., PM2.5 and PM10, is important for monitoring and possibly improving air quality. To fully understand the concentration distribution of polycyclic aromatic hydrocarbon in aerosol, five sampling locations were selected. A carefully designed experiment was carried out to …

Similar behaviour has been reported in the Copper [40] and Lead/Zinc Concentrators [22] of Mount Isa Mines. This may be related to changes in the crystal structure of freshly precipitated iron oxyhydroxide species (aging) which may decrease their susceptibility to dissolution in EDTA solutions [41,36]. The concentration of EDTA …
