Compositions and pollutant sources of haze in Beijing urban sites

Junmei Wang et al. Environ Sci Pollut Res Int. 2016 May.

Abstract

Haze from urban sites in Beijing was collected with a self-assembled electrostatic dust collector. The sizes and morphologies, thermal properties, and compositions of the particles in the haze were characterized by scanning electronic microscopy (SEM), differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA), and X-ray photoelectric spectroscopy (XPS), respectively. Based on these results, the causes and pollutant sources of the chemicals in the haze were analyzed, and some countermeasures were further advanced to reduce the related pollutant sources.

Keywords: Air cleaning; Composition; Countermeasures; Electrostatic dust collector; Haze; Pollutant source.
