ABSTRACT

ABSTRACT: A study on PM2.5 was conducted in a metropolis in Central China from July 2006 to July 2007 that acquired 24h mass and chemical composition every sixth day at three sites, one industrial, one urban and one urban-industrial site. The PM2.5 samples were pre-treated and both inorganic and organic compounds were measured. The levels, seasonal and spatial patterns and detailed chemical characterizations of major constituents were identified. This study will help better understand the causes and reduction strategies for PM2.5 in Central China.
