摘　　要：为研究廉江市大气颗粒物污染特征,于2014年11月~12月采集TSP、PM10、PM2.5样品,用重量法分析质量浓度,并对相关性进行分析。结果表明,用环境空气质量标准（GB 3095-2012）来衡量,廉江市冬季大气颗粒物TSP、PM10、PM2.5的日均浓度均符合标准,环境空气状况良好;三个代表性采样点在监测周期内TSP、PM10、PM2.5的浓度变化趋势大体一致,监测结果能客观反映该区域颗粒物的污染状况;PM2.5与PM10,PM10与TSP之间均存在着显著相关性,回归方程相关性较好。For the study of Lianjiang atmospheric particulate matter pollution characteristics,this studygathered the TSP,PM10 and PM2. 5samplesfrom November to December 2014 toanalyze its mass concentration by weight method,and analyzes its relevance. Results show that with the ambient air quality standard（ GB 3095-2012）,Lianjiang winter atmospheric particulates TSP,PM10 and PM2. 5daily average concentration conforms to the standards of environment air in good condition; Three representative sample point within the monitoring period of TSP,PM10 and PM2. 5concentrations is broadly in line with a change trend. The monitoring results can objectively reflect the status of the region of particulate matter pollution; there is a significant correlation between PM10 and TSP,PM2. 5and PM10,the regression equation of the correlation is better.
