【摘要】 采集了五个代表性采样点四个季度的TSP、PM₁₀样品,采样高度为人的呼吸带高度.根据监测数据,研究了颗粒物季节性变化规律及在各功能区的分布规律.结果表明,秋季、冬季、春季颗粒物污染重于夏季,交通干道旁的颗粒物污染也较其它功能区严重.对PM₁₀与TSP相关关系的研究表明两者具有较好的相关性,其测定结果的回归方程为PM₁₀=0.710TSP,R=0.986.表明可吸入颗粒物约占总悬浮颗粒物的71%.更多还原

【Abstract】 Four seasons’ TSP and PM₁₀ samples were collected in 5 different function areas of Nanjing.The sampling height is within the height of respiration of normal people.Based on monitoring data,the principles of particles pollution in different season and in different area were studied.The results show that the particles pollution in autumn,winter and spring are more serious than that in summer and the particles pollution in vehicle communication area is more serious than that in other areas as well.The study of the correlation of TSP and PM₁₀ indicates that they are closely interrelated.The regression formula is PM₁₀=0.710TSP,R=0.986 which indicates that PM₁₀ accounts for 71 percent of TSP.更多还原
