摘要于2012年9月、2014年3月、2015年6月和2019年6月在天津市八里台公交站采集环境空气样品，分析该微环境中大气可吸入颗粒物（PM₁₀）污染的整体改善趋势以及PM₁₀中碳组分、水溶性离子组分以及元素组分的特征和4次采样之间的差异.结果表明，4次采样的PM₁₀浓度分别为281，217，188，78μg/m³，呈明显下降趋势.其中水溶性离子组分和元素组分浓度逐年降低，但其占比变化不大（平均浓度占比分别为22%和39%），4次采样的二次离子SNA（即SO₄^2-，NO₃^-和NH₄⁺）占PM₁₀比例分别为11%，9%，9%，17%；总碳质量浓度逐年降低，碳组分在PM₁₀中所占的比例呈波动上升的趋势（从18%上升至32%，平均为25%），根据估算结果，4次采样的二次有机碳（SOC）占PM₁₀比例分别为4%，9%，9%，13%.研究显示，天津市交通微环境空气质量改善效果显著，但二次组分（SNA和SOC）在PM₁₀中占比呈上升趋势，需进一步加强二次污染的控制.

Abstract：Ambient air samples were collected at Tianjin Balitai Bus Station in September 2012, February 2014, June 2015 and June 2019 to analyze the overall improvement trend of atmospheric particulate matter (PM₁₀) pollution in the microenvironment as well as the characteristics of the carbonaceous components, water-soluble ionic components and elemental components in PM₁₀ and the differences between the four samplings. The results showed that the PM₁₀ concentrations of the four samples were respectively 281, 217, 188, and 78μg/m³, presenting a significant downward trend. The concentrations of water-soluble ionic and elemental components in PM₁₀ decreased year by year, while their proportions changed a little (22% and 39% separately). The proportion of secondary ions SNA (SO₄^2-, NO₃^-, NH₄⁺) in PM₁₀ of the 4samples was 11%, 9%, 9%, 17%. The concentrations of total carbon decreased year by year, while the proportion of the carbonaceous components in PM₁₀ showed a fluctuating upward trend (increase from 18% to 32%, with an average of 25%). According to the estimation results, the proportion of secondary organic carbon (SOC) in the 4samples in PM₁₀ was 4%, 9%, 9% and 13%, respectively. Our study shows that the air quality of the traffic microenvironment in Tianjin has been improved significantly, but the proportion of secondary components (SNA and SOC) in PM₁₀ showed an increasing trend, it is necessary to further strengthen the control of secondary pollution.

Key words： Tianjin bus station air quality PM₁₀ secondary pollution
