摘要: 利用天津市生态环境监测中心2018年1月~3月期间的黑碳、颗粒物和气象因素观测数据，探究天津市冬季黑碳气溶胶浓度的变化趋势及其污染特征。结果表明，观测期间，黑碳气溶胶浓度均值为2.92 μg/m3，占PM10质量浓度的3.04%，其吸收消光占气溶胶总体消光的15.3%。受人类活动和气象条件影响，黑碳气溶胶浓度日变化呈双峰型，8:00达到峰值，14:00~16:00最小，22:00达到一天中最大值。黑碳气溶胶浓度随风速升高呈下降趋势，当风速大于4 m/s时，黑碳气溶胶浓度较低。西风、西南风及西北风对天津城区黑碳气溶胶输送作用明显，易出现大于10 μg/m3的高黑碳气溶胶事件。
Abstract: Based on the observation data of black carbon, particulate matter and meteorological factors of Tianjin Eco-Environmental Monitoring Center from January to March 2018, the variation trend and pollution characteristics of black carbon aerosol concentration in winter in Tianjin were explored. The results show that the average concentration of black carbon aerosol is 2.92 μg/m3, which takes up 3.04% of the mass concentration of PM10 and 15.3% of the total extinction of aerosol. Under the influence of human activities and meteorological conditions, the diurnal variation of black carbon aerosol concentration shows a bimodal pattern, reaching a peak at 8:00, a minimum from 14:00 to 16:00, and a maximum at 22:00. The concentration of black carbon aerosol decreases with the increase of wind speed. When the wind speed exceeds 4 m/s, the concentration of black carbon aerosol is lower. West wind, southwest wind and northwest wind have obvious influence on black carbon aerosol transport in Tianjin city area; high black carbon aerosol events greater than 10 μg/m3 are easy to occur.
