Roles of SO_2 oxidation in new particle formation events

Journal of Environmental Sciences 2015年第4期27卷 90-101页

The oxidation of SO2 is commonly regarded as a major driver for new particle formation（NPF） in the atmosphere. In this study, we explored the connection between measured mixing ratio of SO2 and observed long-term（duration 〉 3 hr） and short-term（duration〈 1.5 hr） NPF events at a semi-urban site in Toronto. Apparent NPF rates（J30） showed a moderate correlation with the concentration of sulfuric acid（[H2SO4]） calculated from the measured mixing ratio of SO2 in long-term NPF events and some short-term NPF events（Category I）（R^2= 0.66）. The exponent in the fitting line of J30~ [H2SO4]nin these events was1.6. It was also found that SO2 mixing ratios varied a lot during long-term NPF events,leading to a significant variation of new particle counts. In the SO2-unexplained short-term NPF events（Category II）, analysis showed that new particles were formed aloft and then mixed down to the ground level. Further calculation results showed that sulfuric acid oxidized from SO2 probably made a negligible contribution to the growth of 〉 10 nm new particles.

华北地区是我国空气污染最严重的地区之一.泰山为华北平原最高峰,可代表华北地区背景大气的环境特征.本研究利用2021年6−8月在泰山顶的强化观测数据,开展了基于观测的化学盒子模型模拟,结合位于泰山下国控站点(泰安市监测站)同期监测数据的对比分析,探究了泰山顶夏季PM_(2.5)和O_(3)的污染特征及成因机制.结果表明:①观测期间,泰山顶NO2、SO2、CO的日均浓度均明显低于泰山下,而泰山顶O_(3)浓度相对更高.泰山顶O_(3)浓度超标天数为61 d,超标率为67.0%,最长连续超标天数达23 d;泰山顶PM_(2.5)日均浓度亦略高于泰山下.②泰山顶日间(07:00−17:00)O_(3)浓度主要来源于光化学反应,而夜间主要来源于区域传输.观测期间,泰山顶O_(3)的生成主要处于NO_(x)控制区.③随PM_(2.5)小时平均浓度的增加,其中二次无机盐(硫酸盐、硝酸盐和铵盐)浓度增加的比例大于有机物;与清洁时段(PM_(2.5)小时浓度小于35μg/m^(3)的时段)相比,PM_(2.5)污染时段(PM_(2.5)小时浓度大于35μg/m^(3)的时段)二次无机盐浓度占比增加了13.1%.④泰山顶PM_(2.5)日均浓度和O_(3)日最大8 h平均浓度(MDA8 O_(3)浓度)呈显著正相关(R=0.73,P<0.01).观测期间共发生50次PM_(2.5)和O_(3)小时浓度同步升高的现象,O_(3)浓度平均升速为(10.1±5.3)μg/(m^(3)·h),PM_(2.5)浓度平均升速为(9.5±6.4)μg/(m^(3)·h),二者同步升高的持续时间为2~14 ***_(2.5)和O_(3)小时浓度同步升高的过程倾向于发生在静风时段,与地面污染物向山顶输送、光化学反应、液相反应及残留层中的传输过程有关.研究显示,泰山O_(3)和PM_(2.5)污染防控需关注周边地区污染物排放及残留层传输的影响.

In the last three decades, huge efforts have been taken to improve understanding of the relationship between ambient nucleation of new particles and its impact on the climate in marine boundary layer（MBL）, e.g., CLAW hypothesis and studies related. However, only ＞40-50 nm new particles could be activated as cloud condensation nuclei（CCN） under typical range of water supersatuations occurring in MBL. The knowledge gap still existed, i.e., which chemicals are critical factors in growing nucleated particles to CCN size in MBL. In this study, we found that nucleated particles in MBL cannot grow over 40 nm in absence of strong formation of NH4NO3. However, the strong formation of NH4NO3 together with organics can grow nucleated particles close to or over 50 nm in MBL. These indicate that the strong formation of NH4NO3 is a critical factor to grow nucleated particles to CCN size in MBL. However, the strong formation of NH4NO3 occurred only in polluted air mass in MBL. Thus, ambient nucleation of new particles in clear and remote MBL is probably not a source of CCN due to lack of a strong formation of NH4NO3 and the nucleation may have no impact on the climate.

政府在追求经济增长的同时还兼顾环境效益。为探讨政府的现金补贴政策对排放依赖型生产商的决策以及对环境效益的影响作用,构建政府的现金补贴函数。结果表明:(1)排放依赖型生产商会根据政府的补贴程度在3种排放权获取渠道(政府分配的配额、自身的排放处理或市场购买)间进行选择;(2)随着现金补贴政策的推出,环境效益得到明显提升,且提升空间与政府可调控的补贴参数紧密相关。通过数值分析进一步说明了模型的应用。
