Biogenic VOCs emission inventory development of temperate grassland vegetation in Xilin River basin, Inner Mongolia, China

Given the key role of biogenic volatile organic compounds(VOCs) to tropospheric chemistry and regional air quality, it is important to generate accurateVOCs emission inventories. However, only a less fraction of plant species, in temperate grassland of Inner Mongolia, has been characterized by quantitative measurements. A taxonomic methodology, which assigns VOCs measurements to unmeasured species, is an applicable and inexpensive alternation for extensive VOCs emission survey, although data are needed for additional plant families and genera to further validate the taxonomic approach in grassland vegetation. In this experiment, VOCs emission rates of 178 plant species were measured with a portable photoionization detector( PID). The results showed the most of genera and some families have consistent feature of their VOCs emission, especially for isoprene, and provide the basic premise of taxonomic methodology to develop VOCs emission inventories for temperate grassland. Then, the taxonomic methodology was introduced into assigning emission rate to other 96 species, which no measured emission rates available here. A systematical emission inventory of temperate grassland vegetation in Inner Mongolia was provided and further evidence that taxonomy relationship can serve as a useful guide for generalizing the emissions behavior of many, but not all, plant families and genera to grassland vegetation.     

Progress in quantitative research on the relationship between atmospheric oxidation and air quality

Atmospheric oxidizing capacity (AOC) is an essential driving force of troposphere chemistry and self-cleaning, but the definition of AOC and its quantitative representation remain uncertain. Driven by national demand for air pollution control in recent years, Chinese scholars have carried out studies on theories of atmospheric chemistry and have made considerable progress in AOC research. This paper will give a brief review of these developments. First, AOC indexes were established that represent apparent atmospheric oxidizing ability (AOIe) and potential atmospheric oxidizing ability (AOIp) based on aspects of macrothermodynamics and microdynamics, respectively. A closed study refined the quantitative contributions of heterogeneous chemistry to AOC in Beijing, and these AOC methods were further applied in Beijing-Tianjin-Hebei and key areas across the country. In addition, the detection of ground or vertical profiles for atmospheric OH·, HO₂·, NO₃· radicals and reservoir molecules can now be obtained with domestic instruments in diverse environments. Moreover, laboratory smoke chamber simulations revealed heterogeneous processes involving reactions of O₃ and NO₂, which are typical oxidants in the surface/interface atmosphere, and the evolutionary and budgetary implications of atmospheric oxidants reacting under multispecies, multiphase and multi-interface conditions were obtained. Finally, based on the GRAPES-CUACE adjoint model improved by Chinese scholars, simulations of key substances affecting atmospheric oxidation and secondary organic and inorganic aerosol formation have been optimized. Normalized numerical simulations of AOIe and AOIp were performed, and regional coordination of AOC was adjusted. An optimized plan for controlling O₃ and PM_2.5 was analyzed by scenario simulation.

应用PCR-DGGE技术研究处理含氨废气的生物滤塔中微生物多样性

变性梯度凝胶电泳技术(DGGE)在微生物生态学领域有着广泛的应用.本文应用DGGE技术对处理含氨废气的生物滤塔中微生物多样性随时间的变化进行了研究.在生物滤塔运行的不同时间采集滤塔中的填料样品,进行了生物滤塔对氨处理效果的分析和DGGE分析.结果显示,污泥和混合填料生物滤塔氨的出气浓度在经过一段时间后,逐渐升高,而堆肥生物滤塔的运行情况较好,对氨的去除效率始终在98%以上.PCR-DGGE图谱显示,不同时间的相同填料中微生物DGGE图谱有着明显的差异性.Shannon指数分析表明,填料中微生物的多样性都随着反应器运行时间的延长而有所减少.运行一个月后,混合填料的微生物多样性指数最低为0.389;其次为污泥填料,其多样性指数为0.473;堆肥填料的微生物多样性程度最高为0.569.生物滤塔对氨的去除效果与填料中微生物多样性Shannon指数之间有一定的相关关系.主成分分析(PCA)显示对于堆肥和污泥来说,填料样品之间微生物群落结构相似性较高,而混合填料样品间的微生物群落结构相似性较低.
