Stringent emission controls during the Asia Pacific Economic Cooperation Summit (APEC; November 5-11, 2014) provide a valuable opportunity to examine the impact of such measures on the chemical properties of PM2.5 and other air pollutants. Here, we measured the water-soluble inorganic ions (WSII) and carbonaceous species in PM2.5NH3 and NO2 at multiple sites in Beijing between September and November 2014. Relative to the pre-APEC period (September and October 2014), significant reductions in the average concentrations of WSII (69% for NO3, 68% for SO42-, 78% for NH4+, and 29-71% for other species), elemental carbon (EC, 43%) and organic carbon (OC, 45%) in PM2.5 were found during the APEC period. The contributions of secondary inorganic ions (SIA, including SO42-, NO3-, and NH4+) to PM2.5 were significantly lower during the APEC period (9-44%), indicating a combination of lower gaseous precursor emissions and a relative weak secondary aerosol formation. Ion-balance calculations indicated that the PM2.5 sample in the pre-APEC period was alkaline but was acidic during the APEC period. Relatively lower mean concentrations of EC (1.5 mu g m(-3)), OC (10.5 mu g m(-3)), secondary organic carbon (SOC, 3.3 mu g m(-3)), secondary organic aerosol (SOA, 5.9 mu g m(-3)) and primary organic aerosol (POA, 10.0 mu g m(-3)) appeared during the APEC period. The average concentrations of NH3 and NO2 at all road sites were significantly reduced by 48 and 60% during the APEC period, which is consistent with clear reductions in satellite NH3 columns over Beijing city in the same period. This finding suggests that reducing traffic emissions could be a feasible method to control urban NH3 pollution. During the APEC period, concentrations of PM2.5, PM10, NO2, SO2 and CO from the Beijing city monitoring network showed significant reductions at urban (20-60%) and rural (18-57%) sites, whereas O-3 concentrations increased significantly (by 93% and 53%, respectively). The control measures taken in the APEC period substantially decreased PM2.5 pollution but can increase ground O-3, which also merits attention.

Impact of flow velocity on the heterogeneous reaction of SO2 over Fe2O3

Yangyang Liu, Tao Wang, Qiuyue Ge, Zhuocheng Shi, Kejian Li, Kedong Gong, Lifang Xie, Wei Wang, Qianlong Wang, Jin Han, Hongbo Fu, Jianmin Chen, Liwu Zhang

Summary: Flow velocity is found to play a crucial role in the heterogeneous oxidation of SO2 on alpha-Fe2O3 particles, with increased velocity significantly enhancing the oxidation capability. Specimen analysis suggests a shift in the oxidation mechanism from a heterogeneous reaction mediated by active sites under low flow velocity to an aqueous-like multiphase-dominated pathway under high flow velocity. This study highlights the importance of flow velocity in triggering fast sulfate production in dust chemistry.

Yangyang Zhang, Xin Ma, Aohan Tang, Yunting Fang, Tom Misselbrook, Xuejun Liu

Summary: Reducing atmospheric ammonia (NH3) emissions is crucial for improving air quality. However, the sources of NH3 emissions in different regions remain unclear, hindering the implementation of effective reduction strategies. This study in China found that both agricultural and non-agricultural sources contribute to NH3, with non-agricultural sources (such as traffic and waste) playing a significant role. It is important to address these non-agricultural sources when reducing ambient NH3 levels, even in rural regions.

Spatial distributions of particle number size distributions generated during cooking processes and the impacts of range hoods

Longbo Shi, Zhi Liu, Wen Wen, Jung Hyun Son, Ling Li, Lina Wang, Jianmin Chen

Summary: Cooking oil fume (COF) is associated with health risks, and this study investigated the particle number size distribution (PNSD) of COF and its spatial distribution and influencing factors. The PNSD was found to follow a lognormal distribution, with peak diameters decreasing as the distance from the source increased. The decrease in temperature from the pot to the indoor environment led to a reduction in surface partial pressure of COF particles and the condensation of semi-volatile organic carbons (SVOCs) on the COF surface. The amount of edible oil used in dishes was positively correlated with COF concentration. Techniques for cleaning small size particles and improving air ventilation should be considered.

Abundant Cyanobacteria in Autumn Adhering to the Heating, Ventilation, and Air-Conditioning (HVAC) in Shanghai

Changliang Nie, Xueyun Geng, Runqi Zhang, Lina Wang, Ling Li, Jianmin Chen

Summary: This study investigated the presence of cyanobacteria on the pre-filter of HVAC systems and found that the concentrations were highest in autumn and significantly higher compared to winter and summer. The airborne transportation of aquatic and terrestrial cyanobacteria contributed to their presence on the pre-filter. The dominant cyanobacteria families identified were Chroococcidiopsaceae, norank_cyanobacteriales, Nostocaceae, and Paraspirulinaceae. Some detected genera, such as Nodularia sp., Pseudanabaena sp., and Leptolyngbya sp., potentially produced cyanobacterial toxins that could pose a threat to human health. This study provides new insights into the distribution of cyanobacteria outside of aquatic habitats.

Contribution of chemical composition to oxidative potential of atmospheric particles at a rural and an urban site in the Po Valley: Influence of high ammonia agriculture emissions

Maria Chiara Pietrogrande, Beatrice Biffi, Cristina Colombi, Eleonora Cuccia, Umberto Dal Santo, Luisa Romanato

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
