38. Diagnosis of dust- and haze pollution-impacted PM10, PM2.5, and PM1 aerosols observed at Gosan Climate Observatory

Abstract

In East Asia, soil dust is a major component of aerosols and is mixed with various pollutants during transport, resulting in large uncertainty in climate and environmental impact assessment and relevant policymaking. To diagnose the influence of soil dust and anthropogenic pollution on bulk aerosol, we conducted long-term measurements of mass, water-soluble ions, and carbonaceous compounds of PM10, PM2.5, and PM1 at Gosan Climate Observatory, South Korea, from August 2007 to February 2012. The principle component analyses of all measured species reveal that the impact of anthropogenic pollution, soil dust, and agricultural fertilizer accounts for 46 %, 16 %, and 9 % of the total variance, respectively. Particularly, the loadings of agricultural component were high in the warmer months with the least occurrence of high concentration events and have increased over time. In mode analysis of PM10, PM2.5, and PM1 mass concentrations, the mean + σ was comparable to the 90th percentile and thus, suggested as a robust criterion that determines the substantial impact of soil dust and haze pollution on particulate matter. The results of this study imply that non-combustion sources such as soil dust will impose constraints to the reduction of PM2.5 as well as PM10 concentrations. In addition, questions are raised as to whether the yearly average concentration is suitable for environmental standard in northeast Asian region.

Abstract

Using the nearest neighbor index,geographic concentration index,the Gini coefficient and Lorenz curve,this paper measures the space features of the distribution of the rural tourism scenic (spots) in Shanghai.The research results showed that 1) Shanghai Rural tourism scenic (spots) of the nearest neighbor index is 0.656,indicating that their spatial distribution is cohesion;2) its geographic concentration index is 87.200,indicating that the spatial distribution of the relative concentration,and with the results matched the nearest neighbor index;3) its Gini coefficient is 0.9647,C= 0.0353,which shows that spatial distribution is relatively concentrated.Further,the paper try to explore the impact of the fiscal revenue,gross industrial output value,agriculture park infrastructure investment,the resident population density and land area on the spatial distribution features,and to put forward more reasonable layout scheme to promote the development of rural tourism in Shanghai.

41. Identification and Chemical Characteristics of Distinctive Chinese Outflow Plumes Associated with Enhanced Submicron Aerosols at the Gosan Climate Observatory

Abstract

From October till November in 2010 and during March of 2011, when Chinese outflow events were frequently encountered, the chemical composition of submicron particles (PM1.0) was determined hourly using a particle-into-liquid sampler at the Gosan Climate Observatory. Three distinctive pollution plume types were identified: haze aerosols impacted by biomass combustion, nanoparticle bursts associated with outflow from Beijing, and saline soil particles from salt deposits. The highest PM1.0 concentration was observed in a fall haze event, under near-stagnant high-pressure synoptic conditions that were characterized by the lowest visibility (< 5 km) and the highest K+ and OC concentrations, indicating the influence of biomass combustion. When strong high-pressure systems develop in China, they efficiently export fresh urban emissions from Beijing to the study region, as distinguished by nanoparticle bursts of > 10(4) cm(-3) with highly elevated SO2 levels, even during the night. When air masses move rapidly from northeastern China to Gosan under strong wind conditions, the Ca2+ concentration, along with that of Cl- and Na+, is enhanced in PM1.0, which is attributed to the influence of saline transport from dry lakes. The results of this study reveal compositional details and information on both number and mass concentration for different PM1.0 plumes from anthropogenic and natural sources, all of which are associated with different kinds of Chinese outflow events.

42. A semi-continuous study on the toxicity of atmospheric particles using a versatile aerosol concentration enrichment system (VACES): development and field characterization.

Abstract

The toxicity of atmospheric particles directly associates to health effects, but its online monitoring has not yet been implemented due to low-concentration toxic components and high measurement detection limit. To solve the detection problem, we extended a versatile aerosol concentration enrichment system (VACES) for toxicity aerosol measurement and firstly used VACES to provide a comparison of toxicity between non-concentrated and concentrated aerosols in ambient air. Through optimizing the technical parameters, the total concentration (number or mass), the concentration of chemical components, and the toxicity were all increased by approximately 7 to 10 times in VACES. In particular, ambient aerosols with toxicity below the detection limit, were detected significantly after concentration. Moreover, comparable enrichment factors and similar trends before and after enrichment in toxicity were observed over time, suggesting that the toxic properties of ambient aerosols do not change in VACES. Whereas, changes in PM2.5 concentrations and their toxicity do not always correlate well, which was probably driven by the combined toxicity effect of chemical components. Thereby, it hints a necessity to further study on the toxicity effects of chemical compositions. All above also imply that VACES could provide technical support for the future measurement of online atmospheric particulate toxicity, which is currently performed at high-concentration environment, long sampling duration, and offline.

Abstract

Particulate nitrite is a critical source of hydroxyl radicals; however, it lacks high-resolution methods due to its low abundance and stability to explore its formation mechanism. In this study, a modified versatile aerosol concentration enrichment system (VACES) coupled with ion chromatography (IC) was used to measure particulate NO 2 - hourly online and achieve a lowered detection limit of 10 -3 μg m -3 . VACES-IC was used to observe a high- and low-concentration events of PM 1.0 -NO 2 - in Shanghai, corresponding to the ambient-level concentrations of 0.34 and 0.05 μg m -3 , respectively. The morning peak concentrations of NO 2 - even exceeded 3σ (standard deviation) in the high-concentration event due to the reduction of NO 2 by aerosol SO 3 2- based on kinetics and regression analysis. This implies that controlling SO 2 emissions would be an effective strategy to decrease morning NO 2 - concentrations, correspondingly reducing the kinetic formation of SO 4 2- by 20.8-34.8%. However, after sunrise, NO 2 - formation was primarily attributed to NO 2 hydrolysis at pH 4.97-6.14. In the low-concentration event, NO 2 hydrolysis also accounted for an overwhelming proportion (∼90%) of NO 2 - formation. This work estimates the contribution of different paths to particulate NO 2 - formation based on newly established high-resolution measurements.
