The measurement systems used for the experimental campaign are based on different physical principles in order to gain more information about the nature of PM. In particular, traditional sensors based on gravimetric measurements were used together with an Electrical Low-Pressure Impactor to have near surface information about the total mass, the main fractions and the size distribution of PM. A Doppler Lidar system was used to obtain vertical profile of wind speed and direction and a portable Lidar system in elastic configuration was used to have real time information on atmospheric particles optical properties with high spatial and temporal resolution. The combination of measurements from optical remote sensing and advanced in situ instrumentation produced a significant increase in the knowledge of particulate matter, its sources and the processes in which it is involved. In particular, this work highlights the capability of the Lidar approach to expand the knowledge of PM evolution in the atmosphere with respect to other stationary measurement techniques, potentially paving the road to new air quality monitoring systems.","PeriodicalId":165416,"journal":{"name":"Air Pollution XXVI","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124076501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gertler","doi":"10.2495/AIR180561","DOIUrl":"https://doi.org/10.2495/AIR180561","url":null,"abstract":"The Orot Rabin power plant is a 2,590 MW coal-fired power plant located along the Mediterranean coast north of Tel Aviv. Close by to the east is the city of Hadera. Due to the predominant east-west wind patterns, both Hadera and the nearby communities may be impacted by stack emissions from the power plant. In addition, on-site storage of coal and coal residue can be a source of fugitive PM emissions. To determine the sources contributing to elevated PM10 levels in the region, a source apportionment study was performed at two locations (Hephziba and Pardes-Channa) during August/October 2017. We applied a microscopic chemical imaging (MCI) methodology based on particle fluorescence to determine PM source contributions in near-real time (GreenVision Systems, Ltd., Tel Aviv, “GVS”). For the Hephziba monitoring site, located closest to the power plant and adjacent to a major highway, the major emissions sources were mobile sources (29.8%) and coal power plant emissions (29.1%). In addition, fugitive coal and coal residue were estimated to contribute 11.5% of the observed PM10. At the Pardes-Channa site, located further inland and in a more residential area, contributors included mobile sources (38.6%), coal power plant emissions (19.3%), and fugitive coal and coal residue (2.7%). These results indicate the significant impact of the power plant on observed PM10 in the region, with the nearby site also experiencing a major contribution from fugitive emissions from the facility. keywords: PM10, source apportionment, air pollution, fugitive emissions.","PeriodicalId":165416,"journal":{"name":"Air Pollution XXVI","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130559728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Broadbent","doi":"10.2495/AIR180421","DOIUrl":"https://doi.org/10.2495/AIR180421","url":null,"abstract":"The San Francisco Bay Area in California is home to over 7 million people, many of whom live in communities that experience elevated levels of toxic air contaminants due to their relative proximity to industrial and mobile sources of air pollution. The Bay Area Air Quality Management District (Air District), the regional air pollution control agency delegated to govern for the San Francisco Bay Area, has been working to reduce these toxic air contaminant levels over the past decade through the implementation of our Community Air Risk Evaluation (CARE) program. The CARE program is our framework for identifying areas within the region with worse-than-average air quality impacts. It combines science-based analysis of air quality disparities and a more collaborative style of community engagement. It has been used to establish targeted incentive programs and expanded stationary source regulations that strive to reduce health risks for our most socioeconomically vulnerable populations. The Air District is now embarking on a renewed effort to eliminate these risks by incorporating more recent air quality and population data into our analysis, by using new provisional strategies to enhance monitoring and modeling, by targeting regulations for large industrial sources of toxic air contaminants and creating additional incentives to clean up mobile sources of diesel particulate matter. This article describes these past and ongoing efforts and specific measures being taken to ultimately eliminate disparities in air pollution in the Bay Area.","PeriodicalId":165416,"journal":{"name":"Air Pollution XXVI","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128549300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"SMALL AIR QUALITY SENSORS: IN VIVO TESTING OF ELECTROCHEMICAL CAIRPOL SENSORS IN COMPARISON TO REFERENCE MEASUREMENT","authors":"P. Bauerová, Zbyněk Novák, Š. Rychlík, J. Keder","doi":"10.2495/AIR180321","DOIUrl":"https://doi.org/10.2495/AIR180321","url":null,"abstract":"Use of small air quality sensors is very popular during last few years not only in research but also in public sector. From scientific point of view there are possibilities to cover larger area in air quality monitoring by adding small and easy affordable sensors into the reference measurement networks. Such an application of sensors can be very useful for identifying new hotspots or for development of finescale air quality modelling. Nevertheless, there are some limits for real-time outdoor monitoring that must be considered – higher detection limits and weak possibility to deal with non-standard conditions (low temperatures or high air humidity). Therefore, it is very important to be careful with data postprocessing and data interpretation to not get misleading air quality information. Despite a few independent studies and tests of different types of small sensors have been already done (by universities, companies and also by EU Reference Laboratories), the standardized procedure for testing and verifying the data quality has not yet been developed. Sharing the field-measurement experience with different sensors and the data correction methods is therefore crucial. Here we provide results from test measurement of set of electrochemical Cairclip sensors (Cairpol, FR) for SO2, NO2, O3/NO2 and CO during summer (in year 2015) and winter period (2017/2018). The best performance both in comparison between pairs and also between sensors and reference monitors (RM) was found out in combined O3/NO2 Cairclip sensor. Nevertheless, the association of sensor’s measured data with sum of O3 and NO2 measured by RM was much better in summer (R2 = 0.88) than in winter period (R2 = 0.31). Based on the known effect of air temperature and humidity on sensors data quality, we further applied some corrections based on dew point deficit (Td deficit). In this way verified data showed significant improvement in relationship with RM data (R2 = 0.88 with improved slope in summer and R2 = 0.58 in winter). Although the quality of sensor’s measurement can be influenced by many factors at once and further research is needed to resolve all uncertainties, the simple corrections based on the most critical meteorological factors can be very effective.","PeriodicalId":165416,"journal":{"name":"Air Pollution XXVI","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129178789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The leading source of nitrogen dioxide (NO2) concentrations in Bristol, United Kingdom is road transport, and Bristol exceeds the annual mean national air quality objective of 40 µg/m3 for NO2 in many locations around the city. Understanding the reasons for residents' modal choice is an important element in managing air quality in the city. The ClairCity Project approach provides insight into how to reduce overall transport demand and identify incentives that will be effective in creating modal switch away from higher polluting private motorised vehicles. From the ClairCity Project survey subset of commuters (n=442), 45% of respondents used cars or vans at least occasionally for their journey to work, with 28% of the total number of commuters relying exclusively on private motorised transport. The majority of these car users (65.6%) said they would prefer not to travel by car to work in the future. Their responses showed a mix of negative perceptions of public transport, geography and health as key motivations. Family responsibilities, lack of safe cycling and walking spaces, poor health and disability, distance, requirements to transport goods as well as themselves and the need for flexibility were all given as barriers to modal switching. This suggests that for car commuters, well-targeted policy interventions could provide practical alternatives that would appeal to those who currently rely on private motorised transport. Understanding citizens' perceptions, behaviours and activities is a key element in decision-making to reduce transport related air quality emissions and concentrations.","PeriodicalId":165416,"journal":{"name":"Air Pollution XXVI","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125991502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
