  • Air pollution deprivation and health understanding relationships to add value to local Air Quality Management policy and practice in wales uk
    Journal of Public Health, 2016
    Co-Authors: James Longhurst, Jo Barnes, Huw Brunt, Gabriel Scally, Sarah J Jones, Enda T Hayes
    Abstract:

    Background Air pollution exposure reduces life expectancy. Air pollution, deprivation and poor-health status combinations can create increased and disproportionate disease burdens. Problems and solutions are rarely considered in a broad public health context, but doing so can add value to Air Quality Management efforts by reducing Air pollution risks, impacts and inequalities. Methods An ecological study assessed small-area associations between Air pollution (nitrogen dioxide and particulate matter), deprivation status and health outcomes in Wales, UK. Results Air pollution concentrations were highest in ‘most’ deprived areas. When considered separately, deprivation-health associations were stronger than Air pollution-health associations. Considered simultaneously, Air pollution added to deprivation-health associations; interactions between Air pollution and deprivation modified and strengthened associations with all-cause and respiratory disease mortality, especially in ‘most’ deprived areas where most-vulnerable people lived and where health needs were greatest. Conclusion There is a need to reduce Air pollution-related risks for all. However, it is also the case that greater health gains can result from considering local Air pollution problems and solutions in the context of wider health-determinants and acting on a better understanding of relationships. Informed and co-ordinated Air pollution mitigation and public health action in high deprivation and pollution areas can reduce risks and inequalities. To achieve this, greater public health integration and collaboration in local Air Quality Management policy and practice is needed.

  • local Air Quality Management policy and practice in the uk the case for greater public health integration and engagement
    Environmental Science & Policy, 2016
    Co-Authors: James Longhurst, Jo Barnes, Huw Brunt, Gabriel Scally, Enda T Hayes
    Abstract:

    Abstract The UK’s Local Air Quality Management (LAQM) regime is designed to protect people’s health from the ill-effects of Air pollution, but it is failing to achieve its full potential. The Public Health aspects of, perspectives on, and integration and engagement in, LAQM have been poorly considered to date. This critical literature review assessed LAQM-related strengths and limitations in order to explore how Public Health, through greater integration and engagement, can add value to the regime. ‘Structure’ and ‘process’ weaknesses were identified, including: a poorly defined Public Health role, a narrowly-scoped prescribed process, risk assessment uncertainties, ineffective communications, shallow evaluations and disconnected policies. Separately and cumulatively, these have hindered Public Health integration in LAQM policy and practice and stunted the regime's evolution. Engaging Public Health in LAQM future design and delivery can help solve these problems, by improving risk assessments and raising awareness of Air pollution and other health-influencing relationships, targeting action in high-need areas, coordinating Air pollution mitigation and health improvement interventions, and connecting different policy areas. Increasing Public Health integration and engagement in LAQM can enhance the existing regime. Acting now is timely from both LAQM and Public Health perspectives. This review's findings should be used to inform debates and decisions around the future development of Local Air Quality Management arrangements both in the UK and beyond.

  • is local Air Quality Management a successful strategy for achieving selected eu limit values
    Artificial Intelligence Review, 2014
    Co-Authors: Jo Barnes, Enda T Hayes, James Longhurst
    Abstract:

    This research examines the role of Local Air Quality Management Action Planning in achieving the EU limit value for nitrogen dioxide (NO2) annual mean, focusing on those Air Quality Management Areas (AQMAs) declared in England before July 2005 for exceedences of the NO2 annual mean objective from road traffic sources. The paper describes the initial stages of the methodology, analysing the availability of Air Quality Action Plans (AQAPs) and annual mean NO2 monitoring data. The research finds an absence of government monitoring sites with adequate nitrogen dioxide data relative to the selected AQMAs, as well as an absence of AQAPs and annual progress reports. The paper concludes that Local Air Quality Management is insufficiently calibrated to provide adequate support to the achievement of the EU limit value for NO2 annual mean.

  • Air Quality action planning why do barriers to remediation in local Air Quality Management remain
    Journal of Environmental Planning and Management, 2014
    Co-Authors: Joanna H Barnes, Enda T Hayes, Tim Chatterton, James Longhurst
    Abstract:

    UK local Air Quality action planning has failed to remediate exceedances of Air Quality targets, particularly for nitrogen dioxide, which are widespread and persistent a decade after the first local action plans were drafted. This paper is relevant to a range of administrations charged with managing Air Quality. Using a literature review and local authority survey, it explores barriers to improving Air Quality, i.e. resource limitations, absence of local authority powers, and a lack of intra-governmental co-operation and inter-governmental co-ordination. It concludes that the causes of these inefficiencies are flawed subsidiarity and devolved responsibility decoupled from the powers necessary to implement required actions. Challenging opportunities to reconceptualise Air Quality action planning to protect public health are suggested.

  • Air Quality action planning barriers to remediation in local Air Quality Management
    Artificial Intelligence Review, 2012
    Co-Authors: Jo Barnes, James Longhurst, Enda T Hayes, A O Olowoporoku
    Abstract:

    This paper explores the operation of Air Quality action planning within the framework of UK Air Quality Management with particular reference to the key actors and actions. The paper examines the intentions of action planning policy and reflects on the role of local government in achieving these intentions. A review of primary sources and peer-reviewed literature identifies some of the barriers to action plan implementation and explores why these barriers remain in place after more than a decade of action. As a nationally mandated but locally operated policy, it is argued that there is a mismatch between ambition, powers and effects. The paper concludes with an exploration of the opportunities to reconceptualise and re-energise the Air Quality action planning process in order to provide appropriate protection for public health.

    Co-Authors: S.m. Shiva Nagendra, Mukesh Khare, Uwe Schlink, M. Diya
    Abstract:

    Urban Air Quality is a critical issue in both developed and developing countries. In the recent past, the governments in both the developed and developing countries have initiated several strategies and action plans to address the urban Air Quality issues. This chapter discusses the principles of Air Quality Management, framework for Air Quality Management, Air Quality standards and legislations, Air Quality Management practices in selected countries and challenges in Air Quality Management.

  • ambient Air pollutant monitoring and analysis protocol for low and middle income countries an element of comprehensive urban Air Quality Management framework
    Atmospheric Environment, 2020
    Co-Authors: Sunil Gulia, Isha Khanna, Komal Shukla, Mukesh Khare
    Abstract:

    Abstract Rapid urbanization along with industrial growth is one of the major causes of elevated Air pollution levels in urban areas of low and middle income countries (LMICs). They are further associated with adverse health impacts within urban ecosystems. In order to manage and control deteriorating urban Air Quality, an efficient and effective urban Air Quality Management plan is required consisting of systematic sampling, monitoring and analysis; modelling; and control protocols. Air Quality monitoring is the essential and basic step that develops foundation of any Management plan. The present research article describes a comprehensive methodology for establishing a systematic and robust Air Quality monitoring network in LMICs and strengthening the effectiveness and efficiency of urban Air Quality Management frameworks. It also describes step-by-step procedures for chemical characterization of both organic and inorganic constituents of ambient particulate matter along with molecular markers, which are essential to identify the corresponding sources of particulate matter, an integral part of Air pollution monitoring protocol. Additionally, it discusses the need for coupling low cost wireless sensor-based stations with a limited number of manual and conventional real time ambient Air monitoring stations in order to make it cost effective, yet robust. The article demonstrates that satellite-based remote sensing monitoring calibrated with ground level measurement has the potential for regional scale Air Quality monitoring that captures transport of transboundary pollution.

  • urban local Air Quality Management framework for non attainment areas in indian cities
    Science of The Total Environment, 2018
    Co-Authors: Sunil Gulia, Jo Barnes, S Shiva M Nagendra, Mukesh Khare
    Abstract:

    Increasing urban Air pollution level in Indian cities is one of the major concerns for policy makers due to its impact on public health. The growth in population and increase in associated motorised road transport demand is one of the major causes of increasing Air pollution in most urban areas along with other sources e.g., road dust, construction dust, biomass burning etc. The present study documents the development of an urban local Air Quality Management (ULAQM) framework at urban hotspots (non-attainment area) and a pathway for the flow of information from goal setting to policy making. The ULAQM also includes assessment and Management of Air pollution episodic conditions at these hotspots, which currently available city/regional-scale Air Quality Management plans do not address. The prediction of extreme pollutant concentrations using a hybrid model differentiates the ULAQM from other existing Air Quality Management plans. The developed ULAQM framework has been applied and validated at one of the busiest traffic intersections in Delhi and Chennai cities. Various scenarios have been tested targeting the effective reductions in elevated levels of NOx and PM2.5 concentrations. The results indicate that a developed ULAQM framework is capable of providing an evidence-based graded action to reduce ambient pollution levels within the specified standard level at pre-identified locations. The ULAQM framework methodology is generalised and therefore can be applied to other non-attainment areas of the country.

  • Urban Air Quality Management-A review
    Atmospheric Pollution Research, 2015
    Co-Authors: Sunil Gulia, S.m. Shiva Nagendra, Mushti V. Ramakrishna, Surya Nepal, Mukesh Khare, Isha Khanna
    Abstract:

    Abstract Urban Air Quality Management plan (UAQMP) is an effective and efficient tool employed in managing acceptable urban Air Quality. However, the {UAQM} practices are specific to a country’s needs and requirements. Majority of the developed countries have full–fledged {UAQMP} with a regulatory Management framework. However, developing countries are still working in formulating the effective and efficient {UAQMPs} to manage their deteriorating urban Air environment. The first step in the process of formulation of {UAQMP} is to identify the Air Quality control regions based on ambient Air Quality status and second, initiate a time bound program involving all stakeholders to develop UAQMPs. The successful implementation of {UAQMPs} depends on the strength of its key components, e.g. goal/objective, monitoring network, emission inventory, Air Quality modeling, control strategies and public participation. This paper presents a comprehensive review on UAQMPs, being implemented worldwide at different scales e.g., national (macro), city (medium), and local (micro).

  • performance evaluation of iscst3 adms urban and aermod for urban Air Quality Management in a mega city of india
    International Journal of Sustainable Development and Planning, 2014
    Co-Authors: Sunil Gulia, Somanath Nagendra, Mukesh Khare
    Abstract:

    Urban Air Quality has deteriorated in last few decades in the mega cities of both developed and developing countries. Many mathematical models have been widely used as prediction tool for urban Air Quality Management in developed countries. However, applications of these models are limited in developing countries including India due to lack of suffi cient validation studies. In this paper, three state-of-the-art Air Quality models namely AERMOD, ADMS-Urban and ISCST3 have been used to predict the Air Quality at an intersection in Delhi city, India, followed by their performance evaluation and sensitive analysis under different meteorological conditions. The models have been run for different climatic conditions, i.e. summer and winter season to predict the concentration of carbon monoxide (CO), nitrogen dioxide (NO 2 ) and PM 2.5 (diameter size less than 2.5 µm). The ISCST3 has performed satisfactorily (d = 0.69) for predicting CO concentrations when compared with AERMOD (d = 0.50) and ADMS-Urban (d = 0.45) for winter period. The ADMS-Urban (d = 0.49) has performed satisfactorily for predicting NO 2 concentration when compared with ISCST3 (d = 0.36) and AERMOD (d = 0.32). The AERMOD, ISCST3 and ADMS-Urban have performed satisfactorily for predicting PM 2.5 concentrations having d values as 0.46, 0.45 and 0.43 respectively. All three models have performed satisfactorily for predicting CO concentrations when wind speed was in the range of 0.5–3 m/s and wind direction in the range 90–180 degrees, i.e. downwind direction. The difference in model’s performance may be due to differences in model formulation and the treatment of terrain features. The causal nature of these Gaussian based models may be one of the reasons for difference in performance of the models, because these are sensitive to

  • application of adms and aermod models tostudy the dispersion of vehicular pollutants inurban areas of india and the united kingdom
    Artificial Intelligence Review, 2012
    Co-Authors: Somanath Nagendra, Sunil Gulia, V. S. Chithra, Pallavi Vijay, M.c. Bell, Mukesh Khare, Anil Namdeo
    Abstract:

    Urban Air pollution poses a significant threat to human health, the environment and the Quality of life of people throughout the world. In the United Kingdom 103 areas have been declared as local Air Quality Management areas (LAQMA). While in India, 72 cities have been identified as cities having poor Air Quality/non-attainment area, i.e., the Air Quality in these cities are exceeding prescribed National Ambient Air Quality Standards (NAAQS). The transport sector is the principal source of local Air pollution in urban areas, because of the increased vehicular population, vehicle kilometres travelled (VKT) and lack of infrastructure development. Many mathematical models have been widely used as tools in local Air Quality Management in developed countries. Among them, ADMS [1] and AERMOD [2] models have been widely used for urban Air Quality Management in Europe and the US, respectively. However, their applications are limited in developing countries like India due to the lack of readily available input data, time and the cost involved in collecting the required model input data. In this paper the performance evaluation of ADMS and AERMOD in predicting particulate matter (PM) concentrations at road sides in Chennai, India and Newcastle, UK is discussed.

Results indicated that both the models are able to predict the pollutant concentrations with reasonable accuracy. The IA values for ADMS and AERMOD are found to be 0.39 and 0.37 and 0.48 and 0.44, respectively, for the Chennai and Newcastle study sites.

  • science policy interplay Air Quality Management in the pearl river delta region and hong kong
    Atmospheric Environment, 2013
    Co-Authors: Liuju Zhong, Peter K K Louie, Junyu Zheng, Zibing Yuan, Dingli Yue, Alexis K H Lau
    Abstract:

    Abstract The information provided by the scientific studies and control measures implemented in the Pearl River Delta (PRD) region of China reveals that tremendous progress has been made in the understanding of regional Air pollution issues and the deployment of mitigation measures for alleviating these problems. Given the unparalleled rapid economic growth in the PRD over the past two decades, such progress was only made possible by strong, science-based support and the partnerships between government and research institutions in the region and overseas. Researchers from these partnership programs and related studies have deployed cutting-edge expertise and experience in various crucial mainland China and mainland China/Hong Kong-level projects. China recognizes the importance of protecting the environment and cleaning up the Air in the pursuit of sustainable growth and economic development. To avoid falling into a cycle of event-driven clean-up efforts, China has recently taken a major step and updated the national ambient Air Quality standards. Clearly, China is implementing an increasing number of evidence-based policies to address Air pollution problems. Thus, to bring a fresh impetus at a national level, the PRD must maintain and augment the Hong Kong-mainland collaborative momentum, inducing a “whole-China” effort to clean up Air pollution. To strengthen the science-based support system and ensure continuous and concerted effort in implementing the regional multi-pollutant control strategy, there must be an overarching and integral Hong Kong–Guangdong science consortium framework supporting the formulation of regional policy and control measures built on common goals under the “one country, two systems” principle. The “PRD Approach” of the Air Quality Management regime reflected regional cooperative efforts in synchronous Air pollutant control, catalyzed the crucial role of information disclosure and subtly transformed the Air Quality Management approach to overcome the nation's new Air pollution challenges.

  • the pearl river delta regional Air Quality monitoring network regional collaborative efforts on joint Air Quality Management
    Aerosol and Air Quality Research, 2013
    Co-Authors: Liuju Zhong, Peter K K Louie, Junyu Zheng, Zibing Yuan, Dingli Yue, Alexis K H Lau, Kong Max Wai, Yan Zhou
    Abstract:

    ABSTRACTThe Guangdong and Hong Kong governments have collaboratively established the first Pearl River Delta regional Air Quality monitoring network (“PRD RAQMN”) since November 2005 which represented the first joint Air Quality monitoring of the regional Air pollution and reporting efforts at a rapidly developed and heavy-polluted area in the southern China. The PRD RAQMN keeps track on the long-term evolution of Air pollution status in the PRD region located in the south coast of China. It recorded the Air Quality trend during the 11th Five-Year Plan (FYP) implemented between 2006 and 2010, and the years of synchronous of leapfrogging economic development and stringent emission control on coal-fired power plants and vehicles for the 12th FYP to be implemented between 2011 and 2015. The PRD RAQMN showcases as a role model for the cooperation of local administrative authorities and also serves the surveillance system for joint prevention and Management of Air pollution. The PRD RAQMN catalyzed the cooperation among regions in the nation and public dissemination of Air Quality information which is otherwise under tight scrutiny in the past. The PRD RAQMN demonstrates that the regional collaboration and formation of consortium is critical in Air Quality Management strategy to address and resolve the Air pollution problems in China more effectively.
