    The APAD and ASFID: long-term fine and coarse ambient particulate matter and source fingerprint databases for the Asia-Pacific region
    (Clean Air Society of Australia and New Zealand, 2016-08-01) Atanacio, AJ; Cohen, DD; Begum, BA; Ni, BF; Pandit, GG; Sahu, SK; Santoso, M; Lestiani, DD; Lim, JM; Rahman, SA; Elias, MS; Shagjjamba, D; Markwitz, A; Waheed, S; Siddique, N; Pabroa, PCB; Santos, FL; Seneviratne, MCS; Handagiripathira, L; Wimolwattanapun, W; Vuong, TB; Karydas, A
    Ambient particulate matter (APM) pollution, often generically referred to as smog or haze, is a global problem impacting every country and region in the world to varying degrees. Countries within the rapidly developing Asia-Pacific region have much higher levels of APM compared with many internationally recognised health goals. This paper presents two new aerosol databases compiled as the result of a long-term project spanning 15 years and involving 14 countries in the Asia-Pacific region under the auspices of the International Atomic Energy Agency (IAEA). The first database, named the Asia-Pacific Aerosol Database (APAD), contains the elemental concentration and associated error and minimum detectable limits (MDL) for 14,016 APM samples collected between 2002 and 2015. The second database, named the Asia-Pacific Source Fingerprint Database (ASFID), contains receptor source fingerprints and source apportionment solutions obtained by each country from their APAD dataset using positive matrix factorisation (PMF) methods. © 2016 The Clean Air Society of Australia and New Zealand

    Fingerprinting and source apportionment of fine particle pollution in Manila by IBA and PMF techniques: a 7-year study
    (Wiley-Blackwell, 2009-01) Cohen, DD; Stelcer, E; Santos, FL; Prior, MJ; Thompson, C; Pabroa, PCB
    X-ray and ion beam analysis (IBA) techniques have been used to characterize fine particle pollution in Manila over a 7-year period. These data have then been used in the latest statistical methods of positive matrix factorization (PMF) to quantitatively identify source fingerprints and their contributions to the total fine particulate mass. © 2008, Wiley-Blackwell.

    Urban air quality in the Asian region
    (Elsevier, 2008-10-01) Hopke, PK; Cohen, DD; Begum, BA; Biswas, SK; Ni, BF; Pandit, GG; Santoso, M; Chung, YS; Davy, P; Markwitz, A; Waheed, S; Siddique, N; Santos, FL; Pabroa, PCB; Seneviratne, MCS; Wimolwattanapun, W; Bunprapob, S; Vuong, TB; Hien, PD; Markowicz, A
    Over the past decade, member states of the Regional Co-operation Agreement (RCA), an intergovernmental agreement for the East Asia and Pacific region under the auspices of the IAEA with the assistance of international organizations and financial institutions such as the World Bank and the Asian Development Bank, have started to set in place policies and legislation for air pollution abatement. To support planning and evaluate the effectiveness of control programs, data are needed that characterizes urban air quality. The focus of this measurement program describe in this report is on size segregated particulate air pollution. Such airborne particulate matter can have a significant impact on human health and urban visibility. These data provide the input to receptor models that may permit the mitigation of these impacts by identification and quantitative apportionment of the particle sources. The aim of this report is to provide an overview of the measurements of concentrations and composition of particulate air pollution in two size fractions across the participating countries. For many of the large cities in this region, the measured particulate matter concentrations are greater than air quality standards or guidelines that have been adopted in developed countries. © 2008, Elsevier Ltd.
