Models of atmospheric composition rely on fire emissions inventories to reconstruct and project impacts biomass burning air quality, public health, climate, ecosystem dynamics, land-atmosphere exchanges. Many such global use satellite measurements active fires and/or burned area from the Moderate Resolution Imaging Spectroradiometer (MODIS). However, differences across in interpretation imagery, factors assumed for different components smoke, adjustments made small obscured can result large...
Abstract. The health implications of PM2.5 in the tropical region Southeast Asia (SEA) are significant as can pose serious concerns. concentration and sources here strongly influenced by changes monsoon regime from south-west quadrant to north-east region. In this work, samples were collected at a semi-urban area using high-volume air sampler different seasons on 24 h basis. Analysis trace elements water-soluble ions was performed inductively coupled plasma mass spectroscopy (ICP-MS) ion...
In this work, we report a facile synthesis of graphene oxide-gold (GO-Au) nanocomposites by electrodeposition. The fabricated electrochemical immunosensors are utilized for the dual detection severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antigen and SARS-CoV-2 antibody. GO-Au has been characterized UV-vis spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), cyclic voltammetry (CV), differential pulse (DPV), impedance spectroscopy (EIS) its biosensing...
In this study, we show that black carbon (BC) mass concentrations measured by different techniques are consistent and traceable. First, present the volatilities of 13 organic compounds passed through a heated inlet. These data were used to quantify interference aerosols on BC measurement techniques. The masses refractory particles incandesce (m*ref) calibrate single-particle soot photometer (SP2), which uses laser-induced incandescence. This calibration was influenced little organics agreed...
Abstract. This study investigates the fine particulate matter (PM2.5) variability in Klang Valley urban-industrial environment. In total, 94 daily PM2.5 samples were collected during a 1-year campaign from August 2011 to July 2012. is first paper on mass, chemical composition and sources tropical environment of Southeast Asia, covering all four seasons (distinguished by wind flow patterns) including haze events. The analysed for various inorganic components black carbon (BC). compositions...
Abstract. Indonesia contains large areas of peatland that have been drained and cleared natural vegetation, making them susceptible to burning. Peat fires emit considerable amounts carbon dioxide, particulate matter (PM) other trace gases, contributing climate change causing regional air pollution. However, emissions from peat are uncertain, due uncertainties in emission factors fuel consumption. We used the Weather Research Forecasting model with chemistry measurements PM concentrations...
Abstract Particulate matter (PM) emissions from vegetation and peat fires in Equatorial Asia cause poor regional air quality. Burning is greatest during drought years, resulting strong inter-annual variability emissions. We make the first consistent estimate of emissions, quality public health impacts Asian 2004–2015. The largest dry season (August—October) occurred 2015, with PM estimated as 9.4 Tg, more than triple average emission (2.7 Tg). Fires Sumatra Kalimantan caused 94% Asia. Peat...
Air pollution has been creating severe environmental crises in Dhaka. This city ranks at the top among major cities of world. A multidimensional study is needed to assess severity this crisis. aims determine sources trace elements PM2.5 and their effects on health. We measured concentrations 15 every hour for eight days using a well-equipped mobile air quality monitoring system integrated with an automatic sampling (AQMS, Horiba, Japan). analyzed identify potential diurnal variation compute...
