Abstract. Over the past decade, there has been an increasing interest in short-term events that negatively affect air quality such as bonfires and fireworks. High aerosol gas concentrations generated from public or fireworks were measured order to understand night-time chemical processes their atmospheric implications. Nitrogen chemistry was observed during Bonfire Night with nitrogen containing compounds both phases further N2O5 ClNO2 concentrations, which depleted early next morning due...
Emissions from traditional cookstoves are a major health concern in developing world households. Improved can reduce fuel use and pollutant emissions here we compare three types of improved widely used Sub-Saharan Africa. These raised-bed charcoal stove, rocket-type stove using wood straw, gasifier stove. Laboratory measurements were made the main gaseous pollutants, particle size distribution composition. The genotoxicity particles was assessed comet assay. dry had highest emission factors...
Designs of "improved" stoves are introduced recently to benefit the solid fuel consumption cooking activities in developing countries, but uncertainties concerning combustion processes and particulate emissions remain poorly characterized. To help understand this, three examples African cookstoves was investigated laboratory. A typical European heating stove included for comparison purpose. Detailed aerosol were studied real-time with an Aerosol Mass Spectrometer Single Particle Soot...
The outbreak of COVID-19 pandemic in northern Taiwan led to the implementation Level 3 alert measures during 2021 and thereby impacted air quality significantly, which provided an unprecedented opportunity better understand control strategies on pollutants future. This study investigated variations sources, chemical characteristics human health risks PM2.5 comprehensively. mass concentrations decreased from pre-alert by 49.4%, inorganic ions, i.e., NH4+, NO3- SO42-, dropped even more 71%,...
Polycyclic aromatic hydrocarbons (PAHs) with highly toxic compounds mainly exist in small-sized particles and can induce considerable human health risks. Studies on PM2.5-bound PAHs their source-specific risks still remain scarce. Daily PM2.5 samples (n = 119) were collected every three days from 2016 to 2017 Taipei city, Taiwan. Fifteen analyzed via gas chromatography tandem mass spectrometry (GC/MS-MS). We utilized a positive matrix factorization (PMF) model, diagnostic ratios, potential...
Abstract. Over the past decade, there has been an increasing interest in short-term events that negatively affect air quality such as bonfires and fireworks. High aerosol gas concentrations generated from public bonfires/fireworks were measured order to understand night-time chemical processes their atmospheric implications. Nitrate chemistry was observed during bonfire night with nitrogen containing compounds both phase further N2O5 ClNO2 concentrations, which depleted early next morning...
Abstract The Yangtze River (YR) region and cities along the river have severe deterioration of air quality due to urbanization economic development. Black carbon (BC) has significant impacts on climate, however it is poorly characterized across region. Here we report first continuous measurements BC gaseous pollutants YR in wintertime, with an intensive observation period from November 21 December 4, 2015, covering ∼7° longitude over continent China. highly polluted periods (HPP) NO x >80...
