Air pollution is a major concern worldwide with human activities being the main contributor and causing serious health impacts. The present study was designed to monitor amount of gaseous pollutants (CO2, CO, SO2, NOX) total suspended particulates (TSP) from different industrial boiler’s exhaust using three fuel types (coal, natural gas heavy furnace oil/diesel). These five parameters were meas...
OBJECTIVE To examine associations between ambient air pollutants and respiratory outcomes among schoolchildren in Durban, South Africa. METHODS Primary schools from within each of seven communities in two regions of Durban (the highly industrialised south compared with the non-industrial north) were selected. Children from randomly selected grade 4 classrooms were invited to participate. Stan...
Air quality policy to decrease fine particulate matter mass concentrations (PM2.5) in the US has mainly targeted sulfate aerosol through controls on sulfur dioxide (SO2) emissions. Organic aerosol (OA) instead of sulfate is now the dominant component of total PM2.5. Long-term surface observations (1991–2013) in the Southeast US in summer show parallel decreases in sulfate (2.8%–4.0% a ) and OA ...
Measurements of gaseous SO2, NO, NO2, H2S, O3, NH3 and VOCs, in Kuwait city using IVL passive sampler technology, were obtained on monthly basis during the period from March 2011 to February 2012 at 10 locations. The results of this study reveal that those compounds had low concentrations compared to Kuwait Environment Public Authority standards for residential areas. It is found that nitrogen ...
Coal-fired power plants in the United States may have to reduce their mercury emissions by up to 90% by 2007 2009 due to proposed regulations that could affect up to 1,100 utility boilers. Air pollution control system components such as electrostatic precipitators, baghouses, NOx reduction catalysts, SO2 scrubbers, and their various configurations in utility applications significantly impact me...
In urban areas, emissions of air pollutants by anthropogenic processes such as traffic, industry, power plants and domestic heating systems are the main sources of pollution (Fenger, 1999). The massive growth in road traffic and in the use of fossil fuels during the last decades has changed the composition of urban air, increasing the frequency of pollution episodes and the number of cities exp...
Industrial agglomeration is a major source of regional economic development and the main pattern enterprises employ after having developed to certain stage. also affects emissions air pollutants in production. Based on provincial panel data for China from 2006 2019, this paper introduces full generalized least squares (FGLS) econometrics model. By considering spatial correlation, potential endo...
population growth, industrial pollution and high-energy consumption, cause the release of significant amounts of pollutants in the environment. power plants play an important role in the release of pollutants such as sulfur dioxide, nitrogen oxides, and carbon dioxide. if the necessary measures in the field of prevention and control do not be implemented, human health and other living creatures...
ship exhaust emission inventories and their associated externalities constitute valuableinformation resources towards policy making and management of the influence exerted by shipping on airquality. to this extent, the container terminal at the greek port of piraeus by virtue of its shipping significanceand its urbanised character was selected in order to provide an estimation of the emissions ...
In recent years, global warming and climate change associated with emissions of CO2 from fossil fuel-fired power systems are a big worry for authorities in many countries worldwide. The utilization biomass as an alternative, carbon-neutral fuel can reduce other greenhouse gases. Furthermore, the coupling oxy-combustion capture is option carbon-negative generation technology. this study, NOx, SO...
