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...

In the era of globalization and international trade, the production-based CO2 emissions accounting system, proposed by United Nations Framework Convention on Climate Change, can easily lead to a “carbon leakage” issue. Thus, the accounting of consumption-based carbon emissions and carbon emissions embodied in international trade has received considerable research attention. Nevertheless, resear...

The gases emissions measurement systems in internal combustion engines are strict and expensive nowadays. For this reason, a virtual instrument was developed to measure the combustion emissions from an internal combustion diesel engine, running with diesel-biodiesel mixtures. This software is called virtual instrument for emissions measurement (VIEM), and it was developed in the platform of Lab...

Burning fuels with high sulfur content leads to SOx emissions, especially SO2, which various environmental and health problems. The maritime sector is responsible for 13% of the global anthropogenic emissions SO2. Thus, International Maritime Organization (IMO) has issued a protocol, known as MARPOL Annex VI, aims further limit SO2 derived from ships along NOx, particulate matter volatile organ...

A key question in developing effective mitigation strategies for ozone and particulate matter is identifying which source regions contribute to concentrations in receptor regions. Using a direct approach with a regional, multiscale three-dimensional model, we derive multiple sourcereceptor matrices (S-Rs) to show interand intrastate impacts of emissions on both ozone and PM2.5 over the eastern ...

In the context of international efforts to reduce the impacts of atmospheric NH3 and NH4+ (collectively, NHx). it is important to establish the link between NH3 emissions and monitoring of NHx concentrations and deposition. This is equally relevant to situations where NH3 emissions changes are certain (e.g. due to changed source sector activity), as to cases where NH3 abatement technologies hav...

Current regulation aimed at reducing inorganic atmospheric fine particulate matter (PM2.5) is focused on reductions in sulfur dioxide (SO2) and oxides of nitrogen (NO(x) = NO + NO2); however, controls on these pollutants are likely to increase in cost and decrease in effectiveness in the future. A supplementary strategy is reduction in ammonia (NH3) emissions, yet an evaluation of controls on a...

      In order to ensure the safety of parenterals, international pharmacopoeias and national standards have set up stringent guidelines and standards. Particulate con- tamination is a potential health risk caused by intravenous injection of particles large enough to potentially clog the small arteries. Particles could be produced through manufacturing and packaging or even dispensing of the ph...

[1] A high-resolution (1 1 , 27 vertical levels) Eulerian chemical transport and transformation model for sulfate, SO2, and related species driven by analyzed forecast meteorological data has been run for the Northern Hemisphere for June–July 1997 and extensively evaluated with observational data, mainly from air quality and precipitation chemistry networks. For 5000 evaluations, 50% of the mod...

The inorganic aerosol system of sulfate, nitrate, and ammonium can respond non-linearly to changes in precursor sulfur dioxide (SO2) emissions. The potential increase in nitrate, when sulfate is reduced and the associated ammonia is released, can negate the sulfate mass reduction. Current regional-scale air quality models do not reproduce the present-day levels of total ammonia and total nitrat...
