The impact of manufacturing transfer in Jiangsu province, China, on the spatial-temporal variations of SO2 emissions is investigated using estimated sector-specific SO2 emissions, and emissions in the different transfer-in and transfer-out regions were quantified during 2000–2011. Our results show that SO2 emissions had undergone three phases: an increase in the period of 2000–2005, a rapid dec...

PA Rule Targets Smokestack Pollution In July 2011 the U.S. EPA finalized the CrossState Air Pollution Rule to reduce SO2 and NOX emissions from power plants using available emissions control technologies. SO2 and NOX contribute to ground-level ozone and fine particle pollution and often cross state lines, ending up far from their provenance. The rule is projected to achieve up to $280 billion i...

Chronic high surface ozone (O3) levels and the increasing sulfur oxides (SOx = SO2+SO4) ambient concentrations over South Coast (SC) and other areas of California (CA) are affected by both local emissions and long-range transport. In this paper, multi-scale tracer, full-chemistry and adjoint simulations using the STEM atmospheric chemistry model are conducted to assess the contribution of local...

We discuss collection 2 SO2 data from the DutchFinnish Ozone Monitoring Instrument (OMI) on board NASA EOS/Aura spacecraft and show examples of detected volcanic and anthropogenic SO2 emissions. Quantification of anthropogenic SO2 emissions requires collection 3 reprocessing available in the fall 2007.

Background: The international drug abuse standards were achieved by review of a vast meta-analysis in the world and released 2 years ago in Vienna. Review of national programs in recent 20 years and conformity of them is the main objective of this presentation. Methods: Based on research that was supported by UNODC and DCHQ, the demand reduction program in Iran at the mentioned time was studied...

background: air pollution and concerns about health impacts have been raised in metropolitan cities like tehran. trend and prediction of air pollutants can show the effectiveness of strategies for the management and control of air pollution. artificial neural network (ann) technique is widely used as a reliable method for modeling of air pollutants in urban areas. therefore, the aim of current ...

In this study, we compare the potential influence of inter-continental transport of sulfate aerosols on the air quality of continental regions. We use a global chemical transport model, Model of Ozone and Related Tracers, version 2 (MOZART-2), to quantify the source-receptor relationships of inter-continental transport of sulfate aerosols among ten regions in 2000. In order to compare the impor...
