The emission of sulfur dioxide (SO2, also SO3) and nitrogen oxides (NO, NO2, called NOX) from burning fossil fuel, especially coal which is used to produce energy (electricity and heat) is one of the most important sources of environmental and air pollution. These pollutants are known as "acid gases" causing acid rain and also "indirect greenhouse gases" contributing greenhouse effect. Acid rai...
We estimated PM2.5-related public health impacts/ton emitted of primary PM2.5, SO2, and NOx for a set of power plants in the Mid-Atlantic and Lower Great Lakes regions of the United States, selected to include varying emission profiles and broad geographic representation. We then developed a regression model explaining variability in impacts per ton emitted using the population distributions ar...
This study explores the relationship between happiness and air pollution in Britain using data from the British Household Panel Survey (BHPS). The effects of air pollution on individuals’ happiness are estimated and their monetary value is calculated. In particular, three air pollutants are examined in this paper; the sulphur dioxide (SO2), the ground-level ozone (O3) and the nitrogen dioxides ...
This paper discusses the importance of background concentrations of NH3, SO2 and NOx for the estimation of environmental external costs of secondary particulates. A modified version of the ECOSENSE software was developed within the ongoing series of European ExternE projects, devoted to the assessment of energy related environmental external costs. Using the Windrose Trajectory Model the yearly...
BACKGROUND There is evidence that long term exposure to ambient air pollution increases the risk of childhood asthma, but the role of different sources and components needs further elaboration. To assess the effect of air pollutants on the risk of asthma among school children, a nationwide cross sectional study of 32 672 Taiwanese school children was conducted in 2001. METHODS Routine air pol...

This paper examines the impact of various nitrogen oxides (NOx) and sulfur dioxide (SO2) emission control scenarios on the projected prices of electricity in the state of Indiana. The scenarios represent different methods for achieving the reductions in NOx and SO2 emissions mandated by the United States Environmental Protection Agency (EPA) under its Clean Air Interstate Rule (CAIR). The analy...
یکی از منابع تولید انرژی، نیروگاه های برق است این نیروگاه ها نیاز اساسی انسان ها را تامین می کند و از اهمیت خاصی بر خـوردار می باشد بر اثر به آلاینده هایی که نیروگاه های برق تولید می کند سلامت انسان ها در معرض خطر قرار می گیرد. از همین رو یکی از مسایل و مشکلات اساسی نیروگاه های تولید برق ،کنترل و پیشگیری از انتشار بیش ازحد مجاز آلاینده ها به خصوص دی اکسید گوگرد (SO2 ) و اکسیدهای نیتروژن (NOx) م...
Secondary organic aerosol (SOA) constitutes a substantial fraction of fine particulate matter and has important impacts on climate and human health. The extent to which human activities alter SOA formation from biogenic emissions in the atmosphere is largely undetermined. Here, we present direct observational evidence on the magnitude of anthropogenic influence on biogenic SOA formation based o...
