In this study, the contribution of fuels (coal + natural gas) used for residential heating in Kayseri city center to air pollution was investigated. For reason, amount emissions released atmosphere calculated by using gas and coal data residences 5 (five) year period between 2015-2019 province Kayseri. addition, percentage both industrial point sources terms compared. The relationship annual av...

The prevalence of allergic rhinitis, a common respiratory disorder, may be rapidly increasing. Epidemiological studies, however, indicate little about its association with climatic factors and air pollution. The relationship between traffic-related air pollutants and allergic rhinitis in middle-school students was therefore investigated. In a nationwide survey of middle-school students in Taiwa...

The high-order decoupled direct method in three dimensions for particulate matter (HDDM-3D/PM) has been implemented in the Community Multiscale Air Quality (CMAQ) model to enable advanced sensitivity analysis. The major effort of this work is to develop highorder DDM sensitivity analysis of ISORROPIA, the inorganic aerosol module of CMAQ. A case-specific approach has been applied, and the sensi...

Direct emissions of air pollutants from the cement industry in China were estimated by developing a technology-based methodology using information on the proportion of cement produced from different types of kilns and the emission standards for the Chinese cement industry. Historical emissions of sulfur dioxide (SO2), nitrogen oxides (NOX), carbon monoxide (CO), particulate matter (PM) and carb...

Manganese oxide-supported palygorskite (MnOx/PG) catalysts are considered highly efficient for low-temperature SCR of NOx. However, the MnOx/PG catalyst tends to be poisoned by SO2. The effect SO2 on activity SO2-pretreated poisoning under ammonia-free conditions was explored. It determined that considerably deactivated in absence ammonia and water-washed regeneration can completely recover cat...

this study was focused on measuring air pollutants emission from factories producing the asphalt related products in delijan industrial estate, which is the main center of asphalt related products in iran. emissions of four factories were analyzed for air pollutants using a stack analyzer, testo 360, testo co., and germany. the average concentration of all measured stacks for pm, thc, co, nox, ...

The dry treatment of flue gas produced by incineration processes is discussed thermodynamically. The study investigates the theoretical limits achieved by sodium and calcium based sorbents in the removal of the pollutant species HCl, NOx and SO2. Calculations were performed varying the temperature and the molar ratio between the amount of the injected alkaline sorbent and the content of the pol...

Emissions from 15 agricultural fires in the southeastern U.S. were measured from the NASA DC-8 research aircraft during the summer 2013 Studies of Emissions and Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys (SEACRS) campaign. This study reports a detailed set of emission factors (EFs) for 25 trace gases and 6 fine particle species. The chemical evolution of the primar...

BACKGROUND In our previous experimental studies, we found evidence for the increase of nitric oxide (NO) formation immediately after blast injury. In the present study we investigated whether NO overproduction was a trait for the period immediately after blast injury in humans. Concomitant metabolic disturbances were also studied, and compared to the alterations in other traumatized patients. ...
