air quality is a topic of crucial importance, because air pollution is one of the most important pollution problems in the world. in particular, predicting or detecting a future extreme air pollution episode or predicting the violation of an air quality standard, is of crucial interest in the field of pollution control. there have been a variety of attempts to reach this purpose both from the p...

during the last years, several exceedances of pm10 and benzo(a)pyrene limit values exceedances were recorded in taranto, a city in southern italy included in so-called areas at high risk of environmental crisis because of the presence of a heavy industrial district including the largest steel factory in europe. a study of these critical pollution events showed a close correlation with the wind ...

among human activities, motor vehicles play the most important role in air pollution. air pollution has negative impacts on people and on the environment. in this paper the effect of oxygen-enriched air (20.8%, 21.8%, 22.8%, 23.8% and 24.8%) and different bioethanol-gasoline blends (zero, 5%, 10%, 15%, 20% and 25%) in different engine speeds (1000 rpm, 2000 rpm and 3000 rpm) on the amount of po...

asthma and atopic dermatitis are common allergic diseases, and their prevalence has increased in urban children. recently, it is becoming understood that forest environment has favorable health effects in patients with chronic diseases. to investigate favorable clinical and immunologic effects of forest, we examined changes in clinical symptoms, indirect airway inflammatory marker, and serum ch...

infrastructure development being the major construction activity undertaken with the support of the government to eradicate poor transport infrastructure, to cater to ever-increasing population, to reduce the usage of own vehicle and environmental impact thereof, the concept of mass rapid transit system came into existence. among the various mass rapid transit system modes, metro rail construct...

BACKGROUND Preterm delivery and preeclampsia are common adverse pregnancy outcomes that have been inconsistently associated with ambient air pollutant exposures. OBJECTIVES We aimed to prospectively examine relations between exposures to ambient carbon monoxide (CO) and fine particulate matter [≤ 2.5 μm in aerodynamic diameter (PM2.5)] and risks of preeclampsia and preterm delivery. METHODS...

There are a number of applied settings where a response is measured repeatedly over time, and the impact of a stimulus at one time is distributed over several subsequent response measures. In the motivating application the stimulus is an air pollutant such as airborne particulate matter and the response is mortality. However, several other variables (e.g. daily temperature) impact the response ...

The distribution of Particulate Matter in the atmosphere, resulting from emissions produced by cars, trucks, ships, industrial estates and agricultural complexes, is a topical public health problem that has increased in recent decades due to environmental factors in advanced economies in particular. This contribution relates the health impact caused by concentrations of Particulate Matter (PM) ...

BACKGROUND Air pollution data in Bangkok, Thailand, indicate that levels of particulate matter with aerodynamic diameter < or = 10 microm (PM(10)) are significantly higher than in most cities in North America and Western Europe, where the health effects of PM(10) are well documented. However, the pollution mix, seasonality, and demographics are different from those in developed Western countrie...

Several studies have shown the association between ambient particulate matter (PM) and adverse health effects and climate change, thus highlighting the need to limit the anthropogenic sources of PM. PM Exposure is commonly monitored as mass concentration of PM10 (particle aerodynamic diameter < 10μm) or PM2.5 (particle aerodynamic diameter < 2.5μm), although increasing toxicity with decreasing ...
