Urban centers in Latin American often face high levels of air pollution as a result of economic and industrial growth. Decisions with regard to industry, transportation, and development will affect air pollution and health both in the short term and in the far future through climate change. We investigated the pollution health consequences of modest changes in fossil fuel use for three case stu...

IN T R O D U C T IO N In recent years there has been a growing concern about the rapidly deteriorating environment in the urban areas of this country in terms of air, water, and noise pollution. Automobile transportation has been found to be a significant factor in the deterioration of the urban environment, particularly in regard to air pollution. In general, con­ sidering the total tonnage of...

We used the case-crossover design to identify any increase in mortality in Seoul, Korea, when there were higher levels of ambient air pollution on case-days than would be expected solely as a result of chance. This empirical study showed that either unidirectional retrospective (selecting only control days prior to death) or prospective (selecting only control days after death) control sampling...

stationary sources are reponsible to 96.8 of sox and 70.1 percent of nox in tehran. there are more than 70 thousands factories located in tehran region. economic policy measures such as, charges, subsidies, and non-compliance fees, and also marketable permits, bubble policy, offets, netting and reforms in banking, are recommended. automobiles produce 71.2 percent of total air pollution in tehra...

Abstract: Recently, China has brought out several air-pollution control policies, which indicate the prominent position that PV power hold in improving atmosphere environment. Under this policy environment, the development of China’s PV power will be greatly affected. Firstly, after analyzing the influencing path of air-pollution control policies on PV power, this paper built a system dynamics ...

The ambient air quality monitoring was carried during the May 2003 to April 2004 along the (NH-6) passing through Jalgaon city. The average concentration of SOx 64 microg/m3, NOx 58 microg/ m3, particulates (> 10 micro) 515 microg/m3 and respirable dust particulates 224 microg/m3 was reported at Prabhat during the study period (May 2003-April 2004). This location represents the major highway cr...

Air Pollution monitoring and measurement are generally done using sampling techniques and analysis equipment often heavy, complex and expensive. Although these methods offer a high measurement precision which is essential to answer standards requirements, they are not adapted for quality oriented applications where simple information with low precision can be sufficient. The use of semiconducto...

This paper was prepared to provide an overview of current air pollution training in the United States for the S-l1 Education and Training Committee, APCA. An earlier report by Sholtes! reviewed the wide range of training going on in 1966. The number of programs has significantly increased; therefore, the present study has been focused on training efforts at colleges and universities leading to ...

Air pollution caused due to the introduction of particulate matters, biological molecules and other harmful materials into the Earth's atmosphere. Pollution brings vital diseases, death to humans, damages other living organisms such as vegetations, animals, natural environment and built environment. Data mining concerned with finding hidden patterns inside largely available data, so that the in...

BACKGROUND Pregnant women and their fetus belong to a sensitive group in response to air pollution hazards. The aim of this study was to evaluate the effectiveness of a theory-based educational program to change pollution exposure behavior in pregnant women. METHODS In this randomized controlled trial, pregnant women attending a prenatal clinic in Tehran, Iran were selected and randomized int...
