The purpose of this paper is to integrate the concepts of ecosystem services and disservices when assessing the efficacy of using urban forests for mitigating pollution. A brief review of the literature identifies some pollution mitigation ecosystem services provided by urban forests. Existing ecosystem services definitions and typologies from the economics and ecological literature are adapted...

In this paper, we present a decision-making framework (DMF) for reducing ozone pollution in metropolitan Atlanta. High concentrations of ozone at the ground-level continues to be a serious problem in several U.S. cities, and Atlanta is one of the most serious. In contrast to the “trial and error” approach utilized by state government decision makers, our DMF searches for dynamic and focused con...

Particulate matter is a serious source of air pollution in urban areas, where it exerts adverse effects on human health. This article focuses on the study of subduction of shelterbelts for atmospheric particulates. The results suggest that (1) the PM mass concentration is higher in the morning or both morning and noon inside the shelterbelts and lower mass concentrations at other times; (2) the...

Quality evaluation of urban environment is an integral part of efficient urban environment planning and management. The development of fuzzy set theory (FST) and the introduction of FST to the urban study field attempts to incorporate the gradual variation and avoid loss of information. Urban environmental quality assessment pertain to interpretation and forecast of the urban environmental qual...

co2 is the main greenhouse gas which urban forests have a high potential to absorb and sequestrate it. the air pollution of tehran is one of the most important environmental problems of the iran. to do this research 40 years old stands of robinia pseudoacacia and fraxinus rotundifolia and the surrounding barren land ( as blank) were selected in chitgar forest park of tehran and the amount of ca...

Lung cancer is consistently more common in urban areas than in rural. The excess cannot be accounted for by specific occupational hazards but some of it might be due to the presence of carcinogens in urban air. The excess cannot be wholly due to such agents, because the excess in nonsmokers is small and variable. Cigarette consumption has also been greater in urban areas, but it is difficult to...

1.1 Asthma and allergic diseases in children Asthma is the most common chronic illness of childhood in both developed and developing countries and there is a wide concensus that asthma and allergies have become more prevalent among children (Robertson et al., 2004). Among children, higher prevalence rates of asthma have been found in industrialized western countries than in developing countries...

Atmospheric Ammonia Sources during Severe Haze Episodes: Evidence from N‐Stable Isotope in Size-Resolved Aerosol Ammonium” P et al. presented the isotopic measurements of sizeresolved aerosols in Beijing, summarizing that fossil fuelrelated ammonia emissions (including traffic, coal combustion and power plants ammonia slip) have overtaken agricultural activities as the dominant source of atmosp...
