Air pollution recieves one of the prime concern in India, primarily due to rapid economic growth, industrialization and urbanization with associated increase in energy demands. Lacks of implementation of environmental regulations are contributing to the bad air quality of most of the Indian cities. Air pollutants produced in any air shed are not completely confined, but at time trespassing all ...

The giant panda (Ailuropoda melanoleuca) is one of the most endangered animals in the world, and it is recognized worldwide as a symbol for conservation. A previous study showed that wild and captive pandas, especially those of the Qinling subspecies, were exposed to toxicants in their diet of bamboo; the ultimate origin of these toxicants is unknown. Here we show that atmospheric deposition is...

Concerns over agriculturally generated atmospheric pollutants necessitate consideration of emission reduction strategies in livestock facility management. Although the association between odors and elevated ammonia (NH3) and dust concentrations remains uncertain with conflicting studies, steps taken to reduce one pollutant may effectively reduce the others as well. Various remedial activities e...

The so-calledAir Quality Index (AQI), expresses the quality of atmospheric air. The overall AQI is determined from the AQIs of some reference air pollutants, which are calculated by a transform of the respective concentrations. Concentrations of air pollutants are compositional data; they are expressed as part of mass of each pollutant in a total air volume or mass. Therefore, air pollution con...

Chromatographic properties of different types of synthetic zeolites and samples of natural mordenite, modified by ion-exchange have been studied. The influence of degree of replacement and character of cations of alkali and alkaline-earth metals and also of silver and copper on chromatographic retainment of constant components of air and its most spread pollutants have been shown. Recommendatio...

A study was conducted to determine the joint effect of gaseous atmospheric pollutants and trace elements on epiphytic lichens. We used our data to test the hypothesis that lichens are generally insensitive to toxic effects of trace elements, and can therefore be used as accumulator organisms to estimate concentrations of these elements in the environment. In a field study in The Netherlands the...

OBJECTIVE To examine the association between wheezing in children and adolescents and living downwind of the dispersion plume of atmospheric pollutants emitted by the Guamaré Petrochemical Complex, in the state of Rio Grande do Norte, Brazil. METHODS Cross-sectional study of wheezing in children and adolescents (aged 0 to 14 years) living in the vicinity of the Guamaré petrochemical complex i...
