lichen species (hypogymnia physodes and evernia prunastri) were used for biomonitoring thepossible air pollution with heavy metals in the vicinity of copper mine in the eastern part of the republic ofmacedonia. the contents of 18 elements were analysed by icp-aes and etaas techniques. for dataprocessing basic statistical methods and multivariate exploratory (factor and cluster analysis) techniq...

Atmospheric mercury can be considered a ‘hot topic’. The problem of global mercury pollution is a focus of several international conventions such as the UNEP mercury program and the UN-ECE Long-Range Transport of Atmospheric Pollution Convention Task Force on Hemispheric Transport of Air pollution (HTAP). Major scientific questions are the oxidization processes of elemental mercury, global and ...

introduction population growth, along with the rapid development in industrial and many urban sectors, and lack of sustainable development approach in urban planning are all caused great changes in environment in form of pollution and ravage. in urban environments, complexity of spaces and urban manmade phenomena as well as the lack of regular and continuous measurement of atmospheric elements ...

Leaded gasoline in Taiwan was gradually phased out from 1983 to 2000. However, it is unclear whether unleaded gasoline still contributes to atmospheric lead (Pb) exposure in urban areas. In this study, Pb isotopic compositions of unleaded gasolines, with octane numbers of 92, 95, 98, and diesel from two local suppliers in Taipei were determined by multi-collector inductively coupled plasma mass...

Researchers or decision-makers frequently need information about atmospheric pollution patterns in urbanized areas. The preparation of this type of information is a complex task, due to the influence of several individual pollutants, with different units, on the global air pollution (e.g. nitrogen dioxide concentrations, ppm, and noise, dB). In this work, a new methodology based on the formulat...

Atmospheric Chemistry and Physics Discussions This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract Sea-land and mount-valley circulations are the dominant mesoscale synoptic systems affecting the Beijing area during summertime. Under the influence of these two circulati...

Air pollution is becoming a serious challenge in thickly populated areas the world. The air Kurdistan region clearly noticed, especially where sources and human population are concentrated. Urbanization economic growth proceeding at rapid pace, accompanied by increasing emissions of mixture greenhouse gases from transporting sector, that positively contribute to accelerate climate change around...
