Research ArticleOpen accessIn the keywordsThe Impact of Anthropogenic Activities Recorded By Mercury in the Sediment from Dianshan LakeHui Zhang, Nan Zhang, Qi Yang et al.The mercury in sediment cores from Dianshan Lake, Shanghai is studied in this study and it indicates that the mercury level changing from 52.78-145.66 µg kg-1 in sediment can be obviously divided into three sections responding to the development of economy of Shanghai. Mercury decreases with depth in 0-11 cm underground, which is corresponding to the depositing period after 1980; … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 4 Aug 2012 · 7,022 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsComparison of Two Analytical Techniques For Lead Determination in Soils and Mosses SamplesAlbert Maxhuni, Pranvera Lazo, Musaj PaqariziThe aim of this study was to compare the results of the lead levels obtained by two different techniques in the soil and mosses samples taken from the entire territory of the Republic of Kosovo. The atmospheric deposition of lead through the biomonitoring technique was done for the first time in Kosovo by using quartz tube flame Atomic Absorption Spectroscopy … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 22 Jun 2012 · 6,902 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsForest Fires and Resuspension of Radionuclides into the AtmosphereFernando P. Carvalho, Joao M. Oliveira, Margarida MaltaProblem statement: Forest fires are especially frequent around the Mediterranean Sea basin in the summer period and might be able to release naturally-occurring and man-made radionuclides from plant biomass and inject them into the atmosphere. The impact of this radioactivity on populations was not investigated before. Approach: Radionuclide analysis was performed in plants, in smoke from plant burning and in … …American Journal of Environmental Sciences, Vol. 8, Issue 1 · 14 Jan 2012 · 7,362 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEnvironmental Assessment of Dust-Holding and Oxygen-Producing Productivity of Hawthorns in KazakhstanBotagoz Kentbayeva, Zhadyra Baigazakova, Mukhtar Baybatshanov et al.The research aimed to study the oxygen productionand the dynamics of the leaf blade dust-collecting ability of hawthorns growingin contrasting ecological and climatic areas. Hawthorns in urban green spacesare a fairly common tree species and play an important hygienic role inpurifying the atmospheric air from dust and harmful impurities and havesufficient oxygen productivity. Hawthorn trunks ensure 70% of all oxygenproductivity … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 9 Sep 2022 · 5,449 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHard Coal Fly Ash and Silica-Effect of Fine Particulate Matter Deposits on Brassica chinensisChristian Ulrichs, Uwe Schmidt, Tanja Mucha-Pelzer et al.Problem statement: One focus in recent atmospheric pollution research is on fine Particle Matter (PM), especially as result of increasing traffic and anthropogenic activity in urban areas. Here, the impact on animal and human health has been in the center of many studies. Despite the fact that PM depositions can affect plants on the long term, there are only few … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 8,650 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordHealth Impacts Estimation of Mineralogical and Chemical Characterization of Suspended Atmospheric Particles over the East DesertU. Ali Rahoma, Elsayed EmaraProblem statement: The small size fraction of aerosols, measured as PM10 and PM2.5, rather than the larger particles, is considered to be responsible for most of the health effects. Such particles have a relatively long residence time in the atmosphere and can therefore travel over long distances. Hence, a large portion of ambient concentrations of PM10 and in particular of … …American Journal of Infectious Diseases, Vol. 6, Issue 3 · 30 Sep 2010 · 10,775 accessesView PDF Cite
