Research ArticleOpen accessIn the abstractElemental Composition and Concentration of Atmospheric Particulate Matter in KuwaitJasem M. Al-Awadhi, Anwar B. Al-HelalHourly PM10 and PM2.5 samples were simultaneously collected at 10 and 3 urban sites, respectively in Kuwait from March 2014 to February 2015, to study the air quality and heavy metals content and Total Petroleum Hydrocarbons (TPHs) in PM10 samples. The annual average concentrations of PM10 and PM2.5 were 152 and 97.3 μg/m3, respectively, with an average PM2.5/PM10 ratio of … …American Journal of Environmental Sciences, Vol. 13, Issue 1 · 18 Feb 2017 · 7,623 accessesView PDFCite
Research ArticleOpen accessIn the abstractCHARACTERIZATION OF OIL PALM EMPTY FRUIT BUNCH AND RICE HUSK BIOCHARS AND THEIR POTENTIAL TO ADSORB ARSENIC AND CADMIUMNorazlina Abu Sari, Che Fauziah Ishak, Rosenani Abu BakarBiochar as a new soil amendment has a potential in controlling the fate of trace elements in the soil system. However, the production of biochar from different feedstocks and pyrolysis conditions resulted in variable biochar properties which have an influence on trace elements availability. The experimental works are focused on physical and chemical properties of biochars produced from Empty Fruit … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 13 Aug 2014 · 10,585 accessesView PDFCite
