Heavy metal concentration of soils affected by Zn-smelter activities in the Qeshm Island, Iran
In this study, concentrations of heavy metals in soils around a Zn-smelter in Qeshm island, Iran, are investigated. Calculated geoaccumulation index (Igeo), contamination factor (Cf), and contamination degree (Cdeg) values indicate surface soil contamination by toxic metals (As, Cd, Pb, and Zn). The results also indicate that most contaminated areas are located in the vicinity of the smelter an...
متن کاملthe effects of keyword and context methods on pronunciation and receptive/ productive vocabulary of low-intermediate iranian efl learners: short-term and long-term memory in focus
از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
15 صفحه اولmicrobial community structure and diversity in long-term hydrocarbon and heavy metal contaminated soils
the influence of long-term mixed organic and inorganic contamination on soil microbial activity, community structure and genetic diversity was investigated in soil samples from a coke oven plant located in upper silesia, poland. the tested soils were heavily contaminated with polycyclic aromatic hydrocarbons (pahs) and heavy metals. the microbial communities were characterized using the phospho...
متن کاملColonization of heavy metal-polluted soils by Collembola: preliminary experiments in compartmented boxes
9 10 Two-week laboratory experiments were carried out in plastic boxes separated in two connected 11 compartments filled with a neutral soil (mull humus) at pH 7.7 and an acid soil (moder humus) at pH 12 4.3, containing their original faunas. Migration of Collembola from one compartment to the other was 13 allowed through a perforated wall. The mull was contaminated with three concentrations of...
