Comparison of the Level of Cadmium and Lead between the Cigarette Filters of Different Iranian and non-Iranian Brands
Background: Cigarette butts have been shown to release numerous kinds of chemicals such as heavy metals in water and may be a continual source of aquatic environments contamination after discarding. The objective of the present study was to determine the concentration of Cd and Pb in cigarette filters of different Iranian and non-Iranian brands in smoked and non-smoked samples. Methods: Ten d...
متن کاملStaining Beverages and Cigarette Smoke on Composite Resin and Human Tooth Fluorescence by Direct Spectrometry.
INTRODUCTION This study evaluated the fluorescence intensity (FI) of different brands of composite resins (CRs) and compare those values with the FI of human tooth, under the action of cigarette smoke (CI), coffee (CA), and soft drink (CO), measured by direct spectrometry. MATERIALS AND METHODS A total of 30 specimens of each brand (Filtek Z350, Esthet-X, Amelogen, Durafill) were made. Others...

هدف اصلی این تحقیق مقایسه و تمایز بین روشها و استراتژیهای خاص برای درک مطلب بهتر در زبان مادری و زبان دوم بوده است. در قدم اول میزان توانایی افراد در درک مطلب فارسی و انگلیسی اندازه گیری و سپس رده بندی شد. همچنین از دانش آموزان خواسته شد که در مورد روشها و استراتژیهایی که برای درک مطلب بهتر به کار برده بودند توضیح دهند. نتیجه این مرحله از تحقیق نشان داد که دانشجویان برای درک مطلب مطلوب در زبان ...
15 صفحه اولCadmium accumulation and detoxification by alveolar macrophages of cigarette smokers.
STUDY OBJECTIVES Cadmium (Cd) is a toxic metal associated with emphysema and lung cancer, which is present in both air pollution and cigarette smoke. Metallothionein (MT) is an inducible protein that binds and detoxifies cellular Cd. The goals of this study were to determine whether increased concentrations of Cd are present in alveolar macrophages (AMs) of cigarette smokers (CSMs) and to deter...
متن کاملLandfill Leachate Monitoring: Applications of Stable Isotopes
The most significant impact of a landfill on the surrounding environment has been consistently identified as arising from the leachate (Farquhar 1989; CAE 1992; Mulvey 1997). Therefore, environmental monitoring programmes for landfills tend to focus on the detection of leachate impacts, particularly any contamination of ground and surface water (Lee and Jones 1991; DCC 1994). Conventional monit...
