[ 1 ] - بررسی امکان حذف اسید هیومیک با نمک‌های آهن و آلومینیوم از منابع آبی در شرایط انعقاد متداول
Background & Aims: Humic acid is a major agent in trihalomethanes (THMs) formation during chlorination process, which are known as carcinogens. The aim of this study were to investigate the removal of humic acid by three coagulants including PACl, alum and ferric chloride from water sources and their effect on zeta potencial. Materials & Methods: This study was conducted  ...
[ 2 ] - بررسی روند تغییرات غلظت بنزن و تولوئن در هوای شهر یزد و پهنه بندی با استفاده از سامانه سیستم اطلاعات جغرافیایی
Background and purpose: Today use of unleaded gasoline is increasing in the world which contain abundant amount of aromatic organic carcinogenic compounds. This study aimed at monitoring the temporal and spatial concentration of benzene and toluene as volatile organic compounds in ambient air in Yazd, Iran. Materials and methods: This research, was carried out in different hours of the morni...
[ 3 ] - برآورد شاخص کیفیت هوا و مخاطرات بهداشتی منتسب به PM10، PM2.5 و SO2 در هوای شهر یزد
Background and purpose: In the past two decades, epidemiological studies have shown that outdoor air pollution lead to increase in respiratory symptoms, cardiovascular diseases, chronic bronchitis and mortality. This study aimed to estimate AQI index and the risk of cardiovascular and respiratory diseases and premature mortality caused by PM10, PM2.5 and SO2 in Yazd, 2013-2014. Materials and...
[ 4 ] - تعیین شرایط بهینه حذف پیش‌سازهای محصولات ثانویه کلرینه از منابع آبی توسط نانوکربن فعال و نانوزئولیت با روش تاگوچی
زمینه و هدف: اسید هیومیک عامل اصلی تولید محصولات ثانویه کلرینه (CBPs) آب میباشد که سرطان زا هستند. هدف این مطالعه تعیین شرایط بهینه حذف اسید هیومیک توسط نانوکربن فعال و نانوزئولیتِ کلینوپتیلولایت اصلاح شده با سورفکتانت کاتیونی (SMNZ) ازآب ورودی تصفیه خانه باباشیخعلی اصفهان بود. روش کار: این مطالعه بصورت تجربی در مقیاس آزمایشگاهی در راکتور ناپیوسته انجام شد. نمونه های آب مورد نیاز از ورودی تصفیه...
[ 5 ] - تحلیل فضایی آلاینده‌های شاخص هوا و مرگ و میر منتسب در شهر اصفهان
Introduction and purpose: Long term exposure to air pollutants can result in the development and acceleration of various conditions, such as cardiac and respiratory problems, reduced lung function, chronic bronchitis, asthma, pulmonary cancer, and even death. Regarding this, the aim of the present study was to perform a spatial analysis of air pollution and mortality in Isfahan,...
[ 6 ] - بررسی روند تغییرات شاخص کیفیت بهداشتی هوا (AQI) در شهر مشهد با سامانه اظلاعات جغرافیایی (GIS)
Introduction and Purpose: Mashhad, one of the most populous cities in Iran, is facing air pollution due to motor vehicle emissions and industries. Therefore, this study aimed to evaluate the variations in Air Quality Index (AQI) during the spring of 2012-2014 and its spatial zoning with Arc GIS. Methods: In this descriptive study, the AQI values were calculated by the associ...
[ 7 ] - A Protocol for Pollution Index, Source Identification, and Spatial Analysis of Heavy Metals in Top Soil
Introduction: This study aimed to assess a good protocol for the contamination indexes, concentration, spatial analysis, and source identification of toxic metals in top soils. Materials and Methods: In the first step, samples were taken from top soil (30 cm) and the metals were extracted and detected with ICP-AES. In the second step, Enrichment Factor, Geoaccumulation Index, and Contamination...
[ 8 ] - Experimental Protocol for Detecting SARS-CoV-2 in Screenings and Grit Samples of Wastewater Treatment Plants
Introduction: Although various liquid, solid, and gaseous streams of wastewater treatment plants (WWTPs) have been analyzed in many studies for the presence of SARS-CoV-2 RNA, no study was found to sample and detect SARS-CoV-2 RNA in screenings and grit samples separated from primary treatment units of WWTP. Hence, this study aims to provide an experimental protocol for sampling and extracting ...
