[ 1 ] - حذف آنتی بیوتیک پنی‌سیلین جی از محیط های آبی با استفاده از راکتور ناپیوسته نانوذرات آهن صفر و فرایند ازن زنی
اهداف: آنتی‌بیوتیک‌ها به‌طور مؤثر با تصفیة متداول فاضلاب حذف نمی‌شود. آهن با ظرفیت صفر (nZVI) بازده بالا در تجزیة آلاینده‌هایی مانند فلزات سنگین، ترکیبات نیتروآروماتیک و حشره‌کش‌ها دارد. ازن‌زنی یکی از شناخته‌شده‌ترین روش‌های مؤثر در حذف مواد شیمیایی مقاوم به تجزیه مانند آنتی‌بیوتیک‌ها از آب و فاضلاب است. مواد و روش‌ها: این مطالعه از نوع تجربی است. برای حذف پنی‌سیلین جی، از نانو ذرات آهن صفر د...
[ 2 ] - بررسی کارایی فرآیند سونونانوکاتالیستی با استفاده از نانو ذرات دی‌اکسید تیتانیوم در حذف آنتی بیوتیک اریترومایسین و مترونیدازول از محیط های آبی
Background and purpose: Antibiotics are non-biodegradable and wastewater treatment processes are not fully effective in their removal. Therefore, presence of some antibiotics such as erythromycin and metronidazole in environment has become a major concern in recent years. The aim of this study was to evaluate TiO2 nano-particles for removal of these two antibiotics from aqueous solution based o...
[ 3 ] - ارزیابی ریسک غیرسرطان‌زایی فلزات سنگین جیوه و مس در گرد و غبار سطحی خیابان‌های شهر زاهدان
Background and Objective: Street dust is an important factor in urban pollution which consists of soil, particulate matters and heavy metals. At present, over half of the world’s population lives in urban areas. Therefore, this study aimed to investigate health risks of heavy metals in street dusts in Zahedan. Materials and Methods: The samples of street dust were collected in Zahedan. After p...
[ 4 ] - بررسی کارایی مزوپور سیلیکا متخلخل در حذف آنتی‌بیوتیک سفالکسین از محیط‌های آبی به روش سطح-پاسخ
Background and Objective: Extreme use of antibiotics and discharging to the environment lead to serious consequences. Mesoporous silica such as MCM-41 material is widely used to absorb contaminants from the aqueous solution. The aim of this study was to evaluate mesoporous synthesis of MCM-41 and its efficacy for removal of the antibiotic cephalexin from aqueous solution. Materials and Methods...
[ 5 ] - Survey of Water Quality of Mashkyd Dam Lake in Sib Suran City Using National Sanitation Foundation Water Quality Index (NSFWQI) and Iran Water Quality Index for Surface Water Resources-Conventional Parameters (IRWQISC)
Background & Aim: Water is an important and vital factor for human activity and is considered as one of the most important sources for development of countries. Due to the issues related to the water quality, this study was performed based on the two indices in order to evaluate the water quality and to take effective strategies for water consumption. Methods: This descriptive cross-sectiona...
[ 6 ] - Photocatalytic process using magnesium oxide nanoparticles for amoxicillin removal from aqueous solution
Background & Aim: Excessive consumption of antibiotics and their incomplete metabolization in human and animals, as well as inadequate removal by conventional waste water system leads to the release of these chemicals into the environment. Antibiotics have adverse effects including bacterial resistance, digestive disorders and genotoxic. Therefore the aim of this study was to survey amoxicillin...
[ 7 ] - Survey of surface runoff quality in Zahedan for irrigation usage
Background & Aim: Urban runoff is one of the most valuable and renewable water resources in many arid and semi-arid parts of the world. Understanding how to use these resources is very important. The purpose of this study was to determine the physical, chemical and biological properties of surface runoff in Zahedan for irrigation uses. Methods: The present work was a descriptive cross-sectiona...
[ 8 ] - Non-cancer Risk Assessment of Nitrate in Drinking Water of Urban and Rural areas of Zahedan City in 2018
Background & Aim: Groundwater is a major source of drinking water in Zahedan city; however, its quality is affected by high human activities and leads to the increased level of nitrate. This study was conducted to evaluate the nitrate concentration in water resources compared to the standards and also evaluating its Non-Carcinogenic Risk (Hazard Quotient: HQ) in Zahedan city. Methods: In this ...
[ 9 ] - Measurement of particulate matter concentration from dust storms and its relationship with interleukin 6 in healthy individuals in Zahedan
Background & Aim: Dust storms have detrimental effects on human health, the environment and the economy. Epidemiological research shows an association between air pollution and increased mortality from cardiovascular complications. Interleukins play key roles in production of inflammatory responses. The aim of this study was to determine the relationship between PM10 and interleukin 6 in health...
[ 10 ] - Trend of ambient air particulate matter with aerodynamic diameter of 2.5 μm and smaller in Zahedan city in 2018-2019
Background and Objective: Air pollution is one of the most important environmental risk factors that exposure to it can cause many acute and chronic effects on human health. Some regions of Iran, especially the western, southern and southeastern provinces of the country, have been affected with dust storm for years. Studies on the frequencies of dusty days in the country show that central pits ...
[ 11 ] - Photocatalytic removal of the antibiotic Ciprofloxacin from aqueous solutions using Fe-dopedTiO2@Fe3O4 magnetic nanoparticles
