[ 1 ] - پیش‌بینی شاخص کیفیت هوا برمبنای متغیرهای هواشناسی و مولفه‌های خودهمبسته با استفاده از شبکه عصبی مصنوعی
Background: Air Quality Index (AQI) quantifies the relationship between air quality and the level of health. The value of AQI may be predicted using neural network model for a day in advance, based on the meteorological variables and autocorrelation behavior of the index in Kermanshah, a city in western Iran. Methods: Data for air pollution and meteorological variables, collected during thre...
[ 2 ] - کارایی تصفیه خانه متداول فاضلاب در حذف آنتی بیوتیک و تعیین غلظت آن، تصفیه خانه فاضلاب اکباتان و جنوب تهران: مطالعه موردی
Background and Objective: Antibiotics are a group of emerging contaminants in the aquatic environment. Antibiotic residues threaten the human health and ecosystem in the low concentrations found in the environment. Hence, the present work has been conducted to investigate the occurrence and removal efficiency of most prescribed antibiotics including amoxicillin, penicillin, cefixime, cephalexin...
[ 3 ] - ارزیابی ریسک سرطانزایی و نسبت خطر غیر‌سرطانزایی کروم درآب‌های آشامیدنی بطری شده در ایران
Background and Objective: Exposure to chemicals such as heavy metals can be occurred through the route of drinking water consumption. Chromium is an important pollutant because of its role in the appearance of carcinogenic and non-carcinogenic health effects in humans. In this study, we studied the carcinogenic risk and non-carcinogenic hazard of chromium due to the consumption of bottled drink...
[ 4 ] - تعیین آلودگی فلزات سمی به روش استخراج در 6 مارک ورمی کمپوست حاصل از پسماندهای آلی شهر تهران
Background and objective: Compost is beneficial for conditioning the structure and nutrient content of soil. Toxic metals are the most important contaminants that can enter the food chain through the compost products and affect human health. The aim of this study was to assess the arsenic, mercury, cadmium, and lead levels in six brands of vermicompost produced from the organic solid wastes in ...
[ 5 ] - عملکرد بیوراکتور تلفیقی ستون حباب مایع- بیوفیلتر در حذف دی‌کلرومتان از جریان‌های گازی آلوده
Background and objectives: Dichloromethane (DCM) is one of the hazardous contaminants of the environment, especially ambient air that threatens human health at both acute and chronic exposures. In this study, the performance of a pilot-scale hybrid bubble column/biofilter (HBCB) bioreactor was studied for the removal of DCM from waste gas streams at steady state. Materials and methods: The expe...
[ 6 ] - بررسی غلظت گاز رادن در هوای داخل منازل مسکونی و اماکن عمومی شهر فیروزکوه
Background and Objective: Radon is a radioactive, odorless gas. Radon gas with the emission of alpha radiation and sticking to aerosols in the air can cause lung cancer. This study evaluated the concentration of radon in residential houses and public places in Firuzkuh city and compared the values with the recommended international guidelines. Materials and Methods: Radon gas concentration was...
