[ 1 ] - A comparative study of the environmental health and safety of urban and rural schools of Abadan and their compliance with national standards
Students’ academic achievement as the community capital depends on the appropriate educational, physical, and psychological environment. Since students spend 20% of their time at school, and due to their high vulnerability to health problems and their value for the family, attention and promotion of their educational environment health is essential. A descriptive cross-sectional study was condu...
[ 2 ] - A survey on the knowledge and attitudes of Dehloran health network personnel about food safety and health
Controlling and ensuring the safety of food plays an important role in preventing foodborne illness. The major objective of this descriptive cross-sectional study was determined the food safety knowledge and attitudes of Dehloran Health Network personnel using a self-completed questionnaire. This structured questionnaire contains personal information, knowledge, and attitude questions. A total ...
[ 3 ] - Coupling adsorption by NiO nanopowder with UV/H2O2 process for Cr(VI) removal
Chromium enters surface and ground waters through the wastewater of electroplating, textile, metallurgical, dye production, and other industries, leading to numerous adverse health effects. The potential property of nanoparticle adsorption of nickel oxide (NiO) and the economic nature of ultraviolet/hydrogen peroxide (UV/H2O2) process have eased the usage of these two proc...
[ 4 ] - Assessment of DMFT and its influencing factors in guidance school students in Pirnshahr city, Iran
DMFT index is one of the best dental epidemiological indices, which represent the oral health status of the population and has been accepted by authorities and international organizations such as the World Health Organization. The aim of this study was to assess the permanent teeth DMFT index in guidance school students to determine the influencing factors such as brushing, tea and sugar consum...
[ 5 ] - Geographic Information System for distribution of groundwater fluoride levels in Iranian city of Dehloran
Humans are faced with serious problems due to the unfit fluoride levels in potable water, which cause skeletal and dental fluorosis. Therefore, correct information regarding fluoride level in water resources is important in community dentistry, however this data is missing at national level. The aim of this descriptive-analytical study was to explore and map fluoride dispersion patterns of grou...
[ 6 ] - Industrial landfill site selection using Analytical Hierarchy Process (Case study: Razi industrial town of Isfahan-Iran)
Suitable landfill site selection is a significant step in the integrated management of solid waste. Because of some dangerous industrial waste, landfill site selection is more important. The selection process should be considered different criteria. The purpose of this study was to determine the appropriate location of industrial waste landfill Razi complex by using Analytical Hierarchy Process...
[ 7 ] - Distribution of groundwater nitrate in Dehloran, Iran: A case study using GIS
Nitrate has been the most common chemical contaminant in water resource. This ion is introduced into the water via different ways, but more items of nitrate pollution was connected with farming-based drainage and sewage effluent. In this descriptive-analytical study, groundwater nitrate and nitrite concentrations of 8 wells on Dehloran, Ilam, Iran, were analyzed in 2015 to determine the causes ...
[ 8 ] - Simultaneous degradation and adsorption of cyanide using modified fly ASH and TiO2/UV
Due to the present water shortage and environmental problems associated with industrial effluent, investigation of novel treatment technologies is an essential approach. Being a highly toxic chemical of asphyxiating characteristics, cyanide is seen as a major environmental pollutant in a wide range of industrial effluents. The present study aimed to address the adsorption and photocatalytic deg...
[ 9 ] - Photocatalytic removal of o-chlorophenol by Using a Mixture of Modified Fly Ash and TiO2 Nanoparticles
Abstract Background: Photocatalytic process is used as a suitable method for o-chlorophenol removal. In this study, the efficiency of a mixture of modified fly ash and TiO2 nanoparticles in photocatalytic removal of o-chlorophenol was evaluated. Methods: After acid washing of fly ash, the absorbent was oxidized with potassium permanganate. ...
[ 10 ] - حذف فتوکاتالیستی ارتوکلروفنل از محلول‌های آبی با استفاده از مخلوط خاکستر فرار اصلاح شده - دی اکسید تیتانیم
فرایند فتوکاتالیستی به‌عنوان یکی از روش‌های مناسب در حذف ترکیبات فنلی استفاده می‌شود. در این مطالعه از مخلوط خاکستر فرار اصلاح شده دی اکسید تیتانیم برای افزایش راندمان حذف فتوکاتالیستی ارتوکلروفنل استفاده شد. این پژوهش تجربی در شش ماهه اول 1392 در مرکز تحقیقات مهندسی بهداشت محیط دانشگاه علوم پزشکی کرمان انجام گرفت. خاکستر فرار تهیه شده از نیروگاه برق حرارتی زرند کرمان ابتدا با اسید سولفوریک شست...
[ 11 ] - حذف رنگ متیلن‌بلو از محیط‌های آبی به‌وسیله خاکستر فرار فعال شده نیروگاه زرند کرمان
جذب سطحی از مهم‌ترین فرایندهای تصفیه فاضلاب‌های حاوی رنگ است. در این پژوهش چگونگی حذف رنگ متیلن‌بلو به‌عنوان یک رنگ شاخص، توسط جاذب خاکستر فرار فعال شده نیروگاه برق شهرستان زرند بررسی شد. خاکستر فرار نیروگاه زرند کرمان با استفاده از فرمالدئید در محیط اسیدی فعال شد و به‌عنوان جاذب، مورد استفاده قرار گرفت. عوامل مؤثر در فرایند فعال‌سازی جاذب شامل دما، زمان، مقدار فرمالدئید، مقدار و غلظت اسید و هم...
