Efficiency of a natural wetland for effluent polishing of a septic tank
Wetlands now days apply as a polishing system for the classical wastewater treatment, in addition of different usages. Usually wetland systems are inexpensive methods vs. expensive high technology treatment systems. Objective of this study is an evaluation of natural wetland treatment in polishing of a septic effluent. Research duration works extended for 10 months on a natural wetland system in Pardis of Mazandaran University of medical sciences and eastern north of health faculty.
A novel method for recovery of acidic sludge of used-motor oil reprocessing industries to bitumen using bentonite and SBS
Acidic sludge is a by-product from used motor oil reprocessing industries, which thousand tons of this sludge are disposed into the environment as a hazardous waste material daily. The acidic sludge contains unsaturated compounds that are polar and asphaltene. The bitumen under certain conditions is produced from mixing of bentonite, polymer styrene – butadiene – styrene (SBS), and acidic sludge.
Significance of authenticity in meat and meat products in Iran
The Authenticity of meat products is very important for religious and health reasons in Iran. According to legislation in Iran, the consumption and importation of pork, horse, donkey and cat products should be banned. Therefore, the identification of meat products cannot be judged solely by its appearance.
Nonthermal Effects of Radar Exposure on Human: A Review Article
Microwave is part of the electromagnetic spectrum that has different application such as communications, military, air-traffic Control and etc... Previous studies showed that radar frequency could be a health hazard agent. This review article mentioned some of the studies that investigated non-thermal effects of radar frequencies.
Statistical screening of hexavalent chromium biosorption by Sargassum
توضیحات : IRANIAN JOURNAL OF HEALTH, SAFETY AND ENVIRONMENT VOL 1, NO 1, 2014 writers: Abbas Rezaee, Hoshyar Hossini, Seyedomid Rastegar Abstract: The aim of this study was to investigate the statistical screening of hexavalent chromium, Cr (VI), from an aqueous solution using brown seaweed Sargassum as a biosorbent. The biosorption process […]
Occupational Noise Pollution and Hearing protection in selected industries
The use of technology in industries is ever increasing. With the introduction of this technology come new safety and human performance concerns. Hearing loss caused by industrial noise has been recognized for many years, and protection of employee hearing has been made mandatory by governmental agencies. This paper presents an investigation of occupational noise exposure and Personal hearing protective devices (PHPD) in selected industries in the south-eastern Iran.
The Prevalence of Needle sticks injuries among health care workers at a hospital in Tehran
Needle stick injuries (NSIs) are one of the most significant and preventable hazards in relation to Healthcare workers (HCWs). Such injuries have been shown to be of high prevalence within developing countries. To determine the prevalence and circumstances pertaining to the occurrence of NSIs among HCWs employed at a special hospital.
Optimization of pyrene removal from contaminated soil by electrokinetic remediation process
The electrokinetic remediation process has been intensively investigated by many researchers as a novel technique to remove different pollutants from soil. The process utilizes a direct-current electric field to soils to insert some process such as electroosmosis and electrolytic migration. In the present study, the removal of pyrene as a model of polycyclic aromatic hydrocarbons (PAHs) were optimized using response surface methodology (RSM) based on central composite design (CCD).
Influence of pollution loading and flow rate on catalytic BTEX removal with a combined Cu2O, Fe0/Zeolite bed
Environmental impacts and health concerns of BTEX compounds have been pointed in many studies. The agencies responsible for health and environment have delivered standard and guideline for BTEX concentrations. Because of the extensive use in industries and the presence of these compounds in fossil fuels, their emission resources are very divers.
The survey of electrocoagulation Process for removal dye Reactive Orange 16 from aqueous solutions using sacrificial iron electrodes
Discharge of textile industries colored wastewaters without enough treatment into natural water supplies cause serious damages to the environment. This study was performed to investigate the effect of electrocoagulation for dye removal from synthetic wastewater using iron electrodes.
