[ 1 ] - Applicable risk assessment methods in occupational and environmental exposure to nanoparticles - a narrative review
Nanoparticles (NPs) are a heterogeneous group of materials that have various applications, and their risk assessment is an essential condition. This study aimed to review the applicable risk assessment methods in occupational and environmental exposures to NPs. A literature search for articles published since 2005 in Web of Knowledge, Scopus, PubMed, Science Direct, and Google Scholar, using ap...
[ 2 ] - طراحی و ارائه یک بسته نرم‌افزاری مبتنی بر روش Control Banding جهت ارزیابی ریسک مواجهه شغلی با نانومواد
Background and aims: The development of nanotechnology has result in the creation of new job opportunities and economic growth. But the lack of sufficient information about the toxicity and occupational exposure limits to nanomaterials on the toxicity and occupational exposure limits established nanomaterials always has created concerns. In this study design and providing of a simple software p...
[ 3 ] - بررسی آلودگی سطوح با داروهای سیکلوفسفامید و ایفسفامید در مراکز کموتراپی
Background and purpose: Cyclophosphamide and ifosfamide are two most widely used and hazardous drugs in chemotherapy centers. This study aimed at determining surface contamination with cyclophosphamide and iphosphamide in chemotherapy centers. Materials and methods: This descriptive cross-sectional study was carried out in three chemotherapy centers affiliated with Hamedan University o...
[ 4 ] - بررسی ارتباط بین غلظت تتراکلرواتیلن در هوای بازدم و سطوح مواجهه فردی در شاغلین خشکشویی
Background: When workplace air monitoring is not sufficient to determine the exposure levels, the determination of compounds and some metabolites in exhaled air and personal exposure levels is considered a practical method for biological monitoring. The aim of this study was to determine the relationship between the concentration of tetrachlorethylene in exhaled air and personal exposure levels...
[ 5 ] - بررسی ارتباط بین غلظت های محیطی و سطوح مواجهه فردی با فرمالدئید در بخش های پاتولوژی بیمارستانهای آموزشی دانشگاه علوم پزشکی همدان
Background: Formaldehyde used in the pathology and histology laboratories as a tissue fixation. Formaldehyde classified in group A1 (human carcinogen) by the International Agency for Research on Cancer (IARC). The aim of this study was the evaluation of relationship between ambient concentrations and time-weighted average or ceiling exposures of formaldehyde the pathology departments. Methods:...
[ 6 ] - ارزیابی پیامد حریق مخازن گاز متان در یک پالایشگاه گاز
Introduction: using fossil fuels, some hazards such as explosion and fire are probable. This study was aimed to consequence modeling of fire on Methane storage tanks in a gas refinery using analyzing the risk, and modeling and evaluating the related consequences. Method: Hazard analysis by PHA was used to choosing the worst-case scenario. Then, causes of the scenario were determined by FTA. ...
[ 7 ] - مروری بر روش‌ها و وسایل ارزیابی مواجهه شغلی با نانوذارت
Background & objective:: In recent years, there has been a dramatic increase in the application of nanotechnology in industries and the number of workers occupied in different processes of research on and construction, production and residue disposal of products containing nanoparticles. Despite this growth, however, there is still a dearth of information on the risk of occupational exposure to...
[ 8 ] - حذف بخار جیوه از هوای مطبهای دندان‌پزشکی با استفاده از یک سامانه پالایش گر مبتنی بر نانوذرات نقره
Background & objective: Mercury is a toxic and bio-accumulative pollutant that has adverse effects on environmental and human health. There have been a number of attempts to regulate mercury emissions tothe atmosphere. Silver nanoparticles are a number of materials that have highly potential to absorb mercury and formation of mercury amalgam.The aim of this study is removal of mercury va...
[ 9 ] - Application of Arc-GIS for zoning of occupational exposure levels to respirable crystalline silica in crushing factories
Introduction: The silica crushing is a process based on crushing, screening and, granulation of various types of silica rocks. The inhalation of silica dust leads to silicosis by causing irreversible fibrosis in lung tissue. The crystalline silica is classified as a human carcinogenic (group I) by the IARC. Azandarian region is one of the largest silica production units in Iran with 40 silica c...
