disasters are one of the most important challenges which must be considered by every management system. higher education centers have high disaster risk because of their risk factors (existence of historical and scientific documents and resources and expensive laboratory equipment in these centers emphasizes the importance of disaster management). moreover, the existence of young volunteers of ...
weather and climate have considerable influence on the concentration of air pollutants such as particles and gases. the range and concentration of these particles and gases are very dependent on prevailing weather conditions and air currents. this research concentrates on health effects of benzene, one of the air pollutants of tehran, as a major city. the concentration of benzene emission to ai...
background: in the current study,the hazard quotient, the hazard index (hi) and spatial variations of fe,mn,cu and cr in drinking water sources of andimesk-shush, khuzestan province, southern iranaquifer were assessed. methods: we compared theconcentrations of aforementioned heavy metals in wells and springs inandimeshk and shush regions. the non-carcinogenic risk assessment of heavy metals was...
background: the aim of this study was assessment the risk management status of waste anesthetic gases in academicals hospitals in iran to prevent from harmful effects of these gases on employees' health. methods: a descriptive-analytic study was designed in 2011. standard structured checklist developed by ecri institute (emergency care research institute) was applied. checklists were filled ons...
background: chemical contaminants present in the work environments include gases, vapors, and solid and liquid suspended particles. the number of factories producing chemicals has increased significantly. each year, new products are introduced into the market. consequently, the number of employees at risk of exposure to these materials is increased. hazardous chemicals are used in the petrochem...
To avoid over-reliance on the identification of building damage states post-earthquake in seismic risk assessment process, an ontology-based holistic and probabilistic framework is proposed here for prediction buildings with various purposes different states. Based vulnerability analysis, probabilities are first obtained by considering on-site hazard. Taking economic losses casualties as indica...
