Events leading up to the release of toxic chemicals in the processing plants are one of the main hazards of chemical industries that can endanger employees and also people in neighborhood. In this study, DOW's Chemical Exposure Index (CEI) is used to determine hazard distances of possible toxic chemical releases in one of the South Pars gas refineries. To...
acquired bilateral longitudinal true leukonychia is a rare disorder. we present a case of a 35‑year‑old healthy woman presented with this unusual and rare manifestation. she mentioned a history of unprotected exposure to detergents and bleaching chemical agents. considering her low zinc level, she was prescribed with zinc capsules and recommended to avoid chemical substances for 6 months. durin...
The particular substances that are ingested by individuals are the consequence of their environmental, residential, and occupational exposures. The possible effects of these exposures on intestinal functions can be examined by the evaluation of in vivo or in vitro exposure followed by an in vivo and/or in vitro monitoring of effects. Several examples of the in vivo exposure and in vitro monitor...
Workers are commonly exposed to multiple factors and substances that are hazardous to health. For instance, in 2005, approximately 30% of the European workers reported being exposed to noise during at least a quarter of the time spent in their work environment, 11% reported inhaling vapors such as solvents and thinners; 19% reported exposure to smoke, fumes, powder, or dust; and 14% reported ha...
Background and Objective: Sulfur mustard is a potent chemical vesicant warfare agent that remains a significant military and civilian threat. Inhalation of sulfur mustard gas causes inflammation and injury to airways and bronchioles. Mast cells promote allergic reactions when exposed to some chemical compounds such as HD. Hexamethylenetetramine has been shown to protect human lung cells against...
background: the use of chemicals is essential in education resulting in exposure to these pollutant in a variety of chemical and research laboratories. chemical contaminants in chemical laboratories are in different forms and chemical exposure risk assessment is important for choosing appropriate controls in protecting the health of operators, experts and students. for risk assessment in chemic...
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis , a one- way anova experimental design was carried out. 24 senior student of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inte...
Background and aims: The chemical pollution in industries has make an unacceptable risk for the human health. For the risk assessment of the human exposure, it is necessary to be considered the material dangers based on the consumption rate, dose, toxic properties, and evaluation of potential effects on the human health. Therefore, the aim of this study was to assess the semi-quantitative risk ...
