Environmental pollution is one of the serious crisis to which we are facing today. It is fact that three basic elements air, water and land which constitute harmony of nature for proper and balance living of all organisms, it was fortunate enough that such hospitable and balance environment was the destiny of our predecessors. But it is contrary to living of the present environment. With the ra...

Environmental tobacco smoke (ETS) is a major contributor to indoor air pollution. Since decades it is well documented that ETS can be harmful to human health and causes premature death and disease. In comparison to the huge research on toxicological substances of ETS, less attention was paid on the concentration of indoor ETS-dependent particulate matter (PM). Especially, investigation that foc...

abstract background and purpose: people are always exposed to ionizing radiation, which could badly influence their health. the degree of these influences depends on the level of radiations. in this study the dose of indoor gamma radiation was assessed using rds-110 multi-purpose survey meter. materials and methods: to determine the dose rate of indoor radiations in cities of hamedan province f...

Fine particles are associated with hundreds of thousands annual deaths and significant increase in morbidity in Europe. Improvement of air quality and reduction of air pollution emissions are identified as the primary goals, but environmental policies can be targeted in different ways. It is clear, that optimal protection of public health is achieved by policy options reducing population exposu...

Water and sanitation in hospitals are a serious forgotten issue. Water quality impacts the performance of the hospitals and its deterioration leads to drastic health service deterioration affecting infection control programs, occupational health and safety of the workers as well as the safety of the hospital buildings and its anticipated life service. The integrated environmental management in ...

indoor air quality is a general concept that specifies to air quality of buildings and is related to health and relaxation in there. this index contains removal of all contaminants for example microbial, gas types, particles, etc., and suggests remedial approaches toward refreshing the building air and air circulation in these constructions. in this article we study indoor air quality index (ia...

Bioaerosols produced by dental procedures may affect indoor air quality and cause infections in dental healthcare workers. To provide air quality data that can be used to protect dental healthcare workers, this study evaluated the air quality and its influencing factors in the dental department of the Chang Gung Memorial Hospital in Taiwan. The study was a cross-sectional study design. Indoor a...

The salaries of office workers are many times higher than the cost of operating a building in developed countries (Woods, 1989; Seppänen, 1999). Consequently, even small improvements in human performance and productivity following improvements of indoor environmental quality (IEQ) can result in a substantial economic benefit. Based on very conservative assumptions, Fisk and Rosenfeld (1997) est...

his article, a summary of Fisk,1,2 estimates the nationwide improvements in health and productivity potentially attainable by providing better indoor environmental quality (IEQ) in U.S. buildings. Estimates include the potential reductions in three categories of health effects, the associated economic benefits, and the potential direct improvements in productivity not mediated through health.

Environmental carcinogens, in a strict sense, include outdoor and indoor air pollutants, as well as soil and drinking water contaminants. An increased risk of mesothelioma has consistently been detected among individuals experiencing residential exposure to asbestos, whereas results for lung cancer are less consistent. At least 14 good-quality studies have investigated lung cancer risk from out...
