background and aims: Hospital acoustics, noisy equipment and people have adversely impacts on patient’s physical and mental health. This paper aims to identify the major sources of noise and noise control techniques in hospitals of Behbahan Methods: Noise measurement was done according to ISO9612 at designated stations. Equivalent sound pressure levels were measured at 243...

Redistributive objectives influence the optimal provision of a pure public good— such as air quality— only if costless transfers are not available. In an urban program, the emphasis in the control strategy will shift somewhat toward goods and services consumed predominantly by the wealthier, such as transportation services, vehicles and fuels. If instruments affect rural areas as well, optimal ...
Background and purpose: Air pollution is one of the most important environmental factors threatening human health that cause short and long term health effects and various diseases. The present study aimed at investigating and quantifying the health consequences associated with exposure to O3, NO2, and SO2 in ambient air in Tehran, 2014, using the air quality (Air Q) model. Materials and met...
Environmental pollution control is one of the most important goals in pollution risk assessment today. In this sense, modern and precise tools that allow scientists to evaluate, quantify and predict air pollution are of particular interest. Monitoring atmospheric particulate matter is a challenge faced by the European Union. Specific rules on this subject are being developed (Directive 2004/107...
Although official efforts to control air pollution have traditionally focused on outdoor air, it is now apparent that elevated contaminant concentrations are common inside some private and public buildings. Concerns about potential public health problems due to indoor air pollution are based on evidence that urban residents typically spend more than 90 percent of their time indoors, concentrati...
OBJECTIVES Air pollution exposure induces cardiovascular effects, possibly via systemic inflammation and coagulation misbalance. Genetic variation may determine individual susceptibility. Our aim was to investigate effect modification by inflammation (Interleukin6 (IL6), tumour necrosis factor-α (TNF-α)) and coagulation (fibrinogen Bβ, plasminogen activator inhibitor-1 (PAI-1)) gene variants on...

air pollution is the most important environmental problem of last century that threatens the health of living organisms, especially plants. so2 is one of the main air pollutants that can cause to imbalance in growth and physiological function of plant in high concentrations. symbiosis of rhizobium bacteria with alfalfa can cause increasing plant growth and plant resistance to abiotic stresses. ...
