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...

investigations have been carried out on the indoor air pollution in .different workshops of food processing plants in iran. in order to evaluate the exposure of workers to the three most commonly used indices of air pollution ten food processing plants representing ten groups of food industry with 2.816 workers were selected. air borne contamination of different origins such cotton seed. barley...

background some human diseases such as tuberculosis, legionnaires' disease and different forms of bacterial pneumonia, coccidioidomycosis, influenza, measles, and gastrointestinal illnesses are the result of exposure to bioaerosols. in addition, they are associated with some noninfectious airway diseases, such as allergies and asthma. objectives in the education hospitals of hamedan university ...

Milimeter Wave (mmWave) is a solution to overcome of frequency limitations in 5G technology implementations using high frequency carrier domain. This research discusses about mmWave frequency selection for 5G technology using empirical methods for indoor propagation model. Several mmWave frequencies are simulated on indoor office environment. Based on simulation with Indoor Hotspot (InH) placed...

This study presents indoor/outdoor PM2.5 and PM10 concentrations measured during winter and summer in 15 homes in Kocaeli, which is one of the most industrialized areas in Turkey. Indoor and outdoor PM2.5 and PM10 mass concentrations and elemental composition were determined using an X-ray fluorescence spectrometer. Quantitative information was obtained on mass concentrations and other characte...

background: the effect of mold fungi to allergic sensitization is not well-known. we aimed to evaluate the role of molds in the relation between indoor environment and atopy in asthmatics. materials and methods:the air samples obtained from 66 stable asthmaticsand 35 control subject’shouses were sprayed into sabouraud dextrose agar. allergy skin testing were performed both groups. the tempera...

Indoor air pollution caused by the indoor burning of solid biomass fuels has been associated with Acute Respiratory Infections such as pneumonia amongst children of less than five years of age. Behavioural change interventions have been identified as a potential strategy to reduce child indoor air pollution exposure, yet very little is known about the impact of behavioural change interventions ...

Current increase of atmospheric air pollution rates in developing and developed countries requires efforts to design more cost effective and affordable devices. In developed countries pollution monitoring chambers are available to aid the monitoring process. The culture and the society are aware of the polluted environment side effects and measures have been taken to reduce pollution amounts. M...

There has been discrepancies between the daily air quality reports of the Beijing municipal government, observations recorded at the U.S. Embassy in Beijing, and Beijing residents' perceptions of air quality. This study estimates Beijing's daily area PM(2.5) mass concentration by means of a novel technique SPA (Single Point Areal Estimation) that uses data from the single PM(2.5) observation st...

There has been a tendency throughout Latin America, in recent decades of the expansion of activities associated with reprimarization. The latter refers to all activities of extractivism, such as mining and petroleum, as well as agricultural activities, such as cattle and soy. These are linked to the strong growth of the commodities markets and the amazing growth of China. This paper examines th...
