Abstract
Background : In the educational hospitals of Hamedan university of medical sciences there was no previous study on qualitative and quantitative of bioaerosoles in the air of different wards. So, in this study the quality and quantity of bioaerosols in the air of hospitals was investigated to establish reference for future studies or measures.
Materials and Methods: In this cross sectional research, 30 wards from 5 educational hospitals of Hamedan city were studied. More than 180 air samples were collected in the various locations and conditions according to filtration method suggested by bioaerosol committee of ACGIH. The samples were transported to blood agar and sabouraud medium then were cultivated immediately. The type and number of colonies were determined in the laboratory then, the bioaerosol concentration was calculated in terms of cfu/m3. SPSS software was used for data management and related statistical analysis was carried out.
Results: There were highest and lowest concentration of bioaerosols in women1 and operating room wards of Fatemiyeh hospital, respectively (54.4cfu/m3 vs. 13.3cfu/m3). It was appeared that there was no significant correlation between concentration of bioaerosols in the hospitals and proposed standard level (P=0.3). The highest fungal population were Penicelium (32.06%), Cladosporium (20.5%), Aspergillus fumigates (14.61%), Aspergillus niiger (7.43%), respectively. The highest bacterial population were coagulase-negative staphylococci (32.49%), Bacillus spp. (14.74%), Micrococcus spp.(13.68%) and Staphylococcus aureus (11.34%), respectively.
Conclusion: Quantitative bioaresols concentration in the air of some hospitals was more than proposed standard. Most surveyed hospitals lacked air treatment systems so, for reducing bioaerosol concentration, standard ventilation system should be designed and utilized.

Abstract
Background : Rivers are a fraction of flowing waters in the worlds and one of the important sources of water for different consumptions such as agricultural, drinking and industrial uses. The aim of this study was to assess water quality of the Khorramrood River in Khorramabad by NSFWQI index. Materials and Methods: In this cross-sectional study, quality parameters needed for NASWQI index calculation such as BOD5, dissolved oxygen (DO), total nitrate, fecal coliform, pH, total phosphate, temperature, turbidity and total suspended solids content were measured for six months (from July to December 2012)using standard methods at six selected stations. The river zoning conducted by GIS software. Results: According to the results obtained through this study, the highest and the lowest water quality value was observed in stations 1 and 6 with NSFWQI indexes 82 water with good quality, 42 water with bad quality, respectively. With moving toward last station (from 1 to 6 station) water pollution increased. Conclusion: Results of the study indicated that water quality index NSFWQI is a good index to identify the effect of polluter sources on the river water. Based on the average of the index NSFWQI, water quality in station one was good, in the second, third and fourth stations were mediocre and the fifth and sixth stations had bad quality. These results allow to make decisions about monitoring and controlling water pollution sources, as well as provide different efficient uses of it by relevant authorities.
