Abstract
Abstract Background & Objectives: water treatment systems by reverse osmosis are treatment systems in consumer point. According to water quality in Bojnurd city and Consumers tend to use water treatment systems. This study was carried out for the evaluation of water treatment systems’ performance and compared with national standards. Method and Materials: This cross-sectional descriptive study was carried out using samples taken from the inlet and outlet water of plants during a seven-month period in winter until summer seasons of the year 2013. A total number of 66 samples taken from 6 plants were analyzed for water physical, chemical and microbial quality. Data were analyzed with SPPS 18 and presented with Kolmogorov–Smirnov and T-Test . Results: According to the results the percentage of physical and chemical parameters in treated water for hardness, Alkalinity, Fluoride, TDS, Turbidity, EC, chloride, Na, K, Nitrate, Sulfate and Phosphate were all in acceptable level except for Fluoride and Mg. The average concentration of residual chlorine= 0.64 mg/l and pH range = 7.68. T-Test for total parameters except Phosphate were P<0.05. 5.41% of samples were contaminated by Total Coliforms and all samples by Clostridium perfringens but no fecal coliforms. Heterotrophic bacteria were lower than standards. Conclusions: Continuous control and monitoring of the quality of inlet and outlet water in desalination plants is necessary.

Abstract
Abstract Background & Objectives Hospital wastewater due to containing many hazardous agents such as infective elements, pharmacy substances, chemical and radioactive agents has a special sensibility. So it is necessary to transfer, treatment and disposal the wastewater of medical centers. This survey aimed to determine wastewater pollution rate in order to achive an accurate planning requirement in bojnurd Materials & Methods in this cross-sectional study, wastewater quality of 3 hospitals was evaluated over a period of 5 months in the North khorasan Medical Sciences University in Bojnurd in 91-92. None of these hospitals had treatment plant. Samples were transferred to the chemistry lab. Then, BOD5, COD, TSS, pH, temperature and concentration of Amoxicillin were measured in the lab in 190 nm wavelenth. Results The results showed that, the higher average BOD5 and COD in Bentolhoda hospital wastewater over the other two, but the concentration of TSS in Imam Reza Hospital was highest.These findings could be justified on the grounds of the usage of Bentolhoda hospital (maternity). The avearges of pH of the studied hospitals were slightly alkaline which was suitable for biological processes. Amoxicilline concentration of hospitals Imam Ali, Imam Reza and Bentolhoda were 64.88 and 259.4 and 56.49 respectively Conclusion Our results showed all of these parameters are higher than its standard level. So it is necessary to have control on hospital wastewater treatment to prevent entrance of hazardous materials to municipal. Therefore, more researches and making positive attitude in related responsible to refine wastewater of these hospitals are suggested.

Abstract
Background & objectives: Inattention to management of medical wastes has environmental, occupational and public health hazards. Therefore this study aimed to determine the amount of hospital waste generated and status of waste management in hospitals of North Khorasan University of Medical Sciences in 2013 and to give a suitable framework for improving waste management practices. Materials and Methods: This descriptive-cross sectional study was performed in 6 active hospitals of North Khorasan University of Medical Sciences. Sampling was achieved in summer and autumn 2013 for 2 days in each season and by means of laboratory scale were measured. Data were collected using a checklist of environmental health protection of IRAN and for data analysis, SPSS18 (mean ± SD) and Excel software were used. Results: The average of total quantity of waste produced in all hospitals was about 1360 kg/day comprised of 56.54% of infectious waste, 41.49% general waste, 1.82% sharps waste and 0.15% chemical waste. Medical waste generation rate for total, general, infectious, sharp and chemical wastes were 2.64±1.31, 1.085±0.74, 1.493±0.65, 0.049±0.028 and 0.010±0.025 kg/bed-day, respectively. According to completed checklist of hospital waste management, 33.3% of studied hospitals were favorite, 50% tolerable and 16.7% unfavorable. Conclusion: According to this study, infectious wastes are the most generated waste. In order to reduce the amount of them, action should be taken to deal with pollutants at their source of generation and labeling, which could reduce the costs of hospital waste management and giving more accurate statistics. Effective segregation at the source, appropriate collection methods, safe storage and transportation of waste and control of waste disposal are recommended

Abstract
Background & Objectives: Toxoplasmosis is a disease parasite which can infect human and animals. Infection in human is usually asymptomatic. The infection may be serious if is transmitted to the fetus during pregnancy. The present study aimed to determine prevalence and factors associated with T. gondii infection in northern Khorasan, Iran.
Materials and Methods: The cross–sectional study 1302 Serum samples were collected from different cities of Northern Khorasan Province and tested for IgG, IgM and IgA antibodies against T. gondii using ELISA method. Overall, 1302 pregnant women during first trimester were recruited. The mean age was from 16 to 46 years of olds and data were analyzed using the SPSS version 22.
Results: From 1302 examined samples, 690, 40 and 57 samples were positive for IgG, IgM and IgA, respectively. In current work, there was not any significant difference between Toxoplasmosis and education level and use of row vegetables. But the differences between contact to cat and use of row meat and prevalences of toxoplasma gondii are significant.
Conclusion: The probability of T.gondii IgM and IgA contamination should seriously be considered during Pregnancy. Testing pregnant women for Toxoplasma gondii is suggested to be done routinely during pregnancy; especially in trimester.

Abstract
Introduction: Dental units are among the equipment that flows through the dental application, and due to the durability of water and the probability of forming the biofilm. They can have a high microbial load. It is important to investigate this pollution, which should be frequently investigated due to the incidence of dangerous infections in people with weakness of the defense system, pollution and dental units. The aim of this study is to investigate the amount of bacterial infection and pollutant of Water Supply in Dental units at Bojnourd dental school 2017. Methods: This study was conducted by descriptive _ analytical method on the water units in Bojnourd dental school.30 active units of the College of Dentistry were selected for the sampling. The samples were cultured on proprietary environments, and after 48 h at 37 ° C the number of microbial colonies was counted. And finally the obtained data were analyzed by SPSS 20.
Results: The results showed that the average total bacterial count before flushing and after flushing was 711 and 293 cfu / ml, respectively, which had the highest level of contamination in water before flushing.
Conclusions: The results of this study concluded that flushing was one of the best methods to reduce microbial contamination and Considering that dental units at Bojnourd dental school are polluted, dentists should pay more attention to prevent infection from infected patients and dental staff.
