Introduction: Swimming pools are one of the most important sport and recreational areas where health tips must be followed, or adverse results would threaten the health of the whole society. Objective: The aim of this study was to identify and evaluate the health and hygienic status of the swimming pools as well as water health status in public pools in Mashhad in the first nine months of 2018. Methods: This practical research has been carried out to identify the relevant risks, as field observations for assessing the hygienic condition of indoor areas in 64 swimming pools For data collection in the present study, valid and reliable questionnaires of general information and human resources (14 question), health assessment (37 questions), and water quality control of Mashhad’s swimming pools were used. Parametric analysis of variance was utilized for normal data, and non-normal data were analyzed by Kruskal-Wallis nonparametric test by considering P <0.05. Results: The results of the evaluation of water quality by health centers indicated that the desirability amount of the residual chlorine, water pH, water temperature, water turbidity, microbial thermophile coliforms, heterotrophic bacteria, and water chemical quality was 86%, 96%, 95.44%, 92.44%, 96.49%, 94.96%, and 95.31%, respectively. Amount of the residual chlorine, water turbidity, and heterotrophic bacteria was below the expected level of 95%. The outcomes of the tests administered by Mashhad health and hygiene centers (supervision organization), and pool managers' self-control examinations revealed that the results of water pH, water temperature, thermophile coliform, and water chemical tests were in total accordance with standards (P <0.05). Conclusion: The results showed that most of the health risks were related to the residual chlorine, turbidity, and microbial contamination of water by heterotrophic bacteria. Training swimmers and hygiene culture development have a pivotal role in controlling health risks

Background and purpose:The bulk of the waste of our country is considered to be corrupt.Compost is the best option for managing this waste component.That's why a lot of compost industries have been built in the country.Produced fertilizer compost should be in accordance with standards,so that it can be used to improve soil quality;Therefore,the purpose of this study was to study the physical,chemical and biological properties of compost manure produced by compost industries in Mazandaran,Golestan and Guilan provinces in 2016 and compare them with standards. Materials and methods:This study is a descriptive-analytic study.Sampling and analysis of physical,chemical and biological parameters; Once a month during the 3 months of spring.Data were analyzed using SPSS16 statistical software. Results:The results showed that pH, particulate matter, phosphorus,percentage of foreign matter and heavy metals in Babol,Rasht and Aq Qala samplers were lower than standard standards of Iran,WHO and Guttos theory.In terms of moisture and C/N it is compost grade 2.For example,in terms of carbon dioxide,organic matter and nitrogen are in the compass grade I and Iran's Gotthes theory and are acceptable.In terms of fecal coliforms and Salmonella in Class A, it is considered to be in Class B leech seed. Conclusion:This study showed that the quality of compost produced is in grade 2 and therefore, in order to achieve grade 1 compost,measures such as separation at source and more principled utilization of the fertilization process are needed.
