Background & Objective: Public swimming pools are susceptible places for the spread and transmission of pathogenic fungi. This study aims to determine fungal contamination in the environment and water of swimming pools and its relationship with the water chlorine level, temperature, pH and turbidity, to promote the public health system. Materials & Methods: Water samples were collected from 13 ...
Background: Infections are readily transmitted as a result of bacterial contamination of swimming pools. Therefore, hygiene and preventing the contamination of swimming pools is of particular importance. The objective of this study was to determine the amount of bacterial contamination in indoor pools of Yazd in 2013. Methods: In this descriptive and analytical study, all indoor swimming pools ...
Positioning of sea cages at sites with high water current velocities expose the fish to a largely unknown environmental challenge. In this study we observed the swimming behaviour of Atlantic salmon (Salmo salar L.) at a commercial farm with tidal currents altering between low, moderate and high velocities. At high current velocities the salmon switched from the traditional circular polarized g...
Backgrounds and Objectives: Swimming pools water if not disinfected properly can be one of the infection sources of different microorganisms such as staphylococcus. This study is to aware the authorities and users about the conditions existed in sheltered swimming pools in Sari and to believe the contamination of the water there, related to the existence of staphylococcus aureus. Materials an...
introduction: indoor swimming pools are the most important recreational centres. swimming pool water is responsible for the transmission of parasitic diseases. this study was performed to determine the rate of parasitic contamination and some physio- chemical parameters of indoor swimming pools in urmia during 2002. materials and methods: this study was a descriptive-cross sectional one in whic...
Introduction: Chlorination has been used as a major disinfectant process for public drinking and swimming pool water in many countries. However, it was concern over the disinfection byproducts (DBPs) by the reaction of chlorine with organic material in water and the effect on human health. The purpose of this study was to determination trihalomethane concentrations in indoor swimming pools wate...
background: trihalomethanes are toxic and dangerous substances that are formed in the presence of organic materials when water is chlorinated for disinfection. the iranian national standard, world health organization, european :union:, u.s. environmental protection agency and international agency for research in cancer standards have established a maximum contaminant level for trihalomethanes f...
background: superficial and cutaneous fungal infections can be transmitted through using covered swimming pools. this study was conducted in order to assess the dermatophyte fungi, ph and residual chlorine levels in covered pools of yazd, iran in 2009. methods: in the current descriptive cross-sectional study, carpet sampling was used to collect 100 samples from different areas of 4 randomly se...
background: contamination of swimming pools’ water can lead to the transfer of different diseases to humans. the aim of this study was to investigate the quality of water in kerman swimming pools. methods: in this cross-sectional study, sampling from swimming pools was performed before and after swimming, every week. total number of samples collected was 150 samples. samples were investigated i...
This article describes the design and theoretical foundations of the Pool Cool Diffusion Trial and reports 1st-year findings. Aims of the study are to evaluate the effects of 2 strategies for diffusion of the Pool Cool sun safety program on implementation, maintenance, and sustainability; improvements in environmental supports for sun safety in swimming pools; and sun protection habits and sunb...
