Chlorination is the most popular method for disinfecting swimming pool water; however, although pathogens are being killed, many toxic compounds, called disinfection by-products (DBPs), are formed. Numerous epidemiological publications have associated the chlorination of pools with dysfunctions of the respiratory system and with some other diseases. However, the findings concerning these associ...
Objectives: Chloramines are by-products of chlorine disinfected swimming pools and are hazardous to people if chloramines evaporate into the air. There is evidence that chloramines cause upper respiratory tract and eye irritation. It was suspected that ozone treatment in addition to chlorine disinfection will reduce chloramine levels in the pool. The following study compared chloramine concentr...
This article is focused on the epidemiological evidence on the health impacts related to disinfection by-products (DBPs) in swimming pools, which is a chemical hazard generated as an undesired consequence to reduce the microbial pathogens. Specific DBPs are carcinogenic, fetotoxic and/or irritant to the airways according to experimental studies. Epidemiological evidence shows that swimming ...
The presence of Cryptosporidium oocysts in swimming pools in Barcelona was studied. The possible influence of the different parameters related to water conditions, pool structure and users has also been analyzed. Cryptosporidium oocysts were detected in 54% of the swimming pools analyzed and in 85% of the sport centers checked. Oocysts concentrations ranged from 0 to 30 oocysts/L. Among paramet...
Introduction; Swimming pools are one of the important recreational places that due to direct relationship to different groups of people, can be a good carrier for bacterial, fungal and parasite diseases. This study was conducted to evaluate hygiene condition of the pools. Material and methods: In this descriptive study, all of active swimming pools of Bandar Abbas (based on Salvato recommendat...
Background and Aim: Rapid and precise typing of E.coli is a prerequisite for epidemiological surveillance and controlling of infection caused by this bacterium. The present study was conducted to determine the molecular diversity of E.coli strains isolated from human and swimming pools samples using Enterobacterial Repetitive Intergenic Consensus (ERIC) method. Materials and Methods: This was ...
