BACKGROUND In low and middle income countries, public perceptions of drinking water safety are relevant to promotion of household water treatment and to household choices over drinking water sources. However, most studies of this topic have been cross-sectional and not considered temporal variation in drinking water safety perceptions. The objective of this study is to explore trends in perceiv...

The taxonomic diversity and antibiotic resistance phenotypes of aeromonads were examined in samples from drinking and waste water treatment plants (surface, ground and disinfected water in a drinking water treatment plant, and raw and treated waste water) and tap water. Bacteria identification and intra-species variation were determined based on the analysis of the 16S rRNA, gyrB and cpn60 gene...

The presence of cyanobacteria and their toxins (cyanotoxins) in processed drinking water may pose a health risk to humans and animals. The efficiency of conventional drinking water treatment processes (coagulation, flocculation, rapid sand filtration and disinfection) in removing cyanobacteria and cyanotoxins varies across different countries and depends on the composition of cyanobacteria and ...

Significant advances in water treatment over the last century have resulted in massive improvements in the microbiological safety of public drinking water supplies in the UK and the developed countries. Incidences of illness due to poor treatment or post-treatment contamination are rare, but when they occur tend to attract considerable media attention. A well managed water treatment works and s...

background and aims. as a result of poor quality of public water supply in many countries, people have recently turned to bottled water consumption, the fluoride content of which is not generally consistent among different brands. this study sought to measure the fluoride concentration of public water supply in comparison with commercial brands of mineral bottled water available in tehran, iran...

drinking water quality can be deteriorated by microbial and toxic chemicals during transport, storage and handling before using by the consumer. this study was conducted to evaluate the microbial and physicochemical quality of drinking water from bottled water coolers.a total of 64 water samples, over a 5-month period in 2012-2013, were collected from free standing bottled water coolers and wat...

Introduction: Chlorination is the most common and successful method for disinfection of drinking water, especially in developing countries. However, due to the probability of formation of disinfection by-products especially Trihalomethanes (THMs) that are known as hazardous and usually carcinogenic compounds, this study was conducted to assess the investigation of THMs in drinking water of Abba...

UNLABELLED Bacterial communities migrate continuously from the drinking water treatment plant through the drinking water distribution system and into our built environment. Understanding bacterial dynamics in the distribution system is critical to ensuring that safe drinking water is being supplied to customers. We present a 15-month survey of bacterial community dynamics in the drinking water ...

HHKV includes 4 herbal plants. In this study, we used an extract from HHKV for the rats and mice orally. All mice were divided into three groups, group 1: drinking HHKV at a dose of 2 g/kg body weight/day, group 2: drinking water, group 3: drinking Giloba at a dose of 2 mg/kg body weight/day. All rats divided into four groups, two controls receiving drinking water or receiving Giloba at a dose ...
