Copper concentration was estimated in tap water samples obtained from 70 households in Zagreb, serviced by a public water supply system. First-draw and flushed samples of tap water were collected in the morning and total copper concentration was determined by graphite furnace atomic absorption spectrometry with Zeeman-effect background correction. We also estimated the contribution of plumbing ...

As part of a project funded by the European Commission (EC) for the development and evaluation of multiresidue methods for analysis of drinking and related waters, 15 European laboratories evaluated a method using styrene-divinylbenzene co-polymer solid-phase extraction followed by gas chromatography/mass spectrometry. The main aim of the study was to evaluate whether the method meets the requi...

Contamination of clinical specimens by Mycobacterium gordonae is a significant endemic problem in many laboratories. To investigate this problem, 84 cases at 1 hospital were retrospectively identified during 20 months. The overall rate of specimen contamination was 2. 4%, and 72 of the contaminated specimens were respiratory. A case-control comparison showed that the risk of respiratory specime...

BACKGROUND Although the effects of replacing sugar-sweetened beverages (SSBs) with water on energy intake and body weight have been reported, little is known about how these replacements affect diet quality. OBJECTIVE To simulate the effects of replacing SSBs with tap water on diet quality and total energy intake of Lower Mississippi Delta (LMD) adults. DESIGN Retrospective analysis of cros...

A cross-sectional study investigated risk factors associated with choices to drink bottled water and tap water in rural Saskatchewan. Of 7,500 anonymous postal questionnaires mailed out, 2,065 responses were analyzed using generalized linear mixed models. Those who reported a water advisory (p < 0.001) or living in the area for £10 years (p = 0.01) were more likely to choose bottled water. Thos...

The consumption of mineral water has been increasing because of the frequent and unjustified reports of the water supply contamination. However some authors have shown that bottled waters are not always better than tap water. Mineral waters are more palatable for organoleptic characteristic because, being pure at source, they do not undergo disinfection treatments and are sometimes enriched wit...

Abstract The aim of the present study was to evaluate presence microplastics in drinking water along a large distribution supply network. Tap collected situ at sampling cabinets using an in‐line procedure that provided representative sample with minimal risk external contamination and avoided transportation volumes laboratory. Microplastics &gt; 50 μm were analysed via Fourier transform infrare...
