Background and purpose: Awareness of people about drinking water impurities and the demand for better water quality have led to widespread application of point-of-use (POU) water treatment devices. The aim of this study was to investigate the bacteriological quality of water produced by household water treatment devices. Materials and methods: This cross-sectional descriptive study was perfo...

BACKGROUND An approach to the study of the pharmacokinetics of drugs in the lung is to measure their concentrations in bronchial biopsy specimens. The main criticism of this technique is that bronchial biopsy specimens consist of more than one tissue type and that drugs are often not distributed evenly. The morphology of bronchial biopsy specimens and the distribution of water between the extra...

In this work, a fast, simple and economic method is proposed for the determination of imazalil in water samples by flow injection photoinduced chemiluminescence. In this method, imazalil degrades in basic media through the use of a photoreactor, and the resulting photofragments react with ferricyanide and generate the direct chemiluminescence signal. To the authors' knowledge, this is the first...
