Considerations in Sampling of Water

open access: yesJournal of AOAC INTERNATIONAL, 2015
Abstract Sampling water is no different than sampling any other media. It starts with the development of Sample Quality Criteria, understanding of material properties, then application of the Theory of Sampling. The main difference with sampling water as opposed to solids is the material properties.

Water sampling techniques for continous monitoring of pesticides in water

open access: yesPesticidi i fitomedicina, 2017
Good ecological and chemical status of water represents the most important aim of the Water Framework Directive 2000/60/EC, which implies respect of water quality standards at the level of entire river basin (2008/105/EC and 2013/39/EC). This especially refers to the control of pesticide residues in surface waters.

A model for predicting dissolved organic carbon distribution in a reservoir water using fluorescence spectroscopy [PDF]

open access: yes, 2004
A number of water treatment works (WTW) in the north of England (UK) have experienced problems in reducing the dissolved organic carbon (DOC) present in the water to a sufficiently low level.

EXPERIMENTAL STUDY ON THE CRYSTALLIZATION FORMATION MECHANISM OF BLIND PIPE IN WUJIAYUAN TUNNEL

open access: yesStudia Universitatis Babes-Bolyai Chemia
In the construction of high-speed railway tunnels, when passing through different geological areas, the groundwater flowing through the drainage blind pipe is easy to produce crystals to block the drainage pipe.

PRESERVATION OF WATER SAMPLES BY SALTING

open access: yesAmerican Journal of Public Health, 1912
P. Remlinger, Comp. rend. de la Soc. de Biologie, vol. 70, page 64, 1911, suggests a nmethod of inhibiting the growth of bacteria in samples of water during transportation to the Laboratory by the addition of common salt. In his experiments, ten grammes of sodium chloride were added to one hundred cubic centimeters of water. The flasks so prepared were

The investigation of the water quality and bed-sediment conditions in Cutetchi Lake, Danube Delta, Romania

open access: yesScientific Annals of the Danube Delta Institute, 2018
Danube Delta includes many ecosystems functioning in a dynamic environment that could be considered, each of them, as ”natural laboratories”. In this sense, Cutetchi Lake was chosen for conducting practical investigations (August 2016) and the obtained ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Automatic in situ sensor based on K2S2O8 oxidation method for total phosphorus detection in marine water

open access: yesFrontiers in Marine Science
Phosphorus is a key indicator for water quality management due to its role in eutrophication. The variety of phosphorus-containing substances necessitates highly sensitive detection of total phosphorus, particularly through automated methods, to ensure ...
