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.

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
