Water stagnation for as little as six days can completely change bacterial community composition and increase cell count. [3] Stagnant water may be classified into the following basic, although overlapping, types: Water body stagnation (stagnation in swamp, lake, lagoon, river, etc.) Surface and ground water stagnation; Trapped water stagnation.
Chuanwu Xi, molecular microbiologist and microbial ecologist at University of Michigan School of Public Health, tells Yahoo Life that many factors can result in that stale, unpleasant taste of ...
Water becomes less polar and behaves more like an organic solvent such as methanol or ethanol. Solubility of organic materials and gases increases by several orders of magnitude and the water itself can act as a solvent, reagent, and catalyst in industrial and analytical applications, including extraction, chemical reactions and cleaning.
Staling is a chemical and physical process in bread that reduces its palatability.Staling is not simply a drying-out process caused by evaporation. [1] One important mechanism is the migration of moisture from the starch granules into the interstitial spaces, degelatinizing the starch; stale bread's leathery, hard texture results from the starch amylose and amylopectin molecules realigning and ...
If water molecules become suspended among the substance's molecules, adsorbing substances can become physically changed, e.g. changing in volume, boiling point, viscosity or some other physical characteristic or property of the substance. For example, a finely dispersed hygroscopic powder, such as a salt, may become clumpy over time due to ...

People can experience acute health effects from almost any contaminant if they are exposed to extraordinarily high levels (as in the case of a spill). In drinking water, microbes, such as bacteria and viruses, are the contaminants with the greatest chance of reaching levels high enough to cause acute health effects. [34]
Video creator Jasmine (@creating.jasmine on the app) posted a video claiming that the grocery chain’s bread tends to go stale “as soon as you bring it home.”
