Azathoth is a deity in the Cthulhu Mythos and Dream Cycle stories of writer H. P. Lovecraft and other authors. He is the supreme deity of the Cthulhu Mythos and the ruler of the Outer Gods, [1] and may also be seen as a symbol for primordial chaos, [2] therefore being the most powerful entity in the entirety of the Cthulhu Mythos.
The data logger (white cabinet) records temperature, specific conductance, and dissolved oxygen levels. The complexity of water quality as a subject is reflected in the many types of measurements of water quality indicators. Some measurements of water quality are most accurately made on-site, because water exists in equilibrium with its ...
Arsenic contamination of groundwater is a form of groundwater pollution which is often due to naturally occurring high concentrations of arsenic in deeper levels of groundwater. It is a high-profile problem due to the use of deep tube wells for water supply in the Ganges Delta, causing serious arsenic poisoning to large numbers of people. A ...
Freshwater environmental quality parameters are those chemical, physical and biological parameters that can be used to characterise a freshwater body. Because almost all water bodies are dynamic in their composition, the relevant quality parameters are typically expressed as a range of expected concentrations.
A 2007 toxicity report for the National Toxicology Program provided evidence that high doses of chromium 6 caused cancers of the gastrointestinal tract in rats and mice at levels higher than 5 mg/L of water, (5 ppm, or 5,000 ppb). [41] [42] Average hexavalent chromium levels in Hinkley were recorded at 1.19 ppb, with an estimated peak of 20 ppb.
The researchers said that of all the cosmic bodies they have studied that struck Earth in the last 500 million years, only the one that exterminated the dinosaurs was a water-rich asteroid.
Water quality laws govern the protection of water resources for human health and the environment. Water quality laws are legal standards or requirements governing water quality, that is, the concentrations of water pollutants in some regulated volume of water. Such standards are generally expressed as levels of a specific water pollutants ...
