Scientists are studying the potential dangers of acid draining from disused mines into water supplies.
Ground urea, mixed with nitric acid, drained and dried, is a powerful explosive.
Schwertmannite formed in these acid drain environments following exposure and oxidation of deep (~ 0.5 → 3.5 m) clayey hypersulfidic material (pH > 4) that dried, cracked and acidified to form deep sulfuric materials (pH < 4) due to river and groundwater levels falling by nearly 2 m during the latter part of the Millennium Drought (2007 to 2010).
Acid drain cleaners use a chemical reaction between hydrogen ions and the material clogging the sink.
The mere presence of tumour-associated DNA does not necessary imply subhistologic disease, but could potentially represent cell-free nucleic acids draining into regional lymphatics (Yamamoto et al, 1997).
These results are in line with the hypothesis that aberrant fatty acid synthesis drains redox equivalents, exposing cells to higher oxidative stress.
The use of tranexamic acid, suction drains and a critical evaluation of guidelines for preventing thromboembolic events all offer reducing the risk on wound leakage and the development of SSI.
Acid overload drains so much of our energy that the body doesn't have enough energy to fight off viruses and disease.
The province's fertile coastal lands, flooded in 1953, support wheat and sugar beets; the more acid, poorly drained riverine lands are mostly pasture.
The acid was drained off of the ship using a controlled discharge of the acid into the river.
A total of five plants were closed or sold and thousands of products–such main lines as domestic black-and-white TV bulbs, finished Christmas ornaments, and acid waste drain lines were eliminated.
