Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir.

In a monohaloacetic acid, a single halogen replaces a hydrogen atom: for example, in bromoacetic acid. Further substitution of hydrogen atoms with halogens can occur, as in dichloroacetic acid and trichloroacetic acid. Haloacetic acids are a common contaminant in treated drinking water, particularly water subjected to chlorination.
Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH).Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average.
Sulfur water is made out of dissolved minerals that contain sulfate. These include baryte (BaSO 4), epsomite (MgSO 4 7H 2 O) and gypsum (CaSO 4 2H 2 0). [1] It is reported that a notable change in taste to the water is found dependent upon the type of sulfate affecting the water.
Over nearly 25 years, women who had the greatest adherence to the Mediterranean diet had a 23% lower risk of death than women who followed it the least, a new study finds. The more women followed ...
Ultrapure water (UPW), high-purity water or highly purified water (HPW) is water that has been purified to uncommonly stringent specifications. Ultrapure water is a term commonly used in manufacturing to emphasize the fact that the water is treated to the highest levels of purity for all contaminant types, including organic and inorganic compounds, dissolved and particulate matter, and ...
A study published in Circulation looked at the diet data of 166,270 women and 43,970 men who did not have cardiovascular disease when they enrolled in the mid-1980s and early 1990s. They answered ...
