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.

Individual states can establish lower arsenic limits; New Jersey has done so, setting a maximum of 0.005 mg/L (5 ppb) for arsenic in drinking water. [29] A study of private water wells in the Appalachian mountains found that six percent of the wells had arsenic above the U.S. MCL of 0.010 mg/L. [30]
It is also potentially in drinking water, e.g. from plumbing and fixtures that are either made of lead or have lead solder. [127] [136] Since acidic water breaks down lead in plumbing more readily, chemicals can be added to municipal water to increase the pH and thus reduce the corrosivity of the public water supply. [127]
including food ingredients such as citric acid, sodium benzoate, and high fructose corn syrup. High fructose corn syrup is used in food products to enhance shelf life. A pilot study was conducted to determine if high fructose corn syrup contains mercury, a toxic metal historically used as an anti-microbial. High fructose corn syrup samples were
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.
Well, there are no health benefits attached to drinking regular or diet soda, and they actually increase your risk of certain health problems, so it’s best to keep them on the once-in-a-while ...
The acidic and metal-rich AMD is a major source of environmental pollution, contaminating nearby surface waters and groundwater, harming ecosystems and rendering water unsuitable for drinking. [24] AMD can persist for extended periods, even long after mining activities have ceased, leading to continual environmental degradation.
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 ...
