The proper arsenic MCL continues to be debated. Some have argued that the 10 ppb federal standard is still too high, while others have argued that 10 ppb is needlessly strict. 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]
"There is no place for arsenic in bottled water," said Caroline Cox, a scientist at CEH. "Bottled water companies need to take the necessary steps to remove this toxic metal from their products ...
Arsenic poisoning (or arsenicosis) is a medical condition that occurs due to elevated levels of arsenic in the body. [4] If arsenic poisoning occurs over a brief period of time, symptoms may include vomiting, abdominal pain, encephalopathy, and watery diarrhea that contains blood. [1]
As a result, the adsorption of arsenic is reduced and dissolved arsenic accumulates in groundwater. That is why the arsenic content is higher in reducing environments than in oxidizing environments. [171] The presence of sulfur is another factor that affects the transformation of arsenic in natural water. Arsenic can precipitate when metal ...
Arsenic acid is slowly formed when arsenic pentoxide is dissolved in water, and when meta- or pyroarsenic acid (H 4 As 2 O 7) is treated with cold water. Arsenic acid can also be prepared directly from elemental arsenic by moistening it and treating with ozone. 2 As + 3 H 2 O + 5 O 3 → 2 H 3 AsO 4 + 5 O 2
Adams visited the buildings to hand out water bottles the night of Sept. 2, after being informed that initial testing showed elevated levels of arsenic in the tap water. The city first alerted ...
