Arsenic is also found in food, water, soil, and air. [128] Arsenic is absorbed by all plants, but is more concentrated in leafy vegetables, rice, apple and grape juice, and seafood. [ 129 ] An additional route of exposure is inhalation of atmospheric gases and dusts. [ 130 ]
Marsh test. The Marsh test is a highly sensitive method in the detection of arsenic, especially useful in the field of forensic toxicology when arsenic was used as a poison. It was developed by the chemist James Marsh and first published in 1836. [1] The method continued to be used, with improvements, in forensic toxicology until the 1970s. [2]
Arsenic forms colorless, odorless, crystalline oxides As 2 O 3 ("white arsenic") and As 2 O 5 which are hygroscopic and readily soluble in water to form acidic solutions. Arsenic (V) acid is a weak acid and the salts are called arsenates, [5] the most common arsenic contamination of groundwater, and a problem that affects many people.
Arsenic poisoning is a global problem arising from naturally occurring arsenic in ground water. The evidence that arsenic may be a beneficial nutrient at trace levels below the background to which living organisms are normally exposed has been reviewed. [ 3 ]
Frequency. >200 million [3] 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]
A recent study by the Center for Environmental Health (CEH) has revealed high levels of metal arsenic in two brands of bottled water sold by Whole Foods and Walmart. Last month, the organization ...
In its standard state arsine is a colorless, denser-than-air gas that is slightly soluble in water (20% at 20 °C) [1] and in many organic solvents as well. [citation needed] Arsine itself is odorless, [5] but it oxidizes in air and this creates a slight garlic or fish-like scent when the compound is present above 0.5 ppm. [6]
Philip Ellis. November 2, 2023 at 12:21 PM. Joe Rogan once feared that somebody was trying to poison him after he got bloodwork done and low levels of arsenic were detected—but it turned out ...
