Arsenic is also found in food, water, soil, and air. [132] Arsenic is absorbed by all plants, but is more concentrated in leafy vegetables, rice, apple and grape juice, and seafood. [ 133 ] An additional route of exposure is inhalation of atmospheric gases and dusts. [ 134 ]
Any arsenic present would appear as arsenic trioxide and then could be subjected to Metzger's test. The most common test (and used even today in water test kits) was discovered by Samuel Hahnemann. It would involve combining a sample fluid with hydrogen sulfide (H 2 S) in the presence of hydrochloric acid (HCl).

A 2007 study found that over 137 million people in more than 70 countries are probably affected by arsenic poisoning of drinking water. The problem became a serious health concern after mass poisoning of water in Bangladesh. [1] Arsenic contamination of ground water is found in many countries throughout the world, including the US.

In fact, when ingested, arsenic — a natural element found in the earth's crust — can affect several organs and systems, including the nervous, respiratory, cardiovascular, immune and endocrine ...
A ditch was dug in 1877 to provide water for hydraulic mining, but the hydraulic mining was reported to be unsuccessful. [5] In 1874, gold miners at Oro City had an assay done on the heavy, black sand that had been impedeing their placer gold recovery and found that it was the lead mineral cerussite, that carried a high content of silver.
Hering worked closely with the Los Angeles Department of Water and Power to mitigate the arsenic in their watershed. [10] She has continued to study arsenic contamination of water and ways to remove arsenic from drinking water. [14] [15] She identified that it was possible to remove arsenic from water using coagulation with ferric oxide and alum.
