Arsenic is the same chemical substance, namely As. <\/span><\/h2>\r\nOn the internet, we will find information about both *arsen* and *arsenic*, but in fact, it's about the same chemical formula.<\/span>\r\n\r\nThe presence of arsenic in nature in principal natural deposits in the Earth's crust.<\/span>\r\n\r\nArsenic enters the Earth's crust either through corrosion, or through petroleum production, semiconductor production, or due to its use as a feed additive and herbicide.<\/span>\r\n\r\nArsen is usually found in high levels in groundwater and in lower levels in surface water (i.e., lakes or rivers).<\/span>\r\n\r\nArsenic is poisonous to humans, and ingesting 1000 milligrams of arsenic means severe poisoning. The effects of arsenic poisoning when small amounts are ingested appear very slowly and include skin lesions or circulatory system problems, and the risk of cancer increases.<\/span>\r\n\r\nTesting for arsenic is recommended because arsenic-contaminated water is colorless and odorless. Water with arsenic looks the same as water without arsenic.<\/span>\r\n\r\nThe maximum limit established by Law \u201cProbable Water Quality\u201d 311\/2004 is 10 \u03bcg\/l in water.<\/span>\r\n

Arsenic filters<\/span><\/h2>\r\nArsenic is difficult to remove from water. However, with the right filters, the results can be impressive. There are primarily three types of arsenic filtration systems:<\/span>\r\n
