Arsenic is a chemical element with symbol As . Arsenic occurs in many minerals, usually in conjunction with sulfur and metals, and also as a pure elemental crystal. It was first documented by Albertus Magnus in 1250. Arsenic is a metalloid. It can exist in various allotropes, although only the gray form has important use in industry.
Arsenic is notoriously poisonous to multicellular life, although a few species of bacteria are able to use arsenic compounds as respiratory metabolites. Arsenic contamination of groundwater is a problem that affects millions of people across the world.
Arsenic is present in the environment as a naturally occurring substance or as a result of contamination from human activity. It is found in water, air, soil and foods. In foods, arsenic may be present as inorganic arsenic (the most toxic form of arsenic) or organic arsenic. FDA has been monitoring the levels of arsenic in foods for decades, and in 2011, increased its testing. The latest results confirmed that the amount of arsenic in apple juice is low. The agency has studied consumption levels among children and adults, and completed a scientific assessment. Based on this work, FDA is confident in the overall safety of apple juice for children and adults.

When I originally commented I clicked the "Notify me when new comments are added" checkbox and now each time a comment is added I get three e-mails with the same comment. Is there any way you can remove me from that service? Thanks a lot!sedation dentistry birmingham al
