Read Arsenic Exposure and Toxicology: A Historical Perspective in the attachment below.
Analyze the literature and determine the relative importance of arsenic as an environmental hazard along with knowledge of how it affects human health by answer the following questions below:
1. What has been the nature of past human exposures to arsenic? Include natural sources as well as anthropogenic sources of exposure and the exposed populations.
2. What are the chemical forms of arsenic and which are the most toxic (potent)?
3. What are the current environmental sources ("sources" meaning where does the toxicant come from) for exposure to arsenic or arsenical compounds?
4. What are the possible pathways (note "pathways" means how does the toxicant get delivered to the body) for exposure?
5. What are the current uses of arsenical compounds? Would it be possible for the government to ban arsenicals? You can use additional references please cite those additional references within your discussion.
