Metals are basic elements that do not degrade any further,  so they are able   to persist in the environment. Metals may not always stay in  the same form   because they are able to react to form different compounds.  Research a metal   that was discussed in the textbook reading such as mercury,  arsenic, or   cadmium. Create a PowerPoint presentation at least seven slides in  length,   discussing the following: 

background information on the metal, 
the cornerstone xenobiotic pharmacokinetic properties and effects of the        metal, 
the bioaccumulative effects of the metal in the environment and how it        affects humans and the environment, and 
concentration of metal that is considered toxic and symptoms of toxicity        by this metal. 

 Your   PowerPoint should be a cumulation of what you have learned   throughout the   course. For instance, if the metal has particular effects on a   certain body   system or organ, be sure to give information about these   effects.  The   assignment should meet the following requirements: 

   The length should be a minimum of seven slides, not including your        title and reference slides. 
Use speaker notes to explain the key points that are provided in the        slides. 
Include least two visual aids and/or graphics. 
A minimum of two credible sources should be used for this assignment, and        the references should be properly cited in a reference list at the end of    the     PowerPoint.
