Classification of Toxic Chemicals, Effects, and Sources

Instructions

In the previous activity we identified the the potential toxic elements in the periodic table and discussed their effects on human health and the environment. In addition to elements there are many chemical compounds that are also toxic and can contaminate the environment. The sources of these chemicals may natural or anthropogenic. Use the resources provided below to create a mindmap showing the classification of chemicals and the connection to their main sources (natural, anthropogenic, or both) and the main affected organ or system (ex. respiratory, vision, etc.)
