You may choose any biological, chemical or physical agent (physical agent being a source of ionizing or
nonionizing radiation) which presents an environmental hazard, directly or indirectly, to humans. You
must describe what the agent is, the nature of the risk (e.g., exposure effects), how it moves through the
environment before reaching a target host (e.g., soil, groundwater, food chain, human), and how it moves
(and possibly changes) within the body following entry. Include hazard source(s) and recommendations
for control measures.
