Industrial waste and runoff can introduce heavy metals like lead, mercury, and arsenic into floodwater. These substances are dangerous even in small amounts. They can accumulate in the body over time. This can lead to serious neurological damage and other chronic health problems.
Your Exposure Risks

Inhalation of Contaminated Air
As floodwater evaporates, it can release contaminated particles into the air. If you breathe this air, you can inhale harmful substances. This is especially true when dealing with mold growth after flooding. It can also happen when disturbed contaminated materials dry out. These airborne particles pose a significant threat to your respiratory system.
Ingestion of Contaminated Food and Water
