What happens to Lead when it enters the environment?

  • Lead itself does not break down, but lead compounds are changed by sunlight, air, and water. 
  • When lead is released to the air, it may travel long distances before settling to the ground. 
  • Once lead falls onto soil, it usually sticks to soil particles. 
  • Movement of lead from soil into groundwater will depend on the type of lead compound and the characteristics of the soil.
