EPA to Reconsider Monitoring Requirements for Airborne Lead

Lead is a metal found in the earth’s crust. However, due to human activity such as mining, burning fossil fuels and manufacturing, it has become more widespread. Lead is also toxic. Lead poisoning occurs when lead builds up in the body over time. At very high levels lead can be fatal; but even in small amounts it can cause serious health problems, particularly in children under the age of 6 who can develop mental and physical impairments.
