Lead in Aviation Gas

What is aviation gas?

Aviation gas (also known as 'avgas') is a fuel commonly used by small piston-engine (propeller or rotary) aircraft and is the most widely used transportation fuel containing lead in the U.S. Lead from aviation gas emissions is an air pollutant that threatens the health of children. When lead air pollutants settle, they contaminate the neighborhoods around airports and can create soil and dust with levels of lead that are unsafe for children.

Why is this a concern?

There is no known safe level of lead childhood lead exposure. Lead is a toxic metal and can be especially harmful to children as their bodies are still rapidly growing. Lead poisoning can lead to lifelong learning, behavioral, reproductive, heart, and other health problems.

How can I keep my family safe?
