Toxic exhaust fumes and emissions are created by gas-powered leaf blowers. Exhaust pollution per leaf blower per hour is the equivalent of the amount of smog from 17 cars driven one hour and is localized in the area of blower usage.

The high-velocity air jets used in blowing leaves whip up dust and pollutants. The particulate matter (PM) swept into the air by blowing leaves is composed of dust, fecal matter, pesticides, fungi, chemicals, fertilizers, spores, and street dirt which consists of lead and organic and elemental carbon. About five pounds of PM per leaf blower per hour are swept into the air and take hours to settle.

Gasoline-powered leaf blower noise is a danger to the health of the blower operator and an annoyance to the non-consenting citizens in the area of usage.
