Toxic emissions from a 2-stroke gas leaf blower include:
Carbon Monoxide (CO): A 2-stroke gas blower emits 26 times as much CO as the average large car
Volatile Organic Compounds (VOCs): Benzene, 1,3 butadiene, acetaldehyde, and formaldehyde. A 2-stroke gas leaf blower produces 498 times as much VOCs as a large car.
Particulate Matter (PM), specifically PM 2.5: A 2-stroke blower emits 49 times as much PM as a large car. A 2-stroke gas leaf blower emits more pollution in 30 minutes than a Ford F-150 Raptor pickup truck produces in 3,500 miles (Edmunds 2011).
