Contractor used noisy gas-powered leaf blower for long time including 10:32am Wednesday Oct 21, negatively affecting air quality (ozone pollution, which causes breathing difficulties and contributes to greenhouse gas emissions and climate change), individual health (trigger for asthma attacks and another emergency room visit for vulnerable people, including seniors and young children), and public health. Two-stroke gas-powered engines are so exceptionally polluting that they have been banned in almost all applications except lawn equipment. Simplest benchmark: running a leafblower for 30 minutes creates more emissions than driving a F-150 pickup truck 3,800 miles. About one-third of the gasoline that goes into this sort of engine is spewed out, unburned, in an aerosol mixed with oil in the exhaust. Cities like Jakarta, Bangkok, and Manila eliminated two-stroke engines.

Concentrations of ultrafine particles (the most hazardous PM 2.5) from commercial gas blowers were up to 54 times higher than a busy highway intersection in LA.
