This letter, written by Newton resident Al Leisinger, was presented to the City Council at the recent meeting of the Council’s Committee on Program and Services. It expresses widespread sentiment that the city ordinance governing the use of leafblowers has in practice fallen far short of expectations for the following reasons: the police department has enforced it inadequately and responded haphazardly to citizens’ complaints; many landscapers have ignored the ordinance altogether; and even when enforced, the ordinance does little to lessen the health risks inherent to leafblowers, both gas and battery-powered.

Subject: Leafblowers

I write to you today to strongly support action in support of Councillor Lisle Baker’s proposals on leafblowers. For me, there are three main issues: (1) compliance with the current leafblower ordinance, (2) dangers of leafblowers, and (3) strengthening this ordinance.

(1) Compliance: In my walks with a mask around Newton this Spring, Summer, and Fall, I have been impressed with the amount of out-of-compliance use of leafblowers. Use of too-powerful gas blowers; use of multiple leafblowers at the same time on the same residential property; blowers used to blow garden debris into streets; failure to stop blowing when someone walks by on the sidewalk; and, occasionally, failure of the Newton Police to respond effectively to calls about these matters.

I have abandoned calling the police, because of the failure of the police to effectively respond.

(2) Dangers of leafblowers: I’m not citing too many technical articles here, just listing the dangers.

2.1: Leafblower noise interrupting people working from home. (note: today I just spent 2 hours trying to work at my home with extremely loud multiple leafblowers running across the street.)  Some people are medically affected strongly by leafblower noise.

2.2: Gas leafblower gas combustion emissions.

Scientific studies show that running one gas leafblower emits much more combustion emissions than running a gas automobile.  I note that (e.g.) UK has just passed a law banning gas- and diesel–powered autos after 2030 (see BBC, 11/18/2020, “’New cars and vans powered wholly by petrol and diesel will not be sold in the UK from 2030,’ Prime Minister Boris Johnson has said.”) out of environmental concerns. But despite this, gas leafblowers are used widely in the USA, creating a large amount of global-warming gasses.  These gasses can also be toxic to persons who breathe them.

2.3: (THE WORST DANGER) Small-particulate matter, disease, early death, and COVID-19:

The small particles known as “PM2.5” are an invisible and very nasty form of pollutant. Particles of under PM2.5 remain in the air for up to several hours after discharge. They are breathable, and pass the lung-blood barrier going directly into the blood of the circulatory system. PM2.5 particles are those with an aerodynamic equivalent diameter less than or equal to 2.5 μm in ambient air.

It has been estimated that PM2.5 pollution in China leads at least 1 million people per year to die early. Studies on other countries give similar statistics. Fine particulates in air are associated with increased risks of lung cancer, COPD, ischemic heart disease, allergic reactions. Further, higher atmospheric PM2.5 can create lung inflammation, and is strongly associated with increased risk of susceptibility and severity of COVID-19 patient symptoms.

2.4: Even electric leafblowers create PM2.5: Though electric leafblowers do not emit combustion products, they do kick up PM2.5 debris. So they are a bit safer, but not safe.

2.5: Composition of PM2.5 particles thrown up by leafblowers: Although not everything is known about the composition of leafblower emitted PM2.5, here are some known constituents of the particle: fecal material, fertilizers, fungal spores, pesticides, herbicides, pollen, and other biological substances  including pollens and pollen fragments, animal dander, and molds. Other possible constituents are small amounts of toxic metals arsenic, chromium, lead, and mercury, found in road dust.

2.6: Risk to the health of lawncare workers: Lawncare workers themselves are the people most likely exposed to gas and particulate Leafblower detritus. And although owners of leafblower-using lawncare companies have sometimes testified in favor of using leafblowers, significantly the actual workers using the leafblowers are exposed to the dangers. Many of these worker employees are people of color, immigrants, and also face increased risk of getting COVID-19, so that their exposure to particulate and gas leafblower releases complicates their healthcare situation.

I think we should be extremely sensitive to their health risks.

  1. Strengthening the leafblower ordinance: I believe that, in view of the health risks mentioned in section (2) above, we should move for a total ban on the use of leafblowers. But even if we can’t enact a total ban, the current ordinance is weak because it doesn’t stop the release of particulates by electric blowers, and it allows too much use of leafblowers.

Sincerely,

Al Leisinger
