Two-stroke engine powered leaf blowers have come to be one of the most widely used tools to maintain properties in town. They are the tool of choice for removing leaves and are used byboth landscaping services and residents.
While the effectiveness of leaf blowers for removing everything unattached from surfaces is obvious, there are several side effects that get overlooked or treated with indifference. These effects are serious and impact everyone in town, even those who don’t even use leaf blowers. The data about the health risks from blower use are well established by science . The fact that 1many of these effects occur only after regular exposure and not immediately at the time of blowing, can make the link between cause and effect more difficult to understand.
However, it doesn’t make the following risks less severe:
1. Toxic exhaust: More than 30% of a leaf blower’s fuel/oil mixture gets emitted unburned as an aerosol that contains a host of toxins that can cause eye, skin and respiratory tract irritation, neurological effects, and has been linked to lymphoma, leukemia and other types of cancer. The carbon monoxide in the exhaust can cause both mild and serious effects to the operators, from headaches, dizziness, weakness, and nausea to vomiting and disorientation
.2. Particulate matter: Blowers emit particulates that can lodge deep inside the lungs, causing or exacerbating asthma and other respiratory problems and increasing the risks of myocardial infarction, stroke, arrhythmia and heart failure.
These impacts are evenmore serious in children, the elderly, and people with pre-existing conditions. Fineparticulates stay suspended in the air we breathe for as long as a week or more, largerparticulates can float in the air for hours to days, creating a risk not only for those whooperate the blowers and are inhaling high particulate concentrations, but for all of us,after the particulates enter our homes, workplaces and schools.
