Asthma, Allergies, Respiratory Ailments
. . . The annual age-specific asthma death rate increased 118 percent ( from 1.7 to 3.7 per million population ) between 1980 and 1993 . . .

Every day of the dry season, dust boosted by leaf blowers potentially contributes to the huge increase in asthma, allergies, and respiratory ailments over the past thirty years or so.

This chart is based on data from the Centres For Disease Control And Prevention (CDC) in Atlanta. Plotted against the growth in age-specific asthma deaths over a thirteen-year period you can see the corresponding growth in numbers of leaf blowers in the nation.

Asthma Growth and Leaf Blowers Growth

Pollens from trees, flowers, and grasses eventually fall to the ground. Those pollens would remain on the ground and not blow around much with normal wind patterns.

The same issues apply to weed whackers as to leaf blowers: the finer PM10 pollens and dust particles that get kicked into the air stick around for hours.

The same applies to particulates lying on the ground—herbicide particles, pesticide particles, smashed up insects, pulverised organic matter, bird, mouse, rat, and squirrel droppings, and other residues of daily life. But when somebody comes along with a noise bazooka and blows all that glop thirty feet into the air at two-hundred miles per hour, the stuff floats around and is buffeted around by normal winds for periods ranging from minutes to days.

As you already read, over fifty percent of the boosted dust is smaller-size PM10 particles which not only can enter the lungs when inhaled, but will stay in the air unaffected by gravity for hours or days.

So, if your allergies are giving you particular trouble this year, try the simple test of just looking around your neighbourhood to see how many noise bazookas are operating. Look around your neighbourhood to see how many weed whackers are kicking up dust and grass pollens.

Air pollution and respiratory problems are not improved by adding more leaf blowers.

In the years since that CDC data was collected, the number of leaf blowers in the nation has grown from around eleven million to about thirty million, with a corresponding growth in boosted dust. Nation-wide, the thirty million leaf blowers boost some nine-hundred-thousand tons of dust every dry day of the year.

The clear answer to this man-made and perpetuated health hazard is to
exercise your choice and eliminate leaf blowers from California.
