Environmental Impact
Emissions from gasoline-powered grounds-keeping equipment in general are a source of air pollution. In the United States, US emission standards prescribe maximum emissions from small engines.
In addition to adverse health effects of carbon monoxide, nitrogen oxides, hydrocarbons, and particulates generated in the exhaust gas of the gasoline-powered engines, leaf blowers pose problems related to dust raised by the powerful flow of air. Dust clouds caused by leaf blowers contain potentially harmful substances such as pesticides, mold, and animal fecal matter that may cause irritation, allergies, and disease.
Noise pollution is also a concern with leaf blower, as they emit noise levels well above those required to cause hearing loss to both the operator and those nearby. Soon after the leaf blower was introduced into the U.S., its use was banned in two California cities, Carmel-by-the-Sea in 1975 and Beverly Hills in 1978, as a noise nuisance. There are currently twenty California cities that have banned leaf blowers, sometimes only within residential neighborhoods and usually targeting gasoline-powered equipment. Another 80 cities have ordinances on the books restricting either usage or noise level or both. Nationwide, three states, Arizona, Hawaii and New Jersey, have considered laws at the state level, and five other states have at least one city with a leaf blower ordinance.

Famous quotes containing the word impact:
“One can describe a landscape in many different words and sentences, but one would not normally cut up a picture of a landscape and rearrange it in different patterns in order to describe it in different ways. Because a photograph is not composed of discrete units strung out in a linear row of meaningful pieces, we do not understand it by looking at one element after another in a set sequence. The photograph is understood in one act of seeing; it is perceived in a gestalt.”
