Leaf blower – wikipedia gas x while pregnant

Emissions from gasoline-powered grounds-keeping equipment in general are electricity dance moms song a source of air pollution [4] and more immediately (when powered by internal combustion engines, rather than by electricity), noise pollution. In the United States, US emission standards prescribe maximum emissions from small engines. The two-stroke engines used in most leaf blowers operate by mixing gasoline with oil, and a third of this mixture is not burned, but is emitted as an aerosol exhaust. These pollutants have been linked to cancer, heart disease, and asthma. [5] A 2011 study found that the pollutants emitted by a leaf blower operated for 30 minutes is comparable to the amount emitted by a Ford F-150 pickup truck driving from Texas to Alaska. [6]

In addition to the 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 wd gaster cosplay tutorial clouds caused by leaf blowers contain potentially harmful substances such as pesticides, mold, and animal fecal matter that may cause irritation, allergies, and disease.

Leaf blowers also present an occupational hearing hazard to the nearly 1 million people who work in lawn service and ground-keeping. [7] A recent study assessed the occupational noise exposure among groundskeepers at several North Carolina public universities and found noise levels from leaf blowers averaging 89 decibels (A-weighted) and maximum sound pressure levels reaching 106 dB(A), both far exceeding the National Institute for Occupational Safety and Health ( NIOSH) Recommended Exposure Limit of 85 dB(A) [8] Bans [ edit ]

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 gas outage 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. [9] See also [ edit ]
