lenduv orgaaniline ühend

Usage examples

Lenduvad orgaanilised ühendid (LOÜ) on sünteetilised ja looduslikud ained, mis lenduvad isegi toatemperatuuril. Levinuimad LOÜd on metaan, aldehüüdid, ketoonid jt. Selliseid aineid esineb kodukeemiatoodetes. Suures koguses esineb neid aga lahustites ja lakkide, värvide, liimide koostises.

LOÜ abbreviation

volatile organic compound

Usage examples

Most air toxics are organic chemicals, comprising molecules that contain carbon, hydrogen, and other atoms. Many are volatile organic compounds (VOCs), organic compounds that readily evaporate. VOCs include pure hydrocarbons, partially oxidized hydrocarbons, and organic compounds containing chlorine, sulfur, or nitrogen. They are widely used as fuels (e.g., propane and gasoline), as paint thinners and solvents, and in the production of plastics. In addition to contributing to air toxicity and urban smog, some VOC emissions act as greenhouse gases and, in so doing, contribute to global warming.
