| Terms for subject Environment (5582 entries) |
| composició de combustible | fuel composition | |
| composició de la població | composition of population (The constituent groupings and proportions of the total inhabitants of a given nation, area, region or city, as seen from various perspectives) | |
| composició dels residus | waste composition (The component material types, by percentage or weight, emanating from any source) | |
| composició química | chemical composition (The nature and proportions of the elements comprising a chemical compound) | |
| compost | compost (A mixture of decaying organic matter used to fertilize and condition the soil) | |
| compost alicíclic | alicyclic compound (Any substance composed of two or more unlike atoms held together by chemical bonds characterized by straight-chained, branched or cyclic properties) | |
| compost alifátic | aliphatic compound (Any organic compound of hydrogen and carbon characterized by a straight chain of the carbon atoms) | |
| compost alquílic | alkyl compound (Compound containing one or more alkyl radicals) | |
| compost aromàtic | aromatic compound (Compounds characterized by the presence of at least one benzene ring) | |
| compost d'organosílicic | organosilicon compound (Any natural substance composed of two or more unlike atoms held together by chemical bonds and containing silicon, a non-metallic element often found in rocks or minerals) | |
| compost de plom | lead compound (Lead compounds are present as gasoline additives, in paint, ceramic products, roofing, caulking, electrical applications, tubes, or containers. Lead exposure may be due to air, water, food, or soil. Lead in the air is primarily due to lead-based fuels and the combustion of solid waste, coal, oils, and emissions from alkyl lead manufacturers, wind blown dust volcanoes, the burning of lead-painted surfaces, and cigarette smoke. Lead in drinking water comes from leaching from lead pipes, connectors, and solder in both the distribution system and household plumbing) | |
| compost halogenat | halogenated compound (A substance containing halogen atoms) | |
| compost heterocíclic | heterocyclic compound (Compound in which the ring structure is a combination of more than one kind of atom) | |
| compost orgànic volàtil | volatile organic compound (Organic compound readily passing off by evaporation) | |
| compost organoclorat | organochlorine compound (Organic compounds containing a C-Cl bond) | |
| compost organoestànnic | organotin compound (Chemical compounds used in anti-foulant paints to protect the hulls of boats and ships, buoys and pilings from marine organisms such as barnacles) | |
| compost organofosforat | organophosphorous compound (Pesticides that contain phosphorous; short-lived, but some can be toxic when first applied) | |
| compost organohalogenat | organohalogen compound (Organic compounds containing a C-halogen bond) | |
| compost organometàl·lic | organometallic compound (Molecules containing carbon-metal linkage; a compound containing an alkyl or aryl radical bonded to a metal) | |
| compost organonitrogenat | organonitrogen compound (Organic compounds having a C-N bond) |
