| chemical shift | Dependence of the resonance frequency of a nucleus on the chemical binding of the atom or molecule in which it is contained. See: chemical shift artifact. (05 Mar 2000) |
|---|---|
| chemical shift artifact | In magnetic resonance imaging, a dark band caused by a biochemical difference in resonant frequency of adjacent regions rather than a true anatomic separation. (05 Mar 2000) |
| chemical solution | See: solution. (05 Mar 2000) |
| chemical sympathectomy | Destruction of the periareterial sympathetic nerves, as in Doppler's operation, by a corrosive such as phenol. (05 Mar 2000) |
| chemical synapse | <physiology> A nerve nerve or nerve muscle junction where the signal is transmitted by release from one membrane of a chemical transmitter that binds to a receptor in the second membrane. Importantly, signals only pass in one direction. (18 Nov 1997) |
| chemical synergism | Interaction of chemicals in a mixture to produce a greater toxic effect than would be expected from the sum of the toxicities of the individual chemicals. (09 Oct 1997) |
| chemical taxonomy | An approach to the classification of organisms based on the distribution of natural products. (05 Mar 2000) |
| chemical warfare | Tactical warfare using incendiary mixtures, smokes, or irritant, burning, or asphyxiating gases. (12 Dec 1998) |
| chemical warfare agents | Chemicals that are used to cause the disturbance, disease, or death of humans during war. (12 Dec 1998) |
| riot control agents, chemical | Chemical substances which are employed during a riot in order to control or disperse the rioting parties. (12 Dec 1998) |
| micro-chemical | Of or pertaining to microchemistry; as, a micro-chemical test. Source: Websters Dictionary (01 Mar 1998) |
| models, chemical | Theoretical representations that simulate the behaviour or activity of chemical processes or phenomena; includes the use of mathematical equations, computers, and other electronic equipment. (12 Dec 1998) |
| water pollutants, chemical | Chemical compounds which pollute the water of rivers, streams, lakes, the sea, reservoirs, or other bodies of water. (12 Dec 1998) |
| commodity chemical | <chemistry> Chemicals such as ethanol that have low monetary value and are thus sold primarily in bulk. (09 Oct 1997) |
| multiple chemical sensitivity | An acquired disorder characterised by recurrent symptoms, referable to multiple organ systems, occurring in response to demonstrable exposure to many chemically unrelated compounds at doses far below those established in the general population to cause harmful effects. No single widely accepted test of physiologic function can be shown to correlate with symptoms. (cullen mr. The worker with multiple chemical sensitivities: an overview. Occup med 1987;2(4):655-61) (12 Dec 1998) |
