| radioactive contamination | <radiobiology> Radioactive substance dispersed in material or places where it is undesirable. (16 Dec 1997) |
|---|---|
| contamination | The soiling or pollution by inferior material, as by the introduction of organisms into a wound or sewage into a stream. Origin: L. Contaminatio from con =together + tangere = to touch (18 Nov 1997) |
| cross contamination | <dentistry> Passing bacteria or viruses indirectly from one patient to another through the use of improper sterilisation procedures, unclean instruments, or recycling of products. (08 Jan 1998) |
| specimen contamination | <microscopy> A change in the specimen caused by the condensation upon it of residual vapours in the microscope under the influence of electron bombardment. (05 Aug 1998) |
| direct contamination | <dentistry> Direct contact with impurities or germs. (for example by a patient sneezing on the assistant.) (08 Jan 1998) |
| equipment contamination | The presence of an infectious agent on instruments, prostheses, or other inanimate articles. (12 Dec 1998) |
| food contamination | The presence in food of harmful, unpalatable, or otherwise objectionable foreign substances, e.g. Chemicals, microorganisms or diluents, before, during, or after processing or storage. (12 Dec 1998) |
| buried soil | Soil covered by an alluvial, loessal, or other deposit (including manmade). (09 Oct 1997) |
| very poorly drained soil | <ecology> A condition is which water is removed from the soil so slowly that free water remains at or on the surface during most of the growing season. (18 Nov 1997) |
| mineral soil | <ecology> Any soil consisting primarily of mineral (sand, silt and clay) material, rather than organic matter. (12 Jan 1998) |
| poorly drained soil | <ecology> A condition in which water is removed form the soil so slowly that the soil is saturated periodically during the growing season or remains wet for long periods greater than 7 days. (09 Oct 1997) |
| saturated soil | A condition in which all easily drained voids (pores) between soil particles are temporarily or permanently filled with water, significant saturation during the growing season is considered to be usually one week or more. (09 Oct 1997) |
| hydric soil | A soil that is saturated, flooded or ponded long enough during the growing season to develop anaerobic conditions in the upper part. (09 Oct 1997) |
| soil | Unconsolidated material on the earth's surface that supports or is capable of supporting plants out-of-doors. (09 Oct 1997) |
| soil horizon | A distinct layer of soil, more or less parallel with the soil surface, having similar properties such as colour, texture and permeability, the soil profile is subdivided into the following major horizons: A-horizon, characterised by an accumulation of organic material. B-horizon, characterised by relative accumulation of clay iron, organic matter or aluminum. C-horizon, the undisturbed and unaltered parent material. (Some soils have an E-horizon, characterised by leaching of organic and other material.) (09 Oct 1997) |
