| 520 | 3 |a"A new technique for using the tubificid oligochaete Tubifex tubifex Muller as a standard sediment bioassay is described. The various factors affecting quality assurance and control have been examined such as, the number of replicates, temperature, animal size, organic content, density, duration and repeatability. The test ls simple and straightforward and can be done with readily available and inexpensive equipment, It utilizes reproduction, the most ecologically relevant and sensitive life stage, as an end point and has been shown both in the laboratory and in a field study to be repeatable and discriminatory. The technique can be recommended as part of a suite of assays in any sediment assessment"--Abstract. |
