| 520 | 3 |a"Studies were carried out to evaluate the battery of tests approach and the use of simple solvent extraction procedures on waters and suspended particulates within a relatively unpolluted agricultural area. Many of the bioassays used, which were very responsive in other more polluted areas, were non responsive with the samples collected from the Nith River. The bioassay tests which were responsive were the ATP-TOX System, SOS-Chromotest with and without S9 activation and the Nematode test (Panagrellus redivivus). Solvent extraction procedures using 100% DMSO, 100% methanol and 10% DMSO with 10% methanol were also shown to be equally effective in extracting toxicants/genotoxicants from suspended particulates. They also produced greater responses in the bioassays compared to pore water and Milli-Q water extracts"--Abstract. |
