| application of biological safety index in two japanese watersheds using a bioassay battery. | in order to integratedly evaluate the biological safety as a water quality index, an assessment method based on three toxicity tests (algae growth inhibition, daphnia immobilization and larval fish toxicity) was developed. in this study, the developed method was used to screen, evaluate and rank the biological safety of small rivers near agricultural, industrial and residential areas. twenty-seven representative water samples were collected from the kaname river watershed and the hinata river wa ... | 2008 | 18534658 |
