Algal Microplate Toxicity Test

The test method described below can be employed on its own, or as part of a battery of tests approach, to estimate the phytotoxicity potential of diverse types of liquid samples. Because it is conducted in a 96-well microplate format, the technique is simple and offers other advantages which include cost-effectiveness and spacesaving features. It is theoretically applicable to any liquid. Testing can be undertaken, for example, with samples representing the following media: (1) domestic and industrial wastewaters, treated or untreated; (2) surface, groundwater or leachates; (3) sediment interstitial waters; (4) any chemical that is soluble in water; (5) any water-insoluble chemical that can be rendered soluble by means of an organic solvent or other techniques (e.g., sonication or emulsification).
