Drosophila is a Reliable Biomonitor of Water Pollutionbe identified. Whether in some of the organisms this response is showed earlier than in the rest of the population exposed, it could be an alert that should to be attended to avoid more organisms being affected.

Plant Biomonitors in Aquatic Environmentsffective and useful. The species has been used in many different ways to characterize plant response to single organochlorines and metals, PCB mixtures, and as a bioassay of sediment toxicity, in the lab and in the field, to evaluate designated Areas of Concern, and to focus upon individual microsites and point source impact zones.

Although the implementation of the assay requires some training, laboratory equipment demands are very basic and samples can be easily transported and stored making the assay an ideal one for field studies.

Taking these facts into consideration, and also because of the specific action of a multitude of pollutants, Hendriks and Stouten (1994) point out that more empha

Continuous biotests are based on the permanent renewal of test water in a flow-through system, which is realized in ., fish tests, mussel tests and some bacteria tests. In semicontinuous biotests the water flow is stopped during a defined contact time (±30 min.) where the biologica
