Toxicity tests is a methodology to evaluate toxic responses on aquatic organisms, which have been exposed to pollutants.
Some examples of tests:
- Acute toxicity tests:
They are usually used for substances in high concentrations and the observation of the effects in 24-96 hours. Example: Average lethal concentration (LC50)
- Chronic toxicity tests:
For substances at lower concentrations, in a longer observation time, which may be up to 3 months. Example: inhibition of growth after a period of time.
