Question

Quizplus · Accepted Answer

Bioassays are used to determine the toxicity of marine pollutants on living organisms. One commonly used method is to calculate the concentration at which 50% of the test organisms die, known as the LC50. This provides a measure of the toxicity of the pollutant and helps in determining safe levels for human and environmental exposure.
