How do toxic compounds affect plankton?

Toxic compounds can have a variety of effects on plankton. Depending on the type of toxic compound, plankton may be killed directly, or their growth and reproduction may be inhibited. Toxic compounds can also disrupt the food web by reducing the number of plankton available for other organisms to feed on. Additionally, toxic compounds can accumulate in plankton, making them toxic to other organisms that feed on them.
