Strontium-90 pollution can be bioremediated with the green microalga .

Strontium-90 (Sr) is an artificial radioisotope produced by nuclear fission, with a relatively long half-life of 29 years. This radionuclide is released into the environment in the event of a nuclear incident, posing a serious risk to human and ecosystem health. There is a need to develop new efficient methods for the remediation of Sr, as current techniques for its removal have significant technical limitations and involve high energy and economic costs.
