Unraveling individual and combined toxicity of microplastics and tetracycline at environment-related concentrations to coral holobionts.

Coral holobionts constitute the foundational organisms of coral reef ecosystems. As an emerging pollutant, the projected accumulated levels of microplastics (MPs) are expected to continue increasing. Meanwhile, due to their properties, MPs can absorb multiple other marine pollutants, such as antibiotics (ATs).
