Polyhydroxybutyrate (PHB) nanoparticles modulate metals toxicity in Hydra viridissima

Science of The Total Environment
The use of bioplastics (e.g., polyhydroxybutyrate) emerged as a solution to help reduce plastic pollution caused by conventional plastics. Nevertheless, bioplastics share many characteristics with their conventional counterparts, such as degradation to nano-sized particles and the ability to sorb environmental pollutants, like metals.
