Microplastics – Beneficial Effects of Biofilm Ingestion Reported

The abstract of a December 3, 2021 Environmental Pollution study https://doi.org/10.1016/j.envpol.2021.118622 by researchers with Netherlands Wageningen University, Spain Universidad de Alcalá, and Spain Universidad Autónoma de Madrid reports that “… Ingestion of microplastics by aquatic organisms is often harmful due to the dilution of their regular food with low-calorie microplastic particles, but can also be beneficial if nutritious biofilms are present on the microplastic surface … we quantified these harmful and beneficial effects on Daphnia magna … and determined the trade-off between these counteracting effects ... Our results show that the organisms grew better when exposed to biofouled microplastic compared to pristine microplastic … These results contradict previous studies were only pristine microplastic were used and demonstrate that the ruling paradigm of unambiguously adverse microplastic effects is not ecologically justifiable …” #MicroPlastics #PlasticWaste #SingleUsePlastic @WURmarine
