Microplastics (MPs) – Effect on Caddisfly Species Reported

According to an April 20, 2020 article published in Environmental Science and Pollution Research by researchers with the Federal Institute of Hydrology in Koblenz, Germany https://link.springer.com/article/10.1007/s11356-020-08790-5 caddisfly species “… actively used sand, PET and PVC MPs for building tube-like portable or emergency cases … case stability decreased with increasing PVC and PET particle content in the cases, suggesting that MPs may threaten caddisflies by destabilising cases. When case stability is reduced, the protective function of the cases is limited and the larvae may be more prone to predation. Additionally, larvae may be washed away by the current as plastic is lighter than sand. Both effects could limit the caddisfly’s survival, which could have far-reaching consequences as caddisfly larvae are important primary consumers in aquatic ecosystems …” #Caddisflies #MicroPlastics #SingleUsePlastic #PlasticWaste #PlasticPackaging
