​Microplastics affect sand crabs’ mortality and reproduction

On January 17, 2020, researchers with Portland State University reported that sand crabs "... were found to have increased adult mortality and decreased reproductive success when exposed to plastic microfibers … [Sand crabs are] a dominant organism on sandy beaches from British Columbia to Baja California, Mexico … [They] eat by filtering small particles from the water [and] are considered indicator species because their health reflects the health of the ecosystem … The study https://aslopubs.onlinelibrary.wiley.com/doi/full/10.1002/lol2.10137 found that with an increasing number of microplastic fibers internalized, crab mortality increased while the number of days that a crab held live/viable eggs decreased. Exposure to microplastics also caused variability in a crab's embryonic development rates …" - #SingleUsePlastic #FoodPackaging #PlasticWaste #PlasticPackaging #MicroPlastic #NanoPlastic
