Subchronic exposure to pristine and aged microplastics causes no impairment of survival or growth in a marine mysid (Americamysis bahia)
Summary
Researchers exposed the marine mysid Americamysis bahia to both pristine and weathered polyethylene microplastics across a subchronic test and found no measurable impairment to survival or growth, suggesting this crustacean may be relatively tolerant to these particle types at tested concentrations.
There are increasing concerns that µicroplastics (MPs) will be ingested by marine organisms that feed on small prey, such as plankton. In this study, we examined the biological effects (survival and growth) of exposure to pristine polyethylene MP and aged MP (aMP; length ≤&thin...
