Limited effects of chronic exposure to environmentally relevant concentrations of microplastics across biological levels in mussels (Mytilus galloprovincialis)

Summary

Good news for seafood lovers: a new study found that mussels exposed to realistic, everyday levels of microplastics in the ocean showed only minor effects on their health and growth, not the dramatic harm seen in some earlier lab studies that used unrealistically high plastic doses. This suggests that when it comes to mussels raised for food, real-world microplastic pollution may be less immediately damaging than previously feared, though it doesn't mean microplastics are harmless, just that this study didn't find major red flags at typical ocean concentrations.
