I just looked for a study I remembered. One has to be careful as the study is commissioned, not peer-reviewed and they clearly have an agenda with this. However there is a compelling case that PLA will break down without leaving microplastics over time. Ingestion might still not be better than PETG or ABS, but that's not really clear to me. In the long run PLA seems to be the lest bad though.
