There's no such thing as pure PLA, like all industrial plastics it's filled with additives to improve its properties and these have endocrine disrupting / carcinogenic properties just like all the others.
Endocrine disrupting plasticizers are not used in all plastics, and they’re not used in basic PLA.
You really cant generalize “all industrial plastics” as “plastic” is way too broad a concept. Good engineering plastics like PEI/PEEK dont even need to use any additives like plasticizers, stabilizers, cross linkers etc.
