I don’t think so because in the health risk case it must be very tiny bits falling off that gets you. People aren’t swallowing pieces of water bottle, it poisons you slowly over time (carcinogens). It could be that the shell has tiny bits that fall off easily when exposed to water but the inside is durable, but AFAIK it is a homogenous material.
