What is bad about polyvinyl alcohol?

Polyvinyl alcohol (PVA) can pose environmental concerns due to its persistence in the environment and potential to contribute to microplastic pollution. Additionally, while it is generally considered non-toxic, excessive exposure can lead to skin or respiratory irritation in some individuals. Its production process may also involve harmful chemicals, raising concerns about occupational safety and environmental impact. Lastly, PVA's solubility in water limits its use in certain applications where durability is needed.
