What is bad about polyvinyl alcohol?

Toxicity

Polyvinyl alcohol (PVA) is generally considered to be non-toxic. However, some studies have shown that PVA can cause skin irritation, eye irritation, and respiratory problems. In addition, PVA can be harmful if ingested.

Environmental impact

PVA is a synthetic polymer, which means that it is made from chemicals that are not found in nature. PVA is not biodegradable, which means that it can take hundreds of years to break down in the environment. In addition, PVA can release harmful chemicals into the environment when it is disposed of improperly.

Other concerns

PVA can also be a fire hazard. PVA burns easily, and it can release toxic fumes when it burns. In addition, PVA can be a breeding ground for bacteria.

Overall, PVA is a versatile material with a wide range of applications. However, it is important to be aware of the potential hazards associated with PVA before using it.
