While PVC kiddie pools may be a fun and affordable option for cooling off during the summer, there are some safety concerns to consider. PVC, or polyvinyl chloride, is a type of plastic that can contain harmful chemicals, including lead. If these chemicals leach into the water in your pool, they can be potentially harmful to your child's health. There have been reports of children becoming ill after playing in PVC kiddie pools, so it's important to take precautions. If you do decide to purchase a PVC pool, look for one that is labeled "lead-free." You should also avoid letting your child play in the pool for extended periods of time and make sure to empty and clean the pool regularly.
