Health risks from plastic bottles

Drinking water from plastic bottles may pose long-term health risks due to the potential release of harmful particles, according to a report. Plastic bottles have been involved in several scandals in recent years due to contamination caused by their containers.

Chemicals in plastic bottles

Toxicologist Xavier Coumoul explains that plastic bottles contain constituents that make them flexible, such as phthalates, which are known endocrine disruptors, similar to PFAS. These substances can transfer to the water, especially when the bottle is opened repeatedly, which can erode the cap and release particles.

Reducing exposure to harmful substances

To limit the risk of water contamination by plastic, Coumoul advises against drinking directly from the bottle and instead pouring the water into a glass immediately. This reduces multiple contacts with the plastic. He also notes that plastic bottles exposed to sunlight can release molecules into the water.

Practical advice for daily use

For daily hydration, it is preferable to use a water bottle, but tap water is generally recommended when possible. If a plastic bottle must be used, it is advised to pour the water into an inert compartment to minimize prolonged contact with plastic.

Balancing practicality and health

Coumoul acknowledges that it is not always possible to avoid plastic bottles for practical reasons, but he reassures that occasional use without following these precautions is not serious.
