The dangers of plastic bottles - according to research from Tros Radar

Research shows that plastic drinking bottles can leak harmful chemicals and nanoplastics, especially after cleaning in the dishwasher.

Plastic reusable bottles are a step in the right direction to reduce the use of disposable plastic. Many people now have a reusable bottle for everyday use, helping the environment by using fewer disposable bottles. But recent research shows that plastic bottles may pose health risks, especially when used frequently or cleaned in the dishwasher. The Radar research shows that both endocrine disruptors (such as DiBP) and nanoplastics are released from plastic bottles, with potential risks to your health.

The problem with plastic drinking bottles

Plastic bottles seem safe, but research shows that many models leak harmful substances, especially when heated or used repeatedly. Many reusable plastic bottles contain chemicals that can be harmful to your health. When these bottles are exposed to heat, such as in the dishwasher, these chemicals can be released and end up in your water. Research by the Antidote Foundation has shown that endocrine disruptors are found in plastic bottles cleaned in the dishwasher.

Research on harmful substances in plastic bottles

A study by the Anti-Poison Foundation tested 39 reusable plastic bottles from different European countries. These bottles were washed in the dishwasher twice a day for 10 days. The water kept in the bottles after each wash was tested for chemicals. The results were alarming: DiBP was found in more than half of the bottles. DiBP is known to interfere with hormones. Animal tests have shown that this substance can lead to malformations in the sexual organs and problems with fertility. Similar effects have been observed in humans. This makes the use of plastic bottles, especially in combination with high temperatures such as in the dishwasher, a health risk. In addition to DiBP, nanoplastics and microplastics were also found in the water, especially when the bottles had been cleaned several times in the dishwasher. This makes plastic bottles especially vulnerable to heat and abrasion.

Health risks of plastic drinking bottles

In addition to chemicals such as DiBP, plastic bottles can also leak tiny particles, nanoplastics, into your drink. A UCLA study found that a gallon of bottled water can contain as many as 240,000 nanoplastics. Although little is yet known about the exact health risks of nanoplastics in humans, animal studies suggest that these particles can cause inflammation and immune system problems. This makes it even more important to exercise caution when using plastic bottles.

Why not put plastic bottles in the dishwasher

Heat in the dishwasher can cause chemicals to be released from plastic bottles. Regularly cleaning plastic bottles in the dishwasher increases the likelihood of harmful substances, such as DiBP, entering the water. The Antidote Foundation therefore recommends washing plastic bottles by hand and avoiding exposing them to extreme heat. What is even more worrisome is that in addition to DiBP, more than 300 other unknown chemicals were found in the bottles after dishwashing. These substances have not been fully studied, meaning we do not yet know their health effects. This makes plastic bottles unpredictable and potentially dangerous for everyday use, especially when they are cleaned frequently in the dishwasher. Plastic bottles and dishwasher heat are a risky combination: this releases most endocrine disruptors.

More awareness about plastic and health

More and more organizations are sounding the alarm about the risks of plastic bottles. In a recent interview in Metronieuws, the Drinking Against Plastic Foundation warns about the ease with which we continue to reuse plastic bottles when they are not meant for that at all. The problem? You don't see the damage right away. But in the meantime, microplastics and other substances can enter your body unnoticed.

Also in the Netherlands awareness is growing that healthier drinking starts with the right bottle. Not disposable, but a safe, reusable drinking bottle without BPA or other junk. It's a small step, but one with a lot of impact - both for your body and for the environment.

Frequently asked questions and answers:

Why are plastic bottles harmful?

Plastic bottles can leak chemicals such as DiBP, which have harmful effects on hormones.

What is Di-isobutyl phthalate (DiBP)?

DiBP is a plasticizer that makes plastic flexible but can also have endocrine-disrupting effects.

What are the risks of nanoplastics in plastic bottles?

Nanoplastics can cause inflammation and immune system problems, although research into this is still in its early stages.

Why is it not safe to clean plastic bottles in the dishwasher?

The heat from the dishwasher can release harmful substances such as DiBP, which then end up in your drinking water.

What are safe alternatives to plastic bottles?

Stainless steel and glass bottles are a safe alternative, free of harmful chemicals and suitable for long-term use.
