Plastic bottles leach harmful chemicals
Plastic bottles are one of the most popular choices for reusable water bottles. However, they have been found to leach harmful chemicals, especially when exposed to heat or sunlight.
A study by Canadian scientist William Shotyk, now working in Germany, tested 132 brands of bottled water from 28 countries, packaged in containers made from polyethylene terephthalate (PET). Shotyk found that the concentration of certain chemicals, such as antimony, increased the longer the water was stored in plastic bottles. Antimony levels doubled after six months, though they remained below the drinking-water standard set by Health Canada. Nevertheless, Shotyk emphasised the need for further research into the implications for human health.
Another study by researchers from Columbia University and Rutgers University found at least 240,000 plastic particles in the average litre of bottled water. These particles were mostly nanoplastics, which are extremely small and invisible to the naked eye. While nanoplastics have historically been challenging to study, their presence in the environment, plants, animals, foods, beverages, and humans is now being detected due to technological advancements.
Plastic bottles are also known to contain PFAS, a class of chemicals harmful to human and environmental health. Additionally, plastic bottles can leach Bisphenol A (BPA), which has been linked to various adverse health effects, including hormone disruption and obesity in animal studies. While some manufacturers produce BPA-free bottles, they may use similar compounds that serve the same purpose, potentially leading to similar health concerns.
The leaching of chemicals from plastic bottles is accelerated when exposed to heat, such as when bottles are left in hot cars. While the release of dioxins, a group of toxic chemical compounds, has been disputed by experts, other harmful substances may be released. For example, polyethylene terephthalate plastic, commonly used for single-use disposable bottles, can leach antimony, a harmful metal linked to lung, heart, and stomach issues.
Given the concerns about plastic bottles leaching harmful chemicals, many consumers are opting for alternative materials like stainless steel or glass for their reusable water bottles. Stainless steel bottles are lightweight, durable, and do not leach chemicals when exposed to heat or sunlight. They are also 100% recyclable, making them a more sustainable choice. Glass bottles are another healthy alternative, though they are more fragile and less durable than stainless steel or plastic options.

Plastic bottles are hard to clean and hold bacteria
Plastic bottles are the most popular choice for reusable water bottles. However, they may not be the healthiest option, as they can be hard to clean and may hold bacteria.
Every time you take a sip from a water bottle, you deposit bacteria inside. Over the course of a day, these bacteria can multiply by the millions, leading to a bacterial build-up. This can be worsened by the presence of moisture, contamination, and warm temperatures. If you use your bottle for drinks other than water, such as energy drinks or tea, you further increase the likelihood of bacterial growth.
One study found that more than 20% of reusable water bottles sampled contained coliform bacteria or faecal matter. Another study revealed that reusable bottles can be a breeding ground for emerging strains of antibiotic-resistant bacteria, such as Klebsiella grimontii, which can cause severe diarrhoea in people who have recently taken antibiotics.
The cleaning strategy used for your bottle makes a significant difference in terms of bacterial load. It is important to clean every part of the bottle, including the outside, the lid, and the straw (if it has one). Bottles with a wide mouth are generally easier to clean and dry, and those with a built-in straw keep your hands away.
While some plastic bottles are marketed as "BPA-free", they may still contain similar compounds that serve the same function, such as BPS, which can be just as harmful. Additionally, plastic bottles can leach chemicals, and the plastic material itself can break down, increasing the concentration of microplastics in bottled water.
As a result of these concerns, many people are switching to stainless steel bottles, which are lightweight, durable, and do not leach chemicals. They are also 100% recyclable and typically last longer than plastic bottles.
