Where can forever chemicals be found?Forever chemicals can be found in a lot of consumer and industrial products, which is why it’s hard to avoid them and stop their spread.The most commonly cited example of a consumer product with a forever chemical is non-stick cookware – the non-stick coating is the guilty culprit in this scenario.However, forever chemicals can also be found in the plastic packaging of some food items, certain textile fabrics, cleaning products, cosmetics, and even toilet paper. The list goes on and on.Unfortunately, when the chemicals leak from these products, they end up everywhere, from the dust in our homes, to food and drink, and eventually our bodies. How harmful are forever chemicals to humans?Forever chemicals can have harmful effects on humans.They can increase our risk of developing health conditions such as cancer, liver disease, obesity, and fertility issues, according to the European Environment Agency.Studies have also concluded that forever chemicals can affect the immune system, and make vaccines less effective, especially in children.Low levels of forever chemicals aren’t necessarily harmful. The problem comes when we’re exposed to high levels of them. Unfortunately, since they’re in almost everything we eat, drink, and touch, the likelihood of this happening is high.Are there forever chemicals inside you?There’s a high likelihood that forever chemicals are inside you. They’ve even been found in people from remote Inuit communities, according to non-profit organisation PFAs Free.The most likely way you’ve ingested forever chemicals is through food and water, where they can be present in low levels.In the case of water, the Drinking Water Inspectorate (DWI) does have guidelines for water companies in England and Wales on what levels of forever chemicals are acceptable. But that doesn’t mean that none are allowed.The current limit is 0.1 micrograms per litre, but this rule only applies to certain, and not all, forever chemicals. Are forever chemicals bad for the environment?Forever chemicals are bad for the environment, particularly when it comes to wildlife. They can have harmful effects on the health of animals, just as they do in humans.This can lead to species decline, and reduce biodiversity over time. This is particularly concerning when it comes to endangered species, which are already vulnerable.Studies have shown that forever chemicals cause fertility issues, kidney problems, and cancer in lab animals. It’s reasonable to assume these negative health effects can also occur in wild animals.This is concerning, considering forever chemicals have polluted much of the environment.According to the NGO Wildlife and Countryside, 77% of rivers in the UK would fail the European Union’s new standards regarding safe levels of certain forever chemicals.Microplastics, which are present everywhere in the environment, have similar negative health effects on wildlife. You can read more about plastic pollution on our page Plastic Bottle Waste. Have forever chemicals been banned in the UK?Forever chemicals have not been banned in the UK.However, the government is being pressured to tighten regulations around safe levels of these chemicals in water.This comes after the US introduced new, reduced limits for the amount of forever chemicals that can be present in drinking water. They must now not exceed 4 nanograms per litre, although these limits only apply to two substances that fall under the forever chemical umbrella.The current limits advised by the DWI in the UK are 25 times higher than those proposed by the US, at 0.1 micrograms per litre for those same substances.The US has historically been behind Europe when it comes to protecting its citizens from harmful substances (and is often accused of prioritising profit over health), so this should be a good motivator for the UK to tighten restrictions in this particular area. How to avoid forever chemicalsIt’s impossible to completely avoid forever chemicals, but you can reduce your exposure to them by adopting certain habits.We’ll go over a few tips for limiting your exposure to forever chemicals in the following sections.Get a water filterForever chemicals are present in tap water, so by getting a filter installed in your tap or a filter jug, you can help reduce your exposure.

Reducing your intake of these foods will not only limit your exposure to forever chemicals, it can also help keep your diet healthy.Try not to cook with non-stick pansThe coating on non-stick pans contain forever chemicals, which can leak into food as you cook it. Try to use cast iron or stainless steel pans instead. If that’s not possible, try to cook your food on low heat to reduce the chance of forever chemicals leaking into it.Avoid buying furniture or carpets labelled “stain-resistant”While it might be practical, a lot of the coating and materials used to make furniture and carpets stain-resistant contain forever chemicals.

Regular vacuuming will help remove these chemicals from your home environment. You also have a clean home as an added bonus.Try not to buy items with forever chemicals in themLook at product labels before you buy them.

There are some companies that offer filters designed specifically to filter out more than 90% of forever chemicals, such as Zero Water. What are examples of forever chemicals? The most well-known type of forever chemicals are PFAs, which are present in the coating of non-stick, grease or stain resistant products. Teflon non-stick pans, for example, are a popular product that contain PFAs. Does bottled water contain PFAs? Some but not all bottled water contains PFAs. A 2021 study conducted by Johns Hopkins University found that 39 out of 101 different bottled water products had PFAs. The study showed products labelled as “purified” were less likely to have PFAs.
