For many, summer is the perfect season to spend time outdoors, providing ample opportunities to explore nature with loved ones. Whether you’re hiking, biking, or enjoying a picnic, there are steps you can take to reduce your risk of exposure to harmful chemicals.

When it comes to clothing, rain jackets could be a source of exposure. A recent study by the Danish Consumer Council THINK Chemicals found that 13 out of 17 rain jackets from Amazon, Shein and Temu contained PFAS. 12 of them contained PFAS that are illegal in the EU (read our news story on this study here).

Per- and polyfluoroalkyl substances (PFAS) are a family of over 10,000 highly persistent chemicals. They hardly degrade in the natural environment, leading to them lasting for generations, which is why they are sometimes called the ‘forever chemicals’. Exposure to some PFAS has been linked to adverse health problems, such as certain cancers, reduced fertility, and immune system disruption.

PFAS have been used in outdoor gear due to their water-repellent properties. When buying rain jackets and other outdoor wear, and any wash-in or spray-on waterproofing for shoes and clothes, look out for products labelled PFAS-free or PFC-free.

Now, for getting your bike ready. In 2023, the Danish Consumer Council THINK Chemicals found that several commercially sold bike oils contained forever chemicals, covered by CHEM Trust here. 44% of the bike oils tested were found to contain PFAS. When buying bike oils, avoid those labelled as containing PTFE or Teflon, which is a type of PFAS.

Picnics are another favourite summertime activity, and there are some key changes you can make to avoid harmful chemicals.

Go for organic fruit and vegetables where you can, to avoid the pesticides used on non-organic produce. Some of these pesticides may contain harmful chemicals such as PFAS. While washing and peeling can help remove some of the residues, some pesticides are absorbed deep into the plant, so choosing organic where possible is the best choice for reducing your risk.

When it comes to packaging up your picnic foods, choose glass jars and stainless-steel containers. Plastic packaging may contain harmful chemicals, such as bisphenols and phthalates, that can leach onto your food and drink. In addition, avoid black plastic cutlery and utensils, which are sometimes made from recycled electronic waste, meaning they can contain hazardous chemicals such as toxic flame retardants.

CHEM Trust supports the EU-wide universal PFAS restriction, which will apply to all PFAS, and once introduced, will control pollution at source.
