Despite evidence that ‘forever chemicals’ are already present in the majority of people’s blood, there is relatively little UK research looking into the associated health problems – a situation often used by the government and chemicals industry to delay action.(4) However, peer-reviewed studies conducted in other countries have connected PFAS exposure to a range of serious health problems including an increased risk of cancer and decreases in both fertility and the immune system’s ability to fight infections.(5) There is particular concern over childhood exposure since PFAS has also been linked to behavioural changes as well as developmental effects or delays in children, including low birth weight and accelerated puberty.(6)
Expert Committee on Pesticide Residues in Food (PRiF) which tests roughly 2,500 one-kilogram samples of food each year.(7) Food items are taken from the shelves of supermarkets and other food outlets across Great Britain, meaning that all food tested was originally destined to be purchased and eaten by ordinary consumers.
PAN UK’s findings mirror recent research revealing that residues of 31 different PFAS pesticides were detected in European fruit and vegetables between 2011 and 2021. Like the UK, strawberries were found to be the most likely EU-grown produce to contain ‘forever chemicals’ with a high of 37% in 2021.(8) However, this figure is dwarfed by its UK equivalent which shows that, of the 55 samples of UK-grown strawberries tested in 2022, 91% (50) contained residues of PFAS pesticides.
There are 25 PFAS pesticides currently in use in the UK, six of which are classified as ‘Highly Hazardous’.(9) The list includes the insecticide lambda-cyhalothrin which, in addition to being a ‘forever chemical’, is highly toxic to both humans and bees.(10) In 2022, 9,200 kg of lambda-cyhalothrin was applied to 1.69 million hectares of UK land, the equivalent of eleven times the size of Greater London.(11) Farmers are generally unaware that they are spraying ‘forever chemicals’ on their crops because there is no information on the label.
The Environment Agency does not actively sample rivers for any of the 25 PFAS pesticides currently in use in the UK, so the extent to which these chemicals are running off agricultural fields to contaminate rivers and other water sources remains unknown.(12)
Mole added, “Pesticides are the only chemicals that are designed to be toxic and then released intentionally into the environment. Despite this, the UK government’s much-delayed plans for limiting the negative impacts of PFAS focus solely on industrial chemicals, ignoring pesticides entirely.(13) PFAS pesticides are absolutely unnecessary for growing food and are an easily avoidable source of PFAS pollution. Getting rid of them would be a massive win for consumers, farmers and the environment.”
Dr Shubhi Sharma from CHEM Trust said: “PFAS are a group of entirely human-made chemicals that didn’t exist on the planet a century ago and have now contaminated every single corner. No one gave their consent to be exposed to these harmful chemicals, we haven’t had the choice to opt out, and now we have to live with this toxic legacy for decades to come. The very least we can do is to stop adding to this toxic burden by banning the use of PFAS as a group”.
PAN UK is urging the UK government to urgently ban the 25 PFAS pesticides currently in use and increase support for farmers to help them end their reliance on chemicals and adopt safer and more sustainable alternatives. The organisation is also echoing health and environment NGOs that are calling for the UK to work towards achieving a PFAS-free economy by 2035.(14)
