Vast swathes of the British countryside are being sprayed in pesticides containing “forever chemicals” that pollute our air, soil and waterways, and pose a threat to public health.

An analysis by the environmental group Fidra, shared exclusively with i, found that pesticides containing potentially dangerous chemicals were sprayed on the equivalent of 10.7m hectares of arable farmland in 2022 – an area roughly the size of Iceland.

The pesticides contained PFAS, or per- and poly-fluorinated alkyl substances, a group of more than 10,000 industrial chemicals that studies have linked to health problems, including cancer, infertility and developmental issues.
