Toxic Legacy: Fears of PCB Poisoning in Wales

Concerns are rising among residents in north-east Wales regarding potential exposure to cancer-causing chemicals known as PCBs. These chemicals were historically dumped by US firm Monsanto, with sites identified near Wrexham and other locations. Residents, like Natalie Dugdale, worry about the health of their families and children who may have been exposed to these "forever chemicals."

Campaigners, including those living near former Monsanto works, are urging for voluntary blood testing, alongside a national soil testing program. They believe testing would offer crucial peace of mind and clearer answers about potential exposure. However, Public Health Wales has stated that blood testing is not recommended, citing its unreliability in assessing individual exposure and the potential for causing unwarranted concern due to the lack of treatment for PCBs.
