What are my children exposed to? Why I want testing for cancer-causing chemicals
Natalie Dugdale is calling for public health bodies to test people that are worried they may have been poisoned by years of exposure to toxic waste
When she moved to the countryside two years ago, Natalie Dugdale thought it would be the perfect spot to raise her family.
Close to a lagoon in north Wales, she thought she could walk her baby, toddler and dogs on public footpaths.
But when she watched Michael Sheen's BBC documentary revealing the lagoon's history as a dumping ground of cancer-causing chemicals known as PCBs, Natalie was shocked.
Now she is part of a group of people who are worried they may have been poisoned by years of exposure to toxic waste, and are campaigning for voluntary blood testing across Wales.
But Wales' public health body has said it does not recommend blood testing for PCBs, saying it would cause more concern.
Michael Sheen followed up campaigner Douglas Gowan's concerns about dumping carcinogenic waste
Public Health Wales (PHW) said the tests did not provide "a reliable means of assessing an individual's exposure to contamination or the potential health impact".
Members of a newly formed campaign group for those living alongside some of the sites concerned have told BBC Wales they had been left "frightened and upset" and said testing would help provide "peace of mind".
Natalie could not believe her local lake in Llwyneinion, just outside Wrexham, had actually once been a dumping ground for potentially dangerous chemicals and wants to see blood testing introduced.
