Hanson Cement is helping the Welsh health minister with an investigation into the possible health risks of living near to a cement plant.
Penyffordd Community Council wrote to the minister Edwina Hart last month claiming there had been an increase in some cancers in people living near Hanson Cement’s Padeswood plant in Flintshire.
Hanson, formerly Castle Cement, said it welcomed the study, which would show there were “no health threats”.
The company said a 2004 study has already proved there were no health issues relating to the site, with the report endorsed by the North Wales Health Authority.
Hanson, spokesman David Weeks said: “We welcome the study. We’re happy to work with anyone who wants to look at records or see how the plant operates. The doors are open.”
