Michael Sheen says he was snubbed by first minister over toxic pollution claims
Michael Sheen took up the job of investigating Douglas Gowan's concerns about an international chemical giant dumping carcinogenic waste in Wales
Michael Sheen says an offer to meet Wales' first minister over claims people have been poisoned by decades of exposure to toxic waste dumps "was not taken up".
The Welsh actor contacted Rhun ap Iorwerth ahead of a BBC documentary which looked into claims of widespread chemical contamination in Wales.
In Parliament on Thursday, Sheen urged MPs to back a national testing programme for historic toxic dumps to make sure sites were safe, after high levels of cancer-causing chemicals - known as PCBs - were found in soil samples and in the blood of people living near sites linked to chemical giant Monsanto.
Eastman Chemical Company, which is responsible for its legacy production, was asked to comment.
The Welsh government said addressing the issue of contaminated land was "a key priority".
One MP at the UK Parliament committee hearing later suggested to the BBC that there was confusion about whether it was the Welsh or UK government that would be responsible for any testing.
There are 12 locations in Wales which were sites of concern for Douglas Gowan
Sheen told the Welsh Affairs Select Committee that he had contacted Welsh government leader ap Iorwerth before the documentary, Buried with Michael Sheen, was broadcast in August.
"I invited him and whoever he would like to bring forward to watch the documentary before it went out publicly, because I feel like this is not about trying to point blame at anyone," Sheen said.
