Health officials investigating fears a Flintshire cement factory could be linked to cancer have asked members of the public to share their "concerns".
Health Minister Edwina Hart ordered the investigation into concerns over the Hanson Cement plant at Padeswood.
A response team has been set up by Public Health Wales, which wants any responses by 11 June.
Hanson has previously said there are no health risks at the site, but said it would welcome any study.
Ms Hart asked Public Health Wales to investigate after claims by local residents of "an increase in the cases of various cancers".
The response team includes representatives from Betsi Cadwaladr University Health Board, Environment Agency Wales, Flintshire County Council and the Health Protection Agency.
Andrew Jones, Betsi Cadwaladr University Health Board's executive director of public health, is chairing the team.
He said: "We are taking the views of the local community very seriously and would like to invite local residents to get in touch with us to share their public health concerns about the Hanson Cement works."
He said a meeting would then be held involving all interested agencies and representatives from the local community.
He added: "This meeting will provide an opportunity for us to better understand the concerns of the local community and how we can respond to them."
