A mining geologist has called for the suspension of fracking for gas in the main shale areas of northern England because he says the rocks contain high concentrations of toxic heavy metals.
Campaigners in North Yorkshire have said they may seek an injunction against fracking by Third Energy at Kirby Misperton because of concerns about the pipeline that would transport any produced gas.
The fracking company, Cuadrilla, has dismissed fears that shale gas in the Fylde area of Lancashire would contain large amounts of hydrogen sulphide, a hazardous gas associated with the smell of rotten eggs.
