  • `Chemical fingerprints` could reveal source of mercury pollution

    Scientists have described a new method for tracking down the source of mercury pollution from burning coal. By analysing the chemistry of the pollution, it is possible to identify which region the coal was originally from. Mercury pollution in the atmosphere comes mainly from coal-fired power stations and chemical plants. Mercury is naturally present in coal and is emitted when it is burned as ...
