The public will misunderstand the National Pollutant Inventory if states don't regularly publish data on emissions from sources other than major industry, the Minerals Council has warned.

Western Australia's Environment Minister Stephen Dawson has instructed the state's EPA to check whether Yara Pilbara's ammonium nitrate plant needs tighter controls on harmful emissions.
