Prevalence of CO2 from disused mineral mines and the implications for residential buildings: research
In 2017 the NHS Lothian Incident Management Team investigated reported cases of ill health affecting residents of a recently built local authority housing estate. This research is looking for similar incidents and considers implications for building standards.
