The Queen is exposed to air pollution four times the European legal limit, it has been reported.
The figures released by the Department for Environment, Food and Rural Affairs (DEFRA) under a Freedom of Information Act request by The Sunday Times, show that Grosvenor Place, the road alongside Buckingham Palace, harbours the highest levels of toxic Nitrogen Dioxide (NO2) in the whole country.
On average, there are 152 micrograms of NO2 per cubic meter of air on the road, almost four times the European legal limit of 40 micrograms.
