Atmospheric particulate matter and historic buildings

Atmospheric particulate matter, along with gaseous and precipitation pollutants, were collected close to three historic buildings; Lincoln Cathedral, Bolsover Castle and Wells Cathedral, in order to estimate the amount of sulphur and nitrogen deposited onto each. Results obtained showed that the gas...

description Atmospheric particulate matter, along with gaseous and precipitation pollutants, were collected close to three historic buildings; Lincoln Cathedral, Bolsover Castle and Wells Cathedral, in order to estimate the amount of sulphur and nitrogen deposited onto each.
