Chemical Composition of individual particles detected at Eskdalemuir, Scotland using an ATOFMS correlations between ions observed in fine and coarse particles
Abstract
An aerosol time-of-flight mass spectrometer (ATOFMS) was used to determine, in real time, the size and chemical composition of individual particles in atmospheric air at the remote site of Eskdalemuir, Dumfries and Galloway, Scotland. Sampling began at 20:00 on day 176 of 2001 (25/06/01) and continued until 09:00 on day 181 of 2001. Back trajectories, calculated using British Atmospheric Data Centre models, reveal that two distinct air masses were encountered, a polluted air mass that passed over the British mainland before reaching Eskdalemuir and a cleaner air mass that came from the Arctic and over the Atlantic. The results were analysed to determine correlations between various chemical species in both fine and coarse particles, and thus help understand the sources of the particulate matter.
