In-Depth Information
The wet deposition pattern of the gas phase material is shown in
Fig. 3
. This
illustrates clearly that the prevailing meteorology transports the material in a
north-westerly direction and also that a significant amount (averaged over 1 year)
is deposited far from where it was originally applied. This represents one yearly
cycle of emission, transport and deposition. Obviously the same qualitative behav-
iour occurs every year, with the material deposited in 1 year being re-emitted and
transported further during the next.
