R. Chester et al., Trace metal chemistry of particulate aerosols from the UK mainland coastalrim of the NE Irish sea, ATMOS ENVIR, 34(6), 2000, pp. 949-958
Data are provided on the long-term average trace metal composition of aeros
ols collected at two urban (Liverpool and Preston) and one rural (Lancaster
) site on the UK mainland coastal rim of the NE Irish Sea. There are variat
ions in the trace metal composition of aerosols at the urban and rural site
s, with evidence of local urban 'hot spot' sources of Ni, Zn and Cr. Data f
rom the three sites are combined to give an average trace metal composition
of the aerosol at the NE Irish Sea UK coastal sites, This aerosol has high
er average concentrations and EFcrust values for some trace metals, e.g. Ni
and Cr, than those at other Western European coastal sites but, relative t
o crustal material, there is general 'uniformity of composition' in the ext
ent to which Ni, Cr, Cu, Zn and Pb are enriched in all the coastal aerosols
. To estimate the composition of the aerosol transported to the NE Irish Se
a across the UK mainland coast, the coastal strip is partitioned into urban
and rural regions and an average trace metal composition for the 'whole ri
m' aerosol is given. This is used to make an 'upper limit' estimate of the
trace metal composition of the aerosol transported to open-sea regions of t
he NE Irish Sea, which shows a generally similar enrichment of trace metals
, relative to crustal material, as that of the North Sea aerosol. (C) 2000
