Atmospheric deposition of trace metals to urban and coastal environments
type: CreativeWork
description: The atmospheric flux (wet and dry) of trace metals (Ni, Co. Cu, Pb, Cd, Al and Na) to the Irish Sea and the North-West of England is presented. The fluxes were calculated from determined trace metal concentrations of aerosols (Al, Fe, Mn, Cd, Co, Cr, Cu, Na, Ni, Pb, V and Zn) and rainwaters (Ni, Co, Cu, Pb, Cd, Al and Na), which were collected using specially designed sampling equipment. The particulate material was analysed using inductively coupled plasma - mass spectroscopy (ICPMS) and also atomic absorption spectroscopy techniques after a complete aciddigestion (HFIHNO3). The dissolved rainwater metal concentrations were determined using the electroanalytical technique adsorptive cathodic stripping voltammetry (ACSV). This technique also enabled dissolved metal Organic complexation to be determined in the rainwater. The results indicated that the trace metal aerosol and rainwater concentrations detected for the Irish Sea and urban areas vary considerably during an annual period. This can be attributed to (i) air mass source and (ii) rainwater washout. Geometric mean aerosol concentrations (ng m 3) were calculated for the Irish Sea aerosol (Al, 210; Fe, 159; Mn, 6.2; Cd, 0.26; Co, 0.17; Cr, 2.0; Cu, 5.3; Na 1140; Ni, 4.2; Pb, 19; V, 4.1; Zn, 32) and North-West England aerosol (Al, 365; Fe, 589; Mn, 21; Cd, 0.80; Co, 0.68; Cr, 13; Cu, 17; Na 2208; Ni, 16; Pb, 45; V, 7.7; Zn, 153) along with total (dissolved + particulate) volume weighted mean concentrations (j.ig l') for the Irish Sea rainwater (Al, 32; Cd, 0.05; Co, 0.05; Cu, 1.8; Na 1998; Ni, 1.1; Pb, 0.73) and North-West England rainwater (Al, 72; Cd, 0.14; Co, 0.15; Cu, 2.9; Na 1274; Ni, 1.7; Pb, 1.82). Air mass analysis studies illustrated the affect on the aerosol trace metal concentrations. For Fe, Mn, Cd, Cu. Pb, V and Zn the Irish Sea aerosol concentrations decreased in the order E> S > N > W. Calculated total inputs to the Irish Sea for Cu (131 t yr:'), Pb (82 t yr') and Cd (3.2 t yr.') were of similar m…
