Mass Fluxes of Main Components and Trace Metals

2 Mass Fluxes of Main Components and Trace Metals [Pg.383]

The total mass fluxes (Fig. 13.7) ranged between 1 and200mgm2d, in agreement with the investigations of Wasmund et al. (2000) during 1998 at the same station. Significant [Pg.383]

According to the global crustal ratio of Taylor (1964), enrichment factors (EF) for Cd, Cu, Zn, Pb, As, Ni, Mn, and Fe were calculated for the trap material and SPM by the equation [Pg.384]

FIGURE 13.7 Seasonality of the composition, trace metal contents (nmol/g, pmol/g) in the trap material, Corg (mg/m d), and trace metal mass fluxes (nmol/m d, /unol/rn d) during the investigation period. [Pg.384]

For Pb, decreasing EF values (91, 50, 25) were observed between December 1999 and November 2000 in the trap material. As Pb is mainly directly associated not only with Al but also to a weaker extent with organic material, this result was probably due to the dilution effect with particles of mainly biological origin produced during spring and summer and the [Pg.385]
