Web12 okt. 2004 · 2− concentrations were higher near the continent. This suggests that nss-SO4 2− concentrations were regionally influenced by anthropogenic sulfur input, because the distribution of nss-SO4 2− was similar to that of Rn-222 used as a tracer of continental air masses. Open Advanced Search Log in Web16 jun. 2002 · The nss-SO4 2− concentration was 178-421 ng m −3 , with an average of 285 ± 71 ng m −3 (Fig. 2d) and approximately 88% (median value) present in the fine-mode aerosols.
