摘要: AbstractThe total suspended particulate (TSP) samples over the Yellow Sea and East China were collected to determine major compositions of water-soluble ionic species during two cruises in autumn 2007. The aerosol exhibited an obvious regional variation between cruises, with higher concentrations (except Na+ Mg2+) northern first cruise. secondary ions [non–sea salt sulfate (nss-), , ] 11 ± 4.9, 3.1 2.1, 3.7 2.6 μg m−3, respectively, which together contributed 72% determined ion concentrations. Significant correlations these found within each sampling period, while nss-K+ nss-Ca2+ showed strong correlation other. calculated results equivalent anions (nss- ) cations ( Ca2+) that acidic mostly neutralized alkaline study areas. mass ratio nss-/ was ...
