Abstract

Thirty-one 24-h total suspended particulate (TSP) samples were collected at an urban site in Qingdao in December 2012. The total concentrations of eleven trace elements in the samples were determined as well as their water-extracted concentrations. The solubility was <5% (on average, the same definition is applicable for latter) for Fe and Al,~10% for Pb, Ba and Bi, 20%~30% for Cu, V, Cd and Mn; and~40% for Zn and As. The determination factors of the solubility were further studied, in terms of dust loading, the origins of aerosol, acid processing and weather conditions. In general, the obtained solubility was increased with decreasing dust loadings. Combining the results from the backward trajectory clustering analysis and the positive matrix factorization (PMF), the solubility of trace elements in TSP mainly originated from anthropogenic sources was found to be larger than the value in TSP originated from Asian dust. The same was true when secondary and marine aerosols were compared against soil-derived aerosols. Atmospheric acidification processes can increase the solubility, depending on aging extents. SO₄^2- and NO₃^- as well as the organic acids played a role in acidification processes. In addition, fog events apparently favored a higher solubility when comparing to haze events because of higher relative humidity therein.
