Elemental and isotopic compositions in blank filters collecting atmospheric particulates

Abstract Background The atmospheric particulates can be harmful to human health due toxic substances sorbed onto particulates. Although the have been collected using different types of filters, few studies reported background contents major and trace element, isotopic compositions in blank filters used for collecting yet. Here, we first report elements, (Zn Pb isotopes) filters. Then, evaluate best type filter elemental isotope analyses Findings elements are lowest PTFE become higher order Nylon, NC, GF indicating that either and/or Nylon most suitable element analysis Likewise, much is Otherwise, result overestimating their concentrations All ? 66 Zn JMC-Lyon values two within those from samples Chinese deserts Loess Plateau. 206 Pb/ 204 ratios similar with Xi’an Beijing, not study Conclusions This suggests cannot source identification isotopes.
