Polychlorinated dibenzo-p-dioxins and dibenzofurans in background air in China

摘要：

Air Samples were collected in China 11 background area. High volume samplers (Echo PUF, Italy) with a size-selective inlet for collecting only those particles smaller than 10 micrometers diameter were used to sampling air. The samples were analyzed by HRGC-HRMS after preparation. Concentrations of total 2,3,7,8-substituted PCDD/Fs were in the range of 134 -23374 fg/m3 with an average of 2850 fg/m3. Total 2,3,7,8-TCDD toxic equivalents (TEQs) calculated based on the WHO TEFs for air ranged from 0.4 -10.6 fg/m3.
