Atmospheric deposition of chlorinated organophosphate flame retardants (OFR) onto soils
Atmospheric Environment(2012)
摘要
This study highlights the influence of dry and wet deposition on concentrations of chlorinated organophosphate flame retardants (OFR) in soil. Soil samples were collected in 2010/11 during a period of snow falling to snow melting, a period of rainfall and a dry period. Snow and rainwater samples were also collected from the soil sampling site. Tris(2-chloroethyl)phosphate (TCEP), tris(2-chloroisopropyl)phosphate (TCPP) and tris(1,3-dichloro-2-propyl)phosphate (TDCP) were analysed in soil samples using a combination of Twisselmann extraction and solid-phase microextraction (SPME), followed by gas chromatography-mass spectrometry (GC-MS). SPME/GC-MS was applied to analyse TCEP, TCPP and TDCP in aqueous samples.
