Background Objectives

• Chemicals that caused Kanemi-yusho
• Designated as POPs(Persistent Organic
  Pollutants)
• Resident to degradation,Long transfer,High
  acuumulation in the ecosystem,Toxity
• Influences on the humans and the ecosystem has
  been concerned

PCBs (Polychlorinated Biphenyls)
We need to monitor the PCB concentration
carefully because PCB productions are stored in
many dispersed places.
Monitoring was carried out from 2000 to 2005 in
Hyogo prefecture inJapan.Regarding the sampling
location and period, sampling was carried out in
urban, industrial, rural area and collected
continuously for about one month.
PCB usage(t)
Daily variation of Dioxin Concentration(compared
with Hi volume air sampler and Low volume air
sampler)
Low volume air sampling method is effective for
long term monitoring.
Research method

• ?Monitoring was conducted at three points at
  Nishiwaki
• (rural area),Takasago(industrial area), Suma in
  Kobe
• (urban area) .
• ?PCB concentrations in each sample were
  determined with
• high resolution GC/MS (JEOL JMS700).
• GC/MS analysis The analysis was carried out
  using a HP 6890 gas chromatograph connected to a
  JMS-800D mass spectrometer (JEOL Ltd. Japan)
  operating at a resolution gt10 000. Co-PCB, Co-PXB
  and PXDF were analyzed using HT8-PCB column.
  Temperature program used for congener specific
  separation of the PCB, PXB and PXDF on HT8-PCB
  column 120C, 20C/min. to 180C, 2C/min. to 260C.
  5C/min. to 300C, 5 min. isothermal. Monitoring
  ions for GC/MS analysis are listed in Table.

• Standards Commercially-available native/labeled
  standards were obtained from CIL as authentic
  standard/mixtures for crosschecking the
  assignment. , 4-bromo- 3, 3, 4, 5-tetrachloro
  biphenyl was obtained from CIL for a PXB
  standard.
