Hazardous air pollutants Surveys

About the atmosphere of prefecture two spots, we investigate hazardous air pollutants once a month.

It is ... with hazardous air pollutants

"Thing causing atmospheric pollution with material which might spoil a person's health when is taken in continuously" (the Air Pollution Control Act extract)
In addition, 248 materials are appointed as material which may correspond to hazardous air pollutants.

In addition, of these, judging from hazardousness and the atmosphere environment density of material, 23 materials are appointed to priority approach material as material that it is thought that health risk is high.

 

Surveys point: General environmental two spots

     Saga-shi (the Saga station), Imari-shi (the Otsubo station)

 

Surveys item: It is 22 materials except dioxin among priority approach materials

     (1) Volatile organic compounds (VOC)

       Acrylonitrile, vinyl chloride monomer, methyl chloride, chloroform, 1,2-dichloroethane, dichloromethane,
       Tetrachloroethylene, trichloroethylene, toluene, 1,3-butadiene, benzene, ethylene oxide

     (2) Aldehydes

       Acetaldehyde, formaldehyde

     (3) Heavy metal

       Nickel compound, arsenic and compound, beryllium and compound, manganese and the compound,

       Chrome and trivalent chrome monster ※Hexavalent chromium compound ※Mercury and the compound

       (we measure for gross quantity of ※ chrome and the compound)

     (4) Benzo[a]pyrene

 

Surveys method:

(1) Volatile organic compounds (VOC)

 We gather in container called canister and measure with gas chromatograph mass spectrometer (GC/MS).

 Ethylene oxide samples to special adsorbent using low volume air sampler (LV) and measures in GC/MS.

(3) Heavy metal

 Nickel compound, arsenic and compound, beryllium and compound, manganese and the compound, the chromic and chemical compound,

 We sample on the filter paper using the high volume air sampler (HV) and measure with inductive coupling plasma mass spectrometer (ICP-MS).
 Mercury and the compound sample to special adsorbent using low volume air sampler (LV) and measure with mercurial measuring equipment.
