| 지하수(음용) 중 석면분석방법 (석면광산 등 석면발생지역의 토양환경 관리지침) |
- 목적 : 지하수 중 석면의 특성을 관찰하여 정성과 정량분석을 하기 위한 것이다. - 적용범위 : 물시료 중의 석면분석에 사용되며 투과전자현미경으로 판단할 수 있는 석면의 정량범위는 길이가 10 μm를 초과하는 석면이며 허용가능 바탕시료의 범위는 0.01 MFL 이하이다. |

| ANALYTICAL METHOD FOR DETERMINATION OF ASBESTOS FIBERS IN WATER - US EPA-600/4-83-043(ANALYTICAL METHOD FOR DETERMINATION OF ASBESTOS FIBERS IN WATER) |
- This method is applicable to drinking water and drinking water supplies, and should be used when the best available analytical procedure is required. - The method determines the numerical concentration of asbestos fibers, the length and width of each fiber, and the estimated mass concentration of asbestos in the water. Fiber size and aspect ratio distributions are also determined. - It is beyond the scope of this document to provide detailed instruction in electron microscopy, electron diffraction, crystallography or X-ray fluorescence techniques. It is assumed that those performing this analysis will be sufficiently knowledgeable in these fields to understand the specialized techniques involved. - 원문 : US EPA 홈페이지 [http://www.epa.gov] |
| DETERMINATION OF ASBESTOS STRUCTURES OVER 10 μm IN LENGTH IN DRINKING WATER |
- US EPA-600/R-93-134(DETERMINATION OF ASBESTOS STRUCTURES OVER 10 μm IN LENGTH IN DRINKING WATER) - This test method is recommended for the determination of the presence and quantitation of asbestos structures in drinking water samples. The method allows for the quantitation of structures greater than 10 um in length. - This test method describes the equipment and procedures necessary for the sampling and analysis of drinking water by transmission electron microscope(TEM). - The identification of asbestos by TEM is based on (a) morphology, (b) selected area electron diffraction(SAED) and (c) energy dispersive x-ray analysis(EDXA). - 원문 : US EPA 홈페이지 [http://www.epa.gov] |
