ASTM D7968-17a 采用液相色譜串聯質譜法(LC/MS/MS)測定土壤中多氟化合物的標準試驗方法的最新版本是哪一版?
最新版本是 ASTM D7968-23 。
5.1 This test method has been developed by the U.S. EPA Region 5 Chicago Regional Laboratory (CRL).
5.2 PFCs are widely used in various industrial and commercial products; they are persistent, bio-accumulative, and ubiquitous in the environment. PFCs have been reported to exhibit developmental toxicity, hepatotoxicity, immunotoxicity, and hormone disturbance. A draft Toxicological Profile for Perfluoroalkyls from the U.S. Department of Health and Human Services is available.7 PFCs have been detected in soils, sludges, and surface and drinking waters. Hence, there is a need for a quick, easy, and robust method to determine these compounds at trace levels in various soil matrices for understanding of the sources and pathways of exposure.
5.3 This method has been used to determine selected polyfluorinated compounds in sand (Table 4) and four ASTM reference soils (Table 5).
