Soil and sediment Determination of polychlorinated dibenzo-p-dioxins(PCDDs)and polychlorinated dibenzofurans(PCDFs)Isotope dilution HRGC-HRMS

This standard is formulated for the purpose of implementing the Environmental Protection Law of the People's Republic of China, protecting the environment, safeguarding people’s health, and regulating the determination of Polychlorinated Dibenzo-p-Dioxin (PCDDs) and Polychlorinated Dibenzofurans (PCDFs) in soil and sediment. This standard provides the isotope dilution HRGC-HRMS for determination of Polychlorinated Dibenzo-p-Dioxin (PCDDs) and Polychlorinated Dibenzofurans (PCDFs) in soil and sediment. This standard is an amendment to Determination of Polychlorinated Dibenzo-p-Dioxins and Polychlorinated dibenzo-p-furans by Isotope Dilution HRGC/HRMS (HJ/T 77-2001). It shall replace the requirements in HJ/ T77-2001 on the determination of Polychlorinated Dibenzo-p-Dioxin (PCDDs) and Polychlorinated Dibenzofurans (PCDFs) in soil and sediment, as of the day it goes to effect. This standard shall apply to the analysis of Polychlorinated Dibenzo-p-Dioxin (PCDDs) and Polychlorinated Dibenzofurans (PCDFs) in environmental surveys on nationwide regional soil background, farmland soil environment, soil impact assessment of construction projects, soil pollution accidents, as well as river, lake, and sea sediments.
