HJ 742-2015 in English

本标准规定了测定土壤和沉积物中12种挥发性芳香烃的顶空/气相色谱法。
本标准适用于土壤和沉积物中12种挥发性芳香烃的测定。其它挥发性芳香烃如果通过验证也适用于本标准。
当取样量为2g时，12种挥发性芳香烃的方法检出限为3.0～4.7ug/kg，测定下限为12.0～18.8ug/kg，详见附录A。

Scope

This standard specifies a headspace/gas chromatography method for the determination of 12 volatile aromatic hydrocarbons in soil and sediments. This standard is applicable to the determination of 12 volatile aromatic hydrocarbons in soil and sediments. Other volatile aromatic hydrocarbons also apply to this standard if verified. When the sampling volume is 2G, the method detection limit of 12 volatile aromatic hydrocarbons is 3.0~4.7UG/KG, and the lower limit of determination is 12.0~18.8UG/KG. See Appendix A for details.
