Comparable precisions between the two instruments were achieved and trueness of the analysis results was confirmed. The CSIA-Cl method using GC-qMS was originally developed by Sakaguchi-S\\\"oder et al.and further improved by several relevant studies,and has been used to evaluate organic contaminant attenuation in the environment.
