Optimized Multiresidue Analysis of Organic Contaminants of Priority Concern in a Daily Consumed Fish (Grass Carp)
Table 1
ANOVA and IST analysis of extracted PAHs, OCPs, PBDEs, and PCBs by EA/CH (1 : 1) (ES1), DCM/HEX (4 : 1) (ES2), and HEX/ACE (1 : 1) (ES3) in blank fish meat and spiked fish meat.
