SD	0.00122	0.00183	0.00285
LODa (SD × 3)	0.00366	0.00549	0.00855
LOQa (SD × 10)	0.01219	0.01828	0.02851

^aLOD and LOQ were estimated by using SD × 3 and SD × 10, respectively.

^bData for CTX1B were obtained after subtraction of the blank value. The sample studied was the R. snapper spiked at 0.03 µg/kg.
