Regression equation Correlation coefficient 10 × LOD
Pyrethroid & Standard Concentration (ppb)
Permethrin cis y = 0.0002x + 0.0003 r2 = 0.999 0.012
Permethrin trans y = 0.0021x -9 × 10-5 r2 = 0.996 0.22
Fenvalerate cis Y = 0.0517x + 0.0237 r2 = 0.997 4.4
Fenvalerate trans Y = 0.0117x + 0.02094 r2 = 0.998 0.85
Cyfluthrin Y = 0.01344x - 0.0024 r2 = 0.995 1.4
Cypermethrin Y = 0.0046x + 0.0351 r2 = 0.998 0.69
Deltamethrin Y = 0.0718x - 0.1909 r2 = 0.997 4.3
Mirex, Standard Y = 0.02175x + 0.4717 r2 = 0.998 0.85
