Comments: The absolute values of molar absorptivity coefficients at 253.7 nm were determined according to
the Beer-Lambert law : 
epsilon = 381 ± 28 for alachlor,  
epsilon = 11240 ± 1030 for pendimethalin,  
epsilon = 22220 ± 1850 for propanil and  
epsilon = 5720 ± 410 for trifluralin (in units of M-1 cm-1).
