On the other hand, UV detection and diode-array detection
(DAD) have been widely used as classical detectors in LC (Table 4),
although FLD was also applied for the analysis of mesotrione TPs
[17]. In general, detection wavelengths range from 210 to 280 nm.
In all the cases it can be observed that low detection limits were
obtained for a wide range of pesticides. For instance, carbamates
TPs can be determined in urine by UV detection using a detection
wavelength of 210nm [97]. Because at this wavelength, most of
the organic and inorganic compounds can absorb, some interfering
compounds can also be detected and efficient extraction and cleanup
techniques should be used in order to minimise interferences.
At the same wavelength a TPs of deltamethrin (3-phenoxybenzoic
acid, 3-PBA) [58] was detected, although it also presented signifi
cant absorbance at 230 nm. The sensitivity was four times higher at
210nmand although there was a considerable increase in the background
absorbance with respect to 230 nm, 210nm was selected
in order to carry out toxicokinetic studies. Furthermore, acetonitrile
and phosphoric acid was selected for the mobile phase in
order to reduce the background. However, for the determination of
other TPs, (***N-demethylspinosyn***, 2-aminobenzimidazole), higher
detection wavelengths can be used, increasing the selectivity of
the detection procedure [76,83].
