The purpose of this paper is to selectively review the literature on
the thin-layer chromatography (TLC) and high-performance thin chromatography
(HPTLC) of pesticides, metabolites, breakdown products, and
some related agrochemicals published and/or abstracted in the period from
mid-2002 through mid-2004. It updates the previous review on this topic
[1] in a series dating back to 1982. Pesticide analysis remains one of the
leading applications of TLC and HPTLC for qualitative and quantitative
analysis of foods and crops [2]; environmental samples such as soil, drinking
water [3], and sand [4]; forensic and medical samples [5]; biological samples;
and commercial formulations. In addition, TLC is very widely used in
a variety of pesticide studies, such as determination of quantitative structure–activity
relations (QSAR) that describe how the molecular structure,
in terms of descriptors (lipophilic, electronic, steric), affects the biological
activity of a compound
