Carbendazim [methyl benzimidazol-2-ylcarbamate] (Fig. 1) is a
broad-spectrum benzimidazole fungicide which is widely used in
agriculture for protecting and eradicating of a variety of pathogens
affecting fruits, nuts, vegetables, turf, and field crops. It is also used
in post-harvest food storage and as a seed pre-planting treatment.
Carbendazim is either applied directly to the soil, or sprayed over
the crop fields [1,2]. The benzimidazolic ring of this compound is
difficult to break and its degradation is slow, consequently it can
persist for a long time in the environment. Therefore, determination
of trace amount of this residual in water, soil, and various
crops has become increasingly important for the environment and
health protection [3]
