Abstract Insecticide fingerprinting technique enables the detection and location of DDT and HCII residues in vegetables through the development of green and Prussian blue colors respectively. Cut vegetables are pressed against o‐tolidine impregnated paper and exposed to sunlight where colored spots appear instantly. The studies on 18 vegetable varieties revealed the pesticide residues and their distribution in different tissues. This direct method is sensitive (0.3 μg for HCII & 0.5 μg for DDT) and has special applications in quality control laboratorios and food industry. 相似文献
