本文对食品有机氯残留量测定实验室取样原则进行了研究探讨。结果证明有机氯农药残留在水果中的分布为:果皮>果籽>果核>果肉。其量为:果皮中六六六残留量相当于果肉的57.47倍;果籽浓度相当于果肉的41.80倍;果核相当于果肉的1.76倍。三种不同方法的取样,六六六,DDT残留量分析结果,经统计学处理有显著性差异。 In this paper, the principle of sampling laboratory for determination of organochlorine residues in food was studied. The results showed that the distribution of organochlorine pesticide residues in fruits was: peel> fruit seed> fruit core> pulp. The amount of residues in the peel is 57.47 times that of the flesh; the fruit seed concentration is equivalent to 41.80 times of that of the flesh; and the flesh is equivalent to 1.76 times of the flesh. Three different methods of sampling, BHC, DDT residue analysis results, statistically significant difference.
