英文摘要	用气相色谱-电子捕获器法测定了北京郊区某养鸡场不同生长期的饲养鸡的肌肉、表皮、肝脏、胃、心脏以及鸡蛋、饲料和粪便中HCH的残留浓度.分析结果表明,饲养鸡体内肌肉、表皮、肝脏、胃和心脏的∑HCH湿重浓度分别为(0.35±0.37)、(3.91±2.52)、(1.78±1.26)、(1.00±0.85)和(1.35±0.75)ng/g,脂标化浓度分别为(64.3±171)、(19.6±7.33)、(64.9±27.2)、(74.5±74.1)和(17.8±4.42)ng/g,远低于国家<食品中农药残留最大限量>标准.肝脏∑HCH脂标化浓度显著高于其他器官,而未观察到HCH各异构体残留水平在肌肉、表皮、心脏与胃之间具有显著差别.除饲料、胃和粪便内各HCH异构体成分中以δ-HCH为主外,β-HCH是鸡体内与鸡蛋中残留最高的异构体.β-HCH在鸡体内各器官都体现出富集的特性,肝脏对除δ-HCH以外的3种异构体也都体现出显著的富集特性.对成年绿柴鸡(雄)和绿壳蛋鸡(雌)样品中HCHs残留水平的对比分析显示,雄性较雌性具有更强的HCHs富集能力.; The concentrations of hexachlorocyclohexane isomers (HCHs) in muscle, skin, liver, stomach, heart, eggs, feed and feces of chicken from a poultry farm were determined by GC-ECD. The residue level of total HCHs (SigmaHCHs) in muscle, skin, liver, stomach and heart were (0.35 +/- 0.37), (3.91 +/- 2.52), (1.78 +/- 1.26), (1.00 +/- 0.85), (1.35 +/- 0.75) ng/g (wet weight), while the lipid normalized concentrations were (64.3 +/- 171), (19.6 +/- 7.33), (64.9 +/- 27.2), (74.5 +/- 74.1), (17.8 +/- 4.42) ng/g, respectively,which are far lower than the Maximum Residue Limits for Food in China. Among all tissue samples, the highest lipid-normalized concentration was observed in the liver and no significant differences were observed among other organs. delta-HCH was the predominant isomer in chicken feed, stomach and faces, while beta-HCH owned the highest concentration in all other samples. beta-HCH was enriched in muscle, skin, liver, stomach and heart, while alpha-HCH and delta-HCH were also enriched in liver. Significant difference was revealed between male and female chicken in terms of bioaccumulation, indicating higher bioaccumulation ability of the former.; 国家自然科学基金; 国家重点基础研究发展计划(973计划); PubMed; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 0; 1; 207-211; 29
