【摘要】 分析了中国2003—2005年2816份烤烟样品含氯农残总量在不同产区、不同品种、不同等级和不同年份间的变异,结果表明:中国烟叶含氯农残总量在样品间存在广泛的变异,变幅为0.00～5.40mg/kg,平均值为0.372mg/kg,变异系数为223.38%,有350个烟叶样品未检出,占总样品数的12.43%。其中云南(0.781mg/kg)、湖南(0.663mg/kg)烟叶样品的含氯农残总量较高,辽宁(0.037mg/kg)、四川(0.041mg/kg)烟叶样品的含氯农残总量较低;烤烟品种G80样品的含氯农残总量(0.599mg/kg)较高,9717品种样品的含氯农残总量(0.033mg/kg)较低;不同等级烟叶含氯农残总量表现为C2F>B2F>C3F>X2F;不同年份的烟叶含氯农残总量表现为2003年>2005年>2004年。针对中国烤烟含氯农残的状况,提出了控制烤烟农残含量、提高烟叶安全性的主要措施。更多还原

【Abstract】 2816 samples from 2003 to 2005 were used as materials to analyze the status of the total content of the residues of pesticides with chlorine in flue-cured tobacco leaves of China among different tobacco-growing areas,different cultivars,different grades and different years.The results indicated that the total content of the residues of pesticides with chlorine in tobacco leaves showed a big variation among samples,with the range of 0.00～5.40mg/kg,mean of 0.372mg/kg,and coefficient of variation of 223.38%.The residues of pesticides of 350 samples could not be detected as much as 12.43% of the total samples.The total contents of the of pesticides with chlorine in tobacco leaves at different locations were high for Yunnan(0.781mg/kg)and Hunan(0.663mg/kg),and were low for Liaoning(0.037mg/kg)and Sichuan(0.041mg/kg).The total contents of the residues of pesticides for different cultivars were high for G80(0.599mg/kg),and were low for 9717(0.033mg/kg).The contents of the residues of pesticides showed the trend of C2F > B2F >C3F > X2F for different grades,and the trend of 2003 > 2005 > 2004 for different years.According to the status of the residues of pesticides with chlorine in flue-cured tobacco leaves of China,some measures for controlling the residues of pesticides with chlorine and increasing security of tobacco leaves were suggested.更多还原
