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。
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 tobaccogrowing 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/g）. 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.
