The DDT Residual Current Status and Variance Analysis of the Early and Late Rice in the Jiangxi Province

Abstract:

Using the method of GC-ECD detect the residual DDT in the early and late rice from eleven cities of Jiangxi province. The results show that DDTs are detected both in the early and late rice. Residual DDT in early rice varies from 2.846μg/kg to 147.413μg/kg and the average level is 64.929μg/kg while to the late rice, residue is in the range of 26.900-163.920μg/kg and average level is 84.182μg/kg, the residual DDT in both of the two kinds of rice are under the limited value of national food hygiene standards. At the same time, there are big differences in different regions. The DDT’s coefficient of variation in early rice and late rice are 76.26% and 61.23% respectively. The industry makes a contribution to the different residual of DDT between early and late rice. Results also show that 60% of regions in Jiangxi province have new input of DDT，relevant departments should pay attention on it. Meanwhile, the new input of DDT in the early rice from Yingtan and late rice from Ji’an probably comes from atmospheric deposition or usage pesticides containing DDT.
