“…So DDTs in rice mainly come from growing environment, residual DDT characteristics of rice can represent its DDT existing condition. The studies show that (DDD+DDE)/DDT is regarded as standard whether there are new DDT input, if (DDD+DDE)/DDT > 1, the DDT degrade completely almost and no new pollution input; if (DDD+DDE)/DDT< 1, shows that there is new DDT pollution input [7,14]. The results shown in Fig.…”

“…Organochlorine pesticide once was used in large qualities in China, the usage of organochlorine pesticide per acre was 250g, it is about 60g per acre higher than US, harvest was brought to us, as well as potential dangers [5,6]. Although the production and usage of organochlorine pesticides such as DDT, BHC are forbidden, further study found that the residual DDTs in various soils, biological bodies and agricultural productions, it also is found in human milk [7], even it is traced in the polar biological bodies [8], the researches show that the current status of residual DDTs is not optimistic.…”

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.

The Ordos Basin is an important intracontinental sedimentary basin in western China for its abundant Mesozoic crude oil resources. The southern part of the Tianhuan Depression is located in the southwestern marginal area of this Basin, in which the Jurassic and Triassic Chang‐3 are the main oil‐bearing strata. Currently, no consensus has been reached regarding oil source and oil migration in the area, and an assessment of oil accumulation patterns is thus challenging. In this paper, the oil source, migration direction, charging site and migration pathways are investigated through analysis of pyrrolic nitrogen compounds and hydrocarbon biomarkers. Oil source correlations show that the oils trapped in the Jurassic and Chang‐3 reservoirs were derived from the Triassic Chang‐7 source rocks. The Jurassic and Chang‐3 crude oils both underwent distinct vertical migration from deep to shallow strata, indicating that the oils generated by Chang‐7 source rocks may have migrated upward to the shallower Chang‐3 and Jurassic strata under abnormally high pressures, to accumulate along the sand bodies of the ancient rivers and the unconformity surface. The charging direction of the Jurassic and Chang‐3 crude oils is primarily derived from Mubo, Chenhao, and Shangliyuan, which are located northeast of the southern Tianhuan Depression, with oils moving toward the west, southwest, and south. The results show that an integration of biomarker and nitrogen‐bearing compound analyses can provide useful information about oil source, migration, and accumulation.
