Net embodied petroleum importers face greater petroleum security risks in international trade due to their high foreign dependence. Therefore, paying better attention to the national flows and drivers of embodied petroleum consumption can effectively serve net embodied petroleum importers to avoid petroleum security risks and formulate environmental protection policy. This study utilized the multi-regional input–output model to determine the top five embodied petroleum net importers (i.e., the USA, Japan, Germany, the UK, and France) under the economic globalization, and traced the flows of embodied petroleum consumption through international trade. Combined with the logarithmic mean Divisia index method, this study also deeply investigated the drivers of changes embodied petroleum in net imports. The results show that from the perspective of international trade, the USA was not only the largest importer but also the largest exporter of embodied petroleum. Among the trade flows of embodied petroleum, the largest trade flow was from China to the USA, which indicated that China was the world factory and the USA was the consumer power. The embodied petroleum trade markets of Germany, the UK, and France was mainly distributed in Europe & Eurasia resulted from European economic integration. The largest contributor to the decrease of embodied petroleum imports in the top 4 net importers was the petroleum intensity effect. Meanwhile, the import dependence effect was the largest contributor to the increase of France’s embodied petroleum net imports. In order to further avoid the risk of petroleum security, it is an effective path worth exploring to construct the diversified petroleum product import strategy and improve energy efficiency.
Chlordane (1,2,4,5,6,7,8,8-octachloro-3a,4,7, 7a-tetra-hydro-4,7-methanoindane) is one of organochlorine pesticides (OCPs) which has been listed as one of the persistent organic pollutants (POPs) to be reduced and finally eliminated in the Stockholm Convention on Persistent Organic Pollutants, because of its great persistence, toxicity, bio-accumulation and long-range transport potential. It is critical to create a national chlordane usage inventories for China to compile chlordane emission inventories, which is helpful for carrying out risk assessments and other researches related to chlordane in China. The annual data of chlordane usage was calculated and modified in accordance with the reported annual production of chlordane which was caculated on the basis of the termite distribution, the data of chlordane usage rate and the annual new construction area (NCA).With the help of Geographic Information System, the usage data of this NCA were allocated to a grid system then, with a 1/4° longitude by 1/6° latitude resolution and a size for each grid cell of approximately 25 km by 25 km. Between 1988 and 2008, the total usage of chlordane in China was 2745 t, accounting for approximately 80% of the production in the same period. Zhejiang Province was the largest consumer of chlordane in China, whose usage adds up to 980 t, greatly exceeding other provinces/regions, followed by Jiangsu Province (534 t) and Sichuan Province (428 t). The region with the least usage of chlordane was Beijing. Provinces of Guizhou, Henan and Hebei did not use any chlordane, even though termites had occurred in these provinces. Gridded usage inventories showed that the intensive use of chlordane was concentrated in the southeast part of China, Yangtze River Delta and Pearl River Delta in particular. The satisfaction of the inventories was supported by the consistence between the estimated data of annual usage and the reported annual production of chlordane, and by the consistence between distribution pattern of chlordane’s usage and ambient air concentration. 相似文献
