The demand for assessing both the variability of risk areas and the intensity of pollutant load rates on pesticide transferring to waters in China has been increasingly vigorous in recent decades. Therefore, to explore the transport of linuron with rainfall and irrigation in canopy-soil systems, an integrated pesticide transport modeling system has been selected and verified for simulating the three-phase linuron environmental fate in an orange field of the Three Gorges Reservoir (TGR) area. Results demonstrate that spatio-temporal distributions of linuron in surface soil primarily depend on its properties, rainfall, irrigation, and its applications; the peak levels of linuron in subsurface and deep soil are closely related to the cumulative and delayed effects. The findings may be used for policy supporting of soilwater- crop-pesticide management in an agricultural field of the TGR area. [ABSTRACT FROM AUTHOR]

The article investigates the morphology and physiology of a bacterial strain YZ2 isolated from the digested sludge of Sibao wastewater treatment plant in Hangzhou, China. Based on to the results of 16S rDNA phylogenetic analysis, biochemical tests, Vitek identification system and electron microscopy, the isolate was identified as Rhodococcus sp isolate YZ2, which is capable of dimethyl phthalate (DMP) biodegradation under nitrate- reducing conditions. It was also found out the isolate can degrade DMP from 101.14 mg to undetectable level within seven days, with the DMP biodegradation half-life of 1.45 days.

As the global energy market undergoes profound changes with price of oil reaching record highs and China emerging as a major force in world energy and global energy geo-politics, a debate on what has been described as ‘China energy threat’ seems to be gaining ground in western strategic circles. However, this is an illusion that is now somewhat exaggerated and overrated. As a matter of fact, the effect of the United States on global energy security affairs is far greater than that of China, and Washington is also not always the defender of the energy security as it claims to be.
