Cadmium is the most common toxic metal threatening safe rice supply. Rice straw has the potential to remove Cd from large-scale effluent contaminated by heavy metals since it exhibited a short biosorption equilibrium time of 5 min, high biosorption capacity (13.9 mg g(-1)) and high removal efficiency at a pH range of 2.0-6.0. The main Cd biosorption(More)
Beijing city, capital of China, has experienced a rapid urban expansion over the past two decades due to accelerated economic growth. The fast urban spatial expansion has led to the substitution of the natural vegetation-dominated land surfaces by impervious materials. This has a significant impact on the ecosystem on a local to global scale. Therefore, a(More)
Strain A54(T) was isolated from rhizospheric soil of turf grasses irrigated with reclaimed water in Taoranting Park, Beijing, China. Phenotypic, chemotaxonomic and polygenetic analyses established the affiliation of the isolate to the genus Dyadobacter. Strain A54(T) possessed 97.7, 94.4 and 94.7 % 16S rRNA gene sequence similarity with respect to the type(More)
INTRODUCTION The most reliable liver safety signal in a clinical trial is considered to be 'Hy's Law cases' defined as subjects experiencing hepatocellular injury and serum bilirubin elevations with no more likely cause than study drug. However, there is little published data to support the current biochemical criteria for Hy's Law cases or their use to(More)
Urban tree species mapping is an important prerequisite to understanding the value of urban vegetation in ecological services. In this study, we explored the potential of bi-temporal WorldView-2 (WV2, acquired on 14 September 2012) and WorldView-3 images (WV3, acquired on 18 October 2014) for identifying five dominant urban tree species with the(More)
Wetland plant rhizosphere microorganisms play a significant role in the purification of ecological restoration of reclaimed water replenishment wetlands. In this study, water quality discriminant analysis indicated the wetland had a distinctive role in the purification of total nitrogen (TN), total phosphorus (TP), and nitrate (NO3 −) from reclaimed water,(More)
Plants can effectively remove airborne particles from ambient air and consequently improve air quality and human health. The accumulation of particles on the leaf surfaces of three plant species with different epicuticular wax ultrastructures, such as thin films, platelets and tubules, was investigated during leaf expansion in Beijing under extremely high(More)
The objective of this paper is to investigate the sensitivity of reflectance to the variation in biochemical and biophysical variables at leaf, canopy, and regional scales using a modeling approach. The results show that, at the leaf scale, the variations in chlorophyll a+b content, the leaf structure parameter, and the water content dominate the(More)
