A long-term field experiment was designed to assess remediation efficiency and ecological risk of phytoremediation of Cd under different cultivation systems with or without ethylene diamine tetraacetic acid (EDTA). EDTA can significantly improve the phytoremediation effectiveness of a historically polluted e-waste dismantling site through enhancing Cd(More)
Due to the high threat to human health and the ecosystem from metals, the levels and distribution of As, Hg, Cr, Co, Ni, Cu, Zn, Cd, Pb, Mn, V, Sn, Sb, Li and Be in various layers of soil from an e-waste recycling area in Guiyu, China were investigated. The extent of pollution from the metals in soil was assessed using enrichment factors (EFs) and the(More)
OFDM (Orthogonal Frequency Division Multiplexing) has been widely used in modern wireless communications because of its high data rate, immunity to delay spread and frequency selective fading, high frequency spectral efficiency and other advantages. Besides these benefits, one of the main disadvantages is the PAPR problem. High PAPR will increase the system(More)
Guiyu is a well-known electronic waste dismantling and recycling town in south China. Concentrations and distribution of the 21 mineral elements and 16 polycyclic aromatic hydrocarbons (PAHs) collected there were evaluated. Principal component analyses (PCA) applied to the data matrix of PAHs in the soil extracted three major factors explaining 85.7% of the(More)
The phytoremediation efficiency of various metals by Ficus microcarpa was evaluated through a real scale experiment in the present study. The root biomass production of the species varied significantly from 3.68 to 5.43 g because of the spatial heterogeneity of different metals. It would take 4-93 years to purify the excess Cd of the experimental site.(More)
Previous studies have shown that phytoremediation usually requires soil amendments, such as chelates, to mobilize low bioavailability heavy metals for better plant absorption and, consequently, for remediation efficiency. A total dry biomass of 3.39 and 0.0138 kg per plant was produced by a phytoremediator, Eucalyptus globulus, and a nitrogen fixing crop,(More)
Soil samples containing excess Cd (0.82 mg kg-1), Pb (92.7 mg kg-1) and Cu (72.7 mg kg-1) relative to their corresponding safe thresholds (0.3, 80 and 50 mg kg-1, respectively) from a notorious e-waste disposing and recycling place in southern China were phytoremediated with EDTA addition to evaluate the promotion effects of cytokinin on the remediation(More)
PURPOSE To prospectively evaluate the short-term reproducibility of intravoxel incoherent motion (IVIM) parameters and apparent diffusion coefficient (ADC) in lung cancer patients. MATERIALS AND METHODS In all, 50 patients (50 lesions) underwent free-breathing diffusion-weighted imaging (DWI) (b = 0, 300, 800 s/mm2 ) and IVIM (10 b-values, 0-1000 s/mm2 )(More)
