Understanding the spatial distribution and apportioning the sources of water pollution are important in the study and efficient management of water resources. In this work, we considered data for 13 water quality variables collected during the year 2004 at 46 monitoring sites along the Qiantang River (China). Fuzzy comprehensive analysis categorized the data into three major pollution zones (low, moderate, and high) based on national quality standards for surface waters, China. Most sites classified as "low pollution zones" (LP) occurred in the main river channel, whereas those classified as "moderate and high pollution zones" (MP and HP, respectively) occurred in the tributaries. Factor analysis identified two potential pollution sources that explained 67% of the total variance in LP, two potential pollution sources that explained 73% of the total variance in MP, and three potential pollution sources that explained 80% of the total variance in HP. UNMIX was used to estimate contributions from identified pollution sources to each water quality variable and each monitoring site. Most water quality variables were influenced primarily by pollution due to industrial wastewater, agricultural activities and urban runoff. In LP, non-point source pollution such as agricultural runoff and urban runoff dominated; in MP and HP, mixed source pollution dominated. The pollution in the small tributaries was more serious than that in the main channel. These results provide information for developing better pollution control strategies for the Qiantang River. © 2009 Elsevier Ltd. All rights reserved.

Phytolacca americana L. (pokeweed) is a promising species for Cd phytoextraction with large biomass and fast growth rate. To further understand the mechanisms involved in Cd tolerance and detoxification, the present study investigated subcellular distribution and chemical forms of Cd in pokeweed. Subcellular fractionation of Cd-containing tissues indicated that both in root and leaves, the majority of the element was located in soluble fraction and cell walls. Meanwhile, Cd taken up by pokeweed existed in different chemical forms. Results showed that the greatest amount of Cd was found in the extraction of 80% ethanol in roots, followed by 1M NaCl, d-H2O and 2% HAc, while in leaves and stems, most of the Cd was extracted by 1M NaCl, and the subdominant amount of Cd was extracted by 80% ethanol. It could be suggested that Cd compartmentation with organo-ligands in vacuole or integrated with pectates and proteins in cell wall might be responsible for the adaptation of pokeweed to Cd stress. © 2010 Elsevier B.V.

The present study was conducted to investigate the levels and sources of heavy metals (Cu, Cr, Cd, Pb, Zn, Hg and As) and persistent organic compounds including polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) in soils taken from Wenling, an emerging e-waste recycling city in Taizhou, China. The results suggested that most heavy metals exceeded the respective Grade II value of soil quality standards from State Environmental Protection Administration of China and also exceeded the Dutch optimum values. Total PAHs in soil ranged from 371.8 to 1231.2 μg/kg, and relatively higher PAHs concentrations were found in soils taken from simple household workshops. PCBs were detectable in all samples with total concentrations ranging from 52.0 to 5789.5 μg/kg, which were 2.1-232.5 times higher than that from the reference site (24.9 μg/kg). Results of this study suggested soil in the Wenling e-waste recycling area were heavily contaminated by heavy metals, PAHs and PCBs. Furthermore, compared with large-scale plants, simple household workshops contributed more heavy metals, PAHs and PCBs pollution to the soil environment, indicating that soil contamination from e-waste recycling in simple household workshops should be given more attention. © 2009 Elsevier B.V.

Effects of different chemical oxygen demand (COD) to nitrate concentration ratios in the injected leachate on the denitrification capacity of landfilled municipal solid waste were evaluated. Results showed that the 6-year-old refuse possessed high denitrification capacity. The nitrate reduction rate increased with the increasing COD concentration in the injected leachate. When the initial COD concentration increased to 6500mgl -1, nitrate reduction rate could reach up to 6.85mgNO 3 --Nl -1h -1. At the initial biodegradable COD/NO3--N ratio lower than the stoichiometric ratio of heterotrophic denitrification, autotrophic bacteria was the dominant microbial communities for denitrification. With the increase of COD/NO 3 --N ratio, the primary functional denitrifier would shift from autotrophic Thiobacillus denitrificans to heterotrophic Azoarcus tolulyticus. These results suggested that the initial biodegradable COD/NO 3 --N ratio in the injected leachate should be adjusted to higher than 6.0 for rapid in situ denitrification of 500mgNO 3 --Nl 3 -1. © 2011 Elsevier Ltd.

The 50th anniversary of the first hologram made with laser light is an appropriate time to shine some light on the lasers that made it possible. Dubbed "a solution looking for a problem", the laser emerged from industrial research labs as a new kind of light source for any application requiring coherence. Immediately commercialized by both start-up and well-established corporations, lasers sold in their first year of production left much to be desired but made a good first impression. Their second year of production saw technical improvements that met the requirements for practical holography, and by the end of 1963 were good enough to make holograms of three dimensional, deep and diffuse imagery. Mostly obsolete by the end of the 1960s, very few of the Kennedy era lasers have survived. This survey is intended to identify and celebrate them, so more may be preserved as they are found, to be admired in the future. © Published under licence by IOP Publishing Ltd.
