Authors: Lv Yin Fei , Ren Yan Fang , Liu Dong , Zhang Yan Chao , He Jun Yu
Published: December 2014

Water management affects the bioavailability of cadmium (Cd) in the soil and hence their accumulation in rice and grain yields. A pot experiment was carried out to investigate the effects of different water managements (flooding, intermittent irrigation and aerobic) on rice yield and cadmium accumulation in rice plants growing on cadmium contaminated soil. The results showed that compared to the flooding and aerobic treatment, the intermittent irrigation increased grain yield by 7.55-29.58%, which contributed to the increase of seed setting rate and panicle number. Compared with the intermittent irrigation, aerobic treatment significantly increased Cd contents in roots, straw and grains, while flooding reduced the Cd contents in rice. Compared with flooding, both aerobic and intermittent irrigation enhanced Cd distribution in the root and reduced it in the straw and grain. With increasing irrigation from aerobic to flooded conditions, the soil available Cd concentrations decreased significantly. The patterns of soil pH change were just opposite to those of soil available Cd. Thus, intermittent irrigation could increase rice yield and also reduce Cd in the grain.

Published: December 2014

Based on methods of the fuel consumption, statistical and analogy analysis, the throughput amount method was established to calculate the emissions from port handling, and the minimum mileage method was established to estimate emissions from port cargo highway distributing. In the methods, some coefficients were used obtained by investigations: the current container handling emission factors of NOx, VOCs, CO, PM2.5 and SOx are 1.64, 0.21, 0.42, 0.01 and 0.29 t/TEU; the energy consumption of the unit throughput is 4.12 tons of standard coal per 104tons; the ratios of the unit non container cargoe handling energy consumption for coastal and inland river ports to those of container cargo are 0.631 and 0.405; the ratio of the unit non container cargoe highway distributing energy consumption to those of container cargo is 0.365. The calculation results show that the total emissions from the cargo handling and highway distributing of 2013 in China for NOx, VOCs, CO, PM2.5 and SOx are 54.365, 14.821, 24.631, 5.599 and 16.802 104tons, and the emissions from highway distributing are 4.21, 10.02, 8.24, 8.22 and 8.19 times of the emissions from port handling facilities. According to energy saving and emission reduction measures, formulas were established to calculate air pollutant emissions after the new added measures. Analyzing the real performance of the measures implemented since 2001 and predicting its trend of development, a scenario was designed, in which the Chinese port throughput continuously rises while the energy saving and emission reduction efforts gradually increase by 2020: the popularities of the energy saving measure of "oil changing to electricity" and the clean fuel measure of "oil changing to gas" reach 100% and 83%; the proportion of power plants with 95% desulfurization and denitrification reaches 100%; the energy saving and emission reduction efficiency of port cargo distributing optimization measures reaches 40%. Under this scenario, the prediction shows that during the port throughput increasing approximately 4.2 times from 2005 to 2020, the air pollutant emissions will be reduced significantly, returning to a lower level compared with 2005. The above methods and results can be used to support the decision-making and the implementation of emission reduction measures for the national, regional and port enterprises.

Authors: Fan Xue Zhong , Yang Guang Jie , Jia Zhi Rong , Zhao Qing Feng , Liu Xue Bo , Sun Na
Published: December 2014

Emissions of air pollutants from coal-fired power plants pose a threat to healthy living environment. Developing renewable energy and changing electricity generation structure dominated by coal-fired power has become a vital national strategy. In this paper, taking a rapidly urbanizing coastal area in southern Laizhou Bay of China as the study area, a scenario planning concerning substitution of wind power for coal-fired power in enterprise-owned power plants was conducted. Coupled with the electricity generation prediction by a grey prediction model GM (1, 1) and the calculation of pollutant emission intensity, we obtained three scenario schemes: no substitution (Scenario 1), low substitution (Scenario 2) and high substitution (Scenario 3). The results showed that Scenario 1 is not acceptable; Scenario2 is acceptable, but not ideal; Scenario 3 is optimal. The electricity generation structure under Scenario 3 has been radically converted from the type dominated by fossil fuel to one dominated by renewable energy, becoming an environment-friendly power generation framework with fairly low pollutant emission densities. This study can contribute to local managers to seek more concrete measures in mitigating the conflict between electricity demand and environmental health.

Authors: Kang Christina S. , Kim Han Seung
Published: December 2014

4-Chlorophenol is well-known as an extensively used antiseptic, and it may cause severe damage to the environment and human health. 4-Chlorophenol can be biologically degraded by Arthrobacter chlorophenolicus A6, which can be attributed to the cphC-I and cphB genes of the microorganism that encode for a two-component flavin-diffusible monooxygenase (TC-FDM), composed of oxygenase and reductase components. This study reports the cloning, overexpression, purification, and function analysis of the oxygenase and reductase components from the genes cphC-I and cphB. The genes were cloned into vector pET-24a, and 4 different strains of Escherichia coli were transformed with these recombinant genes. The optimization of expression conditions indicated that cphC-I is best overexpressed in E. coli BL21(DE3) incubated for 24 hours at 15°C with 0.5 mM of isopropyl-β-D-1-thiogalactopyranoside. However, cphB was not expressed into soluble form enzyme in any of the conditions, and therefore fre of E. coli was used instead to analyze the function of CphC-I. CphC-I was able to degrade approximately 13.86% of 4-chlorophenol, indicating that it is indeed a reduced flavin-dependent monooxygenase and utilizes 4-chlorophenol as a substrate. The results of this study are expected to establish the basic understanding of TC-FDM for its application to enzymatic bioremediation of phenol-contaminated environment.

Published: December 2014

The surface properties and performance of activated carbon (AC) used for catalytic ozonation were investigated after nitric acid modification (N-AC) and Cu (II)-loaded (N-Cu-AC). The results showed that the nitric acid modification could increase the amount of surface functional groups of AC. As a result, the adsorption capacity and catalytic activity of AC could be improved. The surface functional groups and Cu (II)-loaded of N-Cu-AC showed a synergistic effect on catalytic ozonation, where the catalytic activity of Cu (II)-loaded was more stable. N-Cu-AC was an effective and reusable catalyst for catalytic ozonation. The highest TOC removal efficiency of 58.0% could be achieved when N-Cu-AC was used for 60 min-catalytic ozonation treatment of acid red 3R.

The rigid nature of ramie hairiness on fabrics cause severe itching feeling, which limited the application of ramie fabrics requiring for direct contact to skin. Current modification methods for ramie fabrics are ineffective, expensive or harmful to the main body of fabric. In our research, a low temperature softening method for ramie fabrics in NaOH, urea, glycerol, and Na2B4O7 treatment bath was developed and proven to be efficient in lowering the stiffness and scratchiness of ramie fabrics without significant adverse effect on the fabric strength. Since it is possible to reuse the chemical agents, this treatment was relatively cheap and environmentally friendly.

Published: December 2014

The main objective of this study was to investigate membrane fouling caused by natural organic matter (NOM). Flux measurement, fourier transform spectroscopy (FTIR), scanning electron microscopy (SEM) were employed to compare the surface morphology of fouled membrane and chemically cleaned membrane. Sodium hypochlorite (NaClO), sodium hydroxide (NaOH), hydrochloric acid (HCl) were used as chemical cleaning agents respectively. Flux analysis demonstrated that chemical cleaning have little effect on flux recovery. FTIR spectrometry revealed that polysaccharide and protein took the major responsibility for membrane fouling. SEM showed that foulants filled the pores and blocked the membrane surface which led to the flux decline.

Authors: Du Jian Fen , Tang Yu Lin , Li Qian
Published: December 2014

Anabaena sp. and M. aeruginosa were used to examine the toxic mechanism of nanoZnO to them, as well as the toxicity. Typical chlorophyll fluorescence parameters, including effective quantum yield, photosynthetic efficiency and maximum electron transport rate, were measured by a pulse amplitude modulated fluorometer. Results showed that nanoZnO could inhibit Anabaena sp. and M.aeruginosa growth with the EC50 (concentration for 50% of maximal effect) of 0.74±0.01 and 1.68±0.01 mg/L respectively. The toxicity of nanoZnO to Anabaena sp. is higher than that to M.aeruginosa, which can be proved by the malondialdehyde content in Anabaena sp. and M.aeruginosa cells.
