Four pilot-scale test mesocosms were conducted for the remediation of organochlorine pesticides (OCPs)-contaminated aged soil. The results indicate that the effects on degradation of hexachlorocyclohexanes (HCHs) and dichlorodiphenyltrichloroethanes (DDTs) were in the following order: nutrients/plant bioaugmentation (81.18 % for HCHs; 85.4 % for DDTs) >(More)
Treatment experiments by two laboratory scale semi-batch reactors and a demonstration scale process were both carried out to evaluate endocrine disrupting chemical removal characteristics by ozonation in sewage treatment. In the semi-batch mode experiments, secondary effluent and primary effluen of sewage treatment plants were ozonated respectively.(More)
Ozonation has been considered to be an effective means for the reduction of excess sludge in recent years. However, it remains largely unknown whether hydrophobic organic micro-pollutants, which are originally adsorbed on activated sludge, will be released into wastewater upon ozonation because of sludge solubilization. This study investigated the(More)
The decomposition of endocrine-disrupting chemicals (EDCs) including estrone (E1), 17beta-estradiol (E2), estriol (E3), nonylphenol (NP), and bisphenol A (BPA) during ozonation of municipal sewage grabbed from the outlets of primary sedimentation tanks was studied through laboratory-scale experiments. A newly developed in vitro bioassay called nuclear(More)
BACKGROUND Aphids are insect pests with significant importance worldwide for agricultural and horticultural crops. The chemical pesticides used to control aphids could result in pesticide residues in agricultural and horticultural products as well as in negative effects on the environment. Therefore, alternative control methods are urgently needed. This(More)
Little is known about the contamination level of antibiotics in swine wastewater in China. The highly complex matrix of swine wastewater, which generally has a chemical oxygen demand (COD) concentration as high as 15,000 mg/L, makes it difficult to detect antibiotics at trace levels. In this work, a highly selective and sensitive analytical method was(More)
BACKGROUND The choice for instrumentation with minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) in treatment of degenerative lumbar disorders (DLD) remains controversial. The goal of this study was to investigate clinical outcomes in consecutive patients with multi-segment DLD treated with unilateral pedicle screw (UPS) vs. bilateral(More)
Fusion proteins of a protease inhibitor from an entomopathogenic nematode symbiotic bacterium (PIN1) and green fluorescent protein (GFP) were expressed in tobacco (Nicotiana tobacum cv. Samsun NN). The PIN1-GFP protein expressed under the control of the CaMV-35S promoter was detected in leaves of transgenic tobacco plants. The effect of PIN1 on anti-pest(More)
—This paper considers the problem of multiple disjoint sources localization using time difference of arrivals (TDOA) and frequency difference of arrival (FDOA) with sensor position and velocity errors. By exploiting the observation that the multiple disjoint sources exhibit the same sensor location errors, the influence of sensor location errors can be(More)
The electro-Fenton (E-Fenton) treatment of landfill leachate concentrates was investigated in this study. The concentrates were generated from nanofiltration of biologically pretreated landfill leachate, and contained high concentrations of refractory organics and inorganic salts. During the E-Fenton treatment, H(2)O(2) was electrochemically produced at a(More)
