Irrigation of willow and poplar short-rotation coppice with landfill leachate is an increasingly interesting treatment option. Minimal leaching to groundwater and disturbance to plant growth must be ensured, but in such systems, where various site-specific factors interact, a case-specific approach is needed to determine potential hazards. This paper compares the effect of leachate irrigation on willow grown in clay lysimeters and poplar grown in sand lysimeters. Leachate irrigation increased willow biomass production, but not that of poplar. Near-zero nitrate-N concentrations were found in drainage water for both species after 2years of irrigation. Ability to retain total N and P, and TOC was relatively high for willow, taking into account the large amounts supplied, and better than for poplar. To reduce environmental risks the irrigation load should be reduced, but if leachate concentrations are reduced, the irrigation load can be as high as 6mm/day.

In the present study, leachate toxicity of a municipal solid waste landfill located in the Sinos River Valley region (southern Brazil) was evaluated using plant bioassays. Leachate toxicity was assess...
Raw and treated landfill leachate samples were collected from 5 municipal landfill sites in China to measure the concentrations and contamination profile of perfluoroalkyl acids (PFAAs) in leachate du...
An experiment was carried out to investigate the performance of mixed ocean bacteria, isolated from the ocean sediment, on landfill leachate treatment. In this treatment, ocean bacteria were the only ...
The article studies the detection of the leakage passage of leachate in a waste landfill dam. The leachate of waste landfill has its own features, like high conductivity, high chroma and an increasing...
This work reports the treatment of a mature landfill leachate through the application of chemical-based treatment processes in order to achieve the discharge legal limits into natural water courses. F...

This study aims to explore whether the increased supply of dietary plant sterols and plant stanols have any influence on serum levels of phytosterols and on consistency of carotid atheroma...
This randomized controlled double-blind intervention study unravels influence of dietary plant sterols and stanols on the structure and the sterol composition of the human aortic valve. Th...
Isolated minority communities in China use traditional plant-based methods of mosquito control. This study is evaluating 4 plants used in this way by monitoring mosquitoes entering houses...
This study investigates the effect of margarines supplemented with plant sterol esters on serum and cardiovascular tissue concentrations of plant sterols. We assume that consumption of mar...
The construction or arrangement of a task so that it may be done with the greatest possible efficiency.
Plant-derived ribosome-inactivating protein (RIP) purified from the Chinese medicinal herb tian-hua-fen which is obtained from the root tubers of Trichosanthes kirilowii. It has been used as an abortifacient and in the treatment of trophoblastic tumors. GLQ223 (Compound Q), a highly purified form of trichosanthin, has been proposed as antiviral treatment for AIDS.
Reducing staff to cut costs or to achieve greater efficiency.
Withholding or withdrawal of a particular treatment or treatments, often (but not necessarily) life-prolonging treatment, from a patient or from a research subject as part of a research protocol. The concept is differentiated from REFUSAL TO TREAT, where the emphasis is on the health professional's or health facility's refusal to treat a patient or group of patients when the patient or the patient's representative requests treatment. Withholding of life-prolonging treatment is usually indexed only with EUTHANASIA, PASSIVE, unless the distinction between withholding and withdrawing treatment, or the issue of withholding palliative rather than curative treatment, is discussed.
The state of weariness following a period of exertion, mental or physical, characterized by a decreased capacity for work and reduced efficiency to respond to stimuli.
