Effect of temperature on the uptake and metabolism of cyanide by weeping willows.

Plants' uptake and metabolism of cyanide in response to changes in temperature was investigated. Pre-rooted weeping willows (Salix babylonica L.) were exposed to hydroponic solution spiked with potassium cyanide for 2-3 d.

The potential for phytoremediation of iron cyanide complex by willows.

Hybrid willows (Salix matsudana Koidz x Salix alba L.), weeping willows (Salix babylonica L.) and hankow willows (Salix matsudana Koidz) were exposed to potassium ferrocyanide to determine the potential of these plants to extract, transport and metabolize this iron cyanide complex.

Response of weeping willows to linear alkylbenzene sulfonate.

Linear alkylbenzene sulfonate (LAS) is the most commonly used anionic surfactant in laundry detergents and cleaning agents. LAS compounds are found in surface waters and soils. The short-term acute toxicity of LAS to weeping willows (Salix babylonica L.

Detoxification of cyanide by woody plants.

Vascular plants possess an enzyme system that detoxifies cyanide by converting it to the amino acid asparagine. This paper examines the potential of three woody plants from the Salicaceae family to degrade cyanide. Pre-rooted trees were grown in carefully designed bioreactors with aqueous solution spiked with potassium cyanide at 23.

Phytotoxicity of cyanide to weeping willow trees.

Background: Cyanide is found predominantly in industrial effluents generated by metallurgical operations. It is an extremely toxic compound, so that problems and catastrophic accidents have recently occurred all around the globe. The goal of this study was to determine the toxicity of cyanide to a Chinese willow species, and to determine the removal capacity.

The effect of temperature on the rate of cyanide metabolism of two woody plants.

The response of cyanide metabolism rates of two woody plants to changes in temperature is investigated. Detached leaves (1.0 g fresh weight) from weeping willow (Salix babylonica L.

Metabolism of cyanide by Chinese vegetation.

Cyanide is a high-volume production chemical and the most commonly used leaching reagent for gold and silver extraction. Its environmental behavior and fate is of significant concern because it is a highly toxic compound. Vascular plants possess an enzyme system that detoxifies cyanide by converting it to the amino acid asparagine.

[Analysis of the constituents of essential oils from Sambucus chinensis].

26 chemical constituents of the essential oil from Sambucus chinensis Lindl. were separated and identified by GC/MS. The relative contents of them were determined by area nomalization.
