Uptake and transformation of phenols by duckweed (Lemna gibba)
Phenol and its derivatives are common constituents of numerous natural and synthetic chemicals including pesticides. As a consequence of anthropological activities, a portion of them may reach various water bodies as contaminants which will have a great impact on the aquatic environment including biota. Aquatic plants are known to be one of the major habitants and food for many species and henc...
متن کاملDevelopment of a test system for homeopathic preparations using impaired duckweed (Lemna gibba L.).
OBJECTIVES A bioassay with arsenic-stressed duckweed (Lemna gibba L.) was developed to study potentially regulative effects of homeopathic preparations. We compared potentized substances (nine different potency levels between 17 x and 33 x ) with two controls (unsuccussed and succussed water) regarding their influence on number- and area-related growth rate and color of fronds (leaves). Screeni...
متن کاملGrowth response of Lemna gibba L. (duckweed) to copper and nickel phytoaccumulation Effet de l’accumulation de Cu et Ni sur la croissance de Lemna gibba L. (lentilles d’eau)
To assess the tolerance and phytoaccumulation ability of the duckweed Lemna gibba L. to copper (Cu) and nickel (Ni), the aquatic plants were exposed to different concentrations of Cu and Ni (0.1 – 2.0 mg/L) in quarter Coïc and Lesaint solution at pH = 6.0 (± 0.1) and under a daily regime of 12 h light. Copper and nickel were tolerated by L. gibba at concentrations ≤ 0.3 mg/L and ≤ 0.5 mg/L, res...
متن کاملPotential of Duckweed (Lemna minor) for Removal of Lead from Wastewater by Phytoremediation
This investigation was undertaken to study Pb uptake by small free floating aquatic plant Lemna minor from wastewater polluted by contaminated with heavy metals. Metal accumulation process was affected by various parameters such as different pH, temperature and concentration of Pb solution. Total chlorophyll contents in Lemna minor was adversely affected from increased with increasing Pb concen...
متن کاملEffect of copper on the toxicity and genotoxicity of cadmium in duckweed (lemna minor L.).
We investigated interactions between copper (in the concentrations of 2.5 μmol L-1 and 5 μmol L-1) and cadmium (5 μmol L-1) in common duckweed (Lemna minor L.) by exposing it to either metal or to their combinations for four or seven days. Their uptake increased with time, but it was lower in plants treated with combinations of metals than in plants treated with either metal given alone. In sep...
