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 کامل: examining l2 teachers’ corrective feedback types in relation to learners’ uptake, proficiency levels, and context types
abstract this study investigates the teachers’ correction of students’ spoken errors of linguistic forms in efl classes, aiming at (a) examining the relationship between the learners’ proficiency level and the provision of corrective feedback types, (b) exploring the extent to which teachers’ use of different corrective feedback types is related to the immediate types of context in which err...
Growth 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 کاملToxic Effects of Nickel Oxide Bulk and Nanoparticles on the Aquatic Plant Lemna gibba L.
The aquatic plant Lemna gibba L. was used to investigate and compare the toxicity induced by 30 nm nickel oxide nanoparticles (NiO-NPs) and nickel(II) oxide as bulk (NiO-Bulk). Plants were exposed during 24 h to 0-1000 mg/L of NiO-NPs or NiO-Bulk. Analysis of physicochemical characteristics of nanoparticles in solution indicated agglomerations of NiO-NPs in culture medium and a wide size distri...
