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 کاملAnaerobic Co-Digestion of Duckweed (Lemna Gibba) and Waste Activated Sludge
In this study duckweed (Lemna gibba) and waste activated sludge (WAS) were co-digested in different proportions with acclimatized anaerobic granular sludge (AAGS) in mesophilic conditions. The aim was to evaluate if the co-digestion could lead to an increased efficiency of methane production compared to digestion of waste activated sludge alone. Results indicate that co-digestion with both duck...
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 کاملBoron removal by the duckweed Lemna gibba: a potential method for the remediation of boron-polluted waters.
Boron (B) is often found in polluted and desalinated waters. Despite its potentially environmental damaging effects, efficient treatments are lacking. The duckweed Lemna gibba has been shown to remove toxic elements from water; however, its applicability to B removal is unknown. In this study, L. gibba was examined for its tolerance to B in water and its B removal efficiency. Duckweed plants we...
