Toxicity of manufactured nano-ZnO to Lemna minor
… the aquatic, primary producer lesser duckweed (Lemna minor), and the mechanism of toxicity was analysed. Both short-term (one week) and long-term (six weeks) toxicity of nano-ZnO (uncoated) were determined. Results show that the toxicity of nano-ZnO added to the aquatic growth medium increases …

Waste remediation and value creation: the recovery of nutrients from dairy industry wastewater using the aquatic plant Lemna minor
… which was assessed in this thesis using aquatic Lemnaceae, i.e. duckweed. Accordingly, environmentally polluting compounds, such as N and P, are removed from the wastewater by plant action and in duckweed a valuable biomass is created which can be used as a feed or biofuel. In general, it was …

Preference and Performance of the Water Lily Aphid (Rhopalosiphum Nymphaeae) among Native and Invasive Duckweeds (Lemnaceae)
… variety of host plants including members of the Lemnaceae family. Many studies have focused on the relationship between herbivore preference and performance on different host plants, and as such the goal of this study was to determine if there is any relationship between host plant preference and …
