Bioaccumulation Potential and Physiological Responses of Aquatic Macrophytes to Pb Pollution
In view of their potential bioaccumulation of heavy metals, Ceratophyllum demersum and Myriophyllum spicatum was studied under hydroponic cultures enriched by different Pb concentrations (25, 50, 75 mg/l) for 1–7 days. Both species exerted remarkable capabilities to concentrate Pb in their tissues as compared to control. The highest accumulation value of Pb (164.26 mg/g.dw) was recorded in C. demersum and ...

The response of some common Egyptian plants to ozone and their use as biomonitors
Relative sensitivity of five common Egyptian plant species namely, _Senecio vulgaris, Malva parviflora, Sonchus oleraceus_, _Medicago sativa_ and _Melilotus indicus_ to elevated levels of ozone has been studied. The plants were exposed to charcoal filtered air (CFA) and different levels of O3 (50 and 100 ppb) for 5 h per day. The studied parameters were recorded for five consecutive days ... Read more
