“…Interestingly, this level is about tenfold greater than the highest values reported for other higher plants (Edwards, 1983). Lemna also has a high uptake capacity for ionic contaminants including metals (Ti, Cu, Sr, Zn, Mo, As) in both field and laboratory situations (Mangi et al, 1978;Rodgers et al, 1978;Clark et al, 1981;Frick, 1985). Once again, assimilation is rapid; metals can equilibrate in Lemna within hours (Clark et al, 1981;Muir et al, 1985).…”

“…Because the Lernnaceae rapidly assimilate exogenous chemical, they have been found to be a sensitive indicator of herbicide strength (Damanakis, 1970;Mattoo et al, 1984;Hughes et al, 1988). The toxicity of heavy metals has also been studied extensively with Lemna, with the interesting result that the plants are relatively resistant to these elements (Mangi et al, 1978;Rodgers et al, 1978;Clark et al, 1981;Frick, 1985).…”

Although higher plants represent a significant portion of the total biomass in some aquatic environments, their use in ecosystem evaluation has lagged behind that of other organisms. This is partly due to a lack of convenient aquatic higher plant systems that can be employed for ecotoxicological assessment. However, the aquatic C-3 monocot Lemna gibba has many attributes that makes it useful for ecosystem health assessment. In this report, using examples from the literature and our research, some of the applications Lemna has for environmental research are discussed. Toxicant impacts on Lemna can be readily assessed in terms of growth; the plants multiply quickly and changes in biomass (which doubles approximately every 2 days) can be accurately measured by counting leaves. The plants are small, allowing for simultaneous multiple replication. The small size also makes the lighting conditions easy to control; sunlight can be accurately simulated and specific spectral regions can be enhanced or deleted. Lemna is amenable to in vivo chlorophyll and photosynthesis assays, which make excellent companion endpoints for growth. The plants assimilate chemicals directly from the growth medium, facilitating controlled toxicant application. Furthermore, Lernna has a high bioconcentration capacity, indicating a potential for use in bioremediation technologies.

“…Effects were most pronounced in water of a low alkalinity _isler 1985). Common duckweed (Lemna minor) is the most sensitive aquatic plant tested exhibiting reduced growth in water containing 10 ppb hexavalent chromium (Mangi et al 1978). The LC50s for aquatic macrophytes range between 2.5 and 25 mg/L (Mangi et al 1978).…”

“…Conway (1978) found that 2 mg/l Cd limited the growth of algae at population level, and 10 mg/l Cd also inhibited the growth at population level in a one-day exposure. The toxic effects of Cr on algae have been reported by Mangi et al (1978). According to Nakanishi et al (2004) Achnanthes minutissima has a tolerance to copper ion.…”

Accumulation of heavy metals (Cd, Pb, Hg, Cr) in water and plankton of Sarıyar Dam Lake (SDR) was seasonally studied from April, 2000 to December, 2004. In addition, seasonal changes in phytoplankton and zooplankton populations and species abundance were also determinate. Some physio-chemical parameters of water and their correlation with heavy metals were also determinated. The dominant phytoplanktonic algae determined were Choroococcus,
