Spectroradiometry was used to quantify changes in duckweed frond reflectance that occurred throughout the 400–850 nm spectrum under various ethylene glycol (EG) concentrations and exposure times. The threshold concentration of EG at which a reflect

Ethylene glycol is the major component of many antifreeze/coolant and deicant formulations. Its use as an aircraft/runway deicant ensures that it is a major but intermittent pollutant of surface waters in the vicinity of those airports where it is us

The toxicity of a series of chlorinated phenols, from phenol to pentachlorophenol, was determined using frond reproduction in aseptically grown Lemna gibba. The toxicities of the phenols tended to increase as the number of chlorine substituents on th

The toxicity of cadmium with regard to the vegetative reproduction of duckweed, Lemna gibba, grown in sterile culture, was determined. The EC50 was found to be 800 ppb. Duckweed grown in 2.24 ppm cadmium (supplied as cadmium nitrate) for 7 days accum
