Air-biomonitoring by transplanted lichens in the Negev Desert, Israel

Abstract

The present report summarizes tow time periods of study: 1) August 1997 - April 1998, 2) May 1999 - November 1999. 1) In August 1997 thalli of the lichen Ramalina maciformis (Del.) Bory were collected in the Negev Desert and transplanted with their substrate, flintstones, to 24 biomonitoring sites in the Negev Desert. In April 1998 the lichens were retrieved and their elemental content was determined by ICP-AES. In addition, we examined physiological parameters as presented in report no.1. 2) In May 1999 thalli of the lichen were collected in the control site and transferred together with the substrate to 10 biomonitoring sites in the Negev. These thalli were retrieved in November 1999. We examined: a) the electric conductivity, indicative of cell membrane integrity; b) the production of ethylene indicative of stress; c) the chloropkyll a fluorescence as a means to monitor aspects of photosystem II (PSII) activities in the lichen. Final results of the first period experiment show that lichens exposed to air contaminants at a site of toxic waste deposition, accumulated large amounts of Al, Ba, Ca, Cu, Fe, Mg, Na, Pb, S, Sr and Zn. Preliminary results of the second period of exposure show that physiological parameters,  More>>
