Metal cations (Ni and Cu), thiol\u2013rich reagents (glutathione, ammonium pyrrolidinedithiocarbamate) and some chelating agents (EGTA, EDTA at pH 9\u00b75 or pH 2\u00b77) were ineffective or caused membrane damage. Disodium EDTA at pH 4\u00b75 was found to be an effective displacing agent, although the Na caused some release of intracellular K without membrane damage. This displacement procedure showed that no Pb suppliedin the laboratory entered the protoplast in 2 h. The effect of Ca, Cu, Pb, and Sr on membrane integrity was investigated.<\/jats:p>","DOI":"10.1006\/lich.1994.1007","type":"journal-article","created":{"date-parts":[[2002,9,18]],"date-time":"2002-09-18T21:49:32Z","timestamp":1032385772000},"page":"83-90","source":"Crossref","is-referenced-by-count":74,"title":["A Method for Studying the Cellular Location of Lead in Lichens"],"prefix":"10.1017","volume":"26","author":[{"given":"C.","family":"Branquinho","sequence":"first","affiliation":[]},{"given":"D.
