Seaward, MRD 1980: The use and abuse of heavy metal bioassays of lichens from environmental monioring. - In: J. Spaleny (ed.): Proceedings of the Thrid International Conference, Bioindicatores Deteriorisationis Regionis. . Adademia, Praha pp. 375-384.

Abstract: 1 figure. [The author points out "... that only thalli within a limited range of sizes should be chosen for any monitoring programme involving bioassay, since (a) the heavy metal content is proportional to surface area (and therefore the age of the thallus), and (b) the measruements of uptake should reflect as near as possible the immediate past ambient environment."]
