Adamo P., Vingiani S. & Violante P. (2002): Lichen-rock interactions and bioformation of minerals - Developments in Soil Science, 28: 377–391

This chapter discusses the principal effects of lichen growth on mineral substrata and focuses on rock surface disintegration, on mineral etching patterns and decomposition features, and on the formation of biogenic minerals. The chapter discusses the principal effects of lichen growth on mineral substrata with reference to rock surface disintegration, mineral etching patterns, and formation of oxalates, iron oxides, and hydroxides, aluminosilicates, and lichen acid–metal complexes. The release … EndNote Read more...

This paper presents the results of a bioaccumulation study of trace elements in the Naples urban area based on the use of the moss Sphagnum capillifolium (Ehrh.) Hedw. and the lichen Pseudevernia furfuracea (L.) Zopf exposed in bags in 23 sites. Moss and lichen bags were exposed for 4 months starting from the beginning of July 1999. Bags gathering was carried out after 10 weeks of exposure, at the end of the dry season, and after 17 weeks, during the wet season. The elements Al, As, Ca, Cd, Cr, Co, … EndNote Read more...

Adamo P., Crisafulli P., Giordano S., Minganti V., Modenesi P., Monaci F., Pittao E., Tretiach M. & Bargagli R. (2007): Lichen and moss bags as monitoring devices in urban areas. Part II: trace element content in living and dead biomonitors and comparison with synthetic materials - Environmental Pollution, 146: 392-399

Lobes of the lichen Pseudevernia furfuracea (L.) Zopf and shoots of the moss Hypnum cupressiforme Hedw. were subjected to different treatments (water washing, oven drying, HNO3 washing, NH4-oxalate extraction) to assess the influence of vitality on accumulation efficiency, during a 6-week exposure in bags in two Italian cities, Trieste and Naples. No trend emerged between treatments, in terms of accumulation ability, for major and trace elements. Only water-washed lichens showed an increased C and … EndNote Read more...

Adamo P., Colombo C. & Violante P. (1997): Iron oxides and hydroxides in the weathering interface between Stereocaulon vesuvianum and volcanic rock - Clay Minerals, 32: 453-461

The nature and composition of the Fe minerals in the rusty ferruginous material frequently located in the zone of contact between the thallus of Stereocaulon vesuvianum and the leucite bearing rock of Mt. Vesuvius have been studied by microscopic and submicroscopic investigations (SEM, TEM with EDXRA) complemented by X-ray diffraction and chemical analysis. Ferrihydrite is likely to be the main component of the short-range order iron oxyhydroxide pool, although the possibility that significant … EndNote Read more...

Adamo P., Arienzo M., Pugliese M., Roca V. & Violante P. (2004): Accumulation history of radionuclides in the lichen Stereocaulon vesuvianum from Mt. Vesuvius (south Italy) - Environmental Pollution, 127(3): 455-461

"Capsule": Elimination of radionuclides accumulated by the lichen Stereocaulon vesuvianum appears to be a slow process. The fruticose lichen Stereocaulon vesuvianum, growing on the slopes of Mt. Vesuvius (south Italy), was used as a biomonitor of 134Cs, 137Cs, 103Ru and 106Ru derived from the April 26 1986 Chernobyl nuclear reactor accident. Samples were taken at five different quotes (370, 490, 580, 780 and 960 m a.s.l.) and four successive dates (October 1986, December 1986, October 1987 and May … EndNote Read more...
