Abstract. Concentrations of several trace elements were determined in mosses, higher plants and organs of small mammals from a geothermal area in Tuscany (central Italy). Increased deposition of Hg, As, B, and Sb was detected in biological samples collected within a few hundred meters of geothermal power plants. Among the species considered, the moss Hypnum cupressiforme was the most efficient accumulator of trace elements. Contamination levels in a fodder-plant (Hedysarum coronarium) and… Expand
The impacts of geothermal power plant emissions on terrestrial ecosystems in contrasting bio-climatic zones
Exploitation of geothermal energy is considered to have minimal ecological impacts. However, this assumption has not been widely studied. We tested the hypothesis that emitted elements fromExpand

Use of native mosses as biomonitors of heavy metals and nitrogen deposition in the surroundings of two steel works.
TLDR
A biomonitoring survey using the moss species Hypnum cupressiforme Hedw was conducted in the surroundings of two steel plants, showing an appreciable influence of the NW prevailing winds of the region in the dispersion of pollutants, as well as a clear decreasing gradient in the concentrations of metals in mosses within a distance of 1500 meters from the facilities.

Oak leaves as accumulators of airborne elements in an area with geochemical and geothermal anomalies.
TLDR
Compared to the composition of epiphytic lichens andepigeic mosses from the same sites in the Colline Metallifere, the elemental composition of Q. pubescens leaves was less affected by element contributions from adsorbed soil particles, and was thus easier to evaluate atmospheric inputs of elements in oak leaves than in cryptogams.

The environmental distribution of mercury and other trace elements in the geothermal area of Bagnore (Mt. Amiata, central Italy) and its surroundings was evaluated by means of lichens used asExpand
Black pine (Pinus nigra) barks as biomonitors of airborne mercury pollution.
TLDR
Preliminary results indicate that bark Hg concentrations are comparable with values reported for lichens in the same areas, suggesting that tree barks may represent an additional useful tool for biomonitoring of airborne Hg. Expand

Biomonitoring with epiphytic lichens as a complementary method for the study of mercury contamination near a cement plant
TLDR
The study showed that selected lichens could be used to detect low to moderate Hg emissions from a cement plant and that the biomonitoring procedure could be further standardized and used as part of an environmental monitoring programme. Expand

TLDR
It is concluded that lichens are reliable bioindicators of geothermal pollution, with values for species richness and IAP rising with distance from geothermal installations, and air pollution arising fromGeothermal emissions is responsible for the zonation shown. Expand
