| utilization of the seagrass posidonia oceanica to evaluate the spatial dispersion of metal contamination. | metal concentrations have been measured in blades of the endemic mediterranean seagrass posidonia oceanica, along transects from three different contaminant point sources (the former asbestos mine of canari - corsica, france; the chemical plant of solvay/rosignano - livorno, italy; and the industrial harbour of porto-torres - sardinia, italy). the aim of this study was to evaluate the spatial extent of the impact of these sources in terms of metal contamination. the results showed that metal con ... | 2009 | 19081604 |
| posidonia oceanica: a tracer of past mercury contamination. | the aim of this study is to assess the relevance and the potential of posidonia oceanica as a tracer of past mercury contamination. shoots were collected on two sites, an impacted site, rosignano (tuscany, italy), and a pristine site, tonnara (corsica, france). lepidochronology was used to measure mercury concentrations in living sheaths and in the corresponding dead sheaths. the results show that there is an overestimation of mercury concentrations in dead sheaths (because of the degradation of ... | 2007 | 17240020 |
