| posidonia oceanica as a historical monitor device of lead concentration in marine environment. | we show that posidonia oceanica is able to reliably monitor the variability of environmental lead (pb). we analyze lead concentration measured in the scales and rhizomes of posidonia oceanica collected in seven sites along the coasts of the sicily island and subsequently fractioned them according to a lepidochronological analysis. we measure lead concentration in posidonia oceanica tissues by using the flame atomic absorption spectrophotometry technique. we compare the measured lead concentratio ... | 2005 | 15926545 |
