RESULTS<br />
Distinctive features in protein patterns from low and high phenol samples<br />
were highlighted. Differences in specific spot presence/absence, between the two<br />
phenol con<strong>di</strong>tions, were always found: some spots were exclusively expressed in<br />
low phenol rhizomes and others are exclusively expressed in high phenol ones.<br />
Heavy metal/element content<br />
The protocol to quantify five elements (Cu, Zn, As, Cd and Pb) has been<br />
developed for P. oceanica rhizomes and leaves, seawater and se<strong>di</strong>ment samples in<br />
2009 from S. Marinella meadow.<br />
in table 3.3.<br />
Metal/element content in the se<strong>di</strong>ments and in the water column is reported<br />
Table 3.3. Element concentrations in se<strong>di</strong>ment (µg/g) and water column (µg/l) collected in<br />
proximity of the S. Marinella meadow. The mean values of duplicates with standard deviations<br />
less than 5 ppb are reported.<br />

Mean metal/element content in leaves and rhizomes are reported in fig. 3.5,<br />
showing separately nonessential and essential elements. Values were homogeneous<br />
among the 20 <strong>di</strong>fferent samples in the meadow.<br />
