In various samples of Mytilus galloprovincialis, 210Po was determined by alpha-spectrometry while Mn, Fe, Ni, Cu, Zn, Cd, Sn, Hg and Pb by energy dispersive, polarised X-ray fluorescence spectrometry (EDPXRF). The mussels of different sizes were taken from 7 sites in the central Adriatic Sea along the Marche coastal region during the four seasons of the year. 210Po activity concentration ranged between 57 and 343 Bq·kg-1 dry weight. The concentration ranges of heavy metals (μg·g-1 dry weight) were as follows: Mn: 72.9-83.1; Fe: 45.1-754; Ni: 1.3-7.6; Cu: 17.9-156; Zn: 60.9-189; Cd: 0.6-1.0; Sn: 0.6-3.9; Hg always <0.5; Pb: 2.0-9.0. The data obtained depend upon the site and the period of the sampling and they are also compared with those obtained by other authors for the same organism in the Mediterranean and other Italian seas.

Abstract
In various samples of Mytilus galloprovincialis, 210Po was determined by alpha-spectrometry while Mn, Fe, Ni, Cu, Zn, Cd, Sn, Hg and Pb by energy dispersive, polarised X-ray fluorescence spectrometry (EDPXRF). The mussels of different sizes were taken from 7 sites in the central Adriatic Sea along the Marche coastal region during the four seasons of the year. 210Po activity concentration ranged between 57 and 343 Bq·kg-1 dry weight. The concentration ranges of heavy metals (μg·g-1 dry weight) were as follows: Mn: 72.9-83.1; Fe: 45.1-754; Ni: 1.3-7.6; Cu: 17.9-156; Zn: 60.9-189; Cd: 0.6-1.0; Sn: 0.6-3.9; Hg always <0.5; Pb: 2.0-9.0. The data obtained depend upon the site and the period of the sampling and they are also compared with those obtained by other authors for the same organism in the Mediterranean and other Italian seas.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
