Trace Element Bioaccumulation in Stone Curlew (Burhinus oedicnemus, Linnaeus, 1758): A Case Study from Sicily (Italy).

摘要: : The study aimed to highlight the degree of trace element contamination along three sites Sicily: Magnisi peninsula (MP), located in proximity Augusta-Priolo-Melilli petrochemical plant; Ragusa agro-ecosystem (RA), characterized by a rural landscape; and Gela plain (GP), intensive agriculture disused plant. We collected biological samples (abraded back feathers blood) Stone Curlew (Burhinus oedicnemus Linnaeus, 1758) as well soil determine elements concentrations As, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb, Zn, Se V using ICP-MS analysis. results found for show different trends accumulation, which depend on management geological characteristics areas. showed higher (As, Mn plain; Pb Hg peninsula). Nevertheless, no critical values were either environment-if are compared with legal limits fixed Legislative Decree No. 152/2006, approving Code Environment-or living organisms-if toxicological thresholds birds, especially if short-term exposure from blood considered. Only levels animal RA GP slightly than minimum level required bird diets. positive scenario can be attributed one hand interruptions emissions refinery around 5 years ago, other more intense strict controls that implemented area surrounding pole Augusta-Priolo-Melilli.
