Resum: Livers from 65 greater flamingos (Phoenicopterus ruber roseus) collected in three Spanish wetlands were analyzed for organochlorine (OC) residues and fatty acid (PA) composition. Some of these birds were lead poisoned (n=52), as determined in a previous study published elsewhere. The effects of OC levels and normal/abnormal lead levels on the PA composition were analyzed with ANOVA tests in order to establish possible influences among them. High lead concentration was found to increase the relative proportions of 16:0 and 18:1 n-9, and the decrease the proportions of 18:0, 18:2 n-6 and 20:3 n-6. Main OC residues in liver samples were highly chlorinated PCBs (range 211-17,289 ng/g wet weight) and pp' -DDE (11-10,268 ng/g WW), and it was determined that PCBs influenced positively the relative proportions of 18:0, 20:4 n-6 and 22:4 n-6, and negatively the 16:0 and 16:1 n-7 proportions. These results are discussed and compared with previously published data on the use of FAs as biomarkers of lead and OC exposure.
