“…However, the correlation between the concentrations of the two major types of residues (p,p 0 -DDE and RPCBs) was only significant in adipose tissue after excluding red fox from the analysis. This shows some divergence in red fox from the expected association between these two types of global contaminants usually observed in Spanish biota (Guitart et al, 1996;Mateo et al, 1998Mateo et al, , 1999Mateo et al, , 2004Mañosa et al, 2003;Piqué et al, 2006). As can be observed in Fig.…”

Briefly, 1 g of liver was homogenized with 9 g of sodium anhydrous sulfate in a mortar.…”

“…Except for cyclodienes such as endrin and dieldrin that are completely lost in the clean-up step, the recovery of all analyzed compounds ranged from 79.1% to 107.5%. Recoveries with liver and adipose tissue samples with this method were >74% (Mateo et al, 1998). Corrections based on recovery data were not taken into account for quantification.…”

Levels of organochlorine pesticides and polychlorinated biphenyls in the critically endangered Iberian lynx and other sympatric carnivores in Spain

Accumulation of organochlorine compounds is well studied in aquatic food chains whereas little information is available from terrestrial food chains. This study presents data of organochlorine levels in tissue and plasma samples of 15 critically endangered Iberian lynx (Lynx pardinus) and other 55 wild carnivores belonging to five species from three natural areas of Spain (Doñana National Park, Sierra Morena and Lozoya River) and explores their relationship with species diet. The Iberian lynx, with a diet based on the consumption of rabbit, had lower PCB levels (geometric means, plasma: <0.01 ng mL(-1), liver: 0.4ngg(-1) wet weight, fat: 87 ng g(-1)lipid weight) than other carnivores with more anthropic and opportunistic foraging behavior, such as the red fox (Vulpes vulpes; plasma: 1.11 ng mL(-1), liver: 459 ng g(-1), fat: 1984 ng g(-1)), or with diets including reptiles at higher proportion, such as the Egyptian mongoose (Herpestes ichneumon; plasma: 7.15 ng mL(-1), liver: 216 ng g(-1), fat: 540 ng g(-1)), or the common genet (Genetta genetta; liver: 466 ng g(-1), fat: 3854 ng g(-1)). Chlorinated pesticides showed interspecific variations similar to PCBs. Organochlorine levels have declined since the 80s in carnivores from Doñana National Park, but PCB levels are still of concern in Eurasian otters (Lutra lutra; liver: 3873-5426 ng g(-1)) from the industrialized region of Madrid.

“…In a previous study with nestling great tits, we illustrated the relatively low contamination with OCPs, such as HCB and p,p ′‐DDT, at the selected study sites [19]. Also, in adult great tits, concentrations of pesticides in fat are low compared with concentrations found in mallards (HCB, 299 ng/g wet wt) [22] or in other waterbirds (HCB, 15–173 ng/g lipid wt) [23]. Additionally, PBDEs could not be measured in feathers, probably because of their low levels, as evidenced by the lower levels in fat of great tits compared to the concentrations reported in cormorants (PBDE 47, 59‐3,450 ng/g lipid wt) [9].…”

Keratinous tissues of mammals and humans, such as hair, have been used to determine the exposure to polychlorinated biphenyls (PCBs) and organochlorine pesticides. In the present study, we investigated the accumulation of persistent organic pollutants (POPs; PCBs, p,p'-DDT, p,p'-dichlorodiphenyldichloroethane [DDD], p,p'-dichlorodiphenyldichloroethylene [DDE], hexachlorobenzene [HCB], oxychlordane, trans-nonachlor, polybrominated diphenyl ethers, and polybrominated biphenyls [PBBs]) in feathers of the great tit (Parus major). The accumulation of POPs in feathers and fat samples of 27 adult great tits collected in April 2000 and December 2002 was compared with regard to possible temporal and spatial differences. Polybrominated diphenyl ethers, PBBs, trans-nonachlor, and HCB could not be quantified in feathers. Most PCB congeners and DDTs (p,p'-DDE, p,p'-DDD, and p,p'-DDT) could be determined in feathers, although concentrations in feathers were markedly lower (sigmaPCB concentration range, 28.2-87.1 ng/g) than concentrations in fat (sigmaPCB concentration range, 1244-10074 ng/g). Feathers had relatively higher levels of low-chlorinated PCBs (tetra- and pentachlorinated biphenyls) and p,p'-DDD compared to levels in fat, presumably reflecting levels in blood. Persistent organic pollutant concentrations did not increase with the age of the feather, suggesting that exogenous or aerial depositions of POPs onto the feather surface had no, or only minimal, influence on levels in feathers. For almost all compounds studied, POPs in feathers and fat were significantly positively correlated in samples collected during the breeding season but not in samples collected during the winter. This temporal difference may have been caused by seasonal changes in lipid reserves. Although further research is required, feathers appear to be a promising new, nondestructive biomonitor for PCBs and DDTs in avian wildlife.
