“…In summary, OCP and PCB concentrations were greater in cardinal eggs from urbanized areas near WDC than rural areas, but concentrations were generally low. These results are consistent with recent reports (Mora et al 2016;Maldinado et al 2016) indicating that concentrations of OCPs and PCBs in passerine and other resident and migratory birds have declined in recent decades. Nevertheless, concentrations were higher than most in some nests and the within-neighborhood variability was much greater than we expected, indicating that the neighborhoods and nearby areas are not uniformly contaminated.…”

Northern Cardinal eggs from six neighborhoods near Washington DC were analyzed for organochlorine pesticides and PCBs. All compounds were detected more frequently and at higher concentrations in more heavily urbanized neighborhoods. DDT (mostly as p,p'-DDE) was detected in all neighborhoods. p,p'-DDT was typically 0.5‒16 ng/g (ww) in most suburban neighborhoods but was not detected (< 0.1 ng/g) in more rural areas; however, p,p'-DDT was 127‒1130 ng/g in eggs from two suburban Maryland nests and comprised 65.7% of total p,p'-DDT isomers in the most contaminated sample, indicating recent exposure to un-weathered DDT. Total chlordane (sum of 5 compounds) was 2‒70 ng/g; concentrations were greatest in older suburban neighborhoods. Total PCB (sum of detected congeners) was < 5‒21 ng/g. Congener patterns were similar in all neighborhoods and resembled those typical of weathered mixtures. Results indicate that wildlife remains exposed to low concentrations of legacy contaminants in suburban neighborhoods and that cardinal eggs can be used to monitor localized contamination.

“…Such sampling would involve the collection of internal organs such as the liver, muscle or brain (Falkowska et al 2016;Roscales et al 2011). Eggs are an alternative to destructive sampling (Elliott et al 2005;Moore and Tatton 1965;Mora et al 2016;Peck et al 2016), but when certain species of birds lay a single egg per season, care should be taken to make sure such species would relay. Non-destructive sampling techniques became necessary and feathers started being used as a proxy for contamination levels in internal organs (Jaspers et al 2007;Jaspers et al 2011;Van den Steen et al 2007).…”

Persistent organic pollutants (POPs) are chemical compounds of environmental concern due to their toxic, persistent nature and their ability to bio-accumulate in biological tissue. Seabirds, for often being at the top of the food web, have been used as monitors of environmental pollutants. Adverse effects caused by POPs have been reported in common terns (Sterna hirundo) since the 1970s. Egg shell thinning, embryo and hatchling deformities have been reported for this species. Environmental legislation, such as the Oslo-Paris Convention (OSPAR), has agreed on the monitoring of concentration of POPs in common terns. This study set out to investigate contemporary concentrations of polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), organochlorine pesticides (OCPs) and brominated flame retardants (BFRs) in common terns breeding in Ireland, along with congener profiles. Investigation was conducted in live (n = 15) and dead birds (n = 20) to test for the efficiency of different methodologies using preen oil and feathers versus liver and preen gland. Mean concentrations of POPs followed the order: PCB (36.48 ng/g ww feather) > PAH (30.01 ng/g ww feather) > OCP (13.36 ng/g ww feather) > BFR (1.98 ng/g ww feather) in live birds; and PAH (46.65 ng/g ww preen gland) > PCB (44.11 ng/g ww preen gland) > OCP (15.15 ng/g ww liver) > BFR (5.07 ng/g ww liver) in dead birds. Comparison of contaminant results with toxicity pre-established levels concluded that this population of common terns in Ireland is not at risk of anomalies caused by POPs. However, some levels are higher in comparison to the ones established by OSPAR's EcoQO and must be monitored periodically.

“…Thus, some of them began to spend more time in more contaminated lower latitude regions and to act as vectors of contamination to less polluted areas (Borgå et al, 2022;Ramp et al, 2015;Storrie et al, 2018). Species that spend longer periods than usual feeding at southern latitudes are probably increasing their exposure to these substances, as it has been already reported for some seabird species (Bustnes et al, 2010;Elliott et al, 2021;Mora et al, 2016).…”
