“…Mean lipid content was 5.8%-5.9% in eggs from AR and TP, the two most urbanized areas, and 8.2%-8.8% elsewhere. Lipid differences may reflect nutritional status/diet quality of the nesting females or egg age (Rattner et al 2016); however, the latter is unlikely considering that all eggs were in early developmental stages. Among-neighborhood differences for fresh egg mass, egg length, and egg width were not significant (p = 0.16-0.96).…”

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.

“…All eggs were infertile, i.e., with liquid contents and no embryo development, except for four eggs with partially developed embryos. Several studies have concluded that persistent compounds are not likely to be affected in their concentration by in ovo metabolization. , The eggs were weighed and measured upon collection in the field and kept at roughly 10 °C until transported to the laboratory in Denmark. They were immediately stored at −20 °C until they were opened, and their content was transferred to amber glasses.…”

Median levels of regulated flame retardants, i.e., polybrominated diphenyl ethers (PBDEs), brominated biphenyl (BB)-153, and hexabromocyclododecane (HBCD), in 33-48 eggs of peregrine falcons (Falco peregrinus) from Greenland were 1909, 359, and 5.98 ng/g lipid weight (lw), respectively, and generally intermediate to levels in North America and Europe. Unregulated flame retardants had lower median concentrations of 1.06 (2-ethylhexyl-2,3,4,5-tetrabromobenzoate, EH-TBB), 2.42 (1,2-bis(2,4,6-tribromophenoxy)-ethane, BTBPE), 0.52 (2,4,6-tribromophenyl 2,3-dibromopropyl ether, DPTE), and 4.78 (dechlorane plus) ng/g lw. Although these compounds are often described as recent replacements for PBDEs, they were also present in eggs from the 1980s. BDE-209 was the only compound with a significant increase (+7.2% annual change) between 1986 and 2014, while BB-153 and DPTE decreased significantly (-8.0% and -2.8% annual change, respectively). Dechlorane plus showed a nonsignificant increase. Individual birds, equipped with light-logging geolocators, confirmed the contaminant exposure over a large geographical area as the birds spent nearly equal time periods in their breeding and wintering grounds in Greenland and Central/South America, respectively, interrupted by 5-6 weeks of migration through North America.

“…In addition to the six editorials, nine retrospectives were prepared by past Bulletin authors, or associates, with papers in the top 100 citations that described the advancement of science and regulations during the past 20-40 years to protect the environment (Chapman 2016;Heinz 2016;LeBlanc 2016;Rattner et al 2016;Schmitt and Mckee 2016;Schultz and Aptula 2016;Shore and Shemesh 2016;Stehle and Schulz 2016;Zitko 2016). These papers addressed some of the most important environmental science research of the last 30-50 years.…”
