Dear colleagues, On behalf of my co-authors, I am pleased to share our new publication "Temporal Baseline of Essential and Non‑essential Elements Recorded in Baleen of Western Arctic Bowhead Whale (Balaena mysticetus)" published in Bulletin of Environmental Contamination and Toxicology. This paper is Open Access and available for free download here: https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Feproofing.... ABSTRACT: This study established the frst baseline of changing elemental concentrations in bowhead whale baleen over time (1958– 1999). From previously published stable isotope data, year, season (summer or winter), and location (Beaufort or Bering/ Chukchi seas) were attributed to each sample. Thirteen elements (Al, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, V, Zn) in baleen from nine subsistence-harvested bowhead whales (n=138) were detected. Al, Cu, and Fe were the highest concentrations while Cd and V were among the lowest. Our data supports absorption as the main route of exposure to environmental elements rather than biomagnifcation due to bowhead whales’ low trophic position. A linear mixed-efects model confrmed most elements’ concentrations increased with time, while location and sex were insignifcant explanatory factors. These temporal fuctuations were most likely a product of environmental changes due to a warming climate and human activities. Regards, Amy C. Hirons Amy C.
