“…Indigenous People and subsistence hunters in Alaska also have a long history of harvesting and consuming marine resources, including seabirds and their eggs (Burger et al 2007 ; Naves 2009 ). Mercury accumulation in seabirds from the Aleutian Islands has also been well documented (Burger et al 2007 , 2008 , 2009 ; Burger and Gochfeld 2009 ; Savoy et al 2017 ). According to Burger et al ( 2007 ), 90% of households from an Aleutian village consumed birds to some degree each year.…”

An important provision of the Minamata Convention on Mercury is to monitor and evaluate the effectiveness of the adopted measures and its implementation. Here, we describe for the first time currently available biotic mercury (Hg) data on a global scale to improve the understanding of global efforts to reduce the impact of Hg pollution on people and the environment. Data from the peer-reviewed literature were compiled in the Global Biotic Mercury Synthesis (GBMS) database (>550,000 data points). These data provide a foundation for establishing a biomonitoring framework needed to track Hg concentrations in biota globally. We describe Hg exposure in the taxa identified by the Minamata Convention: fish, sea turtles, birds, and marine mammals. Based on the GBMS database, Hg concentrations are presented at relevant geographic scales for continents and oceanic basins. We identify some effective regional templates for monitoring methylmercury (MeHg) availability in the environment, but overall illustrate that there is a general lack of regional biomonitoring initiatives around the world, especially in Africa, Australia, Indo-Pacific, Middle East, and South Atlantic and Pacific Oceans. Temporal trend data for Hg in biota are generally limited. Ecologically sensitive sites (where biota have above average MeHg tissue concentrations) have been identified throughout the world. Efforts to model and quantify ecosystem sensitivity locally, regionally, and globally could help establish effective and efficient biomonitoring programs. We present a framework for a global Hg biomonitoring network that includes a three-step continental and oceanic approach to integrate existing biomonitoring efforts and prioritize filling regional data gaps linked with key Hg sources. We describe a standardized approach that builds on an evidence-based evaluation to assess the Minamata Convention’s progress to reduce the impact of global Hg pollution on people and the environment.

“…Eider prey primarily includes a diversity of benthic invertebrates (e.g., urchins, mussels, and gastropods) as well as pelagic macroinvertebrates to a lesser extent (e.g., amphipods; Sénéchal et al 2011;Kristjánsson et al 2013;Waltho and Coulson 2015). The abundance and distribution of these prey groups vary spatio-temporally and correlate with both predator Hg concentrations and phenological shifts in primary production (Mouritsen et al 2005;Barber et al 2015;Fort et al 2016;Savoy et al 2017). Thus, examining δ 15 N, δ 13 C and Hg niche dynamics of a costal, primarily benthic foraging species provides an avenue to investigate the future impact of prey shifts and the resulting influence on Hg exposure (Sénéchal et al 2011), as well as relative differences in ice algae and phytoplankton-based food webs in relation to sea-ice cover (Søreide et al 2012;Kohlbach et al 2016).…”
