“…In a study of 158 women, 25.29 μg/day of dietary heavy metal intake leads to several osteoporosis cases and fracturing. Dainowski et al [51] studied the total mercury (THg) concentration on muscle, kidney, and liver of red foxes in Western Alaska. It was seen that total mercury concentration in hair is correlated with muscle, kidney, and liver.…”

Mercury was the name of the Roman messenger of god who can move really fast. It is also called as quicksilver due to its fast movement and silvery tinge. Liquid metal state mercury (Hg) has little to no solubility and is not poisonous. But the liquid mercury can vaporize, and gaseous mercury becomes poisonous due to its nature of being absorbed into the blood. Mercury in +2 state is more poisonous due to high solubility. Mercury is the only metal that exists in liquid state at normal temperature and pressure. Mercury poisoning occurs by exposure to mercury, i.e., acute and chronic exposures. Symptoms of mercury poisoning depend on the type, dose, method, and duration of exposure. Mercury poisoning effects on the human body are not limited to reddishness of hands and feet; renal failures; cardiovascular, liver, brain, and hormonal issues; and intestinal ulceration. The present chapter describes the mercury sources, types of exposures, types of poisoning, treatments, and preventive measures of mercury poisoning.

“…There are, however, limitations with interpreting these trophic level interactions when they are determined only from stable isotope data; for example, the age and health status of the animal [ 42 , 43 ]. The average life span of a red fox is five years in the wild; the animal is sexually mature at around 10 months [ 5 ]. The red fox may move north into the Arctic fox range following development of road systems [ 44 ].…”

“…Additionally, by including students and citizens in the monitoring plan, it becomes more holistic by measuring impacts on the various “capitals” that may be impacted ( Figure 5 ). Red foxes, river otters, mink, and even dogs have been used as bioindicator species to monitor variation in mercury concentrations both within a species and between different species living in a local geophysical region or ecosystem [ 5 , 21 , 34 , 51 ]. Foxes can provide information on Hg biomagnification patterns and changes in exposure.…”

“…Today, pollution also enters the river by global transport form other regions, especially Asia, with its recent activity in energy and economic development [ 2 , 3 ]. Industrially created persistent organic chemicals and metals are being reported, both in the watershed and its derived food services, such as salmon [ 1 , 4 , 5 ]. The Yukon River is not only important to local and regional ecosystem service issues but also has global economic and industrial applications.…”

Resilience and Adaptation: Yukon River Watershed Contaminant Risk Indicators

River watersheds are among the most complex terrestrial features in Alaska, performing valuable ecosystem functions and providing services for human society. Rivers are vital to both estuarine and aquatic biota and play important roles in biogeochemical cycles and physical processes. The functions of watersheds have been used as vulnerability indicators for ecosystem and socioeconomic resilience. Despite a long history of human activity, the Yukon River has not received the holistic and interdisciplinary attention given to the other great American river systems. By using hypothesis-based monitoring of key watershed functions, we can gain insight to regime-shifting stresses such as fire, toxins, and invasive species development. Coupling adaptive risk management practices involving stakeholders with place-based education, especially contaminants and nutrition related, can maintain resilience within communities. The Yukon watershed provides a broadscale opportunity for communities to monitor the environment, manage resources, and contribute to stewardship policy formation. Monitoring keystone species and community activities, such as citizen science, are critical first steps to following changes to resiliency throughout the Yukon watershed. Creating a policy environment that encourages local experimentation and innovation contributes to resilience maintenance during development-imposed stress.

Anthropogenic pollutants disrupt global biodiversity, and terrestrial sentinels of pollution can provide a warning system for ecosystem-wide contamination. This study sought to assess whether raccoons (Procyon lotor) are sentinels of local exposure to trace element contaminants at a coal fly ash site and whether exposure resulted in health impairment or changes in the intestinal helminth communities. We compared trace element accumulation and the impact on health responses and intestinal helminth communities of raccoons inhabiting contaminated and reference sites of the U.S. Department of Energy’s Savannah River Site (South Carolina, USA). Data on morphometry, hematology, histopathology, helminth community and abundance, and liver trace element burdens were collected from 15 raccoons captured adjacent to a coal fly ash basin and 11 raccoons from a comparable uncontaminated site nearby. Of eight trace elements analyzed, Cu, As, Se, and Pb were elevated in raccoons from the contaminated site. Raccoons from the contaminated site harbored higher helminth abundance than animals from the reference site and that abundance was positively associated with increased Cu concentrations. While we found changes in hematology associated with increased Se exposure, we did not find physiological or histological changes associated with higher levels of contaminants. Our results suggest that raccoons and their intestinal helminths act as sentinels of trace elements in the environment associated with coal fly ash contamination.Electronic supplementary materialThe online version of this article (doi:10.1007/s00244-016-0340-2) contains supplementary material, which is available to authorized users.
