TLDR
The results indicate that consideration of the growth stage of organs and tissues is necessary for understanding the bioaccumulation processes and the toxicological criteria of the metals.Citations

Birds as monitors of pollutants
TL;DR: In this paper, the authors argue that birds may reflect pollutant hazards to humans better than do most invertebrates, since they are high in food chains and have more complex physiology.

Risk, Mercury Levels, and Birds: Relating Adverse Laboratory Effects to Field Biomonitoring
Joanna Burger,Michael Gochfeld +1 more
TL;DR: The levels in tissues that are associated with adverse effects in birds from laboratory studies are reviewed and compared with levels found in wild bird populations in the New York Bight to provide a basis for interpreting values in avian populations.

Geographic trend in mercury measured in common loon feathers and blood
David C. Evers,Joseph D. Kaplan,Michael W. Meyer,Peter S. Reaman,W. Emmett Braselton,Andrew Major,Neil M. Burgess,Anton M. Scheuhammer +7 more
TL;DR: In this paper, the authors examined the relationship between blood and feather Hg concentrations among age and sex classes of the common loon (Gavia immer) in five regions of North America: Alaska, northwestern United States, Upper Great Lakes, New England, and Canadian Maritimes.

Metal-related oxidative stress in birds.
Miia J. Koivula,Tapio Eeva +1 more
TL;DR: Taking birds as model organisms, the mechanisms responsible for antioxidant depletion are summarized and a view of how to detect metal-induced oxidative stress in birds by using different biomarkers is given.
Journal ArticleDOI
Can excrement and feathers of nestling songbirds be used as biomonitors for heavy metal pollution
TL;DR: It is concluded that excrement of great and blue tit nestlings can be used as a biomonitor for heavy metals (lead, cadmium, arsenic, and copper), whereas feathers appear only to be suitable for lead pollution.

Seasonal changes in bone mineral content and alkaline phosphatase activity in the house sparrow (Passer domesticus L.)
TL;DR: The bone zinc content in female sparrows was also at a significantly higher level during laying than at other times of the year, which is assumed to indicate the important role of zinc in processes connected with laying.

Seasonal changes in the copper content of the liver of the Common shrew, Sorex araneus over a two‐year period
TL;DR: Seasonal changes in the liver copper content of the common shrew were measured over two years; in one year the levels remained high until the Spring, but the following winter there was a sharp decrease after December.
