The slope of the simple linear regression between log 10 transformed mercury (Hg)
concentration and stable nitrogen isotope values (δ 15 N), hereafter called trophic magnification …

Total mercury (THg), methylmercury (MeHg) and 22 other trace elements were measured in
ice algae, three species of zooplankton, mixed zooplankton samples, Arctic cod (…

With increasing pressure placed on natural systems by growing human populations, both
scientists and resource managers need a better understanding of the relationships between …

Threshold concentrations associated with adverse effects of dietary exposure to methylmercury
(MeHg) were derived from published results of laboratory studies on a variety of fish …

Fish mercury (Hg) concentrations have been measured over the last 30–40 years in all
regions of Canada as part of various monitoring and research programs. Despite this large …

Seasonal variation in mercury (Hg) concentrations and food web structure was assessed for
eastern Lake Ontario. Hg concentrations, measured in 6 species of invertebrates and 8 …

Rubidium (Rb), a rarely studied alkali metal, may be an essential ultra-trace element for
humans and other organisms. However, very little information exists in regard to the …

The trophic roles of key Ponto-Caspian invaders (quagga mussels Dreissena bugensis,
amphipods Echinogammarus ischnus and round goby Apollonia melanostomus) within the …

Ecosystems often experience multiple environmental stressors simultaneously that can
differ widely in their pathways and strengths of impact. Differences in the relative impact of …

The distribution of total mercury (THg) within common deciduous trees and the applicability
of tree cores as biomonitors of historical environmental THg trends were assessed for both …
