TLDR
An approximately molar ratio for these elements in certain human organs following exposure to high levels of inorganic mercury is reported.Abstract:
THE ability of selenium compounds to modify profoundly the toxicity of both organic and inorganic mercury compounds has been demonstrated in experimental animals by Parizek and co-workers1,2. The analytical data of Ganther et al.3 on tuna and of Koeman et al.4 on marine mammals showed that natural levels of mercury and selenium are strongly correlated. Here we report an approximately molar ratio for these elements in certain human organs following exposure to high levels of inorganic mercury.read more

Selenium biochemistry and its role for human health
TL;DR: This review summarizes the most recent findings on the biochemistry of active selenium species in humans, and addresses the latest evidence on the link betweenselenium intake, selenoproteins functionality and beneficial health effects.

Mercury and selenium interaction: A review
TL;DR: The paper also touches on possible mechanisms for the "protective action" of selenium against mercury toxicity and deals briefly with the synergism between the two elements.

Total mercury, methylmercury and selenium in mercury polluted areas in the province Guizhou, China

TL;DR: The general conclusion is that Hg contamination in Wanshan is geographically more widespread, due to deposition and scavenging of Hg from contaminated air and deposition on land, and the population mostly at risk is located in the vicinity of smelting facilities, mining activities and close to the waste disposal sites in the wider area of Wansan.

Mercury-selenium compounds and their toxicological significance: toward a molecular understanding of the mercury-selenium antagonism.
Mohammad A. K. Khan,Feiyue Wang +1 more
TL;DR: This review focuses on the potential Hg‐Se compounds that are responsible for the antagonism at the molecular level, with an emphasis on the bis[methylmercuric]selenide, methylmercury selenocysteinate, selenoprotein P‐bound HgSe clusters, and the biominerals HgSexS1−x.

Selenium: Relation to Decreased Toxicity of Methylmercury Added to Diets Containing Tuna
Howard E. Ganther,C. Goudie,M. L. Sunde,M. J. Kopecky,P. A. Wagner,Sang-Hwan Oh,William G. Hoekstra +6 more
TL;DR: Japanese quail given 20 parts per million of mercury as methylmercury in diets containing 17 percent tuna survived longer than quails given this concentration of methylmerCury in a corn-soya diet.

Mercury-Selenium Correlations in Marine Mammals
TL;DR: The high levels in seal brain suggest that these animals are affected by the toxic action of methylmercury compounds, and the mechanism of binding of mercury to the tissues of seals may be different.

Activation analysis for mercury in biological samples at nanogram level.
L. Kosta,A.R. Byrne +1 more
TL;DR: A new method based on complete ignition of the sample in a silica tube, trapping volatile interfering activities such as bromine or chlorine, and selectively adsorbing mercury on a strip of filter paper which has been previously impregnated with elemental selenium is devised.

Simultaneous neutron-activation determination of selenium and mercury in biological samples by volatilization.
A.R. Byrne,L. Kosta +1 more
TL;DR: The technique originally developed for mercury, based on pyrolysis with filtration of undesirable impurities and selective trapping from the gas phase, is now extended to selenium, and a positive correlation for these elements was found for human tissues.
