Stable carbon isotopes in human tissues

Nature, 1978
ON studying the distribution of 14C from nuclear weapon tests in a wide range of human tissues, it was observed that significant modification of 14C/12C isotopic ratio had occurred, largely as a function of variable carbon renewal rates1,2. As a parallel exercise, 13C/12C isotope ratios have been assayed, 13C and 12C being the nonradioactive isotopes ...

Stable Carbon and Nitrogen Isotopic

Aquatic Geochemistry, 2004
The perennially ice-covered lakes in the McMurdo Dry Valleys, Antarctica, are part of the coldest and driest ecosystem on earth. To understand lacustrine carbon and nitrogen cycling in this end-member ecosystem, and to define paleolimnological proxies for ice-covered lakes, we measured the stable carbon and nitrogen isotopic composition of particulate ...

Mercury and Stable Isotopes of Carbon and Nitrogen in Mink

Environmental Toxicology and Chemistry, 2007
Abstract Total Hg concentrations and values of stable isotopes (δ15N, δ13C) in tissues of mink (Mustela vison) captured in Rhode Island (USA) during winters of 1999 to 2004 were statistically distinct based on location. Mink captured in salt marsh environments (salt marsh group mink [SMGM]) had significantly lower mean Hg concentrations ...
