Abstract

Sulfur isotopic composition of biological samples has been determined to investigate the behaviors of sulfur in the environment. δ34S values of fishes range from +17 to 20 o/oo and show that sulfur comes from the sea-water salfate whose δ S value is 20 o/oo. In contrast, δ34S values of plants whose sulfur is derived from water soluble sulfate in soil and sulfur dioxide in the atmosphere are scattered in the wide range from -7 to +14 o/oo. It became obvious that plants growing in the north hemisphere tend to show a less δ34S value than those of south hemisphere. Meat sulfur coming from soil through the foodchain shows almost the same tendency as plant sulfur. These results are reflected to the δ34S values for nail sulfur of humanbeing that stands on the top of the foodchain.
