Sources and Transformations of Dissolved Lignin Phenols and Chromophoric Dissolved Organic Matter in Otsuchi Bay, Japan

Dissolved lignin phenols and optical properties of dissolved organic matter (DOM) were measured to investigate the sources and transformations of terrigenous DOM (tDOM) in Otsuchi Bay, Japan. Three rivers discharge into the bay, and relatively high values of syringyl:vanillyl phenols (0.73 ± 0.07) and cinnamyl:vanillyl phenols (0.33 ± 0.10) indicated large contributions of non-woody angiosperm ...

East-West Distribution of Nutrients and Dissolved Inorganic Carbon in the Northern North Pacific in Autumn

We measured nutrient and dissolved inorganic carbon (DIC) concentrations from west to east across the northern North Pacific Ocean from station K2 to Ocean Station Papa during September and October 2005. At 2000 m depth, silicate levels increased and dissolved oxygen levels decreased from west to east. This trend was attributed to seawater in the layer flowing from west to east in the northern ...

Recent trends in bagassosis in Japan.

The only workers presently exposed to bagasse dust in Japan are the employees of sugar refineries and lacquerware factories. A follow up study of six former cases of bagassosis from among the retired employees of a paper board factory, closed since 1973, showed that none of the subjects still had bagassosis. Examinations of 70 employees of a sugar refinery for allergic reactions also showed no ...
