Environmental context Specific inhibitors of biological reactions in the nitrogen cycle can be used to determine origin reactive species; these species potentially degrade water quality or influence climate. However, interfere with methods for analysis stable isotope ratios and concentrations ammonium, nitrite nitrate. The effect this interference on several commonly was investigated. These fin...

In 1932 (1) the author published a method for determining methionine in proteins based on the recovery of methyl iodide. Alcoholic silver nitrate was used as absorbant and the excess of silver nitrate was titrated with thiocyanate after filtering off the silver iodide. This method was quite satisfactory and has been used recently by Barritt (2) for the determination of methionine in wool. Certa...

Study was made on the significance of urinary cadmium concentration as an indicator of internal dose in a general environment polluted by cadmium. As an index of external dose, the mean rice cadmium concentration in each of 23 villages was employed. Morning urine samples were collected from 3,178 inhabitants of 23 cadmium-polluted villages of Kakehashi River basin in Ishikawa Prefecture and 294...

BACKGROUND Environmental exposure to cadmium causes renal dysfunction and bone damage. Cadmium contamination in food is regarded as the main environmental source of non-occupational exposure. The aim of this study was to assess the contribution of dietary cadmium exposure in environmental cadmium exposure and its health risk among adults in Shanghai, China. METHODS A cross-sectional survey ab...

BACKGROUND Cadmium is a widespread environmental pollutant with adverse effects on kidneys and bone, but with insufficiently elucidated public health consequences such as risk of end-stage renal diseases, fractures and cancer. Urinary cadmium is considered a valid biomarker of lifetime kidney accumulation from overall cadmium exposure and thus used in the assessment of cadmium-induced health ef...
