Introduction Mineral dust aerosol plays a critical role in atmospheric chemistry by providing reactive surfaces for trace atmospheric gases. 1-3 Mineral dust particles undergo heterogeneous reactions with nitrogen oxides in the atmosphere to yield adsorbed nitrate, nitrate coatings or deliquesced nitrate layers. 1,4,5 Reactions that can alter NOx (NOx = NO + NO2) concentrations are of great imp...

Disposable nappies (diapers) have been satisfactorily demineralized and used for the collection of excreta from infants and young children during mineral and trace metal balances. It was possible to investigate children of both sexes without immobilization.

Disturbance of mineral status in patients with chronic renal failure (CRF) is one of many complications of this disease. Trace elements analysis in hair is sometime used by clinicians for a diagnosis of mineral status. In the present study concentration of magnesium and other trace elements was determined in serum, erythrocytes, and hair of patients with CRF undergoing hemodialysis (n = 31) and...

Thirty-six daily duplicate diet samples were collected from 12 healthy female Japanese vegans and sodium, potassium, calcium, magnesium, phosphorus, iron, zinc, copper, manganese, iodine, selenium, chromium and molybdenum in the diets were measured to estimate mineral and trace element intake by Japanese vegans. Significantly higher intake of potassium, magnesium, phosphorus, iron, copper, mang...

Globally, coal-fired power plants are the largest industrial source of carbon dioxide (CO2). CO2 emissions from flue gas have potential for direct mineralization with electrostatic precipitator fly ash particles in the field. Demonstration scale accelerated mineral carbonation (AMC) studies were conducted at the Jim Bridger Power Plant, a large coal fired power plant located in Wyoming, USA. AM...

Studies were conducted to determine the effects of increased dietary levels of vitamin and trace mineral mixtures, methionine, meat and bone meal, fish meal, and safflower oil on foot pad dermatitis in dwarf and normal size Single Comb White Leghorn layers. All layers were maintained in individual wire cages throughout a 40-week experiment period. Individual birds were scored for the incidence ...
