Barium sulfate aspiration.
A woman was evaluated for dyspnea after she inhaled barium sulfate during an upper gastrointestinal barium study that was administered by means of a percutaneous endo scopic gastrostomy tube. A plain radiograph of the chest revealed alveolar barium sulfate depositions (arrows) in the middle lobe of the right lung and in the lower lobes and the posterior aspects of the upper lobes of both lungs ...
متن کاملThe interaction of EDTA with barium sulfate.
Ethylenediaminetetraacetic acid (EDTA) is a known complexing agent that interacts with a host of cations. In this paper, various techniques are used to elucidate the mechanism of interaction between EDTA and barium sulfate surfaces. It is shown that complexation with metal ions is not sufficient to explain the inhibition of barite crystallization but that other processes such as chemisorption m...
متن کاملFlotation of Barium Sulfate Contaminants Soils
Flotation is, doubtless, the most important process among the various techniques used for the treatment of ore. This generalpurpose technique allows the treatment of several complex ores (lead zinc, copper zinc), sulphides (copper, lead, and zinc), oxides (hematite, quartz), oxidized minerals (malachite, cerusite) and even non-metal ores (fluorite, phosphate, coal). Due to the flotation, it is ...
متن کاملBarium sulfate bronchography. Report of a complication.
Alveolarization of the barium sulfate and subsequent retention of barium sulfate for years was demonstrated in three patients in whom dilute suspension of barium sulfate in water was used for bronchography. Pathologic examination in one patient showed barium sulfate within macrophages in the alveolar spaces and walls and in the perivascular and peribronchial interstitium. Since the residual bar...
