Beryllium lung disease. Chronic Beryllium Disease - CBD is a chronic granulomatous lung disease caused by inhaling airborne beryllium after becoming sensitized to beryllium. Some common symptoms of CBD are shortness of breath unexplained coughing fatigue weight loss fever and night sweats. CBD can result from inhalation exposure to beryllium at levels below the current OSHA PEL 02 μgm3.
Most exposures to beryllium that cause disease are related to beryllium processing. The major route of human exposure is through airborne particles of beryllium metal alloys oxides and ceramics. Beryllium particles are inhaled into the lungs and upper respiratory tract.
Hand-to-mouth exposures and skin contact with ultrafine particles can also occur. Although beryllium occurs in. Beryllium oxide BeO also known as beryllia is an inorganic compound with the formula BeO.
This colourless solid is a notable electrical insulator with a higher thermal conductivity than any other non-metal except diamond and exceeds that of most metals. As an amorphous solid beryllium oxide is whiteIts high melting point leads to its use as a refractory material. Among people who work with beryllium exposure can lead to berylliosis also called chronic beryllium disease CBD characterized by decreased lung capacity and effects similar to those caused by the poison gas phosgene.
The oxygen compound beryllium oxide beryllia BeO is a high-temperature refractory material melting point 2530 C 4586 F characterized by an unusual combination. Coal dust is relatively inert and large amounts must be deposited in the lungs before lung disease is clinically detectable. Silica asbestos and beryllium are more reactive than coal dust resulting in fibrotic reactions at lower concentrations.
Most inhaled dust is entrapped in the mucus blanket and rapidly removed from the lung by ciliary movement. However some of the particles become. Our doctors define difficult medical language in easy-to-understand explanations of over 19000 medical terms.

A network meta-analysis of real-world evidence. The most significant reactions of the lung occur in the deepest parts of this organ. Particles that evade elimination in the nose or throat tend to settle in the sacs or close to the end of the airways.
But if the amount of dust is large the macrophage system may fail. Dust particles and dust-containing macrophages collect in the lung tissues causing injury to the lungs. The amount of dust.
The I-ELCAP study included more than 31000 subjects who were at risk for lung cancer because they had a history of cigarette smoking or a history of occupational exposure eg to asbestos beryllium uranium or radon or they had never smoked but had been exposed to second-hand smoke with or without a family history of lung cancer. The study was a systematic case-control observational. Elemental beryllium has a wide variety of applications.
Occupational exposure most often occurs in mining extraction and in the processing of alloy metals containing beryllium. Beryllium can cause sensitization lung and skin disease in a significant percentage of exposed workers. Cadmium is an extremely toxic metal commonly found in industrial workplaces particularly.
