In a proof-of-concept experiment, researchers from Johns Hopkins Medicine say they have successfully used microscopic man-made particles to predict the severity of patients’ chronic obstructive pulmonary disease (COPD) by measuring how quickly the particles move through mucus samples. The technique, say the researchers, could eventually help doctors deliver more effective treatments sooner.
The National Institute for Occupational Safety and Health (NIOSH) has begun offering a series of free, confidential health screenings to coal miners as part of the Coal Workers’ Health Surveillance Program (CWHSP). The screenings are intended to provide early detection of coal workers’ pneumoconiosis (CWP), also known as black lung, a serious but preventable occupational lung disease in coal miners caused by breathing respirable coal mine dust.
Lung function is a predictor of mortality in the general population, as well as in patients with lung disease, even in those who have never smoked. Maintaining lung function is an important goal in the prevention of chronic respiratory diseases and a major public health objective; yet, smoking cessation remains the main target to reduce the burden of these diseases.
Most people know that smoking cigarettes can lead to severe lung damage, including chronic obstructive pulmonary disease, or COPD. What they may not realize is that COPD can occur from exposure to hazardous substances at work as well. At the National Institute for Occupational Safety and Health (NIOSH), investigators are studying the causes and how to prevent COPD.
Lung disease from work-related exposure to coal mine dust can damage different parts of the lungs, including the small airways. When these airways, which resemble twigs branching off the trunk of a tree, are damaged, breathing can become significantly difficult.
Asbestos is a long, thin, fibrous mineral made of up of microscopic crystals. There are six different types that are split up into two different groups: serpentine or amphibole. Serpentine asbestos is classified by its layered structure and curly fibers. One particular type of serpentine asbestos – chrysotile – is most commonly found in building materials throughout the United States.
Mercury and Lead Pollution from Mining-
More than two million people globally are affected by mining and ore processing. These mining sites provide various minerals and metals to produce variety of products and minerals. The most hazardous chemicals that are found near these sites are lead, chromium, asbestos, arsenic, cadmium and mercury.
Declaring the risks of contracting permanent or deadly lung disease “serious,” the CDC recently finalized a warning to employers and workers in the coffee, popcorn and other food and beverage businesses: Beware of diacetyl.
National Institute for Occupational Safety and Health (NIOSH) investigators have found that that the highest rates of airway obstruction were in jobs related to installation, maintenance, and repair; construction; and oil and gas extraction.
