The Continuing Persistence of Silicosis

Silica is the most abundant compound in the earth's crust. Inhalation of crystalline silica is the only cause of silicosis, a preventable but incurable type of lung fibrosis. Inhalation has also been associated with lung cancer, tuberculosis, COPD and other conditions.  Read More >

Low-dose CT Scans and Lung Cancer Screening in the Occupational Setting

Lung cancer mortality is high and better survival prognosis for early stage cases makes early detection an appealing public health strategy. For years studies have been conducted to find an effective screening method; the NLST is the first randomized trial to show a significant reduction in mortality from lung cancer with low-dose CT screening.  Read More >

Helical CT Scans and Lung Cancer Screening

New research has revealed that a relatively new form of screening using helical computerized tomography (CT) may result in fewer lung cancer deaths. This finding is of interest to the occupational safety and health community to potentially improve cancer screening among workers with increased risk for lung cancer because of past occupational exposures. Read More >

Warning: Surgeon General Finds that Cigarette Smoking Is Even More Dangerous to Your Health

Yesterday, the Surgeon General issued the 30th Surgeon General's Report on the dangers of smoking tobacco. Tobacco use remains the leading cause of preventable death in the United States, and is responsible for 443,000 deaths each year. Tobacco use can increase risk of illness for those exposed to carcinogens in the workplace and second-hand smoke can place non-smoking workers at risk for smoking-related diseases. Read More >

N95 Respirators and Surgical Masks

The emergence of H1N1 has created considerable interest about the use of surgical masks and respirators as infection control measures. Given the recent issuance of revised CDC infection control guidance for healthcare personnel that include recommendations for use of N95 respirators, NIOSH has posted a new blog that examines the scientific principles behind the design and performance of these devices. Read More >

Respiratory Protection for Terrorist Threats and Other Emergencies

This September 11th marks eight years since the devastating attacks on the World Trade Center. Since then, NIOSH has developed a systematic approach to identify the hazards that responders would face, assess the capabilities of existing respiratory protection equipment to provide protection against viable threats using benchmark testing, and set certification standards that stretch the capabilities of the protective technologies to enhance the protection offered to responders during CBRN events. Read More >

Secondhand Smoke and Casino Dealers

Simply working in a casino does not mean dealers must gamble with their health. Results of new research conducted by NIOSH on secondhand smoke—the exposure of non-smokers to tobacco smoke—confirm that dealers at the casinos investigated were exposed to secondhand smoke. Read More >

Diacetyl and Food Flavorings

Commercial flavorings used in the food service industry are often complex mixtures of flavoring chemicals, many of which are volatile, meaning that they evaporate into the air from their liquid or solid form. Diacetyl is a prominent chemical ingredient in butter flavorings and is a component of the vapors coming from these and other flavorings. Inhalation of butter flavoring chemical mixtures, including diacetyl, has been associated with severe obstructive lung disease popularly know as "popcorn lung." Read More >
