Flight crew have higher rates of specific cancers than the general population, according to a study in the open access journal Environmental Health involving 5,366 US flight attendants. Some of this increased cancer incidence may be related to the number of years flight attendants spend in their jobs (job tenure).
US flight attendants have a higher prevalence of several forms of cancer, including breast cancer, uterine cancer, gastrointestinal cancer, thyroid cancer, and cervical cancer, when compared with the general public, according to new research from Harvard T.H. Chan School of Public Health.
A new aerosol chemistry study presented at the 1st Scientific Summit -- Tobacco Harm Reduction: Novel products, Research & Policy, has revealed toxicant levels in myblu pod-system e-cigarette aerosols are up to 99 percent lower than in cigarette smoke.
Researchers at Portland State University have developed methods for measuring levels of free-base nicotine in electronic cigarette (e-cigarette) liquids and vapor, the levels of which are associated with harshness upon inhalation of e-cigarette vapors and tobacco smoke.
This question isn't only for people who've smoked a lot. Seven factors, including two new ones, can predict whether you have a high risk of developing lung cancer.
With summer coming, it's only a matter of time before the smells and tastes of barbecued foods dominate the neighborhood. But there's a downside to grilling that can literally get under your skin. In a study appearing in Environmental Science & Technology, scientists report that skin is a more important pathway for uptake of cancer-causing compounds produced during barbecuing than inhalation. They also found that clothing cannot fully protect individuals from this exposure.
Portland State University researchers who published an article three years ago in the New England Journal of Medicine about the presence of previously undiscovered forms of formaldehyde in e-cigarette vapor revisited their research and found that formaldehyde risks were even higher than they originally thought.
Smoking tobacco from a waterpipe, also known as a hookah, accounted for over half of the tobacco smoke volume consumed by young adult hookah and cigarette smokers in the US, a new University of Pittsburgh School of Medicine analysis discovered. In the US, hookah smoking rates are increasing and cigarette smoking rates are decreasing, especially among young adults.
Researchers measuring air in an unoccupied, nonsmoking classroom found that almost 30 percent of the tiny particles in it were associated with residue of so-called thirdhand smoke, a finding that reveals a whole new route by which people can be exposed to smoke from tobacco products.
Despite decades of indoor smoking bans and restrictions, new research from Drexel University suggests the toxins we've been trying to keep out are still finding their way into the air inside. Findings by a group of environmental engineers show that third-hand smoke, the chemical residue from cigarette smoke that attaches to anything and anyone in the vicinity of a smoke cloud, can make its way into the air and circulate through buildings where no one is smoking.
