Baltimore Hookah Bars Contain Elevated Levels of Carbon Monoxide and Air Nicotine

30.05.2014

Smoking waterpipes, or hookahs, creates hazardous concentrations of indoor air pollution and poses increased risk from diminished air quality for both employees and patrons of waterpipe bars, according to a new study from the Institute for Global Tobacco Control at the Johns Hopkins Bloomberg School of Public Health.

In an analysis of air quality in seven Baltimore waterpipe bars, researchers found that airborne particulate matter and carbon monoxide exceeded concentrations previously measured in public places that allowed cigarette smoking and that air nicotine was markedly higher than in smoke-free establishments. The study appeared in the April 16, 2014 online edition of the Journal of Exposure Science and Environmental Epidemiology.

Tobacco-related research and tobacco control efforts in the United States have generally focused on cigarettes, but other forms of tobacco products and tobacco use are common in many countries, including the U.S. Waterpipe cafes–also known as hookah bars–have grown in popularity in the U.S. and worldwide, particularly among young adults. For their study, researchers surveyed seven waterpipe cafes in Baltimore, Maryland, from December 2011 to August 2012. They measured carbon monoxide levels, airborne nicotine content and respirable particulate matter with a mean particle diameter of less than 2.5 microns (PM2.5). A micron is approximately 1/30th the width of a strand of human hair.

“There is a mistaken notion that tobacco smoking in a water pipe is safer than cigarettes,” said Patrick Breysse, PhD, professor in the Department of Environmental Health Sciences and the study’s senior author.  “Our results suggest that this is not the case. Our study found that waterpipe smoking creates higher levels of indoor air pollution than cigarette smoking, placing patrons and employees at increased health risk from secondhand smoke exposure.”

Indoor airborne concentrations of PM2.5 and carbon monoxide were markedly elevated in Baltimore waterpipe cafes, confirming that waterpipe smoking severely affects indoor air quality. Air nicotine concentrations, although not as high as in hospitality venues that allow cigarette smoking, were also elevated and markedly higher than levels previously found in smoke-free bars and restaurants. Some of these measurements consistently exceeded air quality standards set by the U.S. Environmental Protection Agency and the World Health Organization.

“Public education efforts need to be developed to educate users about the hazards of water pipe use and tobacco control policies need to be strengthened to include water pipes,” said Christine Torrey, BA, senior research specialist in the Department of Environmental Health Sciences and the study’s lead author.

Im Focus: Worldwide Success of Tyrolean Wastewater Treatment Technology

A biological and energy-efficient process, developed and patented by the University of Innsbruck, converts nitrogen compounds in wastewater treatment facilities into harmless atmospheric nitrogen gas. This innovative technology is now being refined and marketed jointly with the United States’ DC Water and Sewer Authority (DC Water). The largest DEMON®-system in a wastewater treatment plant is currently being built in Washington, DC.

The DEMON®-system was developed and patented by the University of Innsbruck 11 years ago. Today this successful technology has been implemented in about 70...

Im Focus: Computational high-throughput screening finds hard magnets containing less rare earth elements

Permanent magnets are very important for technologies of the future like electromobility and renewable energy, and rare earth elements (REE) are necessary for their manufacture. The Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, has now succeeded in identifying promising approaches and materials for new permanent magnets through use of an in-house simulation process based on high-throughput screening (HTS). The team was able to improve magnetic properties this way and at the same time replaced REE with elements that are less expensive and readily available. The results were published in the online technical journal “Scientific Reports”.

The starting point for IWM researchers Wolfgang Körner, Georg Krugel, and Christian Elsässer was a neodymium-iron-nitrogen compound based on a type of...

Im Focus: Atomic precision: technologies for the next-but-one generation of microchips

In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.

In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...
