AMBIENT MEASUREMENTS OF AIR TOXIC POLLUTANTS AT RESURRECTION CATHOLIC SCHOOL IN BOYLE HEIGHTS Journal Article BACKGROUND AND OBJECTIVES Boyle Heights is a neighborhood located on the eastern bank of the Los Angeles River, east of downtown Los Angeles. The extensive East Los Angeles Interchange (the busiest freeway interchange in the world) passes through Boyle Heights, allowing access to the Golden State (I- 5), Hollywood (U.S. Route 101), Pomona (SR 60), San Bernardino (I-10), Santa Ana (…
Comparison of the aerosol produced by electronic cigarettes with conventional cigarettes and the shisha Journal Article In previous studies of the smoke from regular cigarettes and water pipes, we measured aerosol particle sizes in three streams; S1, inhaled by the smoker, S2, released by the device itself and
Electronic cigarette aerosol particle size distribution measurements Journal Article The particle size distribution of aerosols produced by electronic cigarettes was measured in an undiluted state by a spectral transmission procedure and after high dilution with an electrical mobility analyzer.
Electronic Cigarettes and Secondhand Aerosol Web Page Electronic (e-) Cigarettes and Secondhand Aerosol “If you are around somebody who is using e-cigarettes, you are breathing an aerosol of exhaled nicotine, ultra-fine particles, volatile organic compounds, and other toxins,” Dr. Stanton Glantz, Director for the Center for Tobacco Control Research and Education at the University of California, San Francisco.
Environmental Health Criteria Monographs (EHCs)- Formaldehyde (EHC 89, 1989) Web Page 1.8 Effects on Man Formaldehyde has a pungent odour detectable at low concentrations, and its vapour and solutions are known skin and eye irritants in human beings. The common effects of formaldehyde exposure are various symptoms caused by irritation of the mucosa in the eyes and upper airways. In the non-industrial indoor environment, sensory reactions are typical effects, but there are large indiv…
Government study finds toxic Roundup herbicide in 75 percent of air, rain samples Web Page Tuesday, March 11, 2014 by: Jonathan Benson, staff writer (NaturalNews) You might not want to hold your tongue out to catch that enticing drop the next time it rains
Human Breath Emissions of VOCs Journal Article ABSTRACT The medical community has long recognized that humans exhale volatile organic compounds (VOCs). Several studies have quantified emissions of VOCs from human breath, with values ranging widely due to variation between and within individuals. The authors have measured human breath concentrations of isoprene and pentane.

Influential parameters on particle concentration and size distribution in the mainstream of e-cigarettes Journal Article Electronic cigarette-generated mainstream aerosols were characterized in terms of particle number concentrations and size distributions through a Condensation Particle Counter and a Fast Mobility Particle Sizer spectrometer, respectively. A thermodilution system was also used to properly sample and dilute the mainstream aerosol.
Involuntary smoking in the restaurant workplace: A review of employee exposure and health effects Journal Article Objective.\\  To determine the relative exposure to environmental tobacco smoke for bar and restaurant employees compared with office employees and with nonsmokers exposed in the home (part 1) and to determine whether this exposure is contributing to an elevated lung cancer risk in these employees (part 2).
Legislating abjection? Secondhand smoke, tobacco control policy and the public's health Journal Article Since the mid-1990s the position that “no amount of secondhand smoke is safe” has achieved hegemonic status in the field of public health. This has bolstered efforts in the tobacco control community to advocate for smoke-free legislation and a variety of countries around the world have implemented indoor smoking bans, with many others presently following suit. Increasingly, tobacco contro…
Levels of selected carcinogens and toxicants in vapour from electronic cigarettes Journal Article Significance Electronic cigarettes, also known as e-cigarettes, are devices designed to imitate regular cigarettes and deliver nicotine via inhalation without combusting tobacco. They are purported to deliver nicotine without other toxicants and to be a safer alternative to regular cigarettes. However, little toxicity testing has been performed to evaluate the chemical nature of vapour generat…
Scientists Find the Same Ecig “Toxins” In Regular Human Breath Blog Post All over the country, lawmakers are arguing that vaping should be banned in public areas because they fear it will put people at risk through secondhand exposure. Most recently, Los Angeles joined the campaign to outlaw public vaping, claiming that ecig vapor contains dangerous toxins like lead, nickel, nicotine, and chromium. After doing a little research, we found scientific evidence to refute lawmaker claims. It tur…
Sources of Propylene Glycol and Glycol Ethers in Air at Home Journal Article Propylene glycol and glycol ether (PGE) in indoor air have recently been associated with asthma and allergies as well as sensitization in children. In this follow-up report, sources of the PGEs in indoor air were investigated in 390 homes of pre-school age children in Sweden.
Third-hand smoking: indoor measurements of concentration and sizes of cigarette smoke particles after resuspension Journal Letter In a previous study1 of ‘secondhand’ cigarette smoke, we showed that 75% of the particles added to indoor air were of ultrafine sizes and had a half-life in air of 18 minutes at 25°C. These particles after their deposition on household surfaces could be later put back in suspension and constitute a toxic ‘thirdhand’
