Air pollution in Boston bars before and after a smoking ban.

BACKGROUND: We quantified the air quality benefits of a smoke-free workplace law in Boston Massachusetts, U.S.A., by measuring air pollution from secondhand smoke (SHS) in 7 pubs before and after the law, comparing actual ventilation practices to engineering society (ASHRAE) recommendations, and assessing SHS levels using health and comfort indices. METHODS: We performed real-time measurements of respirable particle (RSP) air pollution and particulate polycyclic aromatic hydrocarbons (PPAH), in 7 pubs and outdoors in a model-based design yielding air exchange rates for RSP removal. We also assessed ventilation rates from carbon dioxide concentrations. We compared RSP air pollution to the federal Air Quality Index (AQI) and the National Ambient Air Quality Standard (NAAQS) to assess health risks, and assessed odor and irritation levels using published SHS-RSP thresholds. RESULTS: Pre-smoking-ban RSP levels in 6 pubs (one pub with a non-SHS air quality problem was excluded) averaged 179 microg/m3, 23 times higher than post-ban levels, which averaged 7.7 microg/m3, exceeding the NAAQS for fine particle pollution (PM2.5) by nearly 4-fold. Pre-smoking ban levels of fine particle air pollution in all 7 of the pubs were in the Unhealthy to Hazardous range of the AQI. In the same 6 pubs, pre-ban indoor carcinogenic PPAH averaged 61.7 ng/m3, nearly 10 times higher than post-ban levels of 6.32 ng/m3. Post-ban particulate air pollution levels were in the Good AQI range, except for 1 venue with a defective gas-fired deep-fat fryer, while post-ban carcinogen levels in all 7 pubs were lower than outdoors. CONCLUSION: During smoking, although pub ventilation rates per occupant were within ASHRAE design parameters for the control of carbon dioxide levels for the number of occupants present, they failed to control SHS carcinogens or RSP. Nonsmokers' SHS odor and irritation sensory thresholds were massively exceeded. Post-ban air pollution measurements showed 90% to 95% reductions in PPAH and RSP respectively, differing little from outdoor concentrations. Ventilation failed to control SHS, leading to increased risk of the diseases of air pollution for nonsmoking workers and patrons. Boston's smoking ban eliminated this risk.

An alumni-based evaluation of graduate training in health communication: results of a survey on careers, salaries, competencies, and emerging trends.

Published information about career options and the core competencies necessary for health communication professionals (HCPs) is limited. Although the number of graduate programs in health communication continues to grow, no formal assessment of the success of this type of training has been conducted. The current study presents the results of an evaluation of the Master's Program in Health Communication offered collaboratively by Emerson College and the Tufts University School of Medicine. The program was one of the first of its kind and has graduated more health communication students than any other in the United States. To conduct the assessment of the program, the two schools collaborated on the development of an on-line survey for the alumni. Of the 131 graduates eligible to participate, 106 completed the survey. The survey yielded detailed information on the following: (1) career options for individuals with master's degrees in health communication; (2) value of graduate coursework for developing competencies in health communication; (3) salary expectations for individuals with graduate degrees in health communication; and (4) emerging trends in the field. These findings have important implications for the development of new programs and the refinement of existing ones in health communication.

Assessment of sources of second-hand smoke exposure in a putatively unexposed population.

The authors sought to determine levels of urinary cotinine and its association with collateral exposure to second-hand smoke in public health workers. Urinary cotinine was measured twice at 1-wk intervals in 28 public health workers or their spouses. Information on sources of second-hand smoke exposure and a dietary history were obtained from each participant. Geometric mean and median cotinine levels were 2.74 and 2.33 ng/mL, respectively. Only 6 instances of second-hand smoke exposure were reported from a combined 204 days of potential exposure, and these did not correspond to higher cotinine values. There was no association between consumption of foods containing nicotine and log-transformed urine cotinine levels (p = .80). The authors' analysis indicates dietary sources of nicotine are not important, even for persons with very low urinary cotinine levels. Further study is needed to determine sources of variation in urinary cotinine among largely unexposed populations.

Leave no one behind: improving health and risk communication through attention to literacy.

Twice in recent times, the federal government mailed critical health-related information to every household in the United States. The mailings, the 1988 brochure Understanding AIDS and the 2001 postcard A Message to Americans, were designed to provide the general public with important information about needed action. This paper compares the development process undertaken for each mailing. The authors assess content and format in light of communication principles and the functional literacy skills of average adults. The authors, noting that the reading grade level of the postcard exceeds the reading ability of the average adult, recommend that plain language guidelines be combined with health and risk communication principles in all future efforts to alert the public.
