Project description:Background People who smoke with serious mental illness carry disproportionate costs from smoking, including poor health and premature death from tobacco-related illnesses. Hospitals in New Zealand are ostensibly smoke-free; however, some mental health wards have resisted implementing this policy. Aim This study explored smoking in acute metal health wards using data emerging from a large sociological study on modern acute psychiatric units. Methods Eighty-five in-depth, semi-structured interviews were conducted with staff and service users from four units. Data were analysed using a social constructionist problem representation approach. Results Although high-level smoke-free policies were mandatory, most participants disregarded these policies and smoking occurred in internal courtyards. Staff reasoned that acute admissions were not the time to quit smoking, citing the sceptres of distress and possibly violence; further, they found smoking challenging to combat. Inconsistent enforcement of smoke-free policies was common and problematic. Many service users also rejected smoke-free policies; they considered smoking facilitated social connections, alleviated boredom, and helped them feel calm in a distressing environment – some started or increased smoking following admission. A minority viewed smoking as a problem; a fire hazard, or pollutant. No one mentioned its health risks. Conclusion Psychiatric wards remain overlooked corners where hospital smoke-free policies are inconsistently applied or ignored. Well-meaning staff hold strong but anachronistic views about smoking. To neglect smoking cessation support for people with serious mental illness is discriminatory and perpetuates health and socioeconomic inequities. However, blanket applications of generic policy are unlikely to succeed. Solutions may include myth-busting education for service users and staff, local champions, and strong managerial support and leadership, with additional resourcing during transition phases. Smoke-free policies need consistent application with non-judgemental NRT and, potentially, other treatments. Smoking cessation would be supported by better designed facilities with more options for alleviating boredom, expressing autonomy, facilitating social connections, and reducing distress.

Project description:Identifying communities vulnerable to adverse health effects from exposure to wildfire smoke may help prepare responses, increase the resilience to smoke and improve public health outcomes during smoke days. We developed a Community Health-Vulnerability Index (CHVI) based on factors known to increase the risks of health effects from air pollution and wildfire smoke exposures. These factors included county prevalence rates for asthma in children and adults, chronic obstructive pulmonary disease, hypertension, diabetes, obesity, percent of population 65 years of age and older, and indicators of socioeconomic status including poverty, education, income and unemployment. Using air quality simulated for the period between 2008 and 2012 over the continental U.S. we also characterized the population size at risk with respect to the level and duration of exposure to fire-originated fine particulate matter (fire-PM2.5) and CHVI. We estimate that 10% of the population (30.5 million) lived in the areas where the contribution of fire-PM2.5 to annual average ambient PM2.5 was high (>1.5 ?g/m3) and that 10.3 million individuals experienced unhealthy air quality levels for more than 10 days due to smoke. Using CHVI we identified the most vulnerable counties and determined that these communities experience more smoke exposures in comparison to less vulnerable communities.

Project description:Fine particulate matter (PM2.5) from U.S. anthropogenic sources is decreasing. However, previous studies have predicted that PM2.5 emissions from wildfires will increase in the midcentury to next century, potentially offsetting improvements gained by continued reductions in anthropogenic emissions. Therefore, some regions could experience worse air quality, degraded visibility, and increases in population-level exposure. We use global climate model simulations to estimate the impacts of changing fire emissions on air quality, visibility, and premature deaths in the middle and late 21st century. We find that PM2.5 concentrations will decrease overall in the contiguous United States (CONUS) due to decreasing anthropogenic emissions (total PM2.5 decreases by 3% in Representative Concentration Pathway [RCP] 8.5 and 34% in RCP4.5 by 2100), but increasing fire-related PM2.5 (fire-related PM2.5 increases by 55% in RCP4.5 and 190% in RCP8.5 by 2100) offsets these benefits and causes increases in total PM2.5 in some regions. We predict that the average visibility will improve across the CONUS, but fire-related PM2.5 will reduce visibility on the worst days in western and southeastern U.S. regions. We estimate that the number of deaths attributable to total PM2.5 will decrease in both the RCP4.5 and RCP8.5 scenarios (from 6% to 4-5%), but the absolute number of premature deaths attributable to fire-related PM2.5 will double compared to early 21st century. We provide the first estimates of future smoke health and visibility impacts using a prognostic land-fire model. Our results suggest the importance of using realistic fire emissions in future air quality projections.

Project description:Wildfires are a natural component in many terrestrial ecosystems and often play a crucial role in maintaining biodiversity, particularly in the fire-prone regions of Australia. A prime example of plants that are able to persist in these regions is the genus Banksia. Most Banksia species that occur in fire-prone regions produce woody seed pods (follicles), which open during or soon after fire to release seeds into the post-fire environment. For population persistence, many Banksia species depend on recruitment from these canopy-stored seeds. Therefore, it is critical that their seeds are protected from heat and rapid oxidation during fire. Here, we show how different species of Banksia protect their seeds inside follicles while simultaneously opening up when experiencing fire. The ability of the follicles to protect seeds from heat is demonstrated by intense 180 s experimental burns, in which the maximum temperatures near the seeds ranged from ∼75°C for B. serrata to ∼90°C for B. prionotes and ∼95°C for B. candolleana, contrasting with the mean surface temperature of ∼450°C. Many seeds of native Australian plants, including those of Banksia, are able to survive these temperatures. Structural analysis of individual follicles from these three Banksia species demonstrates that all of them rely on a multicomponent system, consisting of two valves, a porous separator and a thin layer of air surrounding the seeds. The particular geometric arrangement of these components determines the rate of heat transfer more than the tissue properties alone, revealing that a strong embedment into the central rachis can compensate for thin follicle valves. Furthermore, we highlight the role of the separator as an important thermal insulator. Our study suggests that the genus Banksia employs a variety of combinations in terms of follicle size, valve thickness, composition and geometric arrangement to effectively protect canopy-stored seeds during fire.

Project description:Landfilling should be the last option in an integrated Municipal Solid Waste (MSW) management approach. In the European Union (EU), the policy framework to protect the environment and the public health against the impact of health hazards related to urban solid waste management has been consistently implemented in recent decades. A growing interest in the negative impact of fires in waste landfills on the environment and people's health was reported in some European countries. In Italy, an increasing occurrence of arsons in MSW and landfills has been reported in recent years. During the summer of 2012, a multi-site arson occurred in the Palermo Municipal solid waste landfill of Bellolampo (western Sicily), giving rise to an environmental emergency of public health concern. Local health authorities reacted by creating an inter-institutional multidisciplinary task force with the aim to implement measures to prevent and control the risk of exposure by delimiting a protection area to be taken under strict monitoring. Environmental and epidemiological investigations were put in place by air, soil, and farm product sampling. A syndromic surveillance of the exposed population was conducted as well. The air monitoring stations system in place detected an increase in the concentrations of dioxins and dioxin-like substances with the PM10 highest emission pick documented within the first 24 h and estimated at about 60 ?g/m3. Levels of heavy metals above the limits permitted by law were detected in the top- and sub-soil samples collected within the two landfill sampling sites and also in other nearby sites. Non-conforming concentration values of dioxins and dioxin-like substances were detected in samples taken from farms, milk, and water. The health syndromic surveillance did not document any daily increase in the notification of emergency admissions related to acute respiratory diseases or any other health effect potentially related to the waste arson, but these findings were limited by the non-systematic collection of data. The experience reported in the present case report, as declined within the European Union policy framework and in the view of environmental justice, documented the need to structure a permanent collaboration between the different institutional actors involved in environmental and public health protection activities in order to develop specific protocols to manage events related to the occurrence of waste-related environmental emergencies or disasters.

Project description:BackgroundTribal sovereignty exempts tribal casinos from statewide smoking bans.PurposeTo conduct a tribally-led assessment to identify the characteristics of casino patrons at Lake of the Torches Resort Casino in Lac du Flambeau WI and their preferences for a smoke-free casino.MethodsA survey was administered from April to August 2011 to a stratified random sample of 957 members of the casino players club to assess their preferences for a smoke-free casino. These members were categorized into three groups: those who reported being likely to (1) visit more; (2) visit less; or (3) visit the same if the casino prohibited smoking. They were characterized by age, education, sex, race/ethnicity, annual income, players club level, and reasons for visiting the casino. Statistical analyses were conducted on weighted data in October to December 2011. Weighted logistic regression was calculated to control for potential confounding of patron characteristics.ResultsOf the 957 surveyed patrons, 520 (54%) patrons were likely to visit more; 173 (18%) patrons to visit less; and 264 (28%) patrons were indifferent to the smoke-free status. Patrons more likely to prefer a smoke-free casino tended to be white, elderly, middle class and above, and visit the casino restaurants. Patrons within the lower tiers of the players club, almost half of the players club members, also showed a higher preference for a smoke-free casino.ConclusionsThis tribal casino would likely realize increased patronage associated with smoke-free status while also contributing to improved health for casino workers and patrons.

Project description:Many of the photovoltaic (PV) systems on buildings are of sufficiently high voltages, with potential to cause or promote fires. However, research about photovoltaic fires is insufficient. This paper focuses on the flammability and fire hazards of photovoltaic modules. Bench-scale experiments based on polycrystalline silicon PV modules have been conducted using a cone calorimeter. Several parameters including ignition time (tig), mass loss, heat release rate (HRR), carbon monoxide (CO) and carbon dioxide (CO₂) concentration, were investigated. The fire behaviours, fire hazards and toxicity of gases released by PV modules are assessed based on experimental results. The results show that PV modules under tests are inflammable with the critical heat flux of 26 kW/m². This work will lead to better understanding on photovoltaic fires and how to help authorities determine the appropriate fire safety provisions for controlling photovoltaic fires.

Project description:BackgroundSince the 2016 presidential election, reports have suggested that President Trump's rhetoric and his administration's proposed policies could be exacerbating barriers to accessing health care for undocumented as well as lawfully present immigrants and their families in the United States. However, very little empirical work has analyzed this possibility or detailed how these reports and rhetoric have altered the health seeking behavior of mixed immigration status families.MethodsUsing a series of focus groups throughout Texas in both English and Spanish, this qualitative study analyzes changes to health access for immigrants. We consulted Community Health Workers to better understand the barriers encountered by their otherwise hard-to-reach undocumented clients and their families as they interface with the health system, revealing key insights about the changing nature of barriers to access under the Trump administration.ResultsWe identify four key themes about the changing nature of immigrant health access in the United States: growing fear of interacting with health and social services; that social networks are paradoxically limiting health access in the current political climate; that the administration's rhetoric and proposed policies are impeding health seeking behavior; and that children are encountering new barriers to social program participation.ConclusionsThe Trump administration, its proposed immigration policies, and his rhetoric are posing new and significant barriers to health access for immigrants and their families.

Project description:BackgroundExposure to biomass smoke is a major cause of morbidity and mortality in Africa. Commercial food vendors in Nigeria and elsewhere in Africa are commonly exposed to biomass smoke from open fire cooking both at work and home. Little is known about the knowledge, attitudes and beliefs of food vendors about the health hazards of biomass smoke exposure in Nigeria.MethodsWe did a descriptive cross sectional survey of the knowledge, attitudes and beliefs of commercial food vendors in the cities of Benin and Calabar in Nigeria. We recruited respondents using a multi-stage approach. Structured interviewer-administered questionnaires were used for data collection.ResultsWe recruited 308 participants (164, 53.2% female). The majority 185(60.2%) were married and had post-primary education 206(67.4%). The average monthly income was <30,000 Naira (US$150). Most 198(64.4%) were not aware that biomass smoke exposure is harmful to human health. About three-quarters (221; 71.8%) were unconcerned as to the effect of exposure to fumes from biomass fuels on their health. Less than half of respondents (110, 41.6%) believed biomass smoke was harmful to health. Male gender, being single, having post-primary education and preferring electricity or gas fuels were associated with good knowledge of the adverse health effects of biomass smoke exposure whilst female gender and having good knowledge of the adverse health effects of biomass smoke were associated with positive attitudes towards preventing exposure.ConclusionCommercial food vendors in our study had limited knowledge about the adverse health effects of biomass smoke exposure and negative attitudes towards preventing these adverse health effects. We suggest an educational intervention is needed to improve this knowledge.
