Short-term increases in particulate air pollution are linked with increased daily mortality and morbidity. Socioeconomic status (SES) is a determinant of overall health. We investigated whether social class is an effect modifier of the PM(10) (particulate matter with diameter <10 micron)-daily mortality association, and possible mechanisms for this effect modification. ⋯ The results confirm previous suggestions of a stronger effect of particulate air pollution among people in low social class. Given the uneven geographical distributions of social deprivation and traffic emissions in Rome, the most likely explanation is a differential burden of chronic health conditions conferring a greater susceptibility to less advantaged people.

Comparative Study
In vivo protective performance of N95 respirator and surgical facemask.
The SARS outbreak in 2003 has spawned a major controversy concerning protective performance facemasks for healthcare workers. This study reports a study on in-vivo protective performance of surgical masks and N95 respirators. ⋯ Surgical masks can provide in-vivo filtration protection of 95% filtration efficiency. N95 respirators provide higher in-vivo filtration efficiency of 97% with significant reduction of air permeability and water vapor permeability. Compared to normal surgical masks/respirators, the nano-masks can provide additional protective functions in stopping capillary diffusion and antibacterial activities.

Assessments of the impact of occupational amputations with outcomes of pain, disfigurement, and often an inability to return to the same job, are limited. The present study examines and quantifies the rates, risk factors, and costs of occupational amputations in the workplace in the State of Kentucky. ⋯ Workplace amputations remain a significant workplace concern and represent a particular hazard for those in the mining and manufacturing industries. Future research should examine causes of the weekend effect to develop human resource and safety interventions for risk reduction.

The North American Guidelines for Children's Agricultural Tasks (NAGCAT) are a safety resource created to assist parents in selecting safe work for their children 7-16 years of age. Since their release in 1999, a growing body of scientific evidence has accumulated regarding NAGCAT. The purpose of this project was to assess the current scientific and programmatic evidence regarding the efficacy and utilization of the NAGCAT resource in order to determine the priorities for the next 5 years. ⋯ This assessment and priority identification process was successful in outlining the next steps for the NAGCAT resource. As we move toward 2010, those involved in pediatric agricultural injury prevention will have a blueprint to ensure that NAGCAT are an effective and widely used resource for preventing work-related injuries.

U.S. Army Chemical Corps veterans handled and sprayed herbicides in Vietnam resulting in exposure to Agent Orange and its contaminant 2,3,7, 8-tetrachlorodibenzo-p-dioxin (TCDD or dioxin). This study examined the long-term health effects associated with herbicide exposure among these Vietnam veterans. ⋯ Vietnam veterans who were occupationally exposed to herbicide experienced a higher risk of several chronic medical conditions relative to other non-Vietnam veterans. A potential selection bias is of concern. However, there were relatively high participation rates in both the Vietnam and non-Vietnam veteran groups, and the prevalence rates of some of these medical conditions among non-Vietnam veterans were comparable to general populations. Therefore, self-selection factors are considered unlikely to have biased the study results.
