Hispanic residents suffer disproportionately from exposure to toxic pollution hazards, but little is known about why some Hispanic residents live in high-risk neighbourhoods while others are protected from similar risks. This study uses comparative interview-based methods to further understanding of Hispanic people’s residential decision-making and their associated exposures to hazardous air pollutants (HAPs) in the Miami Metropolitan Statistical Area (Florida), which is home to one of the most diverse Hispanic populations in the U.S. We use 22 in-depth interviews conducted with Hispanic householders living at high and low risk to HAPs, selected from a larger representative phone survey of 650 local residents. For Hispanic households at high risk, economic constraints, family ties, desiring a central location, a sense of community, and comfort in a shared culture contributed to their residences in high risk locations. In contrast, protective factors for Hispanic households living at low risk included the desire to live in an ethnically diverse setting, the ease of finding service work, and preferring environmental amenities and exclusivity. Findings demonstrate that there are considerable differences in factors shaping residential decision-making of low- and high-risk Hispanic residents, but that all were influenced by economic, socio-cultural, and environmental considerations to varying degrees. 相似文献

This work is intended to show the characterization of three effluents (X, Y, and Z) derived from laboratory analyses conducted in the quality control department of a beneficiated bentonite products factory in order to present alternatives for their treatment and final disposal according to Brazil's National Solid Waste Policy (Política Nacional de Resíduos Sólidos – PNRS, Law 12,305/2010, Brazil). Analyses to identify the characteristics of the effluents revealed that the pH, salinity, electroconductivity, and total dissolved solids were in agreement with the organic and mineral nature of the effluent constituents: solvent, clay minerals, water, and activating agent. To assess reuse proposals, the effluents were subjected to the following tests: (a) swelling characteristic with effluent X, (b) petrochemical characterization of Y, and (c) swelling characteristic using commercial solvent and activated clay produced with effluent Z. Preliminary results indicate that each of these effluents can be reused variously in the laboratory, as a fuel, or in the original analysis/process. 相似文献

The aim of this study was to validate the visual estimation method for aggregated plate waste of main dish at Portuguese primary school canteens. For this purpose plate waste at school lunch was measured for 505 individual servings, using weighing individual servings and plate waste and visual estimation method by a 6-point scale, as developed by Comstock et al. (1981). A high variability of initial serving weights was found with serving sizes ranging from 88.9 to 283.3 g and with a coefficient of variation ranging from 5.5% to 24.7%. Mean plate waste was 27.5% according to the weighing method. There was a significant bias in the conversion of the visual waste estimations to actual waste, being overestimated by an average of 8.0 g (ranging from ?12.9 g to 41.4 g). According to Bland and Altman plot, the mean difference between methods was of 8.0 g and the amplitude interval was 102.6 g. The study showed that the visual estimation method is not as accurate as the weighing method in assessing nonselective aggregated plate waste at primary school canteens. Our findings are thus very important on considering plate waste assessment, since the wide variation on initial servings introduces a relevant bias when considering standard portions or a random sample of initial servings. Although, greater convenience, time-saving and the possibility to monitor plate waste of large groups, make the visual estimation method an important method to assess plate waste at school canteens, these results highlighted the need of portions standardization and control of initial servings to allow for its use. 相似文献

The introduction of genetically modified plants into the environment has been marked by different positions, either in favor of or against their release. However, the problem goes well beyond such contradictory positions; it is necessary to take into account the legislation, ethics, biosafety, and the environment in the considerations related to the release of genetically modified organisms (GMOs). To this end, the Brazilian Committee of Biosafety (CTNBio), a consultative and deliberative multidisciplinary collegiate, provides technical and advisory support to the Brazilian Federal Government. This committee consists of scientists and non-scientists who participate in evaluating the dossiers of companies that are requesting approval by the Brazilian Government; consequently, the aim of this study was to investigate whether commercial approvals of GMOs were associated with the profile of the CTNBio members. Research was based on the minutes taken at CTNBio meetings carried out from 2006 up to 2009, considering law 11.105/2005 and the Constitution of 1988 as legal frameworks, to determine the number of voters in favor of or against releasing genetically modified Bt-maize, Bt-cotton, and herbicide resistant soybeans to be used in Brazilian agriculture. Via the internet, we had access to the curriculum vitae of the CTNBio members through the Plataforma Lattes database of the National Council for Scientific and Technological Development (CNPq), where we found their area of expertise. CTNBio members were divided into expert-for, expert-against, non-expert-for, and non-expert-against. Results showed that CTNBio decisions could be based on technical criteria as well as on the policy of the institution that expert-members were representing. 相似文献
