This article examines results from in-depth interviews conducted with parents of children with asthma living in an urban environment. We examine themes from the in-depth interviews related to participants' perceptions of the influence of their physical environment on their mental and physical health, and the actions that they take in an effort to protect their health within this context. The findings from this study suggest several implications for understanding the interface between the physical environment of urban communities and residents' health, as well as for the policy and practice of risk assessment strategies.  相似文献

According to the 20/20/20 strategy by European Union for green energy by 2020 priority should be given to the Renewable Energy Sources. The energy generated from the wind has proven to be of interest for several reasons—wind is available, it is a cheap, and virtually inexhaustible source of energy. In this relation in the last years, many wind power stations were built all around the country. They are being located in proximity of populated areas. Their work besides the generation of electricity is connected to emission of physical factors in the environment that could be essential for human health. In order to avoid overexposure to electromagnetic fields, noise, and vibration to the general public minimal safety distance is being determined theoretically for ‘worst case” conditions basing on the technical characteristics of the generators. After the mounting of installations, measurements have to be performed to determine whether the national and European safety limits for the factors of environment are being kept. The paper presents results of measurement of electromagnetic fields, additionally noise and vibration around one of the biggest wind power parks in Bulgaria. The measurements were made in the close proximity of the generators both for the personnel working conditions and for the population in the closest living areas.  相似文献

This paper introduces a new methodology for measuring and modeling manufacturers’ environmental performance and the managerial and technological practices that affect it. Facility level licensing data are used to develop indicators based on sector-specific criteria but capable of being analyzed across sectors, at various levels of aggregation. This addresses the problem that environmental performance and determinants tend to be highly context-specific, while modeling and policy interests are often more general. Using Integrated Pollution Control (IPC) information generated EU-wide, this approach should be capable of cross-country extension. The methodology is tested on a sample of Irish facilities in three sectors during 1996–2004. Preliminary results show its usefulness in exploring the determinants of environmental performance at the sector and cross sector levels. Word count = 10,049.  相似文献

Cost estimates are frequently developed to evaluate hazardous‐waste‐site cleanup options in support of a site investigation, remedy selection decision, or assessment of environmental liabilities. The accuracy of the cost estimate depends largely on the quality of the information available at the time it is prepared. This article presents a practical guide to developing a cleanup cost estimate. It includes information on how to document assumptions, use the latest technical resources, and perform basic adjustments to account for uncertainty and the time value of money. The content is based upon a recent guidance document issued by the U.S. Environmental Protection Agency and U.S. Army Corps of Engineers entitled A Guide to Developing and Documenting Cost Estimates during the Feasibility Study (USEPA, 2000). © 2001 John Wiley & Sons, Inc.  相似文献

Intrauterine fetal brain death is a rare cause of a fixed fetal heart rate pattern. Seven cases have been previously reported in the literature, but only two of them were diagnosed prenatally and all the newborns died soon after delivery. Two additional cases of antepartum diagnosis of intrauterine fetal brain death, managed expectantly, are reported. We had the unique opportunity to document progressive sonographic cerebral changes during the follow-up period, following the neurological event, while the fetus continued life and growth in utero. The cardiographic and sonographic findings suggesting intrauterine fetal brain death were a prolonged fixed fetal heart rate, even following a vibroacoustic and contraction stress test; an atonic fetus without breathing and body movement; and the appearance of hydramnios and the development of ventriculomegaly.  相似文献
