the environmental problems, in different dimensions, are resulted from the lack of environmental considerations and criteria in locating new cities. the main purpose of this article is to compare different criteria based on library studies and expert opinions and determining suitable criteria in order to evaluate the environmental potential to establish new cities to achieve urban permanent dev...

The current situation of world’s environmental issues, indicates that not only the man-made environmental damages have not been diminished, but also has given rise to more acute issues such as water and soil pollution, biodiversity loss, ozone depletion, greenhouse phenomena, etc. One of the most prominent effects of urban development on environmental problems caused by solid waste generated in...

The SAB should be aware that the process of risk assessment within the federal agencies has at least a 30-year history (the NRC “Red Book” was published in 1983) and has undergone much review. While US EPA is one of the leading federal agencies in the evolution of toxicological risk assessments, the appropriate venue for making significant changes to the risk assessment process should include t...

Environmental aspects plays a central role in environmental management system (EMS) because it is the basis for the identification of an organization’s environmental targets. The existing methods for the assessment of environmental aspects are grouped into three categories: risk assessment-based (RA-based), LCA-based and criterion-based methods. To combine the benefits of these three categories...

Trichloroethylene (TCE) was found as a contaminant in the well supplying water to an aquatic testing laboratory. The groundwater was routinely screened by a commercial laboratory for volatile and semivolatile compounds, metals, herbicides, pesticides, and polychlorinated biphenyls using U.S. Environmental Protection Agency methods. Although TCE was the only reportable peak on the gas chromatogr...

In this paper, some aspects of the psychophysical background of environmental noise assessment are touched. Psychophysical methods useful for the measurement of environmental noise are mentioned. The simulation of the loudness perception for normal hearing and hearing impaired persons is illustrated. Moreover, the influence of the meaning of sound as well as of additional modalities on noise as...
