Data Sources for an Environmental Quality Index: Availability, Quality, and Utility

Fuzzy Wastewater Quality Index Determination for Environmental Quality Assessment under Uncertain and Vagueness Conditions

Utilization of water in different parts of industrial life cycles brings a huge concern on environmental water and wastewater pollutions. In this research, environmental quality assessment of wastewater is studied using fuzzy logic. Fuzzy appliance is due to existance of statistical considerations (including standard deviations), various uncertainties, non-linearity and complexity of functions....

Measuring environmental quality: an index of pollution

This paper develops an index of pollution based on the epidemiological dose-response function associated with each pollutant, and the welfare losses due to exposure to pollution. The probability of damage is translated into welfare losses, which provides the common metric required for aggregation. Isopollution surfaces may then be used to compare environmental quality over time and space. An Ai...

Construction of an environmental quality index for public health research

BACKGROUND A more comprehensive estimate of environmental quality would improve our understanding of the relationship between environmental conditions and human health. An environmental quality index (EQI) for all counties in the U.S. was developed. METHODS The EQI was developed in four parts: domain identification; data source acquisition; variable construction; and data reduction. Five envi...

Improving integration quality for heterogeneous data sources

This work considers a problem of integrating heterogeneous semi–structured data sources with the purpose of estimating integration quality (IQ). During the integration of such data sources the IQ estimation plays an important role, because correspondences and dependencies within and across the sources are not completely known, the schema or semantics might be missing, which leads to results wit...
