ENVIRONMENTAL RISK ASSESSMENT METHODS BASED ON HETEROGENEOUS DATA

The methods of environmental risk assessment , based on the analysis of pollutants measurement results in various media, expert assessments and situational models were developed. Heterogeneous data is merged in a unified normalized scale, taking into account reliability characteristics and each factor participation degree. Method of hierarchies analysis is applied for complex environmental risk assessment. Implementation of comprehensive evaluation in GIS technology allows to combine disparate data in a multi-layered project , to connect data processing modules for the purpose of critical loads' visual mapping and identifying areas, that are most sensitive to pollutants occurrence.
