This article considers methodological approaches to a comprehensive assessment of the impact of environmental factors on the health of a megacity population for the purpose of making targeted management decisions. We propose a methodology for constructing a Risk Assessment Map (RAM) in tabular and graphical (using GIS technologies) variants and consider using data from the ecological and hygienic monitoring. The stage of risk mapping consists of systematization and generalization of data on emissions of leading industrial enterprises, power engineering and motor transport objects, taking into account the main meteorological conditions and objective characteristics of the impact of pollution of environmental objects on the health status of the population in various areas of the megacity. By the method of expert assessments, we suggest assigning ranks for each criterion of the risk factor being evaluated, followed by the derivation of the general rank of the risk probability.
