The existing methodology for human health risk assessment allows one to appreciably study cause-and-effect relationships between environmental factors and human health. Risk management is a logic continuation of the assessment of human health risk and it is aimed at substantiating the choice of decisions that are best in a specific situation to eliminate or minimize it, to make follow-up monitoring of exposures and a risk, to evaluate the efficiency of health-improving measures and to correct the latter. Risk management involves technical, technological, organizational, social, legal, economic, normative, political, and other decisions made on the conclusions and estimates obtained when characterizing the risk.
