[Motor transport emission, ambient air quality, and the Moscow population's health].
As of 2006, the city's motor transport fleet amounted to as many as 3 million units that annually consume about 5 million tons of petrol. The use rate of all kinds of vehicles has increased, resulting in the growth of the proportion of ambient air pollutants discharged by motor transport, which surpasses the increase of the absolute size of the fleet. The contribution of traveling sources to ambient air pollution is growing steadily and it has been recently about 90% (1 million tons). ⋯ There is stabilization in morbidity due to respiratory diseases in all population groups. The prevalence of chronic respiratory diseases in children is on the decrease, the increase rate was 1.4% versus 33.5% in the preceding period. Assessment of carcinogenic risk showed that ambient air pollution and drinking water contamination had a negative impact on the Moscow population.

[Assessment of real risk of urban chemical exposure to the population's health].
Improving the chemoanalytical quality control of the urban environment requires transition from the assessment considering only certain things determined by target analyses to the comprehensive assessment based on monitoring with the identification of the maximally complete spectra of substances contained in the environmental objects and coming from the sources of pollution, by using the appropriate algorithm; identification, quantifying a spectrum of pollutants as completely as possible; selection of the leading indices, by evaluating the detected composition of pollutions from the degree of their hygienic significance, by taking into account a set of criteria (detection rate, concentrations, group affiliation, specificity for a nearby source of pollution in the check of drinking water, a capacity for transformation, possible formation of more toxic transformation products); and monitoring through target tests by the chosen leading indices.

Review[Current problems in the assessment of health risks and damages from the influence of environmental factors].
In the past decade, a great number of risk assessment projects have been implemented; experience in using the risk-assessing methodology in sociohygienic monitoring, in the hygienic evaluation of a possible impact of new or rebuilt plants on human health, and in the estimation of natural and cost damages from the influence of environmental factors has been gained. Along with the legal aspects of using the risk-assessing methodology, there is a diversity of urgent and unsolved problems: a discrepancy between the hygienic standards and the risk-assessing criteria established in our country, recommended by international organizations, or used in the leading countries of the world; evaluation of exposures; availability of data on exposures in both individual regions and Russia as whole; development of methods for the assessment of damages and for the comparative assessment of risks, including such indices and their value terms as lost life years and life years with consideration of the severity of abnormalities.
