[The ecological and epidemiological principles of prevention of ascariasis under the conditions of large-scale solid waste storage].

The paper presents the results of a study of the impact of large-scale solid waste storage on ascariasis morbidity in the population. The use of sewage sediments as an organic soil fertilizer to grow strawberries and table greens is shown to substantially increase the risk of Ascaris infection in the population. Storage of solid domestic garbage on specialized dumping grounds does not lead to mass environmental pollution with geohelminthic eggs.

[Use of geoinformational systems for epidemiological studying malignant laryngeal neoplasms in Krasnoyarsk].

This paper shows it possible to use geoinformational systems for mapping and analyzing medical statistical data on those with malignant laryngeal neoplasms. The fact that the distribution of the patients can be shown on the map of a town in relation to the location of their houses (if they have an address) allows differentiation of the ecological living conditions of these patients, which in turn makes it possible to put not only high morbidity areas on the map of a town, but also to consider the characteristics of the environment in these areas.
