Popis: Objectives. From the point of view of the technogenic impact, due to human activity, the soil is the most affected, compared to other components of nature. The danger of soil pollution is determined by the level of its possible negative effect on the contact media (water, air), food and, directly or indirectly, on the health of the population, as well as on the biological activity of the soil and self-cleaning processes. The aim of the study was the hygienic evaluation of soil quality indices in the localities of the Republic of Moldova and estimation of the effectiveness of the surveillance system of the studied field. Materials and methods. As object of the study in the current paper served the qualitative and quantitative data of the hygienic surveillance of soil quality, in the localities of the Republic of Moldova, for the period 2014-2019. The current study applied hygienic, sanitary-chemical, analytical and statistical investigation methods (calculation of relative and average indicators, determination of the trend and approximate confidence value used). Results and discussions. The share of non-compliancy of soil quality to chemical, microbiological and helminth parameters, for the evaluated period, was on average, 4,11%, 23,4% and 9,32%, respectively. For the period of 2014-2019, there is an increase in non-compliant soil samples to microbiological parameters, on average annually by 3,7% (R2 = 0.80). The percentage of soil samples that did not correspond to current hygienic regulations, regarding the presence of helminth eggs, shows a decrease for the estimated period, on average annually by 2,46% (R2 = 0.89). The percentage of soil samples, which did not correspond to the hygienic regulations in force regarding the presence of helminth eggs, shows a decrease for the estimated period, on average annually by 2.46% (R2 = 0.89). It should be noted that the number of soil samples investigated for chemical, microbiological parameters and the presence of helminth eggs, in the estimated period, decreased significantly. Conclusion. Hygienic surveillance of the soil in localities, plays an important role in ensuring the sanitary and epidemiological well-being of the population.
