International and domestic approaches to the assessment of cemetery soils in various natural-climatic zones (literature review)

Death is inseparable from the functioning of the biosphere and demonstrates its inherent connection to the presence of humanity on Earth. According to data from the end of 2024, with a total global population of 8.156 billion people, the average daily number of recorded deaths is 170,463, which amounts to 7,103 deaths per hour. An analysis of urbanized areas, which are home to 4.42 billion people, revealed a direct correlation between urban development and the management of burial sites. A historical retrospective shows that urban agglomerations, which have existed for millennia, have traditionally served as sites for interment. Currently, the territories of former burial grounds are used mainly as permanent burial zones, converted into park areas or built-up areas with green spaces. A study of the soil cover in the aforementioned territories revealed specific characteristics due to their original purpose and subsequent land-use transformations. All soils at burial sites are classified as necrosols and are characterized by the following features: turbation of the soil profile, enrichment of deeper soil horizons with phosphorus and carbon, deep mixing of the soil, and the presence of various artifacts and burial remains. In modern soil classification, there is no place for those soils that, after being used for burials, are utilized within built-up areas; they can only be characterized as “technogenic” or “other soils” without indicating the presence of former graves.This article provides a review of foreign and Russian literature devoted to the study of cemetery soils, aiming to classify them according to their degree of impact on the environment and public health. The study did not include soils used for burial sites after the cremation of the bodies of the deceased in a crematorium or for burial sites in family vaults.Contribution: Ushakova O.V. – research concept and design, writing, editing; Rakhmanin Yu.A. – research concept, editing; Evseeva I.S. – research concept and design, collection of material and data processing, writing, editing; Ibragimova S.Sh. – writing, editing.
