Using the results of environmental monitoring for economic calculations on the example of adjusting the cost of land plots using the indicative method

Abstract

The purpose of the work is to compare the ranges of the cadastral value of land plots with the environmental situation in these territories. The issue is considered on the example of the impact of polycyclic aromatic hydrocarbons (PAH) on industrial-urbanized territories adjacent to two enterprises, one of which is located in Moscow (a waste incineration plant), the other in the Moscow region (a plant producing metal products, Podolsk). The assessment of the toxic impact of biologically available PAHs on these territories was carried out using a new indicative method developed by the author. A feature of this method is taking into account not only the concentration of pollutants in the objects under study, but also the physicochemical and toxicological properties of each compound. The results of the study, presented in cartographic form, were compared for the first time with maps of the cadastral value of land plots located in the studied territories. The comparison showed that the price of land plots in most cases is not proportional to the level of toxic effects of polyaromatic hydrocarbons, that is, the environmental component was not taken into account when forming their cost. However, the obvious connection between chemical pollution of territories and economic damage (including damage to the health of the population living in polluted territories) gives reason to propose a way to correct the cadastral value by dividing it by a correction factor that reflects the degree of contamination of the territory with compounds of the PAH group and represents the equivalent of the concentration of one of the most toxic polycyclic aromatic hydrocarbons, benzo(a)pyrene, the impact of which on humans and the environment corresponds to a similar total impact of PAHs contained in the soil of a particular territory.
