The study aims to explore the interrelation of perceived air pollution and objective air pollution in the context of various subjective wellbeing (SWB) measures. An original survey data is used, and matched with exogenous levels of PM2.5 pollution in one of Warsaw’s city districts, to capture the short-term exposure and immediate SWB assessments. The log-linear analysis and the Two-Stage Conditional Maximum Likelihood estimations have found both the perceived and objective air pollution to have a negative effect on reported life satisfaction. Using the instrumental variable approach, the hypothesis of endogeneity of perceived pollution to SWB is rejected.
The accident at the Chornobyl Nuclear Power Plant was one of the largest in human history. It is often referred to as a global event because its effects were felt not only by Ukrainians but also by the populations of Belarus, Russia, Central Europe, the Balkans and the Scandinavian Peninsula. 2022 marked the 36th anniversary of this terrible occurrence, when the history of Ukraine in the late twentieth century was divided into two parts: before the tragedy of 26 April 1986, and after it.
Today, it is important for Ukrainian society not only to recognise the significance of the catastrophe and remember its victims but also to find ways to overcome its grave consequences. This requires comprehensive research useful for developing new approaches to minimising the environmental and socio-demographic problems caused by the Chornobyl tragedy. Thus, this research has practical scientific, humanitarian and socio-political significance. The novelty of the obtained results lies in the study’s critical rethinking of the achievements of predecessors and its analysis of historical sources concerning the environmental and socio-demographic consequences of the accident at the Chornobyl Nuclear Power Plant as they manifested from 1986 to 2022.
The methodological basis of the work is empirical cognition. The use of logical-analytical methods of grouping and typology allows us to classify homogeneous events and coherently present the material of the article. The study additionally uses comparative judgment, historical-statistical and problem-chronological methods. The principles of objectivity and impartiality also play an important role in the work.
The purpose of the study is to investigate the consequences of the Chornobyl Nuclear Power Plant accident on the environmental and socio-demographic aspects of the population of Ukraine from 1986 to 2022 based on the identified set of sources. From a historical perspective, the level of pollution in the territories of Ukraine is traced, the demographic situation is monitored, and parallels are drawn between the Chornobyl disaster and the increase in incurable diseases and mortality.
In conclusion, the authors note that although 36 years have passed, the echo of this catastrophe remains tangible for the population of Ukraine. Several issues still must be solved. The first is the return to life, namely, the safe living and management of areas that have been exposed to radiation contamination, as well as the continuation of work aimed at restoring agricultural soils. Second, purposeful work must be conducted by the state to minimise social and demographic problems resulting from the Chornobyl catastrophe. In our opinion, the government should increase expenditures aimed at providing quality medical services to the population of Ukraine, as well as conduct constant monitoring of the health of those people who are at high risk in order to better detect diseases in their early stages.
These groups of people include liquidators of the consequences of the accident and migrants. Such measures can stabilise the demographic situation by increasing birth rates and reducing mortality, as well as improve the health and living standards of the population of Ukraine.
It has been substantiated that the increase in the concentration of heavy metals in the environment has especially aggravated in the conditions of military operations on the territory of Ukraine. The use of woody plants for the purposes of phytoremediation is one of the most effective options for optimising the state of the environment in urban ecosystems, regardless of the nature and source of contamination by metallic elements, which is of significant relevance in the conditions of post-war environmental restoration of Ukraine. The purpose of the study is to explore the peculiarities of some heavy metals accumulation by the assimilation apparatuses of the black locust (Robinia pseudoacacia L.) plants growing in the recreational areas of the city of Dnipro in order to further optimise tree plantings with the aim of improving the environment. The content of heavy metal elements (Cu, Zn, Pb, and Cd) in the biomass of the Robinia pseudoacacia L. leaves and in the soils of Dnipro recreation areas has been determined. The intensity of the accumulation of heavy metals in the phytomass of the Robinia pseudoacacia L. represents the following sequence Zn > Cu > Pb > Cd, which demonstrates a more intense absorption and accumulation in the phytomass of the leafy fraction of Zn and Cu in the phytomass of the deciduous fraction, and less significant of Pb and Cd. With the help of geo-information systems, cartographic material has been developed. It demonstrates the concentration gradient of Pb, Cu, Cd, and Zn in the assimilation organs of the black locust plants in the city of Dnipro recreational areas. Based on the cartographic analysis, it has been proved that the general condition of the soils in the recreation areas of Dnipro is characterised by significant disproportions in the level of pollution. The maps show the existing potential of the accumulative capacity of Robinia pseudoacacia L. to deposit Pb, Cu, Cd, and Zn, which allows for additional city functional zoning by considering phytoremediation functions of the existing and planned green spaces.
