“…To calculate the risk, it was proposed to use the maximum permissible concentration of individual nitrogen compounds, and the threshold value (sensitivity coefficient k n =11.3 mgN/dm 3 ) for the sum of nitrogen concentrations. This indicator is the property of the implementation of the provisions of the nitrate directive in different countries, including Ukraine [39]. A close linear relationship between the values of R` and k n was established for individual rivers by year (Fig.…”

A method has been developed for quantitative and qualitative assessment of the risk of surface water pollution by nitrogen compounds based on the use of the indicator of the total content of inorganic nitrogen forms in water (Ninorg), that is, This indicator is considered as the sensitivity coefficient kn. The choice of the indicator is dictated by the need to protect waters from pollution caused by nitrogen compounds during their flow from agricultural sources (Directive 91/676 /EU). The experience of developed countries has shown that nitrogen compounds deteriorate the quality of water and prevent the achievement of a "good ecological state" of water bodies. For territories with developed agriculture, it is important to establish environmental risks of damage depending on the degree of nitrogen pollution. Quantitative assessments of environmental risk are provided on the basis of a probabilistic approach. The risk was calculated as the product of the probability of a hazardous event occurring multiplied by the consequences of this event. The consequences of river pollution with nitrogen compounds were assessed as the ratio of the total concentration of nitrogen compounds (sensitivity index kn) to its threshold value (50 mg/dm3 or 11.3 mgN/dm3). In order to develop a scale for qualitative and quantitative risk assessment, relationships were established between the sensitivity indicators kн and the risk indicators R' for individual rivers, and for the study area as a whole, by means of spatio-temporal generalization. The probabilistic characteristics of possible environmental damage were determined on the basis of the obtained regression equations of the form R'=f(kn) and the statistical law of distribution of the risk value R'. The developed method will make it possible to determine the rank of the risk zone and the probability of getting into it, depending on the given sensitivity indicator kn

There were analyzed the effect of increased concentration of biogenic elements, as well as increased temperature on the frequency and magnitude of cyanobacteria reproduction. The goal was to identify the main causes of poor water quality in surface water bodies of Ukraine compared to European countries, as well as the impact of municipal wastewater entering water bodies on the quality of water in them. It is shown that pollution with biogenic elements (compounds of nitrogen and phosphorus) is one of the main reasons for unsatisfactory water quality in water bodies. This, in turn, is the cause of a number of such problems as the change in biological diversity and productivity of water bodies due to the eutrophication of freshwater and marine ecosystems, and the spread of diseases associated with unsatisfactory drinking water quality. One of the main sources of biogenic elements entering surface water bodies is municipal wastewater. Long-term observations of the composition of wastewater from municipal sewage systems indicate that the concentration of biogenic elements in them can be different. It largely depends on the sources of the effluents. In the total amount of nitrogen and phosphorus compounds entering the wastewater, a significant place is occupied by the economic activity of the inhabitants of the residential areas. Experience shows that, regardless of the level of water supply, the total mass of biogens entering the sewage systems from one inhabitant over a certain period of time is constant. However, taking into account the fact that the water availability for residents is different, the concentration of biogens in wastewater will also be different due to different dilutions. The calculation shows that for the entire possible range of water consumption levels (from 100 to 285 l/day per inhabitant according to the standards), the concentration of biogenic elements in wastewater can be: total nitrogen – from 38.6 to 110 mg/l; ammonium nitrogen – from 36.1 to 102.8 mg/l; nitrites – from 2.35 to 6.74 mg/l; nitrates – from 43.27 to 123.67 mg/l; total phosphorus – from 6.31 to 18 mg/l; phosphates – from 15.49 to 44.17 mg/l; organic phosphorus – from 1.26 to 3.60 mg/l.

The Revolution of Dignity and instrumentalisation of LGBT rights: How did attitudes towards LGBT people change in Ukraine after Euromaidan?

The aftermath of Ukraine’s Revolution of Dignity provoked a lot of criticism among the students of LGBT topics. The principles of non-discrimination and protection of LGBT rights are an exemplary manifestation of European values to which Euromaidan declared adherence. The Association Agreement between Ukraine and the European Union, which was signed after the Revolution, as well as visa-free travel, which was granted to Ukrainian citizens, obliged this country to liberalise LGBT-related laws due to the EUʼs policy on the instrumentalisation of LGBT rights. However, there is a view that this step may cause conflicts in Ukrainian society, which is still predominantly homophobic, and only lead to a superficial change in the condition of LGBT people owing to pressure from the European Union. Some scholars (e.g. Shevtsova [2020], Wannebo [2017]) claim that the instrumentalisation policy has even resulted in a backlash against the LGBT community and worsened the overall situation for them. But has this backlash (if it really happened) entailed a corresponding change in public opinion on LGBT issues? Surprisingly, the dynamics of public attitudes towards the LGBT community and their rights remain unexplored. The paper proposes to fill this gap by a comparative analysis of two cross-sectional surveys on this topic, which were conducted before (in 2013) and after (in 2016) the Revolution of Dignity in several regions of Ukraine. Within the framework of the study, three research questions have been posed: 1. Have Ukrainians’ attitudes towards the LGBT community changed since Euromaidan? 2. How different (e. g. positive) were the attitudes towards LGBT people among Euromaidan supporters? 3. Have the events that happened after the Revolution of Dignity, such as Russia is hybrid war against Ukraine, been able to affect attitudes towards LGBT rights? The results show that there have been modest, albeit statistically significant positive changes in Ukrainians’ attitudes towards the LGBT community since Euromaidan. However, practically no change in terms of support for LGBT rights has been recorded. Our findings are consistent with other relevant nationally representative surveys according to which public perception of LGBT individuals has not worsened. This fact suggests that the instrumentalisation of LGBT rights has not faced any backlash, at least from the general population. Other data in our study indicate that not all proponents of the Revolution of Dignity displayed favourable attitudes towards LGBT people; nevertheless, they held more positive views on the LGBT community and same-sex marriage than those who did not take part in Euromaidan. The respondents who have experienced the impact of the Donbas conflict also demonstrated relatively better attitudes to LGBT individuals and expressed support for their rights. Still, this may be linked to a significant percentage of Euromaidan participants among them.
