В статье исследовано состояние загрязнения атмосферы и заболеваемости населения на территории г. Владикавказа за пятилетний период. Установлена тенденция к снижению выбросов в окружающую сре- ду главным образом за счет уменьшения объемов производств и выполнения природоохранных меропри- ятий на промышленных предприятиях города. Вместе с тем, отмечается рост количества автотранспорта и его техногенная нагрузка на среду неуклонно увеличивается. State of air pollution and the incidence of population on the territory of Vladikavkaz city for the five-year period are investigated in the paper. The tendency of reduction of emissions into the environment (mainly due to the reduction of production volume and implementation of environmental activities at the industrial enterprises of the city) is stated. At the same time, number of vehicles and corresponding anthropogenic impact on the environment are steadily increasing

Atmospheric pollution arising from diesel-powered engines can result in acute and chronic diseases of the respiratory and cardiovascular systems. The annual carnival festival that takes place in the city of Salvador, Bahia-Brazil, is a large-scale event that gathers approximately 2 m revelers and 170,000 workers who accompany dozens of sound-trucks, or trios elétricos, for a period of seven days. These slow-moving sound-trucks run on diesel fuel, constantly exposing those around them to exhaust fumes. The present study aimed to evaluate air quality along the approximately 10km-long carnival parade circuit and determine possible impacts on human health. We applied a three-phase risk analysis strategy from 2007–2009: 1) hazard identification, 2) risk characterization and 3) risk management. Our quantification of atmospheric particulate matter 2.5 (PM2.5) and nitrogen dioxide (NO2) concentrations revealed variable levels of PM2.5 ranging from 19 µg/m3 to 580 µg/m3, with peaks of up to 800 μg/m3 at sound-truck concentration areas. We then assessed the effects of air pollution on human health using ophthalmologic parameters obtained from 28 carnival volunteers, who often presented symptoms of eye irritation. Finally, we established strategies to communicate the study’s objectives and obtained results to the population through media outlets and open discussions with government agencies. According to our risk analysis, carnival sound-trucks represent the main source of atmospheric PM2.5 and NO2 pollution during the annual 7-day carnival festival. As a consequence of our research, the municipal government of Salvador issued an addendum to its carnival legislation mandating organizers to monitor atmospheric pollution, and, subsequently, all large-scale public events. Municipal government authorities have also promoted a shift from petroleum-based diesel fuel to biodiesel, a less-polluting fuel, for all adapted carnival sound-trucks. Our approach, which employed easily accessible and inexpensive methodology, provided substantial scientific evidence to support improvements in the regulation of air quality during large-scale public events held in the city of Salvador.Keywords: environmental

Introduction. The issue of air pollution is relevant in cities where the majority of the population lives and a large number of industrial enterprises are concentrated in relatively small areas. Currently, the federal project “Clean Air” is being implemented in 12 industrial centres of Russia within the framework of the national project “Ecology”. The purpose of the work was to justify using statistical and mathematical methods for assessing the impact of atmospheric pollution on the health of the population in the city of Novokuznetsk, Kemerovo region. Materials and methods. The following methods were used: assessment and management of public health risk, statistical analysis methods: factor analysis, multiple regression analysis, discriminant analysis. Results. Statistical indices and public health risk parameters can be used to assess the impact. Examples of the effect of complex pollution indices (the main components of pollution, the integral indicator P) and the concentrations of individual impurities in the air basin (suspended substances, ozone) were given. The carcinogenic risk to the population of Novokuznetsk, calculated from the calculated concentrations of atmospheric pollutants, was found to exceed the acceptable risk threshold. The specific weight of carcinogens in the formation of the risk to other oncological incidence was determined. An assessment of the risk from the emissions of a coal-processing plant located near residential areas of the city was carried out. The values of the hazard indices showed an excess of the acceptable non-carcinogenic risk only from the emissions of the coal processing plant, taking into account the background level of air pollution in the air basin. Conclusion. In Novokuznetsk, it is proposed to use the method of ranking atmospheric protection measures in terms of the unit cost of risk reduction in health risk management. To manage the risk, it is proposed to calculate the population indices of aerogenic hazard or the probabilistic parameters of the individual threat associated with air pollution. It is noted that a 20-22% reduction in pollutant emissions for Novokuznetsk may not be enough. The reasonable measures for the further study of the aerogenic impact on the population of the city are presented.

One of the regions of Ukraine, which is subject to significant man-made impacts on the atmospheric air, is the city of Zaporizhzhya. The paper presents the results of assessing the quality of atmospheric air based on the calculation of the air pollution index and the integrated air pollution index of the city of Zaporizhzhya. For the assessment, the data of long-term observations at the stationary posts of the city for 2016—2020 were used for the main pollutants. A list of the main pollutants (formaldehyde, dust, carbon monoxide, phenol, nitrogen oxides, sulfur dioxide) and the contribution of each of them to the general level of atmospheric pollution has been determined. The calculations of air pollution indices were carried out for the average daily concentrations of substances for each observation post in Zaporizhzhya for the study period 2016—2020. The calculation of the air pollution indices for the posts was carried out for all concentrations of the investigated substances, except for hydrogen sulfide due to the lack of data for it. The highest values of the indices are observed in 2017 and 2019, the lowest — in 2020. Over the past year, there has been a tendency towards a slight decrease in the level of air pollution by pollutants. The highest values of indices exceeding 1 are noted for substances such as dust, nitrogen dioxide, nitrogen oxide, phenol and formaldehyde. Calculations of the integrated index of atmospheric pollution at posts showed their heterogeneity, the list of measured substances is not unified for all posts. Formaldehyde, nitrogen oxides, phenol and dust make the largest contribution to the formation of the integrated air pollution index. Environmental monitoring in the city of Zaporizhzhya does not include measurements of hazardous toxicants, the presence of which is typical for large cities. The highest level of the integrated air pollution index is observed at the posts located in the zone of influence of the main industrial site, and reaches values of 5,4—9,8, which corresponds to a high level. In other areas of the city, where there is industrial potential, observations are not carried out; it is impossible to assess the level of air quality according to the data of the hydrometeorological service.

The article represents a retrospective review of long time research of genesis and development of the Central beach in the City of Varna which makes possible a forecast of its further development. Both natural and anthropogenic impact on the beach evolution is taken into consideration. It is ascertained that construction of coastal protection structures at the northern part of the beach in 80’s resulted in cessation of natural beach area growth. The strengthen of a breakwater in the main port and illegal building also contributed to considerable coast recession and beach volume reducing. Because of this a recreational potential of the Central beach is gradually decreasing. New method named “cross-shore sediment bypassing” is suggested to reduce the negative trend.

Firm Entry And Exit

The impact of environmental regulation has been an important topic. Based on the Chinese Custom Database and China City Statistical Yearbook, this paper investigates the effect of environmental regulation on export values and explores potential mechanisms and heterogeneous effects. Taking advantage of China’s first comprehensive air pollution prevention and control plan, the Air Pollution Control in Key Zones policy, as a quasi-natural experiment, we employ the difference-in-differences method to examine the causal relationship between environmental regulation and exports. We find the statistically significant and negative effect of environmental regulation on exports at the city level. Moreover, we find that the potential mechanism is the change in export values caused by firm entry and exit, especially by exiters, rather than the change in the number of exporting firms in the city caused by firm entry and exit. In addition, we find the heterogeneous effects of environmental regulation based on the differences of environmental policy across cities and the Broad Economic Categories classification.
