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.

<p>Reducing air pollution, which is the world's largest single environmental health risk, demands better-informed air quality policies. Consequently, multi-scale air quality models are being developed with the goal to resolve cities. One of the major challenges in such model systems is to accurately represent all large- and regional-scale processes that may critically determine the background concentration levels over a given city. This is particularly true for longer-lived species such as aerosols, for which background levels often dominate the concentration levels, even within the city. Furthermore, the heterogeneous local emissions, and complex dispersion in the city have to be considered carefully.</p><p>In this study, the impact of processes across a wide range of scales on background concentrations over Switzerland and the city of Zurich was modelled by performing one year of nested European and Swiss national COSMO-ART simulations to obtain adequate boundary conditions for gas-phase chemical, aerosol and meteorological conditions for city-resolving simulations. The regional climate chemistry model COSMO-ART (Vogel et al. 2009) was used in a 1-way coupled mode. The outer, European, domain, which was driven by chemical boundary conditions from the global MOZART model, had a 6.6 km horizontal resolution and the inner, Swiss, domain one of 2.2 km. For the city scale, a catalogue of more than 1000 mesoscale flow patterns with 100 m resolution was created with the model GRAMM, based on a discrete set of atmospheric stabilities, wind speeds and directions, accounting for the influence of land-use and topography. Finally, the flow around buildings was solved with the CFD model GRAL forced at the boundaries by GRAMM. Subsequently, Lagrangian dispersion simulations for a set of air pollutants and emission sectors (traffic, industry, ...) based on extremely detailed building and emission data was performed in GRAL. The result of this nested procedure is a library of 3-dimensional air pollution maps representative of hourly situations in Zurich (Berchet et al. 2017). From these pre-computed situations, time-series and concentration maps can be obtained by selecting situations according to observed or modelled meteorological conditions.</p><p>The results were compared to measurements from air quality monitoring network stations. Modelled concentrations of NO<sub>x</sub> and PM compared well to measurements across multiple locations, provided background conditions were considered carefully. The nested multi-scale modelling system COSMO-ART/GRAMM/GRAL can adequately reproduce local air quality and help understanding the relative contributions of local versus distant emissions, as well as fill the space between precise point measurements from monitoring sites. This information is useful for research, policy-making, and epidemiological studies particularly under the assumption that exceedingly high concentrations become more and more localised phenomenon in the future.</p>

Introduction. Th e study of the infl uence of air pollution on the health of the population of industrial cities is an urgent task of preventive medicine.The purpose of the study— assessment of risk for population health of the city of Novokuznetsk, associated with the receipt in atmospheric air of polluting substances from SC «Kuznetsk TPP».Materials and methods.The paper presents the results of risk assessment for the health of the population of Novokuznetsk from the impact of atmospheric emissions of coal thermal power plant. Risks were calculated in accordance with the «Guidelines for the assessment of public health risks from exposure to chemicals that pollute the environment».Results.It was found that sulfur dioxide, coal ash, nitrogen dioxide had the largest share in the index of non-carcinogenic hazard of emissions. Th e maximum hazard index of carcinogenic substances was detected in hexavalent chromium. Th e greatest risk of immediate action, manifested in the development of refl ex reactions, was detected at two points of exposure to concentrations; it was determined by the infl uence of coal ash. In the formation of the risk of chronic intoxication, coal ash, sulfur dioxide, nitrogen dioxide, nitrogen oxide had the greatest impact; the greatest risk was detected at three points. Th e hazard coeffi  cients of the concentrations ranged from 2.04×10–4 to 6.723. The maximum index of danger equal to 29.31, corresponded to the residential district of Lenin square. Th e highest levels of carcinogenic risk identifi ed at three points were determined by exposure to hexavalent chromium.Conclusion.Th e work identifi ed environmentally disadvantaged neighborhoods of the city. It is shown that the main contribution to the formation of non-carcinogenic risk of health disorders of the city’s population is made by nitric oxide and nitrogen dioxide, coal ash, sulfur dioxide. Th e main carcinogen is hexavalent chromium. Th e total values of risks expressed in the multiplicities of excess of acceptable risk, for most points exceed 1, indicating a signifi cant impact of emissions on the health of the population. A set of atmospheric protection measures aimed at reducing risks to public health is recommended.

Number of vehicles moving in the city of Denpasar is quite dense and has the potential to produce high carbon monoxide (CO) and hydrocarbon (HC) exhaust gases which can be fatal to human health. The research objective is to analyze the level of air pollution in the city of Denpasar and analyze the factors that cause pollution from motorized vehicles. To calculate the volume of traffic using the application traffic counter on an android phone. The research method uses trend analysis and multiple linear regression analysis. The growth of CO pollutants in the city of Denpasar increased with a growth value of 0.88 to 3.25 per year so that in 2021 the level of CO is predicted to be between 32.41% to 81.52%. Likewise, HC levels increase with a growth value of 0.85 - 1.59 per year so that in 2021 HC levels are predicted between 2,670 ppm to 24,383 ppm. The vehicles age and engine combustion system have a strong correlation in producing CO and HC values; while brand, engine capacity and mileage correlate very weak. The conclusion is that newer vehicles and the latest combustion systems produce lower CO and HC levels.

Introduction. The Kemerovo region is the largest coal-producing region in Russia, and coal mining hurts the environment. The earth's developed mineral deposits are sources of pollution of atmospheric air, water, and soil. They increase the risk to public health. The implementation of measures for the reclamation of disturbed land is an urgent problem. The study aims to assess the health of an industrial city from air pollution during the liquidation of mining operations, and reclamation works carried out at a coal mine. Materials and methods. The scientists assessed the distribution and impact of atmospheric emissions at 40 plotted points based on a map of the city of Kisilevsk in the Kemerovo region. We calculated the maximum and average annual concentrations of pollutants and identified the risk of chronic intoxication and carcinogenic risk. Scientists obtained risk values with acceptable levels. The risk values were determined, taking into account the background concentrations of substances. Results. The researchers revealed priority pollutants: inorganic dust, nitrogen dioxide, nitrogen oxide, sulfur dioxide, carbon (soot), carbon monoxide. There is no excess of the maximum average annual concentrations during the liquidation and reclamation at the coal mine for all pollutants. The combined values of the risk of chronic intoxication and carcinogenic risk do not exceed the acceptable level. The total values of the risk of chronic intoxication, taking into account the background concentrations of pollutants, exceed the proper level at all points of exposure. Conclusions. Activities for the elimination and reclamation of mine workings do not significantly impact the environment and the health of the population of the city of Kiselevsk.

The contemporary sea walls built in the pedestrian seashore zone in the City of Acre, Israel, were sided with porous calcarenite sandstone, so-called ‘kurkar’. Kurkar stone has been broadly used as a durable building material in Acre and Jaffa, the Eastern Mediterranean offshore cities, since ancient times. Therefore, the contemporary urban architectural plans obligate kurkar siding in the modern structures erected beside the Old City of Acre. However, a rapid deterioration of kurkar siding had occurred in the contemporary sea walls during only a few years. In contrast, the Historic walls built of kurkar dimensional stone have been still sound. The current study has evaluated the factors and causes of kurkar deterioration in the modern seawalls. It was revealed that the main reason for deterioration was adhering the kurkar siding with cement mortar and the next exposure of adhered siding to the humid and salt-enriched offshore environment with high air pollution.

Abstract Environmental air pollution is a global health concern, a complex phenomenon which is directly reflected on public health, economic and human development. Environmental air pollution has been drastically multiplied, followed by the beginning of the new Millennia in Prishtina, the capital city of the Kosovo. The new millennium began as a crucial activity for the city of Prishtina in terms of demographic, human geography, social and economic phenomena. The presented study aims to determine prevalent traffic and land morphology composition attributes, which have influenced and continue to have environmental impact in the city of Prishtina. According to the conceptual findings from the empirical observations, the heavy city traffic and the land morphology structure, determine the urban air pollution level. Prishtina is generally polluted due to its geomorphic position in relation to the power plants Kosovo A, and Kosova B. The impact of the above cited factors, is even bigger when the dominant winds prevail through valley, which encompasses the city. The findings from this paper propose the necessity of careful driven urban solutions.

Corrosion is one of the main causes of early failure of infrastructure both for public housing facilities and public facilities in downtown Langsa. This corrosion is caused by air pollution generated from motor vehicle and household industry exhaust fumes and exhaust smoke from the nearest palm oil mill industry from the city of Langsa. Related to air pollution, its sustainability should be a concern regarding environmental impacts that occur, one of which is atmospheric corrosion. This study aims to analyze the impact of the effects of pollution on infrastructure corrosion on construction steel which is often used on infrastructure in the city of Langsa and the palm oil mill industry. There are five types of steel model infrastructure consisting of strips of plate steel, elbow steel, cylinder steel, plate steel, and low carbon steel market have become specimens. Calculation of corrosion rate using the method of mass loss by reference to ASTM standard G50, the location selected above buildings in downtown Langsa and palm oil mill industry. The results of the study for one year showed the level of corrosion rate that occurred in 5 types of steel construction is still relatively safe or its relative corrosion resistance can be classified in the outstanding category (<1 mil per year). The conclusion is that 5 types of construction steel that have been tested, are resistant to corrosion, and are suitable for use as the main construction material in Langsa City and the palm oil mill industrial environment.

Roadside Environment

The development of the COVID-19 pandemic and the related lockdown had a major impact on vehicle traffic in cities. Based on available data from the selected city of Rzeszow, Poland, it was decided to assess changes in vehicle traffic and the impact of these changes on roadside environmental pollution. As part of the research, data from the first half of 2020 regarding vehicle traffic on selected streets of the city and on the city’s inlet routes were analyzed. For the selected road sections, changes in hourly traffic volume in 2020, compared with 2019, were also determined. With data on traffic volume, an attempt was made to estimate the impact of changes in traffic volume on air pollution in the city. Research on air pollution from motor vehicles was focused on a selected section of a city road that was equipped with an automatic air pollution measurement station located very close to the road. Additionally, at the road intersection and in the vicinity of the measuring station, a sensor was installed in the roadway to count passing vehicles. A preliminary analysis of air pollution data revealed that factors such as wind speed and direction and outside temperature had a large impact on measurement results. To eliminate the influence of these factors and to obtain data concerning only contamination originating from motor vehicles traveling along the road, an appropriate mathematical model of the traffic flow–roadside environment system was built. This model was designed to determine the air pollution in the vicinity of the road generated by traffic flow. The constructed model was verified, and the conditions for its use were determined in order to study the impact of traffic and roadside environment on the level of air pollution from harmful exhaust substances. It was shown that at certain times of the day, especially at low temperatures, other sources of harmful emissions related to home heating play a major role in air pollution in the city.

This article discusses the impact of suspended particles on human health, by providing small definitions of PM2.5, including how they appear, what particles they consist of, and how they harm the respiratory and circulatory systems.  In addition, the analysis of the pollution level of the city of Almaty for the last three years from March 22, 2017, to October 6, 2020, with categorical intermediate values of suspended particles was carried out. Careful work was done with the SCV file such as data was skipped in the cells, that is, there were empty values; translation to a single data type; filling in empty cells. It also considers making a decision on the six categories provided to identify the average meeting categories. The authors identified specific categories based on digital readings of values received from sensors, where each category has its own verbal values that are understandable for each person. The indicator displays with weights as a graph for a specific Seifullin-Dulatov sensor location with categorical and without categorical division. Then for each intersection or location of the sensors is shown in a table. It is also revealed which level or category is the rarest among the others and the most common category as well.
