Analysis of air pollution by pollutants, sources of pollution, types of economic activity, and administrative areas in the city of Novokuznetsk over 5 years was carried out. The largest share in the city air emissions is accounted for: CO – 61.8 %; SO2 – 17.4 %; solids – 11.3 %; NO2 – 5.9 %; CH4 – 1.8 %. Dynamics of gross emissions by years is shown. Planned implementation of the approved measures of the national project Ecology will make it possible to reduce air pollution in the city by more than 20 % by 2024, which corresponds to the federal project Clean Air. According to planes of the city industrial enterprises, environmental programs have been prepared, with monitoring by environmental specialists from the city administration and public control. Various measures were taken: automatic stationary posts were put into operation to monitor air pollution in real time; mobile laboratory was acquired to measure urban air. To improve waste management in the city, separate collection projects were implemented. Environmental assets exist and develop in the city, which ideas and projects find common understanding and form ecological attitude of the urban community. Trends in gross emissions of pollutants into the atmosphere of Novokuznetsk are shown for the period of 2014 – 2018; refinements and explanations of the observed trends are given.

Studies show that Tehran is one of the most polluted cities in the world. This pollution is more due to the traffic of cars. According to statistics, Tehran only had 3 days of clean air in 2012 and 2013. The consumption of low-grade petroleum products by non-standard vehicles manufactured with old technol- ogy has caused air pollution to the city in the absence of an efficient public transport system as well as inefficient management. The results suggest that transition from this dilemma is possible through efficient laws, proper man- agement, the use of world-wide knowledge and culture and general education from the basic levels. Obviously, solving this problem will directly affect the quality of life of citizens, and its effects can be seen in the economic, health, environmental and social spheres. The indirect effects of the crisis can be predicted in economic growth and development, and even in the promotion of national security (at a high level).

Abstract: Air Pollution has become one of the significant factors behind the increase in world-wide mortality rate. There are several reasons behind this increased rate such as rapid growth of industrialization, vehicular pollution accompanied by increase in urbanisation and burning of fossil fuels. This paper presents the proper management and mitigation plan (action plan) of air pollution scenario for the city Prayagraj based upon emissions. Some major air pollutants under consideration in the city of Prayagraj are Particulate Matter (PM10) and particulate matter (PM2.5). There are several prominent sources within and outside prayagraj contributing to PM10 and PM2.5 ambient air; these pollutants can be taken as surrogate of other pollutants also, as most of the pollutants coexist and have common sources. Several major sources of pollution in the city have been noted such as from Domestic, Vehicular Pollution, Road dust, Municipal solid waste (MSW) and Brick kiln. Based upon emissions calculated from these major sources a proper mitigation and management plan has been prepared for the city. Keywords: Air pollution, Particulate Matter, Prayagraj city, Action Plan, Emissions.

The problem of air pollution of the city is still relevant today. A significant increase of emissions of pollutants from the activities of industrial plants, road transport has a negative impact on the quality of atmospheric air and the environment as a whole, the health of the population. The main objective of this research is to assessment of the state of the air environment, by studying of pinus sylvestris needles, growing on the territory of the city of Omsk. For research of the state of the atmospheric air were chosen 5 key sections in the city of Omsk, where we selected samples of needles. It was found, that the severity of damage and drying of needles is uneven on all key sections, depends on the level of air pollution. An assessment of the state of the air environment was carried out, which showed, that on the territory of the Soviet park and ave. of the Culture (sections 1 and 2, respectively) relatively clean air "norm" was established, according to the third level of pollution. Cathedral square and st. Irtyshskaya embankment (sections 3 and 5, respectively) are characterized by dirty air «harmful», according to the sixth level of pollution.

The city of Zarghan is located 25 km northeast of Shiraz, southern Iran. Zarghan is affected by numerous pollution sources such as oil refinery, an industrial park, and Shiraz-Tehran highway. The numerous contaminating sources around Zarghan can cause serious local air pollution. Sulfur dioxide gas is an important index of air pollution in cities. Therefore, in order to control and manage Zarghan air quality, it is important to monitor sulfur dioxide concentration in the surrounding area. It is also essential to know about the contribution level of other sources of pollution as well as dispersion radius of pollutants in the area. In this study, the concentration of sulfur dioxide was measured by passive sampling at 10 different stations. These values were interpolated in other parts of the city using ArcGIS software. The results of sampling showed that the concentration of the gas was 60 µgm−3around oil refinery. The level was 19 µgm−3in region located about 3 km from the oil refinery. It was also demonstrated that the gas concentration was not higher than the standard limit within residential area. On the other hand, the role of the local highway and industrial park was not significant in contaminating air in urban areas.

Together with the urbanization, industrial activities are increasing and transportation system is being rapidly developing. In 2017, the population of Ho Chi Min city (HCMC) is over 8.6 million. The city has 8 million vehicles including 637,323 automobiles and more than 7,339,522 motorcycles. Up to now, the city has a total of 2708 factories generating air emissions (including 3 processing zones (EPZs) and 16 industrial parks (IPs), with thousands of factories outside the IPs / EPZs), resulting in an increase in emissions from these activities and affecting the air quality of the city. Therefore, in this study (i) collect air emission data, evaluate and calculate of air emissions by applying EMISENS emission calculation models and survey and traffic counting methods; (ii) Develop clean air action plan and climate change mitigation for Ho Chi Minh City. The results showed that on-road activities are the major contributor, accounting for 88% of NOx, 99% of CO, 79% of SO2, 99% of NMVOC, 88% of PM in total emissions from transportation activities. Key finding in this study is that harbour activities contribute up to 20% of total SOx and 10% of total PM. Other sources (airport, harbour, bus station, rail way) only accounting for negligible amount of emissions. Emission maps showed that emissions in harbours and in central areas of the city as District 1, district 10, district 3 and district 5 are higher than the other districts. This study has also developed 13 measures to effectively manage air quality and reduce GHG in Ho Chi Minh City.
