Ambient air pollution is emerging environmental problem in major cities of Pakistan. Service sector growth is 8% and there is a rapid development of infrastructure in cities especially in transport sector which causes ambient air pollution issues in mega cities. To estimate the level of pollution in the city of Lahore, ambient air quality mapping procedure was used with the help of Haz Scanner HIM-6000 equipped with different sensors and ArcGIS 10.3 software was used for mapping of these pollutants. This study continued for two months from September to October, 2017 for different pollutants like PM2.5, VOCs, Ozone, NOx, CO2, CO, SO2 and H2S. From the study, it was concluded that ambient air in Lahore has lot of pollutants especially PM2.5, NO, NO2, CO, SO2 where as conc. of VOCs, H2S and Ozone was in limits in relation to NEQs for these pollutants.

Abstract We can’t stop breathing, but we can do something about the quality of air that we breathe. Clean fresh air is indispensable ingredient for a good life quality. Individuals poses the right towards expecting that the breathed air will not harm people. Thus, fighting air pollution will not only improve health outcomes, productivity, and well-being, it’s also essential toward reducing the emissions of greenhouse gas as well as fighting climate change. For examples, a third of the global population is at risk from unhealthy of ambient air pollutants concentrations, with the loss of approximately 6.4 million healthy-life-years attributed specifically to chronic exposure to ambient particulate matter. Expert panels have consistently rated air pollution as a greater health hazard than water pollution. Pollution of air is the leading source of unexplained and undiagnosed diseases, besides have remained associated with a variety of serious human health risks, and in fact, a threshold has not been established under which these pollutants exert no adverse effects. This study evaluates ambient air quality at major sawmill sites in Ilorin Metropolis, Kwara State, Nigeria. “Measurements of Air pollution were accurately carried out using direct reading, automatic in situ gas monitors; Hand held mobile multi-gas monitor with model AS8900 [Combustible (LEL), and Oxygen (O2)], BLATN with model BR – Smart Series air quality monitor (PM10, Formaldehyde) and air quality multimeter with model B SIDE EET100 (Dust (PM2.5), VOC, Temperature and Relative Humidity)”. The outcomes disclosed among others, the average concentrations of CO, O2 as well as other measured parameters for instance formaldehyde (HcHo) etc., they are also consistently low as well as within acceptable range in terms of National as well as Global monitoring standards for air quality indices. However, there are few exceptions for instance the average volatile organic compounds (VOCs) concentrations, PM2.5, PM10 as well as Combustible (LEL) respectively, which are higher when compared to National and Global standards. This high figure is due to pollutant amount existing in the sawmills air environment resulting from input of influents from activities of the sawmill. However, as a result, air pollution in the city of Ilorin is found to be increasingly polluted and are of major health concern because of their synergistic action. Due to the high evidences and values, it can lead to a remarkable rise in over-all figure of hospital visits/ patients’ admissions with acute respiratory illnesses as soon as air pollutants level remained high. Hence, there is the need for an aggressive control of ambient air pollution.

Based on an analysis of related core papers and reports, this review presents a historical perspective on ambient air pollution and ambient air quality development in the modern-day Czech Republic (CR) over the past seven decades, i.e., from the 1950s to the present. It offers insights into major air pollution problems, reveals the main hot spots and problematic regions and indicates the principal air pollutants in the CR. Air pollution is not presented as a stand-alone problem, but in the wider context of air pollution impacts both on human health and the environment in the CR. The review is arranged into three main parts: (1) the time period until the Velvet Revolution of 1989, (2) the transition period of the 1990s and (3) the modern period after 2000. Obviously, a major improvement in ambient air quality has been achieved since the 1970s and 1980s, when air pollution in the former Czechoslovakia culminated. Nevertheless, new challenges including fine aerosol, benzo[a]pyrene and ground-level ozone, of which the limit values are still vastly exceeded, have emerged. Furthermore, in spite of a significant reduction in overall emissions, the atmospheric deposition of nitrogen, in particular, remains high in some regions.

Background: We aimed to provide information for health practitioners and other related people about the association between ambient air quality and adverse health outcomes in the general population of Nigde, a central Turkish city, within the context of current health data epidemiological evidence. Methods: The present study highlights the connection between health problems and time series of particulate matter (PM10) and sulphur dioxide (SO2) in Nigde, Turkey between 2011 and 2017. Significant morbidity is linked to ambient air pollution, resulting in a significant economic cost to society. Results: We found that the required funds to treat cancers and chronic obstructive pulmonary disease triggered by ambient air pollution in Nigde, exceed 9 million US dollars per year, even when only the city center is taken into account. Conclusion: As Turkish cities grow and urban population density increases, air pollution issues need to be given priority in order to protect the health of the public and support sustainable development for future generations. It is recommended that particulate matter concentration in this urban center should be significantly reduced to minimize health problems.

Summary. Introduction: Within the framework of the Federal Clean Air Project, it is envisaged to implement comprehensive action plans aimed at reducing air pollution and increasing the level of public satisfaction with the environmental situation in a number of industrial centers of the Russian Federation with high and extremely high levels of ambient air pollution. Decree No. 1792 of the Russian Government of December 24, 2019 approved the requirements for compensatory measures aimed at improving ambient air quality, preventing and eliminating adverse health effects of environmental factors. To increase the validity and adequacy of the measures taken, it is necessary to elaborate method approaches for Rospotrebnadzor bodies to designing and conducting studies on establishing the association between air pollution and adverse health outcomes in the population living in industrially contaminated areas. The purpose of our work was to substantiate an algorithm of actions and to demonstrate its efficiency within epidemiological studies focused on establishing and proving the causal relationship between airborne chemicals and observed health consequences in the population. Materials and methods included a set of modern hygienic and epidemiological research methods, assessment of risk and its health damage, in-depth research, and modeling of cause and effect relationships. Results: We proposed approaches and conducted studies to establish the link between industrial air pollution and the diseases diagnosed in the exposed population. Conclusions: The suggested algorithm of actions tested in the city of Bratsk proved to be effective and helped identify risk-attributed health disorders; specify the pollutants requiring development or adjustment of measures to reduce their ambient emissions; clarify and expand the list of target organs and systems for prediction and monitoring; substantiate and fulfil managerial decisions and adequate targeted preventive measures based on health damage criteria.

Large proportions of the Indian population live in megacities (e.g., Delhi, Mumbai and Kolkata), which are vibrant centers of economic opportunities and offering better quality of social life. Due to increasing migration to these cities, Indian megacities are constantly expanding, which subsequently leads to strain on the environment with a range of impacts at local, regional and global levels. During the last few decades the anthropogenic emissions of greenhouse gases (GHGs) and other air pollutants have increased substantially, resulting in worsening ambient air quality of these cities. With respect to time span the concern over air pollutants has also changed in Indian megacities. Concern over particulate matter, black carbon, NOx and ozone has heightened recently due to their local and regional impacts on air quality and environmental (including public) health and also because they contribute to global climate change. Although authorities have implemented several measures to reduce air pollution and its impacts in Indian megacities, much more is yet to be done to improve their ambient air quality. This paper focuses on major air pollution and GHGs emission issues in Indian megacities and associated problems within the framework of their role in environmental vulnerability.

The issue of pollution in urban cities is a major problem these days especially in cities like the New Delhi is detected with more number of toxic gases in air, which has deduced the air quality of New Delhi. Thus, predictive analytics play a significant role in predicting the future instances of air quality based on the historical data. Forecasting the air quality of these cities is mandatory to overcome its consequences. Several machines learning algorithm is widely used these days to predict the future instances. Such as random forest, support vector machine, regression, classification, and so on. Main pollutants which present in the air are PM2.5, PM10, CO, NO2 , SO2 and O3 . In this paper we have focused mainly on data set of New Delhi for predicting ambient air pollution and quality using several machines learning algorithm.

This study aimed to examine the trend of ambient air pollution (i.e., ozone (O3), nitrogen monoxide (NO), nitrogen dioxide (NO2), nitrogen oxides (NOx), sulfur dioxide (SO2), carbon monoxide (CO), benzene (C6H6) and particulate matter with an aerodynamic diameter smaller than 10 microns (PM10), and non-methane hydrocarbons (NMHCs) at 10 monitoring stations located in the main residential and industrial areas in the State of Kuwait over 6 years (2012–2017). We found that the SO2 level in industrial areas (0.065 ppm) exceeded the allowable range of SO2 in residential areas (0.030 ppm). Air pollution variables were defined by the Environmental Public Authority of Kuwait (K-EPA). In this study, integrated statistical analysis was performed to compare an established air pollution database to Kuwait Ambient Air Quality Guidelines and to determine the association between pollutants and meteorological factors. All pollutants were positively correlated, with the exception of most pollutants and PM10 and O3. Meteorological factors, i.e., the ambient temperature, wind speed and humidity, were also significantly associated with the above pollutants. Spatial distribution mapping indicated that the PM10 level remained high during the southwest monsoon (the hot and dry season), while the CO level was high during the northeast monsoon (the wet season). The NO2 and O3 levels were high during the first intermonsoon season.
