Climate change has become an important issue since 196 countries in the world agreed to sign the Paris Agreement at COP21 in 2015. This is an important issue because Climate change has a wider impact in the long term such as rising air temperatures, increasing volume of sea water, extreme and unpredictable weather changes, shifting populations and wildlife habitats and affecting human health. One of the causes of climate change is air pollution produced by burning conventional vehicles or we can call Internal Combustion Engine (ICE). For this reason, various countries in the world are innovating by converting fossil-based vehicles into electric vehicles with the main raw material being batteries. As a result, several countries in the world such as Japan, Brazil, Germany, France and Sweden have succeeded in reducing their emission levels in the 2015-2018 period by starting to develop electric vehicles. This paper was conducted through literature study and in-depth analysis using qualitative research methods. This paper aims to analyze whether the transformation from an internal combustion engine-based vehicle to an electric vehicle is able to reduce the level of emissions in a country in order to overcome the problem of climate change. In addition, this paper also analyzes other supporting factors to find the right solution to overcome the problem of climate change. [ABSTRACT FROM AUTHOR]

The environmental impact of physical and chemical pollution is one of the most relevant problems nowadays. In order to monitor the chemical air pollutants concentrations, field measurements can be performed. Data recorded in strategical areas can be used to calibrate predictive models, useful to produce predictions for following periods and to help administrations in protecting people from high and risky exposure. In this paper, the ARIMA (AutoRegressive Integrated Moving Average) technique is applied to a dataset of CO concentrations in San Nicolas de Garza, one of the twelve municipalities of the Metropolitan Area of Monterrey. The results will show that the hourly data allow to build a model that gives a reliable prediction on a short time range. The main shortcoming of the ARIMA models, in fact, is that they adopt data measured in previous periods to build the future forecasts, thus the prediction cannot be extended to any future time period. The specific models presented in this paper can be used to predict maximum 24 hours in the future, resulting in a compromise between precision and forecast horizon. This could be very useful for policy maker, in order to apply extraordinary counter measures for keeping the pollution below the regulation thresholds. [ABSTRACT FROM AUTHOR]

The palm oil industry is one of the most important agro-based industries in Malaysia, with more than 400 palm oil mills nationwide. These mills are generally self-sustained in energy by converting empty fruit bunch (EFB), palm mesocarp fibre (PMF) and palm kernel shell (PKS), into energy. However, palm fuel burned in boilers have caused severe air pollution problems due to improper boiler operation and inefficient air pollution control systems. This results in emission of bottom ash particulates from multicyclone and electrostatic precipitator (ESP) hopper after combustion. This paper discusses the characteristics of palm fuel, namely PMF, PKS and EFB, based on proximate analysis, gross calorific value, ultimate analysis and element composition. Morphology of bottom ash emitted from multicyclone and ESP was also examined using scanning electron microscope (SEM). EFB was found to have the ' highest moisture content of 63.1% among others, while mixture of PMF and PKS had the highest volatile matter of 54.5% and fixed carbon of 18.5%. PMF has the highest calorific value of 2993 kcals/kg among others. The bottom ash from multicyclone and ESP exhibited particulate sizes ranging from 18.4 to 68 µm and 10.9 to 44.6 µm, respectively. These were considered as preliminary results which require further future research. The outcomes of this study are useful for mitigation of fine particulate emission from air pollution control system in the palm oil mill. [ABSTRACT FROM AUTHOR]

Emission-free economy is an achievable target with the formulation of policies by the Governments around the globe. A major contribution is made by the transport industry. Delhi is one of the examples among the cities in India which is polluting the air by transportation which is about 20 percent. Towards achieving the Sustainable Development Goals, the nation has to take a different trajectory from concentrating on the technical aspect of reducing the hazardous emissions to refining the regulatory awareness. The research study is based on the statistical inputs provided by the government agencies and the judicial verdicts seeking a pollution free atmosphere. The Judiciary has been proactively recommending and directing the respective government to take necessary action towards controlling the pollution caused due to road transport. Nevertheless, the use of Artificial Intelligence has been an area which has not been strongly recommended by the apex court. The regulatory and judicial control over the emissions is towards a penalizing perspective and the technological assistance has not been resorted to. Though a one hundred percent emission-free economy is not a possibility, the areas which are still not explored or have not been brought under the purview of consideration have been the scope of study in the research paper.

Commercial areas consider a center of attraction for large numbers of citizens for the purpose of shopping and trade exchange, and thus traffic increases in commercial areas. The commercial areas are among the most places in city centers that suffer from traffic congestion, and consequently, the burning of motor fuels. In this paper, air pollution resulting from crowded and irregular traffic in the main commercial center of Al-Diwaniyah city in southern Iraq was studied. It covered an area of 4 km2 for the emission and spread of air pollutants resulting from traffic movement. Air pollution tests for particle matter, gases, and atmospheric measurements were conducted during the year 2021 using the air pollution monitoring system. Field measurements of air pollutants were compared with a mathematical model for the purpose of calibrating and adopting it in the future prediction of the spread of pollutants according to traffic movement and according to geometry designs for roads, and the change in the vehicles number, vehicles types and speed of different transportation. the results of air pollution was compared with WHO limitation. The results showed a significant increase in the air pollution quality index (AQI), reaching 300, and it is considered among the dangerous areas for this indicator. The results showed a match of up to 98% between the results of the mathematical model and the field measurements. [ABSTRACT FROM AUTHOR]

The utilization of bio-briquette fuel for rural kitchens would reduce dependence on firewood and, subsequently, air pollution. To fabricate bio-briquettes from biomass, it is necessary to pay attention to the basic properties of the materials used in order to understand their potential as a fuel. This paper particularly examines the basic characteristics of rice husk biomass waste in terms of its physical and chemical properties as a first step to determine its potential as a bio-briquette material. The results showed that the physical properties of rice husks are dominated by volatile matter 61.18 wt.%, indicating an excellent fuel reactivity during devolatilization. The calorific value of 14.63 MJ/kg was observed, indicating that the energy that would be released during the combustion process would be sufficient. The chemical characteristics of rice husk showed that the carbon, oxygen, sulfur, nitrogen, and hydrogen content were 35.85; 31.22; 0.12; 0.98, and 5.75 wt.%, respectively. Rice husk is dominated by C and O elements that are believed to be able to effectively contribute to increasing fuel volatility. [ABSTRACT FROM AUTHOR]

Gaussian models are the important tools in the development of successful emergency response strategies of air pollutants or hazardous materials. As numerical dispersion models via predicting the influencing area affected by the passage of hazardous gas, Gaussian models are extremely important in leaking emergency response. The Gaussian Puff model and the Gaussian Plume model have been wildly used in calculating mesoscale dispersion of air pollutants from point sources. In the meantime, the Gaussian Puff model is suitably used in instantaneous dispersion while the Gaussian Plume model in continuous dispersion of invariable intensity. Little to no attention has been given to simulate the chemical accident of dispersion in variable intensity, which the accidents cannot either be considered as instantaneous dispersion or continuous dispersion as well. This paper proposed the Accumulated Gaussian model for such instance of dispersion in variable intensity take place in pipeline or in tank. This paper also discusses a case of chemical spill, in which Accumulated Gaussian model has been used to modify the situation at the time. [ABSTRACT FROM AUTHOR]

Air pollution is one of the main factors causing adverse health effects, such as cardiovascular disease, morbidity, and even mortality to humans. In the urban environment, transport is known to be the primary source of air pollution. This paper aims to assess people awareness of air pollution in open public spaces by investigating the relationship between people's dwell time and traffic-induced pollution at sidewalk café/restaurant. First, air pollution was analysed by descriptive statistics. Next, correlation and multivariate analysis were used to seek the relations between traffic, air pollution, and dwell time. The results show that pollution level doesn't significantly influence people duration of stay, but traffic does. It portrays the unawareness of people towards air quality in their surroundings. Furthermore, the unexpected result found in this study is that there are other significant pollution sources such as from cooking and smoking activities. Therefore, policies to improve air quality in urban areas are highly needed from the transport sector and eventually beyond it. [ABSTRACT FROM AUTHOR]

Sustainability, environmental sustainability, and sustainable transportation are all attracting attention currently, and the importance of sustainable transportation due to its effects on both the environment and society are now well acknowledged. However, although there has been an increasing number of projects and measures addressing sustainable mobility issues emerging in recent years, it can be difficult to compare outcomes, as there is not yet a set of globally applicable tools and indicators to guarantee comprehensive evaluation and to ensure the reliability of best practices. Maintaining sustainability is always a challenge, leading to this paper examining previous studies in detail to create a systematic overview of relevant and scientifically sound indicators for various aspects of sustainable mobility applicable in a range of social and economic contexts globally, particularly in terms of sustainability indicators for urban roads such as degree of congestion, traffic noise pollution, and traffic air pollution. This is important, as identifying such sustainability indicators is a significant factor in developing appropriate transport plans for any city. [ABSTRACT FROM AUTHOR]

Nowadays the world is largely dependent on conventional energy sources which are non-renewable and its demand is increasing day by day. The emission due to utilization of these energy resources causes air pollution and human disease. So researchers are focusing their attention on biodiesel as an alternative to diesel. Biodiesel while being renewable, environment friendly, has poor performance and higher NOx emission. To eliminate these problems up to some extent, blending with diesel can be done but increasing blending percentage again causes the same problem. To eliminate these demerits of biodiesel researchers are using nano sized particles as additives to biodiesel. A large number of nanoparticles are used as additives and resulted in improved performance and emissions, viz. increased "brake thermal efficiency", reduced "brake specific fuel consumption" (bsfc), lower release of Hydrocarbon (HC) and Carbon monoxide (CO) etc. Apart from poor performance, higher NOx release is the main concern with the use of biodiesel. Some nanoparticles reduce NOx emission while use of some other nanoparticles result in increased NOx emission. NOx emission varies with the concentration of nano particle as well. This paper reviews the research work in which nanoparticles such as CeO2, TiO2, GO, CaO, Al2O3, Bi2O3, SiO2, ZnO, NiO, Ag-O, CNT, MWCNT, nano water emulsion as well as combination of these nano sized particles have been used as additives to biodiesel or biodiesel blends.

Quasi-Monte Carlo algorithms based on Sobol, Faure, and different lattice rules are used in our sensitivity study of the Unified Danish Eulerian model. Different parts of the large amount of output data, produced by Unified Danish Eulerian model, were used in various practical applications, where the reliability of this data should be properly estimated. Another reason to choose this model as a case study here is its sophisticated chemical scheme, where all relevant chemical processes in the atmosphere are accurately represented. The numerical tests show that the stochastic algorithms under consideration, and especially the optimal lattice rule, are efficient for the multidimensional integrals under consideration and especially for computing small by value sensitivity indices. Clearly, the progress in the area of air pollution modeling, is closely connected with the progress in reliable algorithms for multidimensional integration. [ABSTRACT FROM AUTHOR]

The control object is the urban traffic of network of eight crossroad sections as a part of density populated area in Sofia. The goal is minimization of vehicle queue lengths in front of the junctions, which leads to faster driving, reducing the air and noise pollution and better ecological picture. The paper analyzes two types of modeling and optimizations, applied for the traffic control: classical optimization (one-level) and bi-level one. The bi-level optimization has the priority to co-ordinate the two-level hierarchical problem and to take into account the interconnections between the crossroad sections. It contains two goal functions, which are considered for the control process. The bi-level and classical one-level linear-quadratic optimizations are numerically applied for the traffic light control of urban network. The comparison gives preferences to the bi-level optimization, confirmed by numerical simulations. [ABSTRACT FROM AUTHOR]

The quality of air in deep mines is a very important aspect because of the health of the miners working there. Poor quality of the air might also affect the efficiency of their work. There are many possible sources of air pollution in a deep mine. One of the most critical issues is related to the usage of explosive materials for rocks fragmentation. Results of such explosions are carbon monoxide, extremely dangerous an odourless and colourless gas. In our research, we have received long term data from the online monitoring system installed in some part of the mine. The research task is to describe the behaviour of the concentration of CO gas in the air in the language of mathematics. So, finally, the analysis of carbon monoxide concentration variation associated with the blasting events has been proposed. It consists of the separation of the sub-process of the CO concentration related to the blasting procedure (process P) from the remaining part of the gas concentration and its modelling using the deterministic function.

Now a days, air pollution is a critical environmental issue in developing countries due to urbanization and industrialization. The pollution in air causes severe health issues for human beings, affects plants and animals due to acid rain, creates loss in economy, agricultural production and commercial production. In order to prevent or control it, the air quality forecasting necessitates. Accurate air quality prediction is a prominent task to be done to control the pollution level and to take countermeasures for securing the human life. The complex, uncertain and non-linear nature of the air quality pollutants impose complications in achieving accurate forecasting. The advent of artificial intelligence techniques helps to improve the air pollution forecasting results compared to traditional statistical methods at the great extent. This paper focuses the complications of air pollution, significance of air quality prediction, air quality index, and reviews the applications of machine learning and deep learning methods in air quality prediction. Literature shows that the machine learning and deep learning methods along with feature engineering and optimization techniques guarantees a promising air quality prediction. [ABSTRACT FROM AUTHOR]

Air pollution is a modern problem of high importance due to its negative impact on human health. The Organization for Economic Co-operation and Development (OECD) predicts that in 2050, air pollution will be the leading cause of environmental deaths worldwide. In addition, air pollution is classified as a major cause of cancer, related to the environment. In recent years, machine learning techniques have been used extensively to predict future values of time series. They can model nonlinear dependencies, allow the inclusion of large number of features and have weaker requirements than those of classical statistical methods.

In December 2019, the outbreak of Covid-19 does cause a lot of serious issues, fatality, economic crisis, the rise of the unemployment rate, air pollution, and so on. This paper focuses on the impact of Covid-19 that relates to the long-lasting issue of air quality. The scope of this study is focused on the changing of air quality that occurred within the Movement Control Order (MCO) which was launched by the Malaysian government against Covid-19 spreading in Malaysia. Multiple reports suggest during the MCO period, the overall air quality in Malaysia was improved. However, when we just look into the history of air quality index (AQI) value without doing any further analysis, we can see there is no significant difference between the AQI value since the MCO was executed. Therefore, we need to understand how AQI value is obtained and compare available data before MCO is launched to the first three phases of MCO. This paper estimates the impact of MCO towards reduction of moving vehicles which can give impact to air quality in terms of 24-hours PM2.5 concentrations. Air quality index data have been analyzed by developed code using MATLAB. From the investigating and analyzing the data conducted, we found out the impact of MCO on the air quality in Malaysia is positive. [ABSTRACT FROM AUTHOR]

Jakarta is one of the world's cities with unhealthy air quality, even during a pandemic. Unhealthy air quality is caused by air pollution from various activities, including industry, transportation, offices, and housing. Unhealthy air quality can cause many problems such as health problems, decreased productivity, financial losses, family economic problems, and social problems. The public can obtain many benefits by knowing the daily air quality prediction. Among them is that they can make preparations to protect themselves when the air quality is unhealthy. This paper aims to predict monthly air quality categories based on five indicators, namely Particulate Matter 10 µg (PM10), Sulfur Dioxide (SO2), Nitrogen Dioxide (NO2), Ozone (O3), and Carbon Monoxide (C.O.) using quadratic discriminant analysis. The model validation performance shows that discriminant analysis can predict the daily air quality category in Jakarta well. Performance measures the accuracy of 93.84%, the specificity of 96.80 %, the sensitivity of 90.41 %, the F1 score of 90.41 %, and the precision of 90.41 %. [ABSTRACT FROM AUTHOR]

This paper presents the utilizing the non-degradable waste such as construction and demolition wastes and plastic waste. Utilization of these wastes reduces the land required for dumping these wastes. As the earth-based clay material resulted in resource depletion and environmental degradation, so we are making rehash brick which can be replaced for earth clay bricks. Another main objective is to reduce the air pollution caused due to processing of toxic material. The methodology of this project is to use construction and demolition waste as fine aggregate by grinding and sieving the material. Plastic waste is shredded and dissolved by using a solvent. For binding of materials lime, cement and an admixture are used. The mortar is casted in a brick mould and kept for curing for a certain period. The required tests are done for the bricks and it is open to market. The outcome of the project is to reduce the land, air, water pollution and to produce an eco-friendly brick. This brick is cost efficient and can be used for various applications such as in filled wall panels, partition walls and compound walls. Acoustics and waterproof properties are also inculcated into this brick. As a whole this brick acts as a thermal insulator and a replacement for earth clay bricks. [ABSTRACT FROM AUTHOR]

The increase in construction density and disproportionate development in recent years of Moscow spurred the development of urban heat islands (UHI) and urban pollution islands (UPI). The impact of air pollution by hazardous substances from industries, transport, and utilities is currently the most dangerous form of natural environmental degradation in Moscow. Human activities inside the city cause urban pollution and heat gain on the urban surface layer. Since UHI and UPI can interact, exploring the synergism between urban heat and pollution is critical. This paper conducts a systematic review of the existing knowledge on the link between urban heat island (UHI) and urban pollution island (UPI). The results of determining the urban pollution island of Moscow by remote sensing image analysis are presented. The research results will contribute to developing an urban environmental assessment methodology based on the relationship of UHI and UPI and propose optimal solutions to reduce urban heat island (UHI) and urban pollution island (UPI) to improve the living environment within the city. The plan to develop a smart city should be focused on green space inside the city, playing a vital role in minimizing dust dispersion, contributing to air pollution reduction, and playing an active role in reducing urban surface temperature.

Impact of aircraft on the atmosphere studied specifically their effect as a source of air and water pollution and how they contribute to the transmission or spread of diseases such as Covid 19. Aircraft engines generate various gases like carbon dioxide (CO2), including around 70% of the exhaust, and water vapor (H2O), which provides about 30%. Lower than 1% of this exhaust is consists of pollutants such as oxides of nitrogen (NOx), sulfur oxides (SOx), monoxide of carbon (CO), and especially combusted or unburned hydrocarbons (HC), particulate matter (PM), and other components. In addition, many pollutants formed in combustion convert when they are emitted into the atmosphere. All these emissions are a significant source that contributes to environmental pollution. Also, in our current days, we notice the spread of Coronavirus significantly with the increasing cases of travel and movement between governorates and countries, which makes transportation in general one of the causes of its spread as this virus travels through the air and thus affects human health in a very negative way. Statistical analysis of the impact of aircraft on air and water pollution and the problems of COVID 19 have been investigated. With the rapid development of equipment and technologies used in airplanes, and therefore current-days, airport transmission has been widespread attention with a focus on social and economic well-being, environmental activity, and protection towards sustainability.
