The city of Tehran undergoes an increasing growth in population as well as industrial activities, both of which increase the concentration of air pollutants. The current research tries to turn a limited and focused system of air contamination measurement and control to an unlimited and extensive one that examines the concentration of each of the contaminants in any area of Tehran. Accordingly, ...

Asthma is one of the most common diseases in childhood, which has been increased during last decade because of epidemiological pattern changes with climate and industrialization of the communities. There are some controversies on the relationship between air pollution and asthma. Tehran, as the capital of Iran, is one of the densest populations and is one of the most polluted cities in the worl...

Abstract The purpose of this study is to determine and analyze several variables that affect the Air Quality Index (AQI) in Indonesia 2012 – 2019. data used secondary form panel related AQI, circular economy, digital economy 34 provinces period were retrieved from Ministry Environment Forestry (KLHK), Central Statistics Agency (BPS) Provincial Sanitation Office (DKK) Indonesia. analytical tool ...

Identifying the particulate matter (PM) sources is an essential step to assess PM effects on human health and understand PM’s behavior in a specific environment. Information about composition of organic or/and inorganic fraction usually used for source apportionment studies. In this study that took place Dakar, Senegal, identification two fractions was performed by utilizing data elemental carb...

Air Quality Index (AQI) is an indicator of the pollution level our surroundings and household. Prediction AQI values from historical can help us analyze mitigate levels. The be classified into predetermined categories machine learning algorithms made use to improve classification accuracy value calculated. main objective paper provide potential researchers, with importance various Machine Learn...

Health impact assessment has become important in the development of air quality policies and in finding the relationships between pollutants concentration and health effects. In our work we presented a novel index able to evaluate the effects on the human exposure caused by ambient air pollution in urban areas. The index is able to link both health risk factors and pollutants levels. The indexe...

The diameter of PM2.5 is less than that 2.5 μg/m3 particulate matter; small enough to enter the body through alveolar microvasculature and has a major impact on human health. Therefore, people are interested in establishment air quality monitoring forecasting. historical current indices (AQI) can now be easily obtained from sensors. However, more likely need forecasting information. Based liter...

The Carbon trading price (CTP) can best reflect the fluctuations of carbon market. This paper comprehensively analyzes CTP mechanism China’s market, discusses main factors affecting CTP, which include macroeconomic factors, energy policy and environmental provides three hypotheses. In order to highlight test hypotheses about five representative pilot markets were included: Beijing, Shenzhen, Sh...
