Background & Aims of the Study: Among different kinds of air pollutants, Particle matters due to their proved destructive impacts on human health and their various sources like transportation attract wide attention. The objective of this work is determining the real value of particle matters in one of the important and busy roads in Iran (Sari- Qaemshahr ro...
Air pollution has been an vital issue throughout the 21st century, and also significantly impacted agricultural community, especially farmers yield crops. This work aims to review air-pollution research understand its impacts on community crops, specifically in developing countries, such as India. The present highlights various aspects of damage caused by air pollution. Furthermore, undertaken ...
The lockdown policy, resulted from the fight against spread of Covid-19, offers a unique chance to test effect urban human activities on air quality. study employs event method analyze data quality (particulate matter 2.5 (PM2.5) and Air Quality Index (AQI)) levels economic activity (vehicle sales growth, construction area, industrial added value, crude oil production) 31 major cities across Ch...
Satellite remote sensing is of considerable importance for estimating ground-level PM2.5 concentrations to support environmental agencies monitoring air quality. However, most current studies have focused mainly on the application of MODIS aerosol optical depth (AOD) to predict PM2.5 concentrations, while PARASOL AOD, which is sensitive to fine-mode aerosols over land surfaces, has received lit...
The present study deals with the quantitative effect of vehicular emission on ambient air quality during May 2006 in urban area of Lucknow city. In this study SPM, RSPM, SO2, NOx and 7 trace metals associated with RSPM were estimated at 10 representative locations in urban area and one village area for control. Beside this, air quality index (AQI), health effects of different metals and mortali...

background: since the industrial revolution, the rate of industrialization and urbanization has increased dramatically. regarding this issue, specific regions mostly located in developing countries have been confronted with serious problems, particularly environmental problems among which air pollution is of high importance. methods: eleven parameters, including co, so 2 , pm 10 , pm 2.5 , o 3 ...
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...
Air pollution primarily originates from substances that are directly emitted natural or anthropogenic processes, such as carbon monoxide (CO) gas in vehicle exhaust sulfur dioxide (SO2) released factories. However, a major air problem is particulate matter (PM), which an adverse effect of wildfires and open burning. Application tools for monitoring risk areas using real-time with drones have em...
