Air pollution monitoring: a solution for cost effective measurements - Case study
Air pollution is one of the main environmental problems to be addressed by cities worldwide. In order to foster sustainable development and mitigate climate change, it is therefore important to provide national and regional authorities with appropriate measures to reduce criteria pollutants (PM 10, PM2.5, O3, CO, SO2 and NOx) concentrations in ambient air. Many cities are not able of meeting ...

Passive vs Active Sampling for Sensor-based Ambient Air Quality Monitoring
Air pollution with its cascading effects across the population has become a serious matter of concern. To address this air pollution problem, availability of accurate and reliable air quality data is crucial. The quality of air monitoring depends upon how the sample of air is collected and how it is analysed. This paper majorly focuses on passive vs active sampling for air quality monitoring. ...

Air pollution overtakes AIDS related deaths
Research findings show that annual PM2.5 concentrations in some African cities are as much as 5 times over the WHO limit for health-harmful concentration. Findings like these place air pollution as the leading cause of premature death in Africa, overtaking AIDs related deaths. The research is highlighted by the Columbia Earth Institute The studies were carried out in 2018/19 in Kinshasa, ...

EPA establishes new 1-hour standard for sulfur dioxide
On June 2, 2010, the U.S. EPA established a new 1-hour primary National Ambient Air Quality Standard (NAAQS) for sulfur dioxide (SO2). The new 1-hour standard was set at the level of 75 parts per billion (ppb) calculated as the three-year average of the 99th percentile of the annual distribution of daily maximum 1-hour average concentrations. With the establishment of the new 1-hour SO2 standard, ...
