Antilope: A low-cost portable sensor system for air quality monitoring

Antilope is a low-cost portable sensor system for air quality monitoring

Monitoring air quality and assessing personal pollutant exposure in urban settings remain challenging tasks in atmospheric science. As part of this monitoring, low-cost sensors have become increasingly available. This allows makers to assemble their own air quality stations according to online instructions, and institutions to multiply the number of measurement points. However, most of these commercial devices suffer from limitations […]

License-plate-based driving restrictions: Do they really backfire?

Written by

Dr Erick Guerra undertakes a literature review of the effects of license-plate-based restrictions in cities on the local air quality, with respect to policymaking and behavioural responses to the policies

Driving restriction policies that limit the number of days drivers can use their vehicles within cities based on the last digit of their license plates are popular in some cities. Research into their effectiveness in reducing air pollution and congestion, however, yields mixed results. Dr Erick Guerra and his colleagues at the University of Pennsylvania, USA, have published the first […]

Monitoring toxic pollutants for better air quality

Written by

Industrial combustion releases flue gas into the air.

Air quality is imperative for our and the environment’s health. Research around air quality has been focusing on the monitoring, testing, and investigation of toxic pollutants, such as heavy metals, polychlorinated and polycyclic aromatic compounds, or particulate matter (PM2.5). Professor Guo-Ping Chang-Chien, director of the Super Micro Mass Research and Technology Center at Cheng Shiu University of Science and Technology […]

Air pollution monitoring and its role in public health

Written by

Air pollution monitoring is an important factor in air quality management. Both established long-term monitoring stations and short-term seasonal atmospheric field measurements are required to understand how atmospheric chemistry changes in response to air pollution regulation. Professor Schwab and his team from the University at Albany maintain long-term rural monitoring stations as well as highly specific mobile air pollution measurements […]
