The association between air pollution and lung cancer in the north west of Adelaide: a case control study and air quality monitoring.
… lung cancer in NW Adelaide. Contemporary ambient air monitoring was undertaken as an indicator of future respiratory health risk. 142 lung cancer patients and 415 age, gender matched population controls were interviewed utilising an event history calendar. Lifetime exposure indices were calculated …

CMB7 receptor modelling of airborne particulate matter in the Vaal Triangle
The primary aim of the Vaal Air Monitoring (YAM) programme was to do a one year source apportionment study of airborne particulate matter in the Vaal Triangle. The V AM programme was undertaken by Mintek, in South Africa. Three receptor sites were set up, oneea.ch in the Central Business District …

A breath of fresh air the use of geographic information systems for the sustainable management of air quality in Malta
… human health and environmental issues related to air quality requires the EU member states to monitor a range of air pollutants and fall in line with limit values. For this reason two air monitoring systems have been set up in the Maltese Islands. These are run by Malta Environment and Planning …

Bayesian spatio-temporal modelling for forecasting ground level ozone concentration levels
… instantaneous and high resolution spatial air-quality information can better inform the public and regulatory agencies of the air pollution levels that could cause adverse health effects. The most direct way to obtain accurate air quality information is from measurements made at surface …

Examining the Association of Environmental Degradation and Poor Cardiovascular and/or Respiratory Health Outcomes in a Disadvantaged Community
<p>Air pollution is associated with poor cardiovascular and/or respiratory health outcomes. The poor air quality in certain communities due to the emission of toxic air pollutants from industries and major roadways has been a growing concern. The main objective of this study was to examine whether …

A method for correlation of gravestone weathering and air quality (SO2), West Midlands, UK
… the 1970s Britain suffered the effects of poor air quality primarily from particulate matter and acid in the form of NOx and SOx compounds. Air quality stations across the region recorded SO2 beginning in the 1960s however the direct measurement of air quality prior to 1960 is lacking and only …

Bridge to digital converters for environmental monitoring in edge IoT devices
Continuous air monitoring is crucial for maintaining safe and comfortable home and work environments, particularly in industries that handle flammable or toxic gases, which pose serious health risks. Consequently, there is an increasing focus on developing wearable gas sensors to protect workers in …
