Abstract
The air quality of modern cities is considered an important factor for the quality of life of humans and therefore is being safeguarded by various international organizations, concentrating on the mass concentration of particulate matter (PM) with an aerodynamic diameter less than 10, 2.5 and 1 μm. However, the different physical and anthropogenic processes and activities within the city contribute to the rise of fine (<1 μm) and coarse (>1 μm) particles, directly impacting human health and the environment. In order to monitor certain natural and anthropogenic events, suspecting their significant contribution to PM concentrations, seven different events taking place on the coastal front of the city of Limassol (Cyprus) were on-site monitored using a portable PM instrument; these included both natural (e.g., dust event) and anthropogenic (e.g., cement factory, meat festival, tall building construction, tire factory, traffic jam, dust road) emissions taking place in spring and summer periods. The violations of the limits that were noticed were attributed mainly to the various anthropogenic activities taking place on-site, revealing once more the need for further research and continuous monitoring of air quality.
Highlights
Air pollution is considered an increasingly important environmental issue with direct implications on human health, ecology and climate [1,2,3,4]
Various sources are responsible for the presence of a variety of air pollutants such as NOx, CO2, SOx, O3, volatile organic compounds (VOCs), polyaromatic hydrocarbons (PAHs) and particulate matter (PM)
Air pollution by PMs is considered among the most important risk factors associated with premature mortality from cardiovascular, respiratory diseases and lung cancer [2,3,5,6,7]; it affects even COVID-19 mortality contributing to a 15% worldwide increase, while this percentage in Europe amounts to 19% and in neighbouring Greece 9% [8]
Summary
Air pollution is considered an increasingly important environmental issue with direct implications on human health, ecology and climate [1,2,3,4]. Various sources are responsible for the presence of a variety of air pollutants such as NOx , CO2 , SOx , O3 , volatile organic compounds (VOCs), polyaromatic hydrocarbons (PAHs) and particulate matter (PM). These important air pollution components are globally recognized and widely monitored [5]. In the EU-28, the levels of environmental concentrations are regulated by Directive
