“…In reality, this occupation is concentrated in the unloading of materials and the loading of raw materials into the production area, three to four times a day for short periods of time. The same reasoning applies to PM 10 , PM 2.5 , and CO 2 in the office [8,19].…”

“…The chemical composition of the particles is determined by the emission process, which is caused by the different possibilities of chemical combinations [7]. These particles are PM 10 (i.e., particles up to 10 µm in aerodynamic equivalent diameter), coarse particles or PM 2.5-10 (particles between 2.5 and 10 µm in aerodynamic equivalent diameter), and PM 2.5 or fine particles (particles up to 2.5 µm in aerodynamic equivalent diameter) [8].…”

The primary sources of ultrafine particulate matter are linked to human activity. Certain particulate emissions, particularly those of a finer nature, can significantly impact human health, making them one of the most concerning pollutants. Ultrafine particles (UFPs), which have a diameter of less than 100 nm, are of particular concern due to their impact on human health and the difficulty in controlling them. The concentration of ultrafine particles (UFPs) in the workplace is a growing concern and is classified as an emerging risk. Workers may be exposed to UFPs through inhalation, skin absorption, ingestion, or a combination of these routes. This study aims to determine the levels of UFP exposure among workers in environments with varying direct particle emission patterns. Measurements were conducted to compare the results with the levels recommended by the WHO. The study monitored industrial workplaces with direct particulate matter emissions, such as a carpentry workshop and a bakery, as well as social sector sites without or almost without direct particle emissions, such as a school and a health clinic. One conclusion drawn from this study is that all tasks and occupations are susceptible to high levels of UFPs, exceeding WHO recommended values in virtually all monitored environments. Therefore, monitoring and controlling UFPs is crucial. Further in-depth studies on this subject are also necessary.

“…Finally, the correlation between PM10 concentration and the air temperature was negative. Others have reached the same conclusion [36,60,61,65,66]. However, the strength of the correlation varied across the city from −0.107 (TIM-235) to −0.635 (TIM-0C2).…”

“…While our list is not exhaustive, it aims to highlight citizens' interest in ambient air quality, a context with which the uRADMonitor ® network is fully aligned. Other initiatives and studies have also documented using low-cost sensors to monitor particulate matter finer than PM10 and PM2.5 [35,36].…”

A Community-Based Sensor Network for Monitoring the Air Quality in Urban Romania

Air quality, especially particulate matter pollution levels in urban areas, is an essential academic and social topic due to its association with health issues and climate change. In Romania, an increasing awareness of urban communities and the availability of low-cost sensors has led to the development of an independent monitoring network currently distributed in over 194 cities and towns. The uRADMonitor® network consists of 630 sensors measuring PM10 and PM2.5 concentration levels. The spatial distribution of the sensors complements the national air quality network with sensors in residential areas, intense traffic zones, and industrial areas. The data are available through a user-friendly web-based platform from uRADMonitor®. Based on data collected in 2021, we present an analysis of PM10 pollution levels in Romania’s five most populated urban areas by employing five annual statistical indicators recommended by the European Environmental Agency. For the case of Timișoara, we also compare the data measured by independent sensors with those from the national monitoring network. The results highlight the usefulness of our community-based network as it complements the national one.

“…Additionally, particles with aerodynamic diameters up to 2.5 µm are termed fine particle matter (PM 2.5 ). Ultrafine particles with a diameter below 1 micron are called PM 1.0 [1][2][3]. Both anthropogenic (man-made) and natural PM are known [2,3].…”

This study evaluates low-cost sensors (LCSs) for measuring coarse and fine particulate matter (PM) to clarify and measure air pollution. LCSs monitored PM10, PM2.5 (fine particulates), and PM1.0 concentrations at four sites in Samutprakarn, Thailand from December 2021 to April 2022. Average daily PM10, PM2.5, and PM1.0 concentrations at the monitoring locations were 53–79, 34–45, and 31–43 μg/m3, respectively. In December 2021, the monitoring station had a daily PM2.5 value above 100 μg/m3, indicating haze occurrences. However, the monitoring site’s daily PM10 and PM1.0 concentrations did not surpass Thailand’s ambient air quality threshold. We also measured and calibrated comparative particulate matter concentrations from LCSs and a tapered element oscillating microbalance (TEOM) monitor (Pollution Control Department (PCD) standard analytical method). PM2.5 concentrations from the LCSs were lower than TEOM, but the difference was not statistically significant. The PM2.5 monitoring station provided near-real-time air quality data for health risk reduction, especially when PM levels were high. Based on this study, authorities and local agencies may consider improving air quality regulation in Samutprakan, focusing on suburban PM2.5 air pollution.
