Low-cost electrochemical sensors and in-house developed data acquisition system are used in two experiments, which
reflect real-life scenarios of air pollution. Primary aim of this research is evaluation of the new approach for measuring
the concentrations of toxic gases in realistic, everyday situations. These experiments include: continuous diurn...

... the same location of the technical inspection station of the vehicle there is also a ventilation system that plays a significant role in the non-working hours as will be seen on the results shown below. The view on the vehicle technical inspection station, as well as the position of the device with the specified Alphasense sensors, are shown in the Figure 1. The Air Quality Measurement Device with the specified sensors by Alphasense is positioned at the middle of the vehicle's technical inspection station, next to the MAHA Exhaust Gas Analyser. ...

... Our drone platform was developed in-house, based on Ardupilot open-source autopilot and commercially available electronic components [16]. This platform has a modular design and can carry various sensors and equipment, including electrochemical sensors for toxic gases [17], [18], and the abovementioned PM sensors. In our previous work we discussed quality assurance (QA) procedures that were applied to ensure reliable data [19], [20]. ...
A novel method for terrain mapping is presented in this paper. It is based on low-cost open source components, which brings this innovative technique to a much wider group of researchers than ever before. The in-house developed drone was used together with a commercially available LiDAR sensor to produce a terrain mapping platform. This system was tested in two field locations with good results. In some aspects of performance, the drone surpassed commercially available solutions that are much more expensive and closed.

Nanoparticles with diameters from 10 nm to 1000 nm were analyzed using the scanning mobility particle sizer (SMPS) continuously from October 2020 till May 2021. Mass spectrometry was performed in 129 channels. Measurements of some other air pollution parameters were used for comparison and analysis. A large number of nanoparticles was detected in the period of strong air pollution, as expected. However, a surprisingly large number of nanoparticles was detected in spring and summer, where other parameters of air pollution were good.
Keywords: SMPS; nanoparticles; air pollution; mass spectrometry.
To provide the reference dataset for particulate matter concentrations, a long-term campaign of continuous gravimetric measurements of PM10 and PM2.5 concentrations was performed. Strict implementation of standard EN12341:2014 was fulfilled. Daily and monthly concentrations of both PM10 and PM2.5 were measured with the highest possible accuracy. Ratio PM2.5/PM10 was determined and analyzed. Different distribution of particles was observed during the winter period, where most of the particulate matter originates from burning fossil fuel, and during an episode of Sahara dust, occasionally observed in spring and summer.
Keywords: PM10; PM2.5; gravimetric measurement; Sahara dust.
A new method for mobile measurements of black carbon (BC) concentration measurements is presented in this paper. An advanced pocket-sized aethalometer with 5 wavelengths and dual-spot technology was used. Different measurement locations were selected to evaluate the contribution of car emissions and biomass burning emissions during the winter campaign in heavily polluted urban environments. A model based on the Angstrom exponent is proposed for source apportionment studies. Obtained results confirmed the system's capability to distinguish BC sources with high temporal and spatial resolution.
A novel method for indoor air quality monitoring is presented in this paper. It is based on the network of smart sensors permanently connected to the cloud. The prototype system, consisting of 10 smart sensors is evaluated in laboratory and real use. Each smart sensor was able to measure air temperature, relative humidity, particulate matter concentration, and carbon dioxide concentration. The cloud-based architecture of the system is explained, followed by the calibration method and real scenario results. The system proved to be suitable for real-time monitoring of indoor air quality parameters for large buildings.
