Optical monitors have proven their versatility into the studies of air quality in the workplace and indoor environments. The current study aimed to perform a screening of the indoor environment regarding the presence of various fractions of particulate matter (PM) and the specific thermal microclimate in a classroom occupied with students in March 2019 (before COVID-19 pandemic) and in March 2021 (during pandemic) at Valahia University Campus, Targoviste, Romania. The objectives were to assess the potential exposure of students and academic personnel to PM and to observe the performances of various sensors and monitors (particle counter, PM monitors, and indoor microclimate sensors). PM1 ranged between 29 and 41 μg m−3 and PM10 ranged between 30 and 42 μg m−3. It was observed that the particles belonged mostly to fine and submicrometric fractions in acceptable thermal environments according to the PPD and PMV indices. The particle counter recorded preponderantly 0.3, 0.5, and 1.0 micron categories. The average acute dose rate was estimated as 6.58 × 10−4 mg/kg-day (CV = 14.3%) for the 20–40 years range. Wearing masks may influence the indoor microclimate and PM levels but additional experiments should be performed at a finer scale.

Great Focus

Noise is commonly known to have adverse health effects on residents in urban living environment. In the past, great focus has been placed on the impact of external traffic noise on residents’ health and the development of urban noise mapping. On the other hand, neighbourhood noise − a combination of noise generated from outside residences and noise generated from within residences − are also considered to be as detrimental as external traffic noise and are yet to be widely investigated. This paper focuses on the systematic review of studies assessing neighbourhood noise with the intention of determining the presence of architectural variables and methods of noise representation for micro-scale areas. 153 articles are retrieved from specific research databases and out of which 12 were considered to be relevant to the study. The results indicate that architectural variables present in the studies were mostly related to the analysis of external traffic noise and that representation of noise in analyses were rarely devised which highlights the need for further investigation in this area.

Acoustic Comfort

Negative noise influence to the population health is increasing every year. Italian and Russian approaches to noise influence estimation are described. Acoustic comfort in urban areas cannot be completely separated by other factors influencing the quality of life. Results of estimation of noise influence are presented. Modeling of noise propagation and noise mapping in Russia are considered. Formalization and modeling of transport flows it is suggested to do by using of influence diagrams. Example of transport noise estimation in Italy is described.

Comprehensive Picture

The Hydraulic Laboratory of Liège University, Belgium, is historically considered from its foundation in 1937 to the mid-1960s. The technical facilities of the various Buildings are highlighted, along with canals and instrumentation available. It is noted that in its initial era, comparatively few basic research has been conducted, mainly due to the professional background of the professors leading the establishment. This state was improved in the past 50 years, however, particularly since the Laboratory was dislocated to its current position in the novel University Campus. Biographies of the leading persons associated with the Liège Hydraulic Laboratory are also presented, so that a comprehensive picture is given of one of the currently leading hydraulic Laboratories of Europe.
