Thermo-hygrometry and IAQ Related Measurements of the Indoor Physical Conditions of Exhibition Halls for Complying International Rules and Standards
2018
Off-line methods for detecting the indoor physical parameters of museums are important tools in order of continuously monitoring the conditions at which works of art are exposed. These conditions, in fact, are mandatory established by several rules and technical standards aimed at preserving the specific artifacts. Moreover, indoor microclimate parameters must also take into account the comfort conditions for visiting people. Both the above-cited requirements suggest to perform the indoor monitoring with equipment visually low impacting. In this paper, some examples of visually low impacting off-line monitoring methods, applied to three artifacts displayed in the “Museo Regionale” of Palerm…

Determination of indoor air quality of a phytosanitary plant.
2011
A new methodology has been developed to determine volatile organic compounds (VOCs) and pesticides in ambient air using membrane based devices as passive samplers. Pesticides were determined by gas chromatography with mass spectrometry detection (GC-MS) after their microwave-assisted extraction (MAE) from the passive sampler and the required clean-up. On the other hand, VOCs were also caught with the same samplers and directly determined by head space (HS) coupled to GC-MS. The use of samplers filled with florisil and activated carbon allows us to catch with a simple device both, VOCs and pesticides, with a high vapor pressure. Results obtained in the deployment of samplers in different sit…
Students' school‐level symptoms mediate the relationship between a school's observed moisture problems and students’ subjective perceptions of indoor…

Moisture damage can influence the subjective assessment of indoor air quality (subjective IAQ) in various ways. We studied whether the frequency of symptoms reported across students at school level mediates the relationship between observed mold and dampness in a school building and students' subjective IAQ. To answer this research question, we tested a multilevel path model. The analyzed data were created by merging two nationwide data sets: (a) survey data from students, including information on subjective IAQ (N = 24,786 students); (b) data from schools, including information on mold and dampness in a school building (N = 222). After the background variables were adjusted, schools' obser…

A CASE STUDY OF THE INDOOR AIR QUALITY IN SCHOOLS BELONGING TO AN AREA OF THE SICILIAN ISLAND INTERESTED BY THE PRESENCE OF PETROCHEMICAL REFINERIES
2021
The indoor environmental quality is a topic particularly relevant for schools; this category of confined environments is, indeed, occupied by subjects (i.e. children), which are thought to be more vulnerable than adults to the negative health effects of poor indoor air quality, and whose learning process has long been recognized to be influenced by the quality of the indoor environment. This paper presents results of a study concerning the inside air quality of schools in four small towns sited in the southern part of Sicily, interested by the presence of a petrochemical refinery in the surrounding territory. The performed analysis made it possible to highlight the main criticalities regard…
Dampness and student-reported social climate: two multilevel mediation models.
2021
Background Little previous research has analysed the relationship between schools' indoor air problems and schools' social climate. In this study, we analysed a) whether observed mould and dampness in a school building relates to students' perceptions of school climate (i.e. teacher-student relationships and class spirit) and b) whether reported subjective indoor air quality (IAQ) at the school level mediates this relationship. Methods The data analysed was created by merging two nationwide data sets: survey data from students, including information on subjective IAQ (N = 25,101 students), and data from schools, including information on mould and dampness in school buildings (N = 222).
