Spezzano P. Estimates of the economic damage due to the soiling of residential buildings induced by air pollution in Italy. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2022; 29:52336-52354. [PMID: 35257347 DOI: 10.1007/s11356-021-17743-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/04/2021] [Accepted: 11/21/2021] [Indexed: 06/14/2023]
Abstract
The soiling of the external façades of buildings caused by air pollution has economic costs that are generally not borne entirely by the polluters but by society in general. The present paper attempts to estimate the maintenance costs attributable to the soiling of the façades of residential buildings exposed to ambient air pollution in Italy. In this study, dose-response functions were used to link the environmental concentrations of pollutants to the soiling rate of the opaque and transparent surfaces of the building façades. It was assumed that the spatial distribution of façade materials follows the distribution of population. The basic assumption was that maintenance is performed when critical levels, 35% loss of reflectance for opaque surfaces and 1% haze for glass surfaces, are reached. Several important elements seem to emerge from the analysis carried out. The cost of damage to opaque surfaces due to air pollution appears to be a non-negligible fraction of the total maintenance costs of building façades incurred in Italy. Moreover, the cost of soiling damage to residential buildings from particulate matter has the potential to significantly increase total external costs due to air pollution. The costs of cleaning window panes due to air pollution also appear significant. Finally, if the levels of atmospheric pollution in the most populated areas become similar to the concentrations currently present in the most remote areas in Italy, the overall cost at national level due to the soiling of the building façades could be reduced by about 50%.

Abstract
Atmospheric aerosols are today a key issue in air pollution, mostly related to public health. Two test areas in Ferrara, one in the city center (urban location) and one in the industrial area (industrial location), were studied in June–July 2016 using the SEM technique to identify the environmental impact of some potential pollutant sources. Collection was performed using adhesive tapes applied on the surface of road signs, which allows to select particulate matter moving on air with diffusion movement and to exclude the particles usually deposed by the gravitational process. Dimensional characterization has shown that, usually, smaller particles tend to aggregate themselves in bigger polycrystalline particles with the geometric diameter of up to 10 μm. Micro-analytical data have revealed a wide heterogeneous range of compositions: more abundant silicate followed by carbonate, chlorine, sulphate, carbon, and organic. This preliminary study has highlighted that the Renaissance city of Ferrara is affected by an environmental problem linked to the presence of particulate matter induced by industrial activities, as is the case with some of the most polluted cities in the world. The observations and analytical data pointed out the need for further investigation to better define the features of the fine particulate matter. This will be useful to preserve the cultural heritage of this Medieval-Renaissance city.

Abstract
From the 1950s and 1960s of the last century, a parish church dating back to the 6th century AD was identified during reclamation works of Valle Pega. The archaeological investigation allowed the recovery of the parish and the attached baptistery, as well as some tombs closely connected to the church. Following the excavation, it was possible to collect some samples of bricks and mortars in order to identify the different compositions of the materials used for the construction of the parish. All the samples were analyzed through optical microscopy, X-ray powder diffractometric analysis and observation through scanning electron microscope. Thanks to the investigations carried out on the samples, it was possible to hypothesize the different construction phases and the different materials used and to identify the firing temperatures at which the bricks were built.

Background Concentrations of Cultivable, Mesophilic Bacteria and Dust Particles in the Air in Urban, Rural and Mountain Regions. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17249572. [PMID: 33371355 PMCID: PMC7767401 DOI: 10.3390/ijerph17249572] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Revised: 12/08/2020] [Accepted: 12/15/2020] [Indexed: 11/16/2022]
Abstract
Particulate air components can be of anthropogenic or natural origin. It is assumed that in different geographical areas varying concentrations of mesophilic bacteria are present in the ambient air. The aim of this study was to determine the background concentrations of airborne culturable mesophilic bacteria and particulate matter in the ambient air. Furthermore, the association between their concentrations and some environmental factors was analysed. In the period from July to October 2019, concentrations of mesophilic bacteria and dust particles were measured in urban, rural and mountain areas using the single-stage air sampler and the particle counter. The concentrations of bacteria and dust particles in the air were counted as number of Colony Forming Units per cubic metre (CFU/m3) and particles per cubic metre (pa/m3). Staphylococcus sp. were identified. The median values of the cultivated mesophilic bacteria at 30 °C and 37 °C were 7.1 × 102 CFU/m3 and 2.3 × 101 CFU/m3 in mountain regions, 1.3 × 102 CFU/m3 and 6.9 × 101 CFU/m3 in rural regions and 2.1 × 102 CFU/m3 and 6.5 × 101 CFU/m3 in urban regions. The median of Staphylococcus sp. was 2.5 × 100 CFU/m3 in alpine areas and 7.5 × 100 CFU/m3 in urban and rural areas. Higher bacterial concentrations were measured in sunshine and in windy weather. A relationship was observed between the concentrations of airborne mesophilic bacteria and the coarse particles in all three areas. The present study determined values between 5.0 × 100 and 4.6 × 102 CFU/m3 as natural background concentrations of airborne mesophilic bacteria and 1.2 × 107 pa/m3 and 6.5 × 104 pa/m3 for fine and coarse particles, respectively. These results can be proposed as baseline for the assessment of the emission sources of mesophilic bacteria for summer and early autumn.

Medieval Glassworks in the City of Ferrara (North Eastern Italy): The Case Study of Piazza Municipale. HERITAGE 2020.

Abstract
Compositional and structural characterization was carried out on transparent glass fragments found in a brick rubbish pit discovered in basal floor of the ducal palace of Ferrara, during the excavation of Piazza Municipale. This study aims to identify raw materials and glass-working techniques through X-Ray Fluorescence (XRF) quantitative chemical analyses and semi-quantitative Scanning Electron Microscopy (SEM) observations. The studied fragments were produced using siliceous-lime sands with natron as flux, and allowed us to better understand the production technologies in a historical period of great innovation for European glass art. The numerous findings of glass fragments discovered in brick underground cellars built for the specific purpose of household rubbish of wealthy complexes in Ferrara testify a consolidated system of separate discharge of solid waste into underground containers, which were closed and sealed once filled. The high volume of the finds indicates the absence of recycling of accumulated materials due to the well-being of the city. Compositional analysis confirmed the local production of glass shops in Ferrara during the late Middle Ages, characterized by differences with the glasses of the nearby city of Venice. Morphological analyses also defined the nature and relative abundance of the products, exploring the types and compositions of the Ferrara glass art.

Orange Snow—A Saharan Dust Intrusion over Romania During Winter Conditions. REMOTE SENSING 2019. [DOI: 10.3390/rs11212466] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 01/29/2023]
Abstract
On the morning of 23 March 2018, an unusual phenomenon was observed over Romania where the southeastern part of the country was covered in a fresh-layer of orange snow. The event was extensively reported in mass-media and social-media and raised questions about the origin and the possible impact of the orange snow. Even if this type of events, intrusions of Saharan dust, have been reported before in Romania, and in Europe in general, their occurrence during negative temperature conditions is very rare. Saharan dust intrusion occurs over Europe mainly during spring and, in general, is not accompanied by snow at low altitudes. In this article, for the first time, the synoptic-scale conditions leading to the Saharan dust intrusion over Romania and the chemical and physical properties of the deposited dust particles in a snow layer were analyzed. The Saharan dust event affected a permanent atmospheric measurement research infrastructure located southwest of Bucharest, the capital city of Romania. In-situ and remote sensing measurements conducted at this research infrastructure allowed the identification of the dust source as the north Sahara. The source was confirmed by the elemental ratios of the main components (e.g., Al, Ca, Mg, Fe, K). For example, the (Ca+Mg)/Fe ratio of 1.39 was characteristic for the north Sahara. The dust morphology and the minerals were analyzed by scanning electron microscopy with energy disperse X-ray spectrometry (SEM/EDX). The size distribution of the particle geometric diameter showed that they are centred on 1 μ m, but larger particles up to 40 μ m are also present. To visualize the minerals, an approach was developed which emphasized the presence of the calcite, quartz or clay minerals. The optical parameters of dust were measured by re-suspending the particles. Values of the optical parameters (i.e., asymmetry parameter at 550 nm was 0.604, single scattering albedo was 0.84–0.89) were similar to those measured for Saharan dust intrusions over the Iberian Peninsula. Also, the non-refractory particles found in the dust-contaminated snow layer were analyzed, indicating the presence of HULIS-like compounds, most probably advected from the Mediterranean sea.
