A Study on Outdoor and Indoor Climate to satisfy particular Requisites in Museum. The case of the Punic Ship in the Marsala's Archaeological Museum

2003

In the Archaeological Museum in Marsala are keept many archaeological finds discovered in the sea near the city. The most important is the wooden hull of an ancient punic ship found some years ago. The rests of the ship have been submitted to impregnation with PEG, to eliminate the water and the salts absorbed the sea mud, and then is exposed inside a protective awning of plastic material, build up in one of the rooms, in order to contain as much as possible the indoor climatic variations. The responsibles of the museum wants now expose the finds in an free environment in which fixed and steady conditions can be kept. The authors have been requested to study an air condition system that can…

Il comfort indoor nel patrimonio edilizio esistente. Tecnologie e metodi per gli ambienti di vita

2022

This volume is the result of wide-scope research on the application of IEQ (Indoor Environmental Quality) in existing buildings. The examined items are the evaluation methods and standards related to the environmental parameters for the well-being levels required to guarantee suitable livability in indoor environments. An analysis is provided on the state of the art of technological aspects in architecture for the achievement of salubrious and comfortable indoor spaces. The study is focused on passive systems for microclimatic control, with a re-proposition of the most ancient ones. Nowadays, when revisited, they have proven to be effective solutions, especially due to their possibility to …

Indoor air quality in schools of a highly polluted south Mediterranean area

2019

This study aimed at surveying lower secondary schools in southern Italy, in a highly polluted area. A community close to an industrial area and three villages in rural areas was investigated. Indoor temperature, relative humidity (RH), gaseous pollutants (CO 2 and NO 2 ), selected biological pollutants in indoor dust, and the indoor/outdoor mass concentration and elemental composition of PM 2.5 were ascertained. Temperature and RH were within, or close to, the comfort range, while CO 2 frequently exceeded the threshold of 1000 ppm, indicating inadequate air exchange rate. In all the classrooms, median NO 2 levels were above the WHO threshold value. Dermatophagoides p. allergen concentration…

Emergence of Aspergillus fumigatus azole resistance in azole-naïve patients with chronic obstructive pulmonary disease and their homes.

2017

Azole-resistant Aspergillus fumigatus (ARAF) has been reported in patients with chronic obstructive pulmonary disease (COPD) but has not been specifically assessed so far. Here, we evaluated ARAF prevalence in azole-naïve COPD patients and their homes, and assessed whether CYP51A mutations were similar in clinical and environmental reservoirs. Sixty respiratory samples from 41 COPD patients with acute exacerbation and environmental samples from 36 of these patient's homes were prospectively collected. A. fumigatus was detected in respiratory samples from 11 of 41 patients (27%) and in 15 of 36 domiciles (42%). Cyp51A sequencing and selection on itraconazole medium of clinical (n = 68) and e…

Occupational hygiene in a waste incineration plant

2003

Abstract The Turku incineration plant was renovated in 1995 to meet the emission requirements of modern waste combustion facilities. It treats presorted municipal waste from 170,000 residents in the Turku area. In the plant, the incineration process produces several types of by-products having importance in terms of occupational hygiene. Although not obligated by the law, the management of the plant has a keen interest in occupational hygiene at the plant, which was studied from 1998 to 2001. Concentrations of microbes, endotoxins, and dust and the noise level were investigated in three different working areas. Microbe measurements were conducted with a six-stage impactor and using the CAMN…

A comparative study on the quality of air in offices and homes.

2013

The main purpose of this study was to collect data on some of the factors that contribute to indoor air quality and to discomfort, in order to take the proper actions that can reduce the level of air pollution within houses and offices. To ascertain the contamination degree total bacterial counts, total fungal counts, suspended particulate matter, air temperature, and relative humidity have been determined. Additionally, mathematical statistical models have been elaborated for the total bacterial count, respirable particulate matter and humidity. A total number of 40 indoor air samples were collected from office and houses. The results shows that approximately 45% of the air samples from ho…

The distribution of phthalate esters in indoor dust of Palermo (Italy).

2013

In this work, phthalic acid esters (PAEs): dimethyl phthalate (DMP), diethyl phthalate (DEP), di-n-butyl phthalate, benzyl butyl phthalate, bis(2-ethylhexyl) phthalate, and di-n-octyl phthalate in indoor dust (used as passive sampler) were investigated. The settled dust samples were collected from thirteen indoor environments from Palermo city. A fast and simple method using Soxhlet and GC–MS analysis has been optimized to identify and quantify the phthalates. Total phthalates concentrations in indoor dusts ranged from 269 to 4,831 mg/kg d.w. (d.w. = dry weight). The data show a linear correlation between total PAEs concentration and a single compound content, with the exclusion of the two …

Assessing the effectiveness of green roofs in enhancing the energy and indoor comfort resilience of urban buildings to climate change: Methodology pr…

2021

Abstract The effects of climate change on the built environment represents an important research challenge. Today, green roofs (GRs) represent a viable solution for enhancing energy and urban resilience in the face of climate change, as they can have a positive impact on the building's indoor thermal comfort and energy demand, as well as inducing various environmental benefits (easing urban heat island effects, improving the management of runoff water, reducing air pollution, etc.). Thus, it is important to be able to assess their effectiveness, both today and under future climate conditions, in order to evaluate whether they can also provide a valid long-term solution. In this paper, a sim…

Indoor and outdoor determination of pesticides in air by ion mobility spectrometry.

2016

Abstract The use of ion mobility spectrometry (IMS) has been evaluated as analytical methodology to detect and evaluate the occupational exposure to pesticides. The developed IMS methodology was used, in positive and negative modes, to determine the presence of pesticides in air and to evaluate possible inhalation exposures of workers and users based on active sampling on Teflon membranes and direct thermal desorption IMS. The negative IMS mode was used to determine bensulfuron, clorpyrifos, diniconazole, diuron, flutolanil and imidacloprid, while the positive mode was employed to evaluate formetanate, metalaxyl, metamitrone, metribuzin, paclobutrazol and pirimicarb. The IMS measurements pr…
