“…[1][2][3] Several recent publications have reported changes in air composition following cleaning surfaces. Chlorinated species emitted and formed during the use of sodium hypochlorite bleach ("bleach") 4,5 and volatile organic compounds (VOCs) emitted during the use of plant-based (thymol and terpene) cleaners 3,6 can cause irritation and harm to skin and to the respiratory system. 7,8 Hydrogen peroxide (H 2 O 2 )-based cleaners are an alternative to bleach and have gained popularity in times of COVID-19 for being powerful oxidants and effective at deactivating SARS-CoV-2 on surfaces.…”

“…Since people spend a lot of their time indoors, most of the intake takes place there, even when considering outdoor pollution. Several studies have documented the burden of indoor air pollution on occupant health (Mainka and Fantke 2022;Karr et al 2021;Ali et al 2021;Smith and Mehta 2003;Bardana 2001). The presence of several of these substances can be influenced by the building's design.…”

Pollutants – gases or particles – are emitted in indoor air by different sources such as building materials, furniture, occupants and their activities. Spending over 80 % of our time indoors, we are directly exposed to substances that are potentially harmful to our health. Through measurements and simulation tools, the concentrations of these substances in air can be evaluated. However, today, Indoor Air Quality (IAQ) is not taken into account in the Life Cycle Assessment of buildings (LCA). The aim of this study is to calculate and compare the damage of IAQ on occupants’ health with the damage over the whole building life cycle, expressed in the same unit as in LCA: Disability-Adjusted Life Years (DALY), in order to propose a decision-making tool. Volatile organic compounds (VOCs) are emitted by building materials or furniture and then are assimilated by occupants. A model describing their emissions including unknown or uncertain parameters is calibrated using existing emission data. Secondly, emission data on occupants and their activities are used to simulate indoor concentrations of VOCs. The assimilation and consequent health damages are then calculated. According to a case study of an office, health damages related to the emissions of gypsum-covered walls were of 1.32 x 10−6 DALY.year−1, about 2 orders of magnitude lower than those of the other life stages of the building (from fabrication and transport of products, construction, use, until end-of-life processes) which correspond to 1.2 to 4.5 x 10−3 DALY.year−1. Those related to regular office activities were of 3.7 x 10−26 DALY.year−1. This methodology can help in eco-design of buildings by identifying main sources of impacts. It can help to choose between materials or to dimension the ventilation for the evacuation of pollutants.

“…CB has been frequently adopted because risk levels and countermeasures can be easily checked based on the name of the chemical substances handled and the workplace material contents, even without specialized knowledge of the chemical substances. Field measurements in workplace environments are considered an effective method for risk assessment because they provide direct information on actual chemical concentration levels 17,18 . However, these methods cannot flexibly respond to changes in the workplace environment and the exposure risks of chemicals cannot be assessed in advance during the building design stages.…”

Assuming the leakage of hazardous liquid chemicals in factories and chemical plants caused by natural disasters or human error, it is important to precisely estimate exposure risk and design appropriate evacuation plans and risk‐reduction measures. The exposure risk of indoor residents to leaked chemicals may be estimated using direct measurements or theoretical/numerical estimations of gas‐phase concentrations. Although mathematical models of gas‐phase concentration in the workplace are essential for predicting exposure concentrations at the design stage, practical models have not yet been fully established. We previously proposed practical numerical models to assess indoor gas‐phase concentration distributions after the accidental leakage of liquid chemicals using liquid toluene as a representative hazardous chemical. In this study, the leakage of liquid ethyl acetate, a commonly used organic solvent, into mortar flooring was reproduced in a small test chamber, and numerical analysis was performed. The results showed that the time history of the chamber exhaust concentration had a sharp peak and differed significantly from that of toluene. Three‐dimensional computational fluid dynamics (CFD) analysis incorporating practical ethyl acetate emission models reproduced the external and internal emission characteristics of leaked ethyl acetate on the mortar material. The models showed reasonable agreement with the experimental data.
