“…Furthermore, several semi-volatile organic compounds (SVOCs) include known neurotoxins that are associated with negative behavioural outcomes. 158,159 The connections between airborne toxins and mental health outcomes are of particular concern in the indoor built environment where there is a frequent use of household cleaners and chemicals with such compounds, as well as SVOCs, which are common in building materials.…”

Global urbanization, combined with evidence of increased prevalence of mental illness in urban environments, highlights a need to investigate potential connections between the built environment and mental health. Previous research has shown that the built environment may impact occupant mental health through its effects on connection to nature, personal control and indoor air quality. Contact with the natural environment has physiological and psychological benefits; consequently, reduced contact or exposure leads to negative mental health outcomes. The control an occupant has in the built environment can alter the mental health of individuals through direct pathways, such as prevention of exposures to environmental stressors and indirect pathways, such as social connections to others. Indoor air quality is connected to the mental health of built environment occupants, as particulate matter, malodorous irritants and toxins have all been shown to alter mental well-being. Opportunities for architects and engineers to optimize building designs that improve occupant mental health include planned urban greenspace, personalized temperature control and building ventilation. To understand optimization targets, interdisciplinary research utilizing controlled experiments are needed to confirm causality and improve our current understanding of mechanisms underlying the association between the built environment and mental health.

“…As we know, PAEs are a typical type of endocrine-disrupting chemical and pose potential threats to the environment and humans. DBP, DEP, and DEHP have been reported to be the compounds that contribute most to different health effects after exposure to the residential indoor environment via ingestion, inhalation, and skin absorption, especially in children (Pelletier et al, 2018;Weiss et al, 2018). Li's research illustrated that the PAEs can also react with pollutants in outdoor air and contribute secondary organic aerosols (Li et al, 2018).…”

Photolysis and photocatalysis of typical phthalic acid esters (dimethyl phthalate, DMP; diethyl phthalate, DEP; dibutyl phthalate, DBP) were carried out in UV, UV/TiO 2 , and UV-Vis/Bi 2 WO 6 systems. All of the selected phthalic acid esters and their decomposition byproducts were subjected to qualitative and quantitative analysis through HPLC and GC-MS. The results of 300 min of photolysis and photodegradation reaction were that each system demonstrated different abilities to remove DMP, DEP, and DBP. The UV/TiO 2 system showed the strongest degradation ability on selected PAEs, with removal efficiencies of up to 93.03, 92.64, and 92.50% for DMP, DEP, and DBP in 90 min, respectively. UV-Vis/Bi 2 WO 6 had almost no ability to remove DMP and DEP. However, all of the systems had strong ability to degrade DBP. On the other hand, the different systems resulted in various byproducts and PAE degradation pathways. The UV system mainly attacked the carbon branch and produced o-hydroxybenzoates. No ring-opening byproducts were detected in the UV system. In the photocatalytic process, the hydroxyl radicals produced not only attacked the carbon branch but also the benzene ring. Therefore, hydroxylated compounds and ring-opening byproducts were detected by GC-MS in both the UV/TiO 2 and UV-Vis/Bi 2 WO 6 photocatalytic systems. However, there were fewer products due to direct hole oxidation in the UV-Vis/Bi 2 WO 6 system compared with the UV/TiO 2 system, which mainly reacted with the pollutants via hydroxyl radicals.

Organochlorine pesticides (OCPs) in air‐conditioner filter dust of indoor urban setting: Implication for health risk in a developing country

et al. 2020

This preliminary investigation highlights the occurrence of organochlorine pesticides (OCPs) in the indoor environment of a megacity, Lahore, Pakistan using the dust ensnared by air-conditioner filters. The Σ 16 OCPs concentration ranged from 7.53 to 1272.87 ng/g with the highest percent contribution by ΣDDT (dichlorodiphenyltrichloroethane; 87.21%) and aldrin (6.58%). The spatial variation of OCPs profile revealed relatively higher concentration from homes near to agricultural and abandoned DDT manufacturing sites. Calculated isomer ratios revealed historic sources of hexachlorocyclohexanes (HCHs) and the fresh input of technical DDT and chlordane by the dwellers. The air conditioner dust was helpful to better understand the health risk in the indoor environment. So far a high lifetime cancer risk (10 −3 ) was predicted for toddlers via accidental ingestion, inhalation, and dermal exposure. Similarly, the non-carcinogenic risk-based hazard quotient was found to be high for toddlers (6.94) and within the permissible limit (<1) for adults.

Abstract: In view of uncertainties related to compounds' toxicity for humans, these results justify the implementation of preventive measures, as well as the production of more standardized and comprehensive toxicological data for some compounds.
