The research presented herein aimed at recognition of submicrone particulate matter concentration as well as organic (OC) and elemental (EC) carbon bound to it in a lecture room and students’ laboratory. The 24-h variability of PM1, OC and EC concentration in both rooms were also discussed along with I : O ratio. In the analysed period – the turn of spring and summer – independent of the location (Gliwice – students’ laboratory, Warsaw – lecture room) the indoor concentration of elemental carbon EC was conditioned by the intensity of those contaminants migration along with atmospheric air. Because of this, it can be concluded that in neither of the rooms there was an important source of OC and EC. However, it should be noted, that conditions favourable for different contaminant sorption, in particular those belonging to OC bound to particulate matter, vary in time and space. It is expected, that for other measurement period – for instance in winter, when rooms are ventilated seldom and PM has different composition, the cummulation of indoor contaminants, including OC, may be higher than for warm period.

“…Thus, the infant's health is extremely susceptible to the air pollutant, PM 2.5 , and it can be considered as a toxic precursor to the impairment of a child's neurodevelopment. PM 2.5 -bound persistent organic pollutants (POPs) such as organochlorine pesticides (OCPs), polybrominated diphenyl ethers (PBDEs), and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were reported in previous studies (Chao et al, 2016;Chen et al, 2018b;Zhao et al, 2018). The high organic matter content of PM 2.5 as compared to coarse PMs can be attributed to a higher POPs sorption (Odabasi et al, 2015).…”

Several studies have stated the harmful effects of PM 2.5 to population health, including disruption of neurological development. However, the mechanism behind the neurodevelopmental effects of ambient PM 2.5 and postnatal PBDEs and OCPs exposure is still unknown. Our goal was to determine influence of breastmilk residues, polybrominated diphenyl ethers (PBDEs) and organochlorine pesticides (OCPs), to the infants' neurodevelopment with respect to high and low PM 2.5 exposure areas. The participants were recruited from high PM 2.5 exposure areas (n = 32) and low PM 2.5 exposure areas (n = 23) of southern Taiwan. The extracted 14 PBDEs and 20 OCPs compounds were analyzed using gas chromatography coupled with mass spectrometer. The infants, aging from 8-12 months, were examined by Bayley Scales of Infants and Toddlers Development, Third Edition (Bayley-III) for neurodevelopment. Results showed that high PM 2.5 exposure caused reduced head circumference and had significant effects on the motor skill and social emotional development. For breastmilk PBDEs, a positive correlation between BDE-196 and social emotion, after multivariate analysis with adjustment of confounders, was observed while BDE-99, 196, 197, and 207 showed higher magnitudes in low PM 2.5 areas than in high PM 2.5 areas. For OCPs, only γ-hexachlorcyclohexanes (γ-HCH) presented the significant difference between high and low PM 2.5 exposure areas. Most breastmilk OCPs residues, including 4,4'-dichlorodiphenyltrichloroethane (4,4'-DDT), γ-HCH, endrin, and heptachlor epoxide showed negative impact on the Bayley-III scores after multivariate analysis. In conclusion, infants' neurodevelopment was significantly correlated with the location of PM 2.5 exposure and breastmilk intake of certain PBDEs and OCPs. Breastmilk OCPs might obviously affect infants' neurodevelopment more compared to breastmilk PBDEs based on our finding. Moreover, this study further employs awareness about viable effects of PM 2.5 in infants' neurodevelopment.

“…Ni et al (2011) indicated that human exposure to PM 2.5 -bound PBDEs might have a minor contribution to total non-dietary PBDE exposure. In terms of global scientific reports, few studies have considered PM 2.5 -bound PBDE levels in the indoor environment (Beser et al, 2014;Li et al, 2015a;Xu et al, 2015;Chao et al, 2016;Deng et al, 2016). To our knowledge, there are no known reports that have investigated the levels of PM 2.5 -bound DP, NBFRs, or PBDD/Fs in the indoor environment.…”

“…There have been a significant number of PBDE studies considering PBDE contamination of foodstuff, in human specimens, soil, indoor dust, and indoor and outdoor air, including gas and total suspended particulate matter (TSP) Chou et al, 2016;Gou et al, 2016a). However, only a few studies have focused on PBDEs as respirable fine particulates (PM 2.5 ) (Li et al, 2015b;Chao et al, 2016). Unlike PBDEs, the levels and fate of DP, NBFRs, and PBDD/Fs in indoor air and dust are scarce.…”

Non-polybrominated diphenyl ether (non-PBDE) halogenated fire retardants (HFRs) such as new or novel brominated fire retardants (NBFRs) and dechlorane plus (DP) have been widely spread in the environment and recognized as emerging persistent organic pollutants (POPs) in the recent years, mainly due to the continuous increase in their global demand, especially after the worldwide restrictions on PBDE use. Polybrominated dibenzo-p-dioxins/furans (PBDD/Fs) are the unintentional byproducts of PBDE commercial formulations in the indoor environment. Although HFRs, including NBFRs, DP, and PBDD/Fs, are ubiquitous in the indoor environment due to the large-volume release from the surfaces of consumer products, only a few in vitro and in vivo studies have addressed their toxic effects. In this review article, global data on NBFRs, including decabromodiphenyl ethane (DBDPE), 1,2-bis(2,4,6-tribromophenoxy) ethane (BTBPE), bis(2-ethylhexyl)-3,4,5,6-tetrabromophthalate (BEH-TEBP), and 2-ethylhexyl-2,3,4,5-tetrabromobenzoate (EH-TBB), DP, including syn-DP and anti-DP, and PBDD/Fs in indoor aerosol and dust are summarized from recent literature. Based on the gathered data, indoor dust is a major sink for indoor contamination and is of great concern due to the fact that dust ingestion is one of the primary routes for human exposure to these chemicals. Lastly, the toxic effects of NBFRs, DP, and PBDD/Fs identified in in vitro and in vivo studies are summarized and discussed based on the current published reports. However, there is still a lack of sufficient toxicity data for assessing their risks. Future works are encouraged to focus on indoor PM 2.5 -bound HFR levels to further evaluate their toxic effects on human health.
