Article Synopsis
  • Bromochloro alkanes (BCAs) are newly identified flame retardants similar to other Persistent Organic Pollutants and have been found in environmental samples for the first time, yet no standard methods for their quantification exist.
  • This study involves the synthesis of 16 custom standards to explore quantification strategies for BCAs in indoor dust, achieving an average measurement accuracy of 81% and meeting EU accuracy criteria in 89% of cases during fortification trials.
  • Despite these advancements, applying the quantification method to actual dust samples showed a low correlation with the prototype standards, highlighting the need for more diverse mixture standards for reliable BCA quantification in environmental samples.

Background: In response to COVID-19, attention was drawn to indoor air quality and interventions to mitigate airborne COVID-19 transmission. Of developed interventions, Corsi-Rosenthal (CR) boxes, a do-it-yourself indoor air filter, may have potential co-benefits of reducing indoor air contaminant levels.

Objective: We employed non-targeted and suspect screening analysis (NTA and SSA) to detect and identify volatile and semi-volatile organic contaminants (VOCs and SVOCs) that decreased in indoor air following installation of CR boxes.

In this study, very short-, short-, medium-, and long-chain chlorinated paraffins (vSCCPs, SCCPs, MCCPs and LCCPs, respectively) were measured in 40 indoor dust samples from four countries including Japan (n = 10), Australia (n = 10), Colombia (n = 10) and Thailand (n = 10). Homologues of the chemical formula CHCl ranging C and Cl were analysed using liquid chromatography coupled to Orbitrap high resolution mass spectrometry (LC-Orbitrap-HRMS) and integrated using novel custom-built CP-Seeker software. CPs were detected in all dust samples with MCCPs the dominant homologue group in all countries.

The COVID-19 pandemic brought new emphasis on indoor air quality. However, few studies have investigated the impact of air filtration, a COVID-mitigation approach, on indoor air concentrations of semivolatile organic compounds (SVOCs). Using a quasi-experimental design, we quantified the impact of a relatively low-cost "do-it-yourself" air filter (Corsi-Rosenthal Box; CR Box) on indoor air concentrations of 42 PFAS and 24 other SVOCs.

Upholstered furniture has been a major source of chemical flame retardant (FR) exposures in US homes since the 1970s. FRs are a large group of chemicals, many of which are associated with adverse health effects, including cancer, reproductive toxicity, and neurotoxicity. California homes have some of the highest dust concentrations of FRs, due to Technical Bulletin 117 (TB117), California's outdated flammability standard for furniture foam that was generally followed across the US and Canada.

Nearly all Americans have detectable concentrations of endocrine disrupting chemicals from consumer products in their bodies, and expert panels recommend reducing exposures. To inform exposure reduction, we investigated whether consumers who are trying to avoid certain chemicals in consumer products have lower exposures than those who are not. We also aimed to make exposure biomonitoring more widely available.

Green building design has substantially minimized environmental impacts by reducing energy consumption compared with traditional buildings. Yet, it is not uncommon for a green building to meet the highest criteria for energy efficiency and be built with materials that contain chemicals hazardous to occupant health. Because of this discrepancy in achieving holistic sustainability, the architecture/engineering/construction (AEC) industry has never been more interested in occupant health and well-being than it is today.
