“…Twenty-one ESPs were wiped with eight wet (DI H 2 O) PVC filters (26). These filters were allowed to dry at least 72 h, then weighed and chemically analyzed using a microwave digestion methodology, with modified parameters to increase the recovery of metal analytes (27,28). FBs were treated identically, where a wet PVC filter was used to wipe a clean ESP.…”

Background: Particulate matter (PM) air pollution causes deleterious health effects; however, less is known about health effects of indoor air particulate matter (IAP). Objective: To understand whether IAP influences distinct mechanisms in the development of respiratory tract infections, including bacterial growth, biofilm formation, and innate immunity. Additionally, we tested whether IAP from Iowa houses of subjects with and without recent respiratory exacerbations recapitulated the National Institute of Standards and Technology (NIST) IAP findings. Methods: To test the effect of NIST and Iowa IAP on bacterial growth and biofilm formation, we assessed Staphylococcus aureus growth and Pseudomonas aeruginosa biofilm formation with and without the presence of IAP. To assess the effect of IAP on innate immunity, we exposed primary human airway surface liquid (ASL) to NIST, and Iowa IAP. Lastly, we tested whether specific metals may be responsible for effects on airway innate immunity. Results: NIST and Iowa IAP significantly enhanced bacterial growth and biofilm formation. NIST IAP (whole particle and the soluble portion) impaired ASL antimicrobial activity. IAP from one Iowa home significantly impaired ASL antimicrobial activity (p < 0.05), and five other homes demonstrated a trend (p ≤ 0.18) of impaired ASL antimicrobial activity. IAP from homes of subjects with a recent history of respiratory exacerbation tended (p = 0.09) to impair ASL antimicrobial activity more than IAP from homes of those without a history respiratory exacerbation. Aluminum and Magnesium impaired ASL antimicrobial activity, while copper was bactericidal. Combining metals varied their effect on ASL antimicrobial activity. Stapleton et al. Indoor PM Affects Respiratory Health Conclusions: NIST IAP and Iowa IAP enhanced bacterial growth and biofilm formation. ASL antimicrobial activity was impaired by NIST IAP, and Iowa house IAP from subjects with recent respiratory exacerbation tended to impair ASL antimicrobial activity. Individual metals may explain impaired ASL antimicrobial activity; however, antimicrobial activity in the presence of multiple metals warrants further study.

“…13 35 The use of HCl as part of the digestion mixture is mandatory to solubilise Sb(V) as SbCl6and prevent Sb adsorption to silica material. 36 The use of HCl has the added advantage of dissolving common iron and silica minerals and apatite. 37 We have evaluated the use of HNO3-HCl mixtures for releasing Sb from mine contaminated sediments 38 and found Sb is nearly quantitatively extracted (using a 2:…”

“…Treatment of antimony data in this report is incomplete for two reasons. First, digestions using only nitric acid are known to yield variable recoveries [24] and second, some of the analyses were performed by inductively coupled plasma-optical emission spectrometry (ICP-OES) and some by inductively coupled plasma-mass spectrometry (ICP-MS). The former had an antimony detection limit of approximately 20 mg kg À1 which was too high for most of these samples, rendering some of the comparisons problematic.…”
