“…Background H 2 O 2 levels in the simulated residential room during unperturbed periods prior to cleaning applications were on average (±SD) 0.64 (±0.43) ppbv, below the detection limit (64% of data were below LOD). This is comparable to H 2 O 2 mixing ratios observed in urban ambient outdoor atmospheres (<1 ppbv) 42,43 but higher than those in an unperturbed office and a simulated indoor environment (<0.26 ppbv) using offline sampling and analytical methods. 23,24 To provide context, the average H 2 O 2 mixing ratios measured in a unperturbed student office and an engineering laboratory during ROCC were 1.6 (±1.1) and 2.1 (±0.49) ppbv, respectively.…”

Activities such as household cleaning can greatly alter the composition of air in indoor environments. We continuously monitored hydrogen peroxide (H2O2) from household non-bleach surface cleaning in a chamber designed to simulate a residential room. Mixing ratios of up to 610 ppbv gaseous H2O2 were observed following cleaning, orders of magnitude higher than background levels (sub-ppbv). Gaseous H2O2 levels decreased rapidly and irreversibly, with removal rate constants (k H2O2 ) 17–73 times larger than air change rate (ACR). Increasing the surface-area-to-volume ratio within the room caused peak H2O2 mixing ratios to decrease and k H2O2 to increase, suggesting that surface uptake dominated H2O2 loss. Volatile organic compound (VOC) levels increased rapidly after cleaning and then decreased with removal rate constants 1.2–7.2 times larger than ACR, indicating loss due to surface partitioning and/or chemical reactions. We predicted photochemical radical production rates and steady-state concentrations in the simulated room using a detailed chemical model for indoor air (the INDCM). Model results suggest that, following cleaning, H2O2 photolysis increased OH concentrations by 10–40% to 9.7 × 105 molec cm–3 and hydroperoxy radical (HO2) concentrations by 50–70% to 2.3 × 107 molec cm–3 depending on the cleaning method and lighting conditions.

“…Gaseous POs have been ubiquitously detected in the atmosphere (Table ), with implications on atmospheric radical budget and oxidation capacity. Methyl hydroperoxide (MHP) is the simplest and most abundant PO in the atmosphere. ,,− The MHP level was measured at up to 1.5 ppb in the marine boundary layer of the tropical South Atlantic, 1.4 ppb in North America, up to 2.5 ppb in central Europe, 0.5–2 ppb in South Korea, 0.1–3 ppb in central Japan, and up to 2 ppb in different regions of China. ,,,, PAA is another important atmospheric PO with contributions to the oxidation capacity and SOA formation in the troposphere. ,, A maximum level of 1 ppb PAA with a diurnal peak occurring in the afternoon over rural and urban China was reported by Zhang et al Other C 1 and C 2 gaseous POs such as bishydroxymethyl hydroperoxide, hydroxymethyl hydroperoxide, 1-hydroxy-ethyl hydroperoxide, and ethyl hydroperoxide were also measured with concentrations up to 0.8 ppb at a rural site in southern China by Hua et al using online HPLC with postcolumn derivatization and fluorescence detection, and the formation of these small POs was found to be mostly related to the local photochemical activity.…”

Organic Peroxides in Aerosol: Key Reactive Intermediates for Multiphase Processes in the Atmosphere

et al. 2023

Organic peroxides (POs) are organic molecules with one or more peroxide (−O−O−) functional groups. POs are commonly regarded as chemically labile termination products from gas-phase radical chemistry and therefore serve as temporary reservoirs for oxidative radicals (HO x and RO x ) in the atmosphere. Owing to their ubiquity, active gasparticle partitioning behavior, and reactivity, POs are key reactive intermediates in atmospheric multiphase processes determining the life cycle (formation, growth, and aging), climate, and health impacts of aerosol. However, there remain substantial gaps in the origin, molecular diversity, and fate of POs due to their complex nature and dynamic behavior. Here, we summarize the current understanding on atmospheric POs, with a focus on their identification and quantification, state-of-the-art analytical developments, molecular-level formation mechanisms, multiphase chemical transformation pathways, as well as environmental and health impacts. We find that interactions with SO 2 and transition metal ions are generally the fast PO transformation pathways in atmospheric liquid water, with lifetimes estimated to be minutes to hours, while hydrolysis is particularly important for α-substituted hydroperoxides. Meanwhile, photolysis and thermolysis are likely minor sinks for POs. These multiphase PO transformation pathways are distinctly different from their gas-phase fates, such as photolysis and reaction with OH radicals, which highlights the need to understand the multiphase partitioning of POs. By summarizing the current advances and remaining challenges for the investigation of POs, we propose future research priorities regarding their origin, fate, and impacts in the atmosphere.

“…Considering the important roles of H 2 O 2 in tropospheric chemistry as well as its adverse impact on the ecosystem, a growing number of measurements for atmospheric H 2 O 2 have been reported in different places, including urban, rural and mountain sites as well as airborne measurements (Gong et al., 2018; Lee et al., 1997; Liang et al., 2013; Tanner & Schorran, 1995; Walker et al., 2006; Wang et al., 2016; Watanabe et al., 2016; Zhang et al., 2018). In general, relatively high H 2 O 2 levels (from several ppb to more than 10 ppb) usually occur in polluted regions or pollution plumes, for example, H 2 O 2 mixing ratio up to 11.3 ppb was observed in a seriously polluted rural site in China (Wang et al., 2016) and 11.5 ppb in pollution plumes during flights in the marine troposphere (O'Sullivan et al., 1999).…”

Hydrogen peroxide (H2O2) acts as a terminal sink for atmospheric HOx radicals (OH and HO2), playing a key role in tropospheric O3 formation. However, there are few field measurements of atmospheric H2O2 to assess its role in O3 formation, especially for the seriously polluted region of the North China Plain. In this study, H2O2 concentrations were measured at the foot of Mt. Tai from May to July 2018 and the summit of Mt. Tai from May to June 2019, with average values of 0.93 ± 1.01 and 2.05 ± 1.20 ppb, respectively. H2O2 exhibited a pronounced diurnal variation with a noon‐peak at the foot of Mt. Tai, which could be well reproduced by a gas‐phase box model with H2O2 dry deposition velocity of 3 cm s−1 included, indicating H2O2 was mainly photochemically produced. Modeling analysis showed H2O2 production at the foot was most sensitive to alkenes and aromatics, while the source and sink for H2O2 were dominated by HO2 recombination and dry deposition, respectively. Compared with the summer‐measurement in 2007, the remarkable elevation of H2O2 at the summit might be ascribed to volatile organic compounds (VOCs) increase and SO2 decline. Both H2O2‐O3 correlation and H2O2/NOz ratio suggested O3 formation at the foot of Mt. Tai was mainly VOC‐sensitive in the early morning and shifted to NOx‐sensitive thereafter. Therefore, reduction of VOCs emission especially for the reactive species of alkenes and aromatics in the morning as well as NOx emission around noontime will be effective for mitigating the serious O3 (as well as H2O2) pollution in Tai'an city.
