The mechanisms leading to the formation of secondary organic aerosol (SOA) are an important subject ongoing research for both air quality and climate. Recent laboratory experiments suggest that reactions taking place in atmospheric liquid phase represent a potentially significant source SOA mass. Here, we report direct ambient observations mass from processing biomass-burning emissions aqueous phase. Aqueous (aqSOA) is observed fog water wet aerosol. aqSOA biomass burning contributes "brown"...
This work is an overview of the oxidative potential (OP) values up to date measured in Italy, with aim provide a picture spatial and seasonal variability OP various geographical areas across Italy. The summarized works used common acellular assays-based dithiothreitol (OPDTT), ascorbic acid (OPAA), glutathione (OPGSH), 2′,7′-dichlorodfluorescein (OPDCFH) assays. paper describes association responses PM chemical composition, sensitivity assays components emission sources, size distribution...
In the analysis of a neuroblastoma xenograft implanted in mice using two-dimensional maps, some 85 proteins were found to be up- or down-regulated (out total 264 detected by medium-sensitivity colloidal Coomassie stain). When these spots eluted and analysed mass spectrometry quadrupole time flight spectrometer, number envelopes different polypeptide chains. Out 74 identified, 52 (71%) singlets, 14 (19%) doublets, 6 (8%) triplets, 1 was quadruplet quintuplet. Analysis DeltapI DeltaMr all...
This paper describes the in situ monitoring of indoor air quality (IAQ) two dwellings, using low-cost IAQ sensors to provide high-density temporal and spatial data. measurements were conducted over 2-week periods kitchen bedroom each home during winter, spring, summer seasons, characterized by different outside parameters, that simultaneously measured. The mean PM2.5 concentrations about 15 μg m−3 they dropped values close 10 spring increased levels 13 summer. During winter campaign, was...
Abstract The concentrations of polycyclic aromatic hydrocarbons (PAHs) and quinones, a subgroup oxygenated PAHs (oxy-PAHs), were measured in PM 2.5 samples collected during warm (May–June 2019) cold (February–March 2020) seasons the city Bologna, Italy. Total concentration was nearly double winter (6.58 ± 1.03 ng m −3 ) compared with spring (3.16 0.53 ), following trend mass concentration. Molecular diagnostic ratios suggested that, together traffic, biomass burning dominant emission source...
Abstract. This paper presents the findings from a collaborative interlaboratory comparison exercise designed to assess oxidative potential (OP) measurements conducted by 20 laboratories worldwide. study represents an innovative effort as first specifically aimed at harmonising this type of OP assay, setting new benchmark in field. Over last decade, there has been noticeable increase studies, with numerous research groups investigating effects exposure air pollution particles through...
Abstract Solvent extraction of PM 2.5 samples collected on the filter is a preliminary step for assessing oxidative potential (OP) using cell-free assays, as dithiothreitol (DTT) and ascorbic acid (AA) assays. In this study, we evaluated effect solvent choice by extracting ambient with different solvents: methanol, organic solvent, two aqueous buffers, i.e., phosphate buffer (PB) Gamble’s solution (G), lung fluid surrogate solution. Both measured volume-based OP V DTT AA responses varied...
Quantifying the component-specific contribution to oxidative potential (OP) of ambient particle matter (PM) is key information properly representing its acute health hazards. In this study, we investigated interactions between major contributors OP, i.e., transition metals and quinones, highlight relative effects these species total OP. Several synergistic antagonistic were found that significantly change redox properties their binary mixtures, increasing or decreasing values computed by a...
Oxidative potential (OP) of particulate matter (PM) is gaining strong interest as a promising health exposure metric. This study investigated OP large set PM
