Abstract. In this study, trends of 21st-century ground-level ozone and precursors were examined across South America, a less-studied region where trend estimates have rarely been comprehensively addressed. Therefore, we provided an updated regional analysis based on validated surface observations. We tested the hypothesis that recent increasing trends, mostly in urban environments, resulted from intense wildfires driven by extreme meteorological events impacting cities preexisting volatile...
This study aims to evaluate the reliability of volatile organic compound (VOC) detection and identification in complex coastal terrains Central Chile. In this zone, frequent complaints by residents prompted a new National Ambient Air Quality Standard for benzene 2023, set at 0.9 ppbv (nmol mol-1). The monitoring site is located Concón City, near an oil refinery where we combine Proton Transfer Reaction Time Flight Mass Spectrometry (PTR–TOF–MS), Gas Chromatograph...
