Biogenic volatile organic compounds (BVOCs) play a crucial role in urban air quality by contributing to ground-level ozone (O₃) and secondary aerosol (SOA) formation. While forests help mitigate pollution, BVOC emissions can interact with anthropogenic pollutants, exacerbating pollution. These are influenced seasonality urbanization, affecting both their rates chemical compositions [1]. In the Metropolitan Area of São Paulo (MASP), Atlantic Forest provides valuable...

Winter atmospheric measurements of gaseous lower carbonyl and carboxylic acids were carried out simultaneously (in 1999) at two distinct urban sites located in the city São Paulo, Brazil. The greater metropolitan area Paulo is largest industrialized region Latin America has a highly polluted atmosphere. It an unconventional mix vehicle types that variety gasoline blends, including oxygenated ones, are used. Mixing ratios formic acetic ranged, respectively, from 0.6 to 19.4 0.1 10.6 ppbv one...

Here, we proposed that volatile organic compounds (VOC), specifically methyl salicylate (MeSA), mediate the formation of calcium oxalate crystals (COC) in defence against ozone (O3) oxidative damage. We performed experiments using Croton floribundus, a pioneer tree species is tolerant to O3 and widely distributed Brazilian forest. This constitutively produces COC. exposed plants controlled fumigation experiment assessed biochemical, physiological, morphological parameters. induced...

Plants emit a broad number of Biogenic Volatile Organic Compounds (BVOCs) that can impact urban ozone (O 3 ) production. Conversely, the O is phytotoxic pollutant causes unknown alterations in BVOC emissions from native plants. In this sense, here, we characterized constitutive and -induced BVOCs for two (2dO four (4dO days exposure dose 80 ppb) evaluated response by histochemical techniques to detect programmed cell death (PCD) hydrogen peroxide (H 2 three Brazilian species.

This study aimed to analyze critically the potential of Ipomoea nil ‘Scarlet O'Hara’ for O3 biomonitoring in sub-tropics. Four field experiments (one each season 2006) were carried out a location city São Paulo mainly polluted by O3. Each experiment started with 50 plants, and lasted 28 days. Sub-lots five plants taken at intervals between three or four days long. Groups also exposed closed chambers filtered air 40, 80 ppb consecutive hours day six The percentage leaf injury (interveinal...

Troposphere ozone (O3) is an important photochemical pollutant due to its high reactivity and phytotoxicity. Plants can show microscopic damage caused by this gas before the detection of visible symptoms. The present study aimed improve our knowledge concerning effects O3 on Ipomoea nil L. cv. Scarlet O'Hara leaves. were exposed at a site in São Paulo city, with levels O3, fumigation was also carried out. In plants environment, without symptoms, hypersensitive response-like (HR-like)...
