“…As of exogenous substances, we anticipate soil particles to dominate dry deposition on leaves close to the ground. As fully grown N. tobacco plants are 1−3 m tall with leaves distributed across the whole height, 351 we scaled Γ soil to account for the fact that only 16−50% of the leaves hang less than 50 cm from the soil. Last, wet exogenous contributions include the applied pesticide, other formulation components (e.g., surfactants), and other organics present in the aqueous solvent (whose contribution we assume comparable to natural rain, and thus negligible).…”

Atmospheric chemists have historically treated leaves as inert surfaces that merely emit volatile hydrocarbons. However, a growing body of evidence suggests that leaves are ubiquitous substrates for multiphase reactions−implying the presence of chemicals on their surfaces. This Review provides an overview of the chemistry and reactivity of the leaf surface's "chemical landscape", the dynamic ensemble of compounds covering plant leaves. We classified chemicals as endogenous (originating from the plant and its biome) or exogenous (delivered from the environment), highlighting the biological, geographical, and meteorological factors driving their contributions. Based on available data, we predicted ≫2 μg cm −2 of organics on a typical leaf, leading to a global estimate of ≫3 Tg for multiphase reactions. Our work also highlighted three major knowledge gaps: (i) the overlooked role of ambient water in enabling the leaching of endogenous substances and mediating aqueous chemistry; (ii) the importance of phyllosphere biofilms in shaping leaf surface chemistry and reactivity; (iii) the paucity of studies on the multiphase reactivity of atmospheric oxidants with leaf-adsorbed chemicals. Although biased toward available data, we hope this Review will spark a renewed interest in the leaf surface's chemical landscape and encourage multidisciplinary collaborations to move the field forward.

“…As of exogenous substances, we anticipate soil particles to dominate dry deposition on leaves close to the ground. As fully grown N. tobacco plants are 1 to 3 m tall with leaves distributed across the whole height,351 we scaled Γ > 1 µg cm -2 . Formulations also contains surfactants, and we thus predict more leaching through cuticular water pores than with natural wetness.…”

Atmospheric chemists have historically treated plant leaves as inert surfaces that merely emit volatile hydrocarbons through their stomata. However, a growing body of evidence suggests that leaves are ubiquitous substrates for multiphase reactions of atmospheric relevance – implying the presence of chemicals on their surfaces. This Review provides an evidence-based overview of the chemistry and reactivity of the leaf surface’s “chemical landscape”, the dynamic ensemble of molecules and particles that cover plant leaves. We classified chemicals as endogenous (originating from the leaf and its biome) or exogenous (delivered from the environment), highlighting the biological, geographical, and meteorological factors driving their relative contributions. Based on available data, we predicted ≫ 2 µg cm-2 of organics on a typical leaf, leading to a global estimate of ≫ 3 Tg available for multiphase reactions. Our work also highlighted three major knowledge gaps: (i) the key (but still overlooked) role of ambient water in enabling the leaching of endogenous substances and mediating aqueous chemistry; (ii) the role of phyllosphere biofilms in shaping leaf surface chemistry and reactivity; (iii) the paucity of studies on the multiphase reactivity of main atmospheric oxidants with leaf-adsorbed chemicals. Although biased towards available data, we hope this Review will spark a renewed interest on the leaf surface’s chemical landscape and motivate the establishment of multidisciplinary collaborations to move the field forward.
