Atmospheric impact of 2-methylpentanal emissions: kinetics, photochemistry, and formation of secondary pollutants [PDF]

Atmospheric Chemistry and Physics, 2023
The tropospheric fate of 2-methylpentanal (2MP) has been investigated in this work. First, the photochemistry of 2MP under simulated solar conditions was investigated by determining the UV absorption cross sections (220–360 nm) and the effective ...

Evaluation of the daytime tropospheric loss of 2-methylbutanal [PDF]

Atmospheric Chemistry and Physics, 2022
Saturated aldehydes, e.g. 2-methylbutanal (2 MB, CH3CH2CH(CH3)C(O)H), are emitted into the atmosphere by several biogenic sources. The first step in the daytime atmospheric degradation of 2 MB involves gas-phase reactions initiated by hydroxyl (OH ...

Atmospheric fate of a series of saturated alcohols: kinetic and mechanistic study [PDF]

Atmospheric Chemistry and Physics, 2020
The atmospheric fate of a series of saturated alcohols (SAs) was evaluated through kinetic and reaction product studies with the main atmospheric oxidants. These SAs are alcohols that could be used as fuel additives.

Gas-Phase Reactivity of OH Radicals With Ammonia (NH3) and Methylamine (CH3NH2) at Around 22 K

Frontiers in Astronomy and Space Sciences, 2022
Interstellar molecules containing N atoms, such as ammonia (NH3) and methylamine (CH3NH2), could be potential precursors of amino acids like the simplest one, glycine (NH2CH2COOH).

Evaluation of Genotoxic and Cytotoxic Effects in Human Peripheral Blood Lymphocytes Exposed In Vitro to Neonicotinoid Insecticides News

Journal of Toxicology, Volume 2012, Issue 1, 2012., 2012
Calypso (thiacloprid), Poncho (clothianidin), Gaucho (imidacloprid), and Jade (imidacloprid) are commercial neonicotinoid insecticides, a new class of agrochemicals in México. However, genotoxic and cytotoxic studies have not been performed. In the present study, human peripheral blood lymphocytes (PBL) were exposed in vitro to different concentrations

Intercomparison of Daily Maximum and Minimum Temperature Gridded Products Over Mainland Spain

International Journal of Climatology, Volume 45, Issue 14, 30 November 2025.
Extreme event of min. temperature occurred between January 26th and February 2nd 2005. Observational uncertainty is greater for minimum than for maximum temperatures, although it depends on the analysis dimension considered, so intercomparison analyses are needed.
