The atmospheric impacts of monoterpene ozonolysis on global stabilised Criegee intermediate budgets and SO₂ oxidation: experiment, theory and modelling by M. J. Newland, M. J. Newland, A. R. Rickard, A. R. Rickard, T. Sherwen, M. J. Evans, M. J. Evans, L. Vereecken, L. Vereecken, A. Muñoz, M. Ródenas, W. J. Bloss

“…In this work we apply experimental, theoretical and numerical modelling methods to quantify the atmospheric impacts, abundance and fate of the structurally diverse SCIs derived from the ozonolysis of monoterpenes, the second most abundant group of unsaturated hydrocarbons in the atmosphere. We have investigated the removal of SO₂ by SCIs formed from the ozonolysis of three atmospherically important monoterpenes (<i>α</i>-pinene, <i>β</i>-pinene and limonene) in the presence of varying amounts of water vapour in large-scale simulation chamber experiments that are representative of boundary layer conditions. …”

FACTORS DETERMINING THE PHYTOPLANKTON VARIABILITY IN THE SWAMPS OF THE MOMPOSINA DEPRESSION (COLOMBIA) by Yasmín Plata-Díaz, Astrid-Lorely Pimienta-Rueda

“…Variations in phytoplankton composition were not related to the hydrological periods studied. pH, NO3, conducti-vity and the organic load (BOD5), as well as variables indirectly related to the industrial operation (chlorides and COD) were determining variables. Total hydrocarbons were not a significant variable in the community structure.…”
