Kinetics and mechanism of the oxidation of dimethylsulfoxide (DMSO) and methanesulfinate (MSI−) by OH radicals in aqueous medium
Abstract Kinetics and product distribution of the reaction of dimethylsulfoxide (DMSO) and methanesulfinate (MSI − ) with OH radicals and H 2 O 2 in the aqueous phase are reported in this work. DMSOExpand
Transformations of Pesticides in the Atmosphere: A State of the Art
The current knowledge about transformation rates and products of pesticides in the atmosphere is reviewed. Reactive species and their concentrations in the atmosphere are presented. Reactions ofExpand
Development and application of a simultaneous SPE-method for polycyclic aromatic hydrocarbons (PAHs), alkylated PAHs, heterocyclic PAHs (NSO-HET) and phenols in aqueous samples from German Rivers and
To investigate their occurrence in river basins two sensitive analytical methods for the simultaneous extraction of 86 substances including NSO-HETs, classical EPA-PAHs, alkylated PAHs and phenols were developed: liquid-liquid extraction for the whole water phase and solid phase extracting for the dissolved water phase only.

OH Radical Reactivity of Airborne Terbuthylazine Adsorbed on Inert Aerosol
The reaction of terbuthylazine (TBA) with OH radicals was investigated in an aerosol smog chamber (2400 L). TBA was adsorbed well below a monolayer on silicon dioxide as inert carrier. OH radicalsExpand
Atmospheric degradation of a semivolatile aerosol-borne pesticide: Reaction of OH with pyrifenox (an Oxime-Ether), adsorbed on SiO2
The reactivity of both isomers (Z and E) of pyrifenox (2′,4′-dichloro-2-(3-pyridyl)acetophenone (E,Z)O-methyloxime), adsorbed on quartz-aerosol as an inert carrier, against OH radicals from theExpand
Plant traits affecting herbivory on tree recruits in highly diverse subtropical forests.
This study indicates that previously neglected measures of large-scale geographical host distribution are important factors influencing local herbivory patterns among plant species. Expand
Investigation of the photochemistry and quantum yields of triazines using polychromatic irradiation and UV-spectroscopy as analytical tool
Abstract Photochemical reactions of atrazine, propazine, simazine, terbuthylazine, ametryn and atraton were investigated in aqueous and buffered (pH=7–9) solutions (containing a few percent ofExpand
OH radical reactivity of pesticides adsorbed on aerosol materials: first results of experiments with filter samples.
Preliminary results of a new method to investigate the OH radical reactivity of semi-volatile organic compounds (e.g., pesticides) are presented and Simazine and isoproturon were found to react with a comparable OH rate constant with respect to terbuthylazine. Expand
In situ air-water and particle-water partitioning of perfluorocarboxylic acids, perfluorosulfonic acids and perfluorooctyl sulfonamide at a wastewater treatment plant.
Field-based values agree well with equilibrium partitioning data reported in the literature, suggesting that any in situ generation from precursors, if they are present in this system, occurs at a slower rate than the rate of approach to equilibrium. Expand
