TY - JOUR ID - 560882 AU - Dolinová, Jindřiška - Klánová, Jana - Klán, Petr - Holoubek, Ivan PY - 2004 TI - Photodegradation of organic pollutants on the spruce needle wax surface under laboratory conditions JF - Chemosphere VL - 57 IS - 10 SP - 1399 EP - 1399 PB - Elsevier Science Ltd. SN - 00456535 KW - Photochemistry KW - pollutants KW - needles KW - wax N2 - The photochemistry of selected organic compounds, including common pollutants, on the paraffin (as a model matrix) and spruce wax surfaces was studied under laboratory conditions. Two model transformations were evaluated: (1) intramolecular rearrangements of valerophenone and 2-nitrobenzaldehyde, and (2) hydrogen abstraction between an excited benzophenone and the hydrocarbon paraffin/wax chains. The steric or polar influence of the solid matrix on conformational and translational motion, its optical properties, hydrogen abstraction probabilities, and consequences of the guest-molecule segregation are discussed in this work. Furthermore, the photochemical reactivity of some common anthropogenic pollutants, such as chlorinated biphenyls (4-chlorobiphenyl, 2,4-dichlorobiphenyl, and 4,4-dichlorobiphenyl), 4-chlorophenol, and DDT, was evaluated. The surface of spruce wax is presented as probable reaction medium for photochemical transformations. Although the matrix presents certain restrictions for bimolecular reactions, common photodegradations should be generally feasible in nature. In addition, paraffin was found to be a suitable model matrix for the studies of possible photochemical transformations that can occur on natural plant surfaces. ER -
