| Zusammenfassung |
| The study of iodine emission and particle formation from Laminaria Digitata has been carried out in an atmosphere simulation chamber. Samples were stored in an aquarium and used within 7 days of collection. Individual Laminaria plants were placed in a container in the chamber and initially covered with sea water. During experiments, the seawater was removed from the container, gradually exposing the sample to chamber air containing ozone. Incoherent Broadband Cavity Enhanced Absorption Spectroscopy (IBBCEAS) was used to measure I2, IO and OIO during each experiment. Particle formation was measured using a nano-SMPS. Large particle bursts were seen immediately after exposure of Laminaria Digitata and this was true even for some experiments where ozone was absent. |
