Effects of halone 1301 on Lepidium sativum, Petunia hybrida and Phaseolus vulgaris.
Chemosphere 41, 1603-1610 (2000)
Halone 1301 belongs to a group of widely used fire repellants. Although banned in several countries, the production has still not been discontinued, and thus hazards due to use or spill can be expected. The study reports on effects of the halone 1301 on three plant species frequently used for bioindication studies: Lepidium sativum (mouse-ear cress), Phaseolus vulgaris (bush bean) and Petunia hybrida. Plants were exposed to 1 ppbv of the gas in ambient air under controlled conditions for 18 days (L. sativum), and 45 days (P. vulgaris, P. hybrida), respectively. None of the plants showed visible stress symptoms. Chlorophylls in cress and petunia were unaffected whereas in beans significant changes of the photosynthetic pigments were observed. Photosynthesis and gas exchange of bean plants were monitored during the experiment, and a lowering of transpiration was noticed. In all investigated plants, protein contents declined significantly, but despite this reduction, activity of the glutathione S-transferases (GST) increased strongly in bean and petunia. The significance of this reaction as detoxification step is discussed.
