Results and discussion
Any other information on results incl. tables
In 1976, vegetation in the locale of bromine production from brine extraction in the El Dorado-Magnolia, Arkansas, USA was severely affected. The first noted manifestation of a problem was damage to coniferous trees near the bromine production sites. Needle tip necrosis after 13 to 14 month and 1 to 2 month exposure time was evident within a 3 mile radius of all bromine facilities sampled in the area. At distances further from the plants (3.5 to 12 miles, tip damage was sporadic, vaying from tree to tree and not evident on 1 to 2 month exposure needles. The foliage burn and death of trees within 0.5 to 1 mile of each plant site was extreme. Conifers were decidedly more susceptible to bromine emissions than were broadleaf trees, shrubs and grasses. Chlorophyll (a and b) levels were greatly reduced in the conifer trees surrounding the bromine plants.
Applicant's summary and conclusion
- Conclusions:
- Exposure to bromine vapors is harmful to terrestrial plants, with conifers more susceptible than broadleaf trees, shrubs and grasses. Needle tip necrosis was a first manifestation near bromine production from brine extraction.
