Název v původním jazyce

Chlorine in the Forest Ecosystem (a Radiotracer Study)

Popis výsledku v původním jazyce

In nature, chlorine does not occur only as chloride or bound in substances of anthropogenic origin in the polluted environment but also in many hundreds of compounds of natural origin. Chloride deposited in the forest ecosystem from the atmosphere reactswith soil organic matter (SOM) under the mediation of enzymes or microorganisms, and chlorine becomes chemically bound, forming chloroacetic acids (CAA), chloroform, other aliphatic and aromatic substances and chlorinated humic substances. Chloride, towhich Norway spruce is sensitive, is thus to a greater part blocked (organochlorines even prevail over chloride in soil) and chlorine participates in SOM degradation leading to smaller substances of SOM decay and finally to their mineralization. The aimof the investigations was to elucidate the uptake, effects and fate of phytotoxic trichloroacetic acid (TCA) in Norway spruce, to adress the role of CAA, and finally the global role of chlorine in forest ecosystems.
