A Chlorine-36 and Carbon-14 Study of the Role of Chlorine in the Forest Ecosystem
Original language description
Radioisotopes carbon 14 and chlorine 36 were used to elucidate the environmental role of trichloroacetic acid (TCA) formerly taken to be a herbicide and a secondary air pollutant with phytotoxic effects. However, use of 14C-labeling posed again known analytical problems, especially in TCA extraction from the sample matrix. Therefore--after evaluation of available methods--a new procedure using decarboxylation of [1,2-14C]TCA combined with extraction of the resultant 14C-chloroform with a non-polar solvent and its subsequent radiometric measurement was developed. The method solves previous difficulties and permits an easy determination of amounts between 0.4 and 20 kBq (10 - 500 ng g(-1)) of carrier-less [1,2-14C]TCA in samples from environmental investigations. The procedure is, however, not suitable for direct [36Cl]TCA determination in chlorination studies with 36Cl. Because TCA might be microbially degraded in soil during extraction and sample storage and its extraction from soil or

Studie role chloru v lesním ekosystému za užití chloru 36 a uhlíku 14
Czech description
V článku je přehledně ukázána role chloru v lesním ekosystému. Chlorid není inertní, ale reaguje především za účasti mikroorganismů s půdní organickou hmotou za vzniku chlorovaných látek, kupř. chloroctových kyselin (CAA). Je presentován jejich vznik v lesní půdě spolu s jejich mikrobiální degradací, CAA tedy představují degradační půdní intermediáty. V lesní půdě dochází rovněž k chloraci fulvokyselin a dalších huminových látek i jejich dehalogenaci.
