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.

  • 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. (cs)
