Here, TCA fluxes through 22 in situ soil columns in a forest and moorland catchment and an agricultural grassland field were monitored every 2 weeks for several months either as controls or in TCA artificial dosing experiments (supplemented by laboratory experiments with radioactively-labelled TCA and with sterilized soil columns). The laboratory experiments showed that both the formation and degradation processes operate on time scales of up to a few days and appeared related more with biological rather than abiotic processes. Soil TCA activity was greater in more organic-rich forest soils, and there was strong correlation between TCA and soil biomass carbon content. Overall it appears that TCA soil processes exemplify the substantial natural biogeochemical cycling of chlorine within soils, independent of any anthropogenic chlorine flux.
