This paper reviews the concentrations of trichloroacetate (TCA) in the atmosphere–plant–soil system. Data originate mainly from Europe. The median TCA concentration in rainwater and canopy drip decreased until 1995. From then the median TCA conce

Since we demonstrated the natural formation of chloroform in soil, the question arose to which extent this contributes to the chloroform present in the atmosphere. Concentration gradients in soil air and atmospheric air of different forests were meas

The concentrations of trichloroacetic acid (TCAA) in soil and of chlorinated solvents in soil air from simultaneously taken samples from four sites are presented. The data show that there is a significant positive correlation between the concentratio

Since the ban on the use of trichloroacetic acid (TCAA) as a herbicide in several countries, TCAA is still found ubiquitously in the environment. The presence of TCAA nowadays is suggested to originate mainly from the atmospheric degradation of tetra

The natural formation of 4-MCP, 24/25- and 26-DCP, and 245-TrCP was detected in four selected areas of a rural Douglas fir forest where the humic layer was spiked in situ with a solution of Na[sup 37]Cl and covered by an enclosure, after 1 year of in

Chloroform production was detected in the headspace of pure cultures of the basidiomycetes Mycena metata and Peniophora pseudopini and the deuteromycete Caldariomyces fumago. The average production rates were in the range of 0.07–70 μg\l culture f

An AOX transport model is used to distinguish natural and anthropogenic sources of organohalogen compounds in river basins. Application of this model to AOX data of the river Rhine basin in the years 1986 to 1991 shows a constant natural AOX contribu
