DOCUMENT TYPE: Report CA Section: 4 (Toxicology) Section cross-reference(s): 5, 19 The behavior of chems. in 15 soils was studied in field expts. and in adsorption and desorption, percolation, and degrdn. expts. under defined lab conditions. Detailed data in 2,4,5-T [93-76-5], PCB [70424-69-0], picloram [1918-02-1], and LAS [25155-30-0] surfactant behavior in the soils studied, binding, uptake, and migration of heavy metal in and from the soils, behavior of volatile halogenic org. substances in soils with regard to ground water pollution, and non-effect levels of the chem. in microbial tests are detailed. Based on the data presented it is suggested that adsorption/desorption expts. may enable the primary prognosis of possible binding and movement of chems. in soils, but the action of chems. on organisms and their persistence in lab expts. should be parallelly carried out. Percolation expts. are not necessary for fast and slow immobilizing substances and field expts. with plant covered soils are not required for fast immobilizing chems. and for chems. acting weakly on organisms. Suggestions are made also as to the test soils and their choice.Except for chemicals metioned above, 74-85-1 and 7440-43-9 are also used. .
