title: Studies of the movement and the formation of bound residues of atrazine, of its chlorinated derivatives, and of hydroxyatrazine in soil using 14C ring-labeled compounds under outdoor conditions.
abstract: Using unperturbed-structure soil columns, placed under field conditions for a 1-year period, we have evaluated the possibilities of penetration into the soil of various 14C ring-labeled s-triazinic compounds: atrazine, chlorinated derivatives, and hydroxyatrazine. We have simultaneously examined the possibilities of formation of bound residues for each of the compounds. 2-Cl-4,6-Diaminoatrazine appears to be the product most apt to form bound residues but this reaction is paralleled by a rapid loss of total residues. On the other hand, hydroxyatrazine is a strongly adsorbed product which is lost from the soil into the atmosphere only slowly and forms practically no bound residues.
