Summary: The adsorption of atrazine and its transformation products, desisopropylatrazine (2‐chloro‐4‐ethylamino‐6‐amino‐l,3,5‐triazine), desethyl‐atrazine (2‐chloro‐4‐amino‐6‐isopropylamino‐l,3,5‐triazine) and hydroxyatrazine (2‐hydroxy‐4‐ethylamino‐6‐isopropylamino‐l,3,5‐triazine) to four top‐soils was measured. Adsorption coefficients decreased in the order hydroxy atrazine, atrazine, desisopropylatrazine, and desethyl‐atrazine: the distribution coefficient between organic matter and water (KOM) ranged from 40 to 100 dm3 kg−1 for atrazine, from 30 to 60 dm3 kg−1 for desisopropylatrazine, from 20 to 50 dm3 kg−1 for desethylatrazine and from 100 to 590 dm3 kg−1 for hydroxy atrazine. Data are discussed in the context of earlier literature.
