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.
This paper presents the framework within which simulation models are used in the Netherlands to evaluate (for registration purposes) the leaching of pesticide residues to groundwater. The Pesticide Leaching and Accumulation (PESTLA) model is used to determine those active ingredients and metabolites for which additional field experiments will be required to determine the actual risk of leaching. Furthermore, PESTLA is used to interpret results from field experiments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
