Persistenz von Atrazin und seiner Metaboliten im Boden nach einmaliger Herbizidanwendung

Persistance of atrazine and its metabolites in soil after a single herbicide application The breakdown of atrazine in soil was investigated under field conditions. In spring 1973 the soil was treated with ¹⁴C ringlabeled atrazine. In summer 1981 soil samples were collected and analysed. The investigated soil still contained about 83% from the initial ¹⁴C activity. From this only 40% could be extracted. Besides traces of atrazine were further identified six metabolites which originated from the parent compound through N-dealkylation and hydrolysis.
