Atrazine [2-Chloro-4-ethylamino-6-isopropylamino-s-triazine ] 
Feeding studies with atrazine in rats indicated 20 metabolites (73). 
In other feeding studies with rats and rabbits, dealkylation was observed. 
Metabolites were isolated and identified (See table 1). In addition to 
the tabulated metabolites, rabbits also excreted N-(2-chloro-—4-amino~s- 
triazinyl-6) glucoside (133). In a goat and sheep, the ring in labeled 
atrazine was not metabolized; the side chain was metabolized (72).

cl4_atrazine was applied to susceptible and resistant plants. These 
studies showed that all test plants converted some atrazine to hydroxy- 
atrazine and that the amount was related somewhat to resistance (493, 1079, 
1080, 1224). Degradation of Cl4-ring-labeled atrazine to cl4Q5 was not a 
Significant process in plants (349). Hydroxyatrazine was also metabolized 
readily by oats (493).
