Methoxychlor (1,1,1-Trichloro-2,2-bis-|p-methoxyphenyl Jethane) 
Treatment of cows with methoxychlor apparently does not give rise to 
any residues in the milk. In other studies some metabolites have been 
isolated; however, none have been identified (285, 641, 859, 1179). 
After prolonged incubation of methoxychlor with Aerobacter aerogenes, 
some of the olefin and the reductively dechlorinated pesticide were 
observed (974). 
Methoxychlor was irradiated with high intensity ultraviolet energy 
between2200 and 3300 A. Dechlorination and cleavage occurred. Those 
compounds identified were: methoxyphenol; methylanisole; methoxychlor-DDE; 
1,1,4,4-tetrakis (p-methoxyphenyl)-2,3-dichloro-2-butene; 1,1,4,4-tetrakis 
(p-methoxyphenyl)-1,2,3-butatriene; p,p'-dimethoxybenzophenone (1762). 
2-Methoxy-3,6-Dichlorobenzoic Acid 
This compound is rapidly metabolized by wheat and bluegrass. One metab- 
olite has been identified as 3,6-dichlorosalicylic acid. The other metab- 
olite, representing 90% of the herbicide and believed to be a hydroxylated 
compound, has not been identified (1029).
