Metabolic fate and distribution of [{sup 14}C]1,3-dichloropropene in carrot, lettuce, radish, tomato, and wheat
- North American Environmental Chemistry Lab., Indianapolis, IN (United States); and others
This study examined the nature of the radioactive residue in carrot, lettuce, radish, tomato, and wheat grown in soil treated with uniformly {sup 14}C-labeled cis- and trans-1,3-dichloropropene (1,3-D). Each crop was grown in soil treated at or above the maximum use rate. Carrot root and top, lettuce, radish root and top, tomato fruit and vine, and wheat forage, straw and grain were harvested, processed, and analyzed. The {sup 14}C residues were subjected to sequential extraction with diethyl ether and aqueous acetonitrile. The residues that remained were subjected to extraction, fractionation, and hydrolysis with buffer, enzymes, acid, alkali, and strong oxidizing agents. Analyses of the solubilized residues demonstrated that no detectable parent, 1,3-D, or the putative metabolites 3-chloroallyl alcohol and 3-chloroacrylic acid were present. The components of the extractable residue included most major plant constituents (i.e., protein, pigments, organic acids, sucrose, cellulose, and lignin). Thus, natural incorporation of the {sup 14}C-label into natural plant biochemicals is demonstrated.
