Degradation of endosulfan residues was investigated in carnation plants cultivated in a greenhouse and in carnation plant byproducts used for animal feeds. The byproducts were stored under three different environmental conditions: non washed and exposed to open air (group A), washed and exposed to open air (group B), and non washed and placed in an enclosed container (group C). Byproduct stored in an enclosed container had longer half lives for both total endosulfan and its isomers than did other groups. Higher rates of degradation were measured in the greenhouse cultivated plants. Endosulfan II half lives were greater than those for endosulfan I in all groups studied. Compared to the stored byproduct groups, only greenhouse carnation plants had endosulfan residue levels below the maximum residue levels established for vegetables in the U.S.A. and the European Union during the 49 day trial.
