Abstract	Dibutyl phthalate (DBP) is a ubiquitous contaminant in the marine environment, and relatively little is known about the toxicological mechanisms of this compound at the metabolite level. In this study, marine gastropods (abalone) were exposed to DBP at environmentally relevant concentrations (2, 10, and 50 μg/L) for 30 days. The plasma metabolite profiles were determined at the 5th, 15th, and 30th. The major metabolite changes corresponding to DBP exposure were related to osmotic regulation, energy metabolism, and environmental stress, and the effects displayed a dose-dependent pattern. The most obvious change was the increase in the levels of intracellular metabolites (betaine, dimethylglycine, homarine, glutamine, and lactate) and tricarboxylic acid cycle intermediates. The results revealed that DBP may lead to abalone oxidative stress, lipid metabolism dysfunction, energy metabolism disturbance, and osmoregulation imbalance. These results would be helpful in better understanding the mechanisms of abalone response to DBP stress at the system level.
