Effects of Tributyltin (TBT)at Environment Concentrations on Bodyweight and Feeding Related Behaviors of Root Voles
摘要
Abstract
This study was conducted to investigate the effect of TBT at environment concentrations on the bodyweight and feeding related behaviors of root voles. The root voles of experimental group were administrated with 1μg/mL of TBT according to the dose of 5μL/(g·BW) once every 3 days by gavage, and those of control group were administrated with the same volume physiological saline. During the experiment period of 45 d, the body weight of the root voles was recorded and the amount of their food intake and drinking water (supply-surplus) were measured. Furthermore, the duration and frequency of feeding, drinking and movement were recorded with videotape. The results showed that only in a limited number of observation time points, the duration and frequency of feeding and drinking of male root voles in TBT exposure group were significantly higher than those in control group (P<0.05). However, there were not significant differences of the duration and frequency of feeding and drinking between female root voles in TBT exposure group and those in control group. The movement time of male root voles in the 3rd d after administrated with TBT was significantly more than that of the male root voles in control group (P<0.05), whereas the rest time was significantly less (P<0.05). With extension of the exposure time, none of significant differences of the movement and rest time were observed between the two groups. The influence of TBT exposure on the amount of food intake and drinking water and body weight of female root voles was not significant. It was indicated that the body weight of adult root voles was not significantly influenced by TBT exposure at environment concentrations, whereas the feeding related behaviors were partly influenced.关键词
