Abstract

In the current study, an intraperitoneal injection containing the same concentration of MeHg and HgCl2 was administered in Hoplias malabaricus, after 96 hours fish were anesthetized and the muscle tissue were removed. A significant inhibition of the ChE was observed the fish exposed to MeHg, compared to control. The present work demonstrates that ChE is an effective biomarker in fish exposed via intraperitoneal injection to the organic forms of mercury.
甲基汞和氯化汞暴露鱼的胆碱酯酶活性
在本研究中,将含有相同浓度的MeHg和HgCl2的水注入马齿虎(Hoplias malabaricus)腹腔注射,96小时后将鱼麻醉并去除肌肉组织。与对照组相比,暴露于甲基汞的鱼对ChE有明显的抑制作用。目前的研究表明,在通过腹腔注射暴露于有机形式汞的鱼类中,ChE是一种有效的生物标志物。
