摘　　要：亚硝酸盐是水产养殖系统中一种潜在的污染物,淡水鱼类通过鳃主动吸收亚硝酸盐,导致体内亚硝酸盐的浓度过高。海水鱼类对亚硝酸盐的敏感性较低,但仍可以通过肠和鳃吸收亚硝酸盐。影响亚硝酸盐在体内蓄积的因素很多,文章就亚硝酸盐在水生动物体内的吸收及蓄积的影响因素这2个方面进行了论述。Nitrite is a potential pollutant in aquatic culture systems. Freshwater fishes actively take up nitrite across the gills, leading to high concentrations accumulated within body. Marine fishes are less susceptible but do take up nitrite across intestine and gills. Many factors carl influence nitrite accumulation. This paper gave a discussion about nitrite uptake mechanism and the influencing factors of accumulation in aquatic animals.
