中华稻蝗(Oxya chinensis)对重金属镉的累积及排泄
A(c)cumulation and Excretion of Cadmium in Oxya chinensis Fed on Treated Diets with Cadmium
摘要
Abstract
In order to study the accumulation and excretion of heavy metal in insects, cadmium amounts in the whole body, midgut, feces, and exuviaes of Oxya chinensis fed on diets contaminated Cd were detected using an atomic absorption spectrometer. The results showed that the Cd accumulation characteristics in the whole body and midgut were similar. The accumulated Cd concentrations in the whole body and midgut rose with the increase of Cd content in the treated diets (wheat seedlings) and showed significant difference (P<0.05). Some of Cd in diets could be excreted through feces and exuviaes. The Cd excretion in the feces and exuviaes of 0. Chinensis fed on treated diets increased markedly comparing to the control treatment(P<0.05). There were statistically significant differences in Cd excretion between different treatments(P<0.05). There were significant dose-dependent relationships between Cd accumulated in the grasshopper, 0. Chinensis and Cd content in diets. The correlation coefficients were 0.977 for whole body, 0.920 for midgut, 0.967 for feces, and 0.840 for exuviaes, respectively. The results might provide insight into the dynamic variation of Cd accumulation and excretion in the grasshopper O. Chinensis.关键词
