重金属镉和铬在中华稻蝗(Oxya chinensis)体内的组织分布
Cadmium and Chromium Accumulation in the Tissues of the Chinese Rice Grasshopper, Oxya chinensis
摘要
Abstract
In order to study the accumulation pattern of heavy metal in the Chinese rice grasshopper, Oxya chinensis, the grasshoppers were collected from Daixian County, Shanxi Province, China. The cadmium(Cd) and chromium(Cr) concentrations in their bodys were determined using atomic absorption spectrometry. The results showed that accumulation of Cd in 0. Chinensis were different in various parts of the insect. The order of Cd concentration in the female grasshoppers was midgut>hindgut>foregut>wings>head>ovary>legs>body wall; for males, the order was midgut>foregut>hindgut>legs>head>body wall and the accumulation of Cd in the wings and testis were not detected. The results indicated that the accumulation of Cd in the gut of 0. Chinensis were higher, and that in midgut was the highest, which showed significant difference compared to that of the other parts(P＜0.001). The Cd concentration in the midgut was 6.798 4 mg· kg-1 and 3.347 7 mg·kg-1 for female and male, respectively. The order of Cr concentration in the grasshoppers was midgut>legs>body wall>head>ovary>foregut>wings>hindgut for females and legs>body wall>midgut>head>foregut>testis>wings>hindgut for males. The results of the tests of between-subjects effect showed that the Cd and Cr accumulation in the rice grasshopper O. Chinensis was tissue-specific, and the accumulation characteristics between Cd and Cr were different.关键词
