Oxidative stress related enzymes in response to chromium (Ⅵ) toxicity in Oxya chinensis ( Orthoptera : Acridoidae)

The toxic effects of Cr（Vl） on antioxidant enzymes of Oxya chinensis（Orthoptera： Acridoidae） were determined. Changes in the activities of the antioxidant enzymes superoxide dismutase（SOD）, catalase（CAT）, and guaiacol peroxidase（GPx） were measured in O. chinensis insects injected with Cr（VI）. Fifth-nymphs of O. chinensis insects were injected with Cr（VI） with different concentrations （0, 75, 150, 225, 300, 375, 450 mg/kg of body weight）. The results showed that Cr（VI） led to the change of SOD, CAT, and GPx activities at different concentrations, which revealed that： （1） The oxidative stress of SOD increased with the increase of Cr （VI） concentration. （2） With the increase of Cr （VI） concentrations, CAT activities for females increased at lower concentrations, but decreased at higher concentration range, which indicated that antioxidant system of O. chinensis was not influenced by the presence of Cr （VI）. A very similar response to Cr（VI） effect for males indicated that Cr（VI） concentrations were not high enough to damage O. chinensis in terms of CAT. （3） The GPx activity for females increased in all treatments, which revealed that the damage power of Cr（VI） was increased with the increase of Cr（Vi） concentrations in terms of GPx, but the effect was not so remarkable. There was not a consistent trend of GPx activities for males in all treatments of Cr（VI）. Cr（VI）-induced changes in antioxidant enzymes were different for SOD, CAT and GPx, of which the tendency was that activities generally changed with increase of concentrations of Cr（VI） suggesting SOD, CAT, and GPx could serve as indices of oxidative stress to some extent.     

水体中价态铬的化学发光测定

洛粉化学发光法测定cr(Ⅵ)具有快速，方便的优点。该方法捡测限为0.08pbCr(Ⅵ)，线性范围宽。大量Ca(Ⅱ)、Mg(Ⅱ)可能产生千扰，可以用阳离子交换法消除。本法与鲁米诺化学发光法结合，可以测定水体中痕量的三价、六价铬。

红壤对铬（Ⅵ）吸附特性的研究

通过云南三类红壤对Ｃｒ（Ⅵ）吸附行为的研究，结果表明，红壤对Ｃｒ（Ⅵ）有明显的吸附作用，等温吸附曲线可以用Ｆｒｅｕｎｄｌｉｃｈ方程、Ｌａｎｇｍｕｉｒ方程和Ｔｅｍｋｉｎ方程描述，最大吸附量为红壤〉赤红壤〉砖龚壤。酸度、温度和有机质对红壤吸附Ｃｒ（Ⅵ）均有影响。低ｐＨ值时吸附量随ｐＨ值升高力吸增加，ｐＨ值超过某一限度，吸附量急剧下降，直至基本不吸附；温度低于４０℃时，吸附量随或高而减少，但温度高于４０
