Lead and calcium nitrate in a potato base were fed to Porcellio scaber; three levels of each cation were used in a 3 factorial design experiment. The amounts accumulated were determined by atomic absorption spectrophotometric analysis of nitric acid digests of whole animals. Both cations increased markedly in the woodlice with increasing dosage and a clear correlation was found between the rates of uptake of the two.
将以马铃薯为基质的铅和硝酸钙喂给鼠妇;在一个三因素设计实验中,每种阳离子使用了三个水平。通过对整个动物的硝酸消化物进行原子吸收分光光度分析来测定积累量。随着剂量增加,两种阳离子在鼠妇体内的含量均显著增加,并且发现两者的摄取速率之间存在明显的相关性。
