Abstract

Low temperatures (10 +/- 1 degrees C) induce a rapid entry of cadmium into the body across the gills and gut; higher temperatures (20 +/- 1 degrees C) induce a medium and long term absorption and storage of the metal in the digestive gland and its long term accumulation in the exoskeleton. From a methodical point of view, electron microprobe appears more suitable than secondary ion emission microanalysis for the detection of cadmium.

摘要

低温(10±1摄氏度)促使镉迅速通过鳃和肠道进入体内;较高温度(20±1摄氏度)促使金属在消化腺中进行中长期吸收和储存,并在外骨骼中长期积累。从方法学角度来看,电子微探针在检测镉方面似乎比二次离子发射微分析法更为适用。
