人尿中镉的含量可以反映近期镉接触情况和一定程度上反映体内镉负荷,特别是肾内镉水平。为镉中毒的诊断和治疗提供参考数据,同时也可作为评价环境中镉污染的指标。尿镉的测定方法中石墨炉原子吸收光谱法是目前使用最多的方法,它具有灵敏度高,准确性好的特点,但由于尿样基体复杂,直接测定干扰较大。国家卫生行业标准检测方法《尿中镉的石墨炉原子吸收光谱测定方法》[1]中,采用无镉正常人尿配制标准系列
Human urine cadmium content can reflect the recent exposure to cadmium and to some extent reflect the body’s cadmium load, especially in the kidney cadmium levels. Provide reference data for the diagnosis and treatment of cadmium poisoning, but also can be used as an indicator of cadmium pollution in the environment. Determination of urinary cadmium graphite furnace atomic absorption spectrometry method is currently the most used method, which has the characteristics of high sensitivity, good accuracy, but because of the complex matrix of urine samples, direct measurement of interference. National Health Industry Standard Detection Method “Determination of urinary cadmium graphite furnace atomic absorption spectrometry method” [1], the use of cadmium-free normal urine preparation standard series
