从芬兰的8～11个屠宰场随机选取同一猪或牛的肌肉、肝和肾各100～200g,进行铅、镉、汞的浓度测定。用无焰原子吸收分光光度法测量铅和镉的浓度;用冷蒸汽原子吸收分光光度法测量汞的浓度。结果铅的平均湿重浓度在猪的肌肉、肝和肾中为15、38和41/μg/kg,在牛则为13、57和110μg/kg;镉的平均湿重浓度分别为1.5、28和170μg/kg(猪)及1.3、61和350μg/kg(牛);汞的平均湿重浓度在猪为11、
The concentrations of lead, cadmium and mercury were determined by randomly selecting 100 to 200 g of the muscle, liver and kidney of the same pig or cow from 8 to 11 slaughterhouses in Finland. The concentration of lead and cadmium was measured by flameless atomic absorption spectrophotometry; the concentration of mercury was measured by cold vapor atomic absorption spectrophotometry. Results The average wet weight of lead was 15, 38 and 41 μg / kg in pigs, liver and kidney, and 13, 57 and 110 μg / kg in cattle. The average wet weight of cadmium was 1.5 and 28 And 170 μg / kg (pigs) and 1.3, 61 and 350 μg / kg (cow) respectively; the average wet weight concentration of mercury was 11 for pigs,
