The content of cadmium and lead was measured in vegetables, fruit, cereals and soil from areas exposed and non-exposed to industrial pollution and in vegetables and soil from greenhouses. The elements were measured after dry mineralization by atomic absorption spectrophotometry following extraction of complexes from APDS into the organic phase (MIBK). Lead and cadmium were determined in 482 samples of vegetables, 101 fruit samples, 132 cereal samples and 297 soil samples. In the vegetables from the areas not exposed to industrial pollution lead content was below the detectability range (< d.r.) to 576.1 micrograms/kg, and cadmium was from < d.r. to 73.5 micrograms/kg. In the vegetables from areas exposed to industrial pollution lead was from 9.3 to 1044.0 micrograms/kg and cadmium from < d.r. to 552.3 micrograms/kg and cadmium from 2.3 to 132.5 micrograms/kg. In the soil from greenhouses lead was found in amounts from 17.5 to 212.0 mg/kg of air dry mass (adm), and cadmium from 125 to 750 micrograms/kg of adm. In soil from vegetable gardens lead was from 3.3 to 15.3 mg/kg of adm., and cadmium from < d.r. to 385.0 mu/kg adm. In soil from orchards lead was from 2.8 to 141.3 mg/kg adm, and cadmium from < d.r. to 810.0 micrograms/kg adm. In the soil from fields of cereals lead was from 3.0 to 67.5 mg/kg amd, and cadmium from < d.r. to 295.0 micrograms/kg adm. In fruit lead was present in amounts from 12.8 to 144.0 micrograms/kg and cadmium from < d.r. to 42.0 micrograms/kg. In cereals lead was found in amounts from < d.r. to 760.0 micrograms/kg and cadmium from < d.r. to 200 micrograms/kg.
对来自工业污染暴露区和非暴露区的蔬菜、水果、谷物及土壤,以及温室中的蔬菜和土壤进行了镉和铅含量的测定。通过原子吸收分光光度法在干灰化后对元素进行测定,将络合物从APDS萃取到有机相(甲基异丁基酮)中。对482份蔬菜样品、101份水果样品、132份谷物样品和297份土壤样品中的铅和镉进行了测定。在未受工业污染地区的蔬菜中,铅含量低于检测范围(<d.r.)至576.1微克/千克,镉含量为<d.r.至73.5微克/千克。在受工业污染地区的蔬菜中,铅含量为9.3至1044.0微克/千克,镉含量为<d.r.至552.3微克/千克,以及镉含量为2.3至132.5微克/千克。在温室土壤中,发现铅含量为17.5至212.0毫克/千克风干质量(adm),镉含量为125至750微克/千克adm。在菜园土壤中,铅含量为3.3至15.3毫克/千克adm,镉含量为<d.r.至385.0微克/千克adm。在果园土壤中,铅含量为2.8至141.3毫克/千克adm,镉含量为<d.r.至810.0微克/千克adm。在谷物田土壤中,铅含量为3.0至67.5毫克/千克amd,镉含量为<d.r.至295.0微克/千克adm。在水果中,铅含量为12.8至144.0微克/千克,镉含量为<d.r.至42.0微克/千克。在谷物中,铅含量为<d.r.至760.0微克/千克,镉含量为<d.r.至200微克/千克。
