In Fiscal Years 1985/1986, the US Food and Drug Administration conducted a survey of cadmium, lead and other elements in fresh clams and oysters collected from US coastal areas in use for shellfish production. Shellfish were analysed for cadmium and lead by using a dry ash-anodic stripping voltammetric method. Other elements (aluminium, arsenic, beryllium, calcium, chromium, cobalt, copper, iron, magnesium, manganese, molybdenum, nickel, phosphorus, potassium, selenium, sodium, strontium, vanadium and zinc) were determined by using inductively coupled plasma-atomic emission spectrometry, direct current plasma-atomic emission spectrometry or hydride generation atomic absorption spectrometry. A total of 75 hardshell clam, 59 softshell clam, 104 Eastern oyster and 40 Pacific oyster samples were analysed for cadmium and lead. Average levels found were 0.09, 0.05, 0.51 and 1.1 mg/kg wet weight for cadmium and 0.24, 0.30, 0.11 and 0.06 mg/kg wet weight for lead in hardshell clams, softshell clams, Eastern oysters and Pacific oysters, respectively. The other 19 elements were determined in 10-104 samples of the four types of shellfish. These data provide baseline values for elements in clams and oysters harvested from US coastal waters.
在1985/1986财政年度，美国食品药品监督管理局对从美国沿海地区采集的用于贝类生产的新鲜蛤蜊和牡蛎中的镉、铅及其他元素进行了一项调查。采用干灰化阳极溶出伏安法分析贝类中的镉和铅。其他元素（铝、砷、铍、钙、铬、钴、铜、铁、镁、锰、钼、镍、磷、钾、硒、钠、锶、钒和锌）通过电感耦合等离子体原子发射光谱法、直流等离子体原子发射光谱法或氢化物发生原子吸收光谱法测定。共对75个硬壳蛤、59个软壳蛤、104个东部牡蛎和40个太平洋牡蛎样本进行了镉和铅分析。硬壳蛤、软壳蛤、东部牡蛎和太平洋牡蛎中镉的平均含量分别为0.09、0.05、0.51和1.1毫克/千克湿重，铅的平均含量分别为0.24、0.30、0.11和0.06毫克/千克湿重。对四种贝类的10 - 104个样本测定了其他19种元素。这些数据为从美国沿海水域收获的蛤蜊和牡蛎中的元素提供了基线值。
