重复部分的24小时饮食的110名成年人进行了分析铝，镉，铜，铅，锰，汞，锌，硝酸盐，亚硝酸盐和挥发性N-亚硝胺。铜的平均日摄入量（1.2毫克）仅为推荐值的50%左右;锰（3.3毫克）和锌（8.4毫克）的平均日摄入量相对于推荐量分别是足够的和边缘的。非必需元素Al、Cd、Hg和Pb的平均日摄入量分别为3.1 mg、0.01 mg、0.002 mg和0.034 mg。对于镉，这相当于每日可接受量的17%，铝，汞和铅分别为5%，5%和8%。自1976-1978年以来，铅的膳食摄入量减少了三分之一;其他六种元素的每日膳食摄入量与1976-1978年几乎相同。平均硝酸盐摄入量为52 ng NO3-/天，约为ADI的25%。只有16种饮食含有可测量的亚硝酸盐。最高日摄入量（0.7 mg NO2-）小于ADI的10%。挥发性N-亚硝胺检测在两个重复的饮食（NDMA和NPIP）。据估计，挥发性N-亚硝胺的每日膳食摄入量为约0.1 μ g或更少。
Duplicate portions of 24-hour diets of 110 adults have been analyzed for aluminium, cadmium, copper, lead, manganese, mercury, zinc, nitrate, nitrite and volatile N-nitrosamines. The mean daily intake of copper (1.2 mg) is only about 50% of recommended values; mena daily intakes for manganese (3.3 mg) and zinc (8.4 mg) are adequate and marginal respectively with respect to recommended amounts. For the non-essential elements Al, Cd, Hg and Pb, mean daily intakes of 3.1 mg, 0.01 mg, 0.002 mg and 0.034 mg were found, respectively. For Cd this amounts to 17% of the acceptable daily amount, for Al, Hg and Pb 5%, 5% and 8%, respectively. Since 1976-1978 the dietary intake of lead has been reduced by a factor three; for the other six elements daily dietary intakes are almost the same as in 1976-1978. Average nitrate intake was 52 ng NO3-/day, about 25% of the ADI. Only 16 diets contained a measurable amount of nitrite. The highest daily intake (0.7 mg NO2-) is less than 10% of the ADI. Volatile N-nitrosamines were detectable in two duplicate diets (NDMA and NPIP). It is estimated that the daily dietary intake of volatile N-nitrosamines is around 0.1 .mu.g or less.
