Average pesticide residue levels were determined for the 17 main food groups in the average Spanish diet. Using these levels and the estimated average intake of these foods, authors computed an individual's average daily consumption of pesticides from each of these food groups and her/his total diet. Foods were acquired over a 1-year period from the market of Valencia, a city that gets supplies from an agricultural area where pesticide consumption is appreciably higher than that of the rest of the country. Thus average residue levels found must be higher than the national average. Except for fruits and vegetables, the different items composing each food group were sampled in proportion to the amount consumed in the average Spanish diet. Foods forming each group were homogenized into composite samples. All foods were analyzed raw. The most frequently detected pesticides were DDT and BHC. Malathion was detected at levels less than 0.10 ppm in some samples of vegetable oils, pears, and apples. DDT and BHC levels varied from undetectable to amounts less than 1.0 ppm. Highest levels were found in lard. An individual's average daily intake of pesticides was calculated to be 78 mug DDT, a sum which includes residues of o,p'-DDT, p,p'-DDT, and p,p'-DDE, and 13.8 mug gamma-BHC. These levels are much lower than the maximum acceptable daily limits established by the United Nations Food Agricultural Organization and World Health Organization.
测定了西班牙日常饮食中17种主要食物组的平均农药残留水平。利用这些水平以及这些食物的估计平均摄入量，作者计算了个体从这些食物组中每种食物以及其整个饮食中农药的平均每日摄入量。食物是在一年时间里从巴伦西亚市场获取的，该市的供应来自一个农药消费量明显高于该国其他地区的农业区。因此，所发现的平均残留水平必定高于全国平均水平。除水果和蔬菜外，构成每个食物组的不同项目按照西班牙日常饮食中的消费量比例进行采样。构成每个组的食物被均质化为复合样本。所有食物均进行生食分析。最常检测到的农药是滴滴涕和六六六。在一些植物油、梨和苹果样本中检测到的马拉硫磷水平低于0.10 ppm。滴滴涕和六六六的水平从检测不到到低于1.0 ppm不等。在猪油中发现的水平最高。个体农药的平均每日摄入量经计算为78微克滴滴涕，这一总量包括o,p'-滴滴涕、p,p'-滴滴涕和p,p'-滴滴滴的残留量，以及13.8微克γ-六六六。这些水平远低于联合国粮食及农业组织和世界卫生组织规定的每日最大可接受限量。
