The content of polychlorinated biphenyls in Mexican cereals and in their packaging materials was determined. All the samples had polychlorinated biphenyls. In all the food samples and in 73% of the packings, the concentrations of polychlorinated biphenyls exceeded the tolerance limits established by the U.S. Food and Drug Administration. A correlation was found between the values for polychlorinated biphenyls in the cereals and those in their packings, therefore, it is concluded that the main source of polychlorinated biphenyls in Mexican cereals is the transference of those present in the recycled paperboard used for the packings.
测定了墨西哥谷物及其包装材料中多氯联苯的含量。所有样品均含有多氯联苯。在所有食品样品以及73%的包装材料中，多氯联苯的浓度超过了美国食品药品监督管理局规定的耐受限度。发现谷物中的多氯联苯含量与包装材料中的多氯联苯含量之间存在相关性，因此得出结论，墨西哥谷物中多氯联苯的主要来源是用于包装的回收纸板中所含多氯联苯的转移。
