Monsanto produced two distinct variants of Aroclor 1254. The late-production variant resulted from a change in Monsanto's manufacturing process in the early 1970s. Previous literature had reported that the late-production variant was produced from 1974 to 1976, but subsequent work has identified a sample known to be obtained in 1972. In this paper, we present congener-specific PCB and PCDD/F data for this 1972 late-production sample, and a brief historical record of late-production Aroclor 1254.
孟山都生产了两种截然不同的 Aroclor 1254 变体。后期生产的变体是孟山都在 20 世纪 70 年代初改变其制造工艺的结果。之前的文献报道称,后期生产的变体是在 1974 年至 1976 年生产的,但随后的工作确定了一个已知在 1972 年获得的样本。在本文中,我们提供了该 1972 年后期生产样本的特定同系物 PCB 和 PCDD/F 数据,以及后期生产 Aroclor 1254 的简要历史记录。
