摘要：

Field studies were conducted on PCDD/PCDF transfer from contaminated soils to lettuce, potato plants and hay. Contamination of crops by soil particles proved to be an important source of PCDD/PCDF in plants. When this pathway was excluded, there was little correlation between soil concentrations and plant concentrations of PCDD/PCDF. PCDD/PCDF concentrations only increased in unpeeled potato tubers with increasing levels of soil contamination. In shoots of plants air-plant transfer of PCDD/PCDF by far exceeds soil-plant transfer.
