Atmospheric deposition will have been the major source of PCDD/Fs to the site over this time. PCDD/Fs were present in all the samples, and concentrations started to increase around the turn of the century, rising from 31 to 92 ng of ∑PCDD/Fs (kg of soil)−1 between 1893 and 1986. Unwashed bulked herbage samples from 1960–1970 and the 1980s contained 96 and 85 ng of ∑PCDD/F kg−1 respectively, compared to 12 ng of ∑PCDD/F kg−1 in a sample from 1880–1990. Average ∑PCDD/F net rates of increase in the soil over the last century were calculated as ca. 190 ng m−2 year−1. It is suggested that the increases in soil and herbage PCDD/Fs observed this century at Rothamsted are representative of those likely for agricultural systems in many industrialized regions. The possible changing sources of PCDD/Fs to the environment are discussed in the context of the concentration trends and congener-specific observations.",
