N2 - Soil profile samples collected from the same plot at Rothamsted Experimental Station in southeast England in 1893, 1944 and 1987 have been analysed for polynuclear aromatic hydrocarbons (PAHs).

Average rates of increase in the plough layer for individual PAHs in the Rothamsted plots over the century since c. 1890 vary between 0.01 and 0.67 mg m-2 year-1.
