Changes in the polynuclear aromatic hydrocarbon content of wheat grain and pasture grassland over the last century from one site in the U.K.

Abstract

Crops harvested and stored from two long-term agricultural experiments started in the 1840-1850s at Rothamsted Experimental Station (U.K.) have been analyzed for polynuclear aromatic hydrocarbons (PAHs) because PAHs have increased four-to-five fold in the underlying 0-23 cm depth of soil over the last century due to atmospheric deposition. Bulked samples of… (More)
