Description/Abstract

The effects of acidification and liming on the mobilization of benzo(a)pyrene (BaP) were studied in a long-term column experiment with a sandy topsoil spiked with this hydrophobic compound at a concentration of 100 mg kg-1. Soil acidification to pH 3.3 initially caused a decreased release of BaP, but in the course of the 14-months study, BaP-concentrations in the leachates surpassed control levels 10-15-fold. This is attributed to DOM-enhanced solubility of BaP, although no correlation with DOC-concentrations was found. Instead, increased DOM-sorptivity is attributed to the increases in DOM-aromaticity and DOM-size which occurs in response to decreasing Ca-concentrations and increasing pH in the solutions. A short term BaP-mobilization in the lime treatment is not related to these parameters but may indicate the participation of heavy metals in DOM-BaP-interactions.
