Behavior of Sewage Sludge-Derived PAHs on Pasture

Behavior of Sewage Sludge-Derived PAHs on Pasture

A field experiment was set up to investigate the retention of PAHs by pasture grass following sludge application. In addition to information on compound-specific loss rates, the influence of meteorological variables and sludge−pasture contact time on the weathering process were investigated. The rat...

Zusammenfassung:A field experiment was set up to investigate the retention of PAHs by pasture grass following sludge application. In addition to information on compound-specific loss rates, the influence of meteorological variables and sludge−pasture contact time on the weathering process were investigated. The rates of loss were compound specific with half-lives ranging from
