Phenanthrene sorption to soils and soil fractions was investigated using two contrasting soils with different clay mineral and organic carbon (OC) contents in an attempt to evaluate the contribution of each soil fraction to phenanthrene sorption and the applicability of the carbon-normalized distribution constant (K OC ) in soils. Sorbents were characterized using surface analysis, solid-state...
The abiotic desorption of p,p′-DDT from seven Chinese soils spiked with p,p′-DDT and the effects of oxalate at 0.001–0.1M and the root exudates of maize, wheat, and ryegrass were evaluated using batch experiments. Soil organic carbon played a predominant role in the retention of DDT. Oxalate significantly increased the desorption of p,p′-DDT, with the largest increments ranging from 11% to 54% for...
