Decontamination activity of ryegrass exudates towards bisphenol A in the absence and presence of dissolved natural organic matter.

Bisphenol A (BPA) is an endocrine disruptor compound widespread in terrestrial and aquatic systems of urbanized and industrialized regions. This study evaluated the capacity of ryegrass (Lolium perenne) aqueous exudates to degrade BPA at a concentration of 10 mg L(-1) both in the absence and in the presence of an organic fraction often coexisting with plant exudates, i.e.

Small scale variability of chlorinated POPs in the river Elbe floodplain soils (Germany).

The long-time use of persistent organic pollutants (POPs) led to a world-wide contamination of environmental compartments. Although, bans of numerous POPs reduced the POP input to rivers. Floodplain soils are still highly contaminated, because they are sinks for these compounds, which restrict their agricultural use.
