Abstract:
This paper presents an overview of the literature on concentrations and mechanisms for the uptake (and emission) of polychlorinated biphenyls (PCBs) in grass samples. Numerous experimental studies were performed to determine the properties of PCBs and dl-PCBs. Currently available data with respect to e.g. vapor pressure, solubility, Henry’s Law Constants or lifetimes in compartments are judged to be sufficient to assess the uptake and distribution in plant surfaces, at least as input parameters in box models. Soil is the most important sink for PCBs and the influence of carbon on the sink-strength is known. Only a few data exist about the emission of PCBs from soil surfaces with a consecutive uptake into the plant surface, although assumed to be important. Root-uptake into the plant system is not important (only important for highly contaminated soils). The main path-way of PCBs into the plant surface is dry deposition from the gas phase and models are available to assess and to explain concentrations of PCBs in plant surfaces. A selective enrichment of dl-PCBs is not known. Numerous factors influencing the uptake and emission into and from plant surfaces of PCBs are not well known. Examples of these factors include cultivation practice and interaction with particles.
