Abstract
Rhizon samplers have been used for several years for pore water extraction from soils (e.g. Knight et al. in Environ Pollut 99:293-298, 1998; Tye et al. in Geochim Cosmochim Acta 67:375-385, 2003; Sigfusson et al. in Sci Total Environ 369:203-219, 2006). With a few exceptions (e.g. Song et al. in Chemosphere 50:711-715, 2003; Seeberg-Elverfeldt et al. in Limnol Oceanogr Methods 3:361-371, 2005), they are rarely used for the extraction of pore water from sediments. The current study highlights the advantages and disadvantages of Rhizon samplers and outlines a simple, but effective method for pore water collection from lacustrine and estuarine sediment cores. This method can be used in the field or laboratory and does not require the use of a glove box to prevent change in pore water redox status. [PUBLICATION ABSTRACT]
