Accumulative sampling of trace pesticides and other organics in surface water using xad‐4 resin

Abstract: XAD-4 resin accumulative sampling was tested as a means of on-site extraction of surface waters. Recoveries for most organochlorine, organophosphorus, organonitrogen, chlorophenol, and chlorophenoxy acid pesticides and related pollutants were acceptable (>50%) when spiked at the 10 and 0.1 ppb levels. Detection limits of 1-100 ppt were attainable for most compounds in river water, although lower levels required the use of an HPLC cleanup/fractionation step prior to those GC determinations using electroncapture… Show more

“…Accumulative samplers operate on the principle of mass transfer over time from an ambient fluid source (environmental phase) to an engineered sink (sampling phase) (Fowler, 1982; Woodrow et al, 1986). Mass transfer between the phases is regulated by advective and diffusive transport of the target compounds to and through the sampler.…”

“…Accumulative sampling follows a general trend in analytical chemistry towards techniques which sequester and pre-concentrate compounds of interest before analysis (Jolley, 1981; Murray, 1997) and may be contrasted with discrete (grab) sampling, which captures and removes an aliquot of the ambient fluid (Woodrow et al, 1986). Both equilibrium and integrative methods can provide pre-concentration by acting as a preferred phase for partitioning of the analyte.…”
