“…In this work, highly porous activated carbon was used instead. Activated carbon is well known to remove almost all organic compounds from aqueous solutions with a high efficiency 23‐26. We found that activated carbon can work as well as graphitized carbon black as the sorbent in SPE.…”

A rapid technique for the screening of trace compounds in water by combining solid-phase extraction (SPE) with activated carbon surface-assisted laser desorption/ionization (SALDI) time-of-flight mass spectrometry is demonstrated. Activated carbon is used both as the sorbent in SPE and as the solid in the SALDI matrix system. This eliminates the need for an SPE elution process. After the analytes have been adsorbed on the surfaces of the activated carbon during SPE extraction, the activated carbon is directly mixed with the SALDI liquid and mass spectrometric analysis is performed. Trace phenolic compounds in water were used to demonstrate the effectiveness of the method. The detection limit for these compounds is in the ppb to ppt range.

“…5,6 High preconcentration factors for nonpolar to medium polar analytes have been well-known for SPE methods for ∼20 years. SPE has been applied for nontarget analysis like surface water monitoring, 7,8 toxicity tracking procedures, [9][10][11] or, most regularly, analysis of compounds of special interest. Its drawbacks, however, have been rarely pointed out clearly.…”

Untreated and biologically cleaned industrial wastewaters contain huge amounts of both hydrophilic and hydrophobic compounds. Due to breakthrough effects, only a few percent of the dissolved organic carbon is usually extracted by solid-phase extraction methods. Methods for screening analysis have not faced that problem sufficiently yet. To extract more hydrophilic compounds, solid-phase sorbent characteristics had to be evaluated in this study. Recovery studies were carried out with 21 hydrophilic aromatics including carboxy acids, sulfonates, aldehydes, ketones, thiols, and phenols at a level of 1−2 μmol/L. Both silica gel based sorbents and polymeric materials were tested at neutral to acidic pH values and extraction volumes up to 200 mL. It was found that poly(styrene−divinylbenzene) sorbents are a powerful tool for the enrichment of hydrophilic aromatic substances. Most of the tested compounds could be extracted at recovery rates of >80%. The quantitative extraction of thiols as well as (aminohydroxy)disulfonic acids remains an unsolved problem. Finally, combination of different solid sorbents and pH changes is suggested for sequential extraction of heavily loaded industrial wastewaters. Advantages and limitations are discussed and an example of its usefulness is given.

“…The best way of approaching the problem of risk assessment is to use biological tests especially short-term bioassays on bacteria (Monarka et al, 2000). However, it has been known that such biological tests are dependent on the concentration techniques (Onodera et al, 1993;Umbuziro et al, 2004;Buschini et al, 2008).…”

-Amberlite XAD-2 resin extracts of river and drinking water sampled from the Northwest district of Chiba Prefecture in each month during the period from January to December 2008 were investigated to characterize and determine their mutagenic potentials and polycyclic aromatic hydrocarbon (PAH) levels. The extracts from the river water were shown to be mutagenic in Salmonella typhimurium TA98 (a flameshift mutagen) without S9 mix, with higher mutagenic responses in summer and early fall seasons. While the drinking water extracts exhibited weak mutagenicity in both the TA98 and TA100 strains (a base-pair substitution mutagen) without S9 mix, with high mutagenic responses in fall and early winter seasons. GC/MS determinations of the water concentrates showed some seasonal scatter in PAH levels in river water. In contrast, comparatively high concentrations of PAHs were observed for drinking water samples collected during warmer seasons. Statistical studies revealed that there is a lower correlation between the levels of flameshift mutagenicity and the concentrations of PAH in the river water concentrations, but a higher correlation between them in the drinking water samples.
