“…In seawater polar sampler devices have been used in ecologically sensitive environments, such as offshore reefs, to gain a better understanding of the effects of the run-off pollutants, such as polar herbicides, on delicate marine species. Solvent extracts of the receiving phase have been used in short-term bioassay tests to gain a further understanding of the toxicological relevance of individual fractions of the complex mixture of sequestered pollutants (Shaw et al 2009). Different PSs (polar and nonpolar) proved to be sensitive tools capable of capturing a broad array of applied pesticides relevant to the Great Barrier Reef environment and provide the basis of a holistic approach to monitoring of land-sourced pesticides (Shaw et al 2010).…”

Until now, water quality monitoring has relied on spot sampling followed by instrumental analytical measurements to determine pollutant concentrations. Despite a number of advantages, this procedure has considerable limitations in terms of temporal and spatial resolution. The passive sampling techniques, which basically consist of concentrating substances on a submerged device for a given period and analysing accumulated substances, should improve the monitoring practices by simplifying analytical issues (lower detection limits, analysis in a simpler matrix) and allowing time integration of the contamination. The performance and potential applications of passive sampling for water quality monitoring in coastal and marine environments are described.

The responses of aquatic organisms to chronic exposure to environmental concentrations of toxicants, often found in mixtures, are poorly documented. Here passive sampler extracts were used in experimental contamination of laboratory channels, to investigate their effects on natural biofilm communities. A realistic mixture of pesticides extracted from Polar Organic Chemical Integrative Samplers was used to expose biofilms in laboratory channels to total pesticide concentrations averaging 0.5 ± 0.1 μg l⁻¹. The level of exposure was representative of field conditions in terms of relative proportions of the substances but the exposure concentration was not maintained (decreasing concentrations between contamination occasions). The impact on the structural as well as the functional characteristics of the autotrophic and heterotrophic components was determined, using biofilm grown in uncontaminated conditions (reference site) and in sites exposed to pesticides (contaminated site). The exposure imposed did not significantly modify the structure or functions of reference biofilms, nor did it modify tolerance as measured by mixture EC₅₀ (EC₅₀ mix). In contrast, the communities from the more contaminated downstream section lost tolerance following decreased dose exposure, but community composition remained fairly stable. Overall, these results indicate that low levels of contamination did not lead to strong changes in community structure, and 14-day changes in tolerance seemed to depend mainly on physiological adaptation, suggesting that other environmental factors or longer-lasting processes prevailed. This study reports the first attempt to use passive sampler extracts as a realistic composite contaminant for experimental exposure of biofilms, with promising perspectives in further ecotoxicology studies.

“…For passive sampling, we selected 47-mm SDB-RPS disks (3M, Saint Paul, USA), which contain a styrene-divinylbenzene copolymer that has been modified with sulfonic acid groups to make it hydrophilic and provide selectivity for polar organic chemicals. Shaw et al [4] reported that SDB-RPS disks are capable of sequestering a broad range of organic pollutants, however, the range of compounds sequestered has not been comprehensively identified.…”

The applicability of Empore TM styrene-divinylbenzene reverse-phase sulfonated (SDB-RPS) passive sampler disks for integrative sampling of organic chemicals in river water was investigated to evaluate toxicity levels via bioassay using larval medaka (Oryzias latipes). Those disks were deployed for periods of 1, 2, 3, 7, and 10 days (PS different period), and at 2-day intervals over the 10-day sampling period (PS interval). Six 10-L grab samples were collected at the same time as PS interval sampling, and thereafter concentrated using Sep-Pak ® Plus PS-2 cartridges (GS). Adsorbed chemicals were subsequently eluted from Sep-Pak cartridges and SDB-RPS disks and prepared for toxicity tests and gas chromatography/mass spectrometry analysis. Compared with all PS samples, GS samples showed strong toxicity results. None of the PS interval samples showed toxicity, even though the amount of adsorbed chemicals in the 2nd interval sample was higher than in PS 7-and 10-day samples, which showed toxicity. Furthermore, the PS 10-day sample contents were not equivalent to the accumulated amounts of adsorbed chemicals in PS interval samples. On the basis of these results, it is assumed that during long-term sampling, chemicals adsorbed on disks might be affected by desorption or decomposition, and that some might be converted to more toxic compounds.
