“…Furthermore, toxicity test results for PS 7-and 10-day samples were considerably lower than those for the GS samples. These findings are consistent with those of Tan et al [11], who studied the estrogenic effect of grab samples and passive sampler extracts of different matrices of wastewater treatment plants. The authors found that the estrogenic activity obtained using passive sampler extracts was lower than that obtained using grab samples, mainly due to biofouling.…”

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.

“…Tan et al (2007) studied the removal of 15 EDCs (hormones, alkylphenols, and phthalate esters) in WWTPs using conventional activated sludge or biological nutrient removal processes from Australia and found the removal efficiency of EDCs ranged from 80 to[99 %, whereas low concentrations of EDCs can still be detected in WWTP effluent. Nakada et al (2007) investigated the removal of phenolic EDCs and natural estrogens and found that ozonation contributed substantially to overall removal and that a combination of ozonation and sand filtration with activated sludge treatment can remove [80 % of all target compounds.…”

Occurrence of five endocrine-disrupting chemicals (EDCs)-bisphenol-A (BPA), triclosan (TCS), 17a-ethinyl estradiol (EE2), benzophenone-3, and 4-methylbenzylidene camphor-were monitored in East Lake, the largest urban lake in China. Other than EE2, all selected EDCs were detected at least once in the lake water with concentrations B89.1 ng/L. EDCs were detected with greater occurrence in spring than in other seasons. In lake sediment, TCS was detected at the greatest concentration (30.9 ng g -1 ), whereas BPA and EE2 were not detected. Spatial distribution of the EDCs in the lake water and the lake sediment showed similar patterns, and greater EDC residuals were found from those sites with known wastewater input. The linear adsorption coefficients (K d ) varied from 17.9 to 1,017 L kg -1 and were related to the octanolwater partition coefficient (K ow ) values of the compounds. Photodegradation was a major process removing the EDCs from the lake water, and the presence of dissolved organic material and NO 3 -in the lake water can accelerate the photodegradation process. Degradation of the EDCs in the lake sediment was relatively slow and occurred mainly due to the microbial processes. All compounds were found more persistent under anoxic conditions than under oxic conditions.

“…Examples of other passive sampler configurations are solid-phase microextraction fibers [5], polymer-coated glass systems [6], polyurethane foam disks [7], and various single-phase polymeric materials, including those identified above [1,8,9]. A wide array of compounds may be accumulated, including hydrocarbons and halogenated hydrocarbons, such as polyaromatic hydrocarbons, polychlorinated biphenyls and polybrominated diphenyl ethers [3,10], and endocrine disruptors [11], together with various pesticides and herbicides [12,13].…”

Abstract-Passive samplers are an important and versatile adjunct to active sampling methods for air and water. The underlying theory is increasingly mature but is often based on the assumption of constant concentrations with time in the ambient fluid. This theoretical work details the passive sampler response to possible environmental situations in which ambient concentrations vary linearly with time, decrease exponentially with time, constitute a pulsed event, or oscillate regularly with time. The modeled shape of sampler response curve with time is characteristic and can be used to determine how fluid concentrations have changed with time. The sampler elimination rate constant is shown to be crucial in governing sampler response. Thus, by using performance reference compounds and under certain conditions, information from the sampler response can in theory be used to derive specific details of the temporal variation of the contaminant in the ambient fluid. For example, data captured by a passive sampler can be used to characterize a contamination pulse.
