Field calibration of polyurethane foam (PUF) disk passive air samplers for PCBs and OC pesticides

Assessing indoor air exposures using passive sampling with bioanalytical methods for estrogenicity and aryl hydrocarbon receptor activity

“…PCB 30 (2,4,6-trichlorobiphenyl) was the only PRC with sufficient loss in both locations and was therefore used as the indicator PRC for determining sampling rates for both indoor (1.3 m 3 day −1 ) and outdoor (4.1 m 3 day −1 ) locations. These in situ PCB 30-based sampling rates show good agreement with the relative magnitude of indoor [35] and outdoor [53] sampling rates measured previously for SVOCs. In addition, the in situ PRC-derived outdoor estimate approximates the sampling rate range (3.5–4 m 3 day −1 ) typically assumed in ambient monitoring studies for different classes of SVOCs, including PAHs [54–57].…”

Assessing Polycyclic Aromatic Hydrocarbons (PAHs) using passive air sampling in the atmosphere of one of the most wood-smoke-polluted cities in Chile: The case study of Temuco

“…Previous studies have demonstrated that PUF disk samplers capture both lower molecular weight (gas-phase) and high molecular weight (particle-phase) PAHs; however, some differences have been reported in sampling efficiency for gas-versus particle-phase PAHs (Chaemfa et al, 2008;Klanova et al, 2008;Harner et al, 2013;Bohlin et al, 2014). Even though it contributes in a small way to total PAHs in air, the particle-phase component of PAHs is important as most of the toxic burden of PAHs (carcinogenicity) is associated with the higher molecular weight compounds.…”

Field calibration of low density polyethylene passive samplers for gaseous POPs

“…Most monitoring programs still rely on active sampling for measuring atmospheric POPs. Yet high-volume samplers need maintenance, a power supply and a trained operator, and the sampling unit itself is bulky making it inappropriate for usage in remote areas [1][2][3] . They are also relatively expensive, which limits their applicability in large scale sampling campaigns where concurrent samples are collected 1,4 .…”

“…Semipermeable membrane devices (SPMDs) were first demonstrated to be a good passive sampling medium 12,14,16 . Polyurethane foam (PUF) disks were then introduced and are currently the most widely used passive samplers for monitoring atmospheric POPs 2,3,15,17,18 . XAD-2 resin passive samplers were also introduced lately and were used for monitoring atmospheric concentrations of organochlorine pesticides (OCPs) 1,19 .…”
