“…Passive sampling, whereby a material is directly deployed in wastewater to sorb the virus over time, may provide an inexpensive and practical alternative to autosampling ( Valenzuela et al, 2020 ). Liu et al (2020) used a Moore swab (i.e., pieces of gauzes) tied to a fishing line for surveillance of SARS-CoV-2.…”

In search of practical and affordable tools for wastewater-based surveillance of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), three independent field experiments were conducted using three passive sampler sorbents (electronegative membrane, cotton bud, and gauze) in Guelph, Ontario, Canada. Total daily cases during this study ranged from 2 to 17/100,000 people and 43/54 traditionally collected wastewater samples were positive for SARS-CoV-2 with mean detectable concentrations ranging from 8.4 to 1780 copies/ml. Viral levels on the passive samplers were assessed after 4, 8, 24, 48, 72, and 96 hrs of deployment in the wastewater and 43/54 membrane, 42/54 gauze, and 27/54 cotton bud samples were positive. A linear accumulation rate of SARS-CoV-2 on the membranes was observed up to 48 hours, suggesting the passive sampler could adequately reflect wastewater levels for up to two days of deployment. Due the variability in accumulation observed for the cotton buds and gauzes, and the pre-processing steps required for the gauzes, we recommend membrane filters as a simple cost-effective option for wastewater-based surveillance of SARS-CoV-2.

“…Other disadvantages to traditional detection methods include: 1) challenges of selectivity, wherein common co-existing but benign analytes can provide false positive signals using the pesticide sensor (Bexfield et al, 2020); 2) challenges in applicability for a pesticide life cycle, in which the sensor can detect the pesticide but not its decomposition products (Chen et al, 2019b); and 3) challenges in obtaining rapid results, due to the need for time-consuming separation and purification procedures, which are particularly critical in rapidly changing, real-world environments. Of note, many of these challenges can be addressed using on-site sampling followed by detailed inlaboratory analysis; such a strategy breaks down, however, for highly unstable pesticide and pesticide-related analytes (Valenzuela et al, 2020).…”

The detection of pesticides in real-world environments is a high priority for a broad range of applications, including in areas of public health, environmental remediation, and agricultural sustainability. While many methods for pesticide detection currently exist, the use of supramolecular fluorescence-based methods has significant practical advantages. Herein, we will review the use of fluorescence-based pesticide detection methods, with a particular focus on supramolecular chemistry-based methods. Illustrative examples that show how such methods have achieved success in real-world environments are also included, as are areas highlighted for future research and development.

“…Passive samplers have been widely employed to measure a large range of contaminants and can offer several advantages compared with traditional grab samples (Barcel o & Ruan, 2019;Greenwood et al, 2007). In site investigation work, passive sampling can reduce the labor costs and health and safety risk associated with sampling, amount of materials shipped for analysis, and investigation-derived waste generated (Valenzuela et al, 2020). Grab sampling provides water quality data at a specific time, but may not be representative of a time weighted average if transient variations in analyte concentration are missed.…”

Passive sampler designed for per‐ and polyfluoroalkyl substances using polymer‐modified organosilica adsorbent

et al. 2021

A passive sampler designed to measure per-and polyfluoroalkyl substances (PFAS) was evaluated to determine chemical uptake rates under a variety of conditions. The sampler design is simple and robust, using organosilica modified with cross-linked amine polymer in an high density polyethylene housing retained with polypropylene mesh. The addition of amine groups as a weak ionexchange resin in combination with Cu 2+ was designed to promote binding of short-chain PFAS. A five-fold improvement in perfluorobutanoic acid adsorption was measured when Cu 2+ was added to the polyethylenimine polymer. The samplers showed an integrated response to all analytes tested except for shortchain PFAS. Sampling rates of PFAS analytes from simulated groundwater were on average 10 mL/day at flow rates of 0.038-1.9 cm/min. Relatively low variability in sampling rate was observed over the range of laboratory tested conditions (representing common conditions in environmental waters) including elevated ionic strength, sulfate concentration, and humic acid content.
