“…Taking the above-mentioned sampling techniques and their shortcomings into account, an integrated passive sampler with multiple sorbent-receiving phases currently offers the best scheme for monitoring and sampling runoff transport of both polar and non-polar compounds that contain P. To determine the fluxes of P in both solute forms and suspended particulates, deployment of a flow meter at the sampling location is strongly recommended. [76]).…”

Although phosphorus (P) is an essential nutrient for biological productivity, it can cause freshwater degradation when present at fairly low concentrations. Monitoring studies using continuous sampling is crucial for documenting P dynamics in freshwater ecosystems and to reduce the risk of eutrophication. Despite literature updates of developments of the analytical methods for measurement of P species in natural waters, there has been no comprehensive review addressing freshwater sample collection, sample preparation, and sample treatment to fractionate and characterize different forms of P. Therefore, this paper aims to elaborate the different techniques for freshwater sampling and to introduce alternative laboratory methods for sample preservation and P fractionation. The advantages and disadvantages of various sampling techniques, including the traditional manual and the recently developed automatic and passive methods, are presented to highlight the importance of collecting representative freshwater samples. Furthermore, we provide suggestions for sample pretreatment, including filtration, transportation, and storage steps to minimize microbial activity and to maximize the accuracy of measurement of various P fractions. Finally, the most common laboratory methods to measure dissolved and particulate as well as the organic and inorganic freshwater P fractions are efficiently provided. Using this guide, a comprehensive monitoring program of P dynamics in freshwater ecosystems can be developed and applied to improve water quality, particularly of P-rich freshwaters.

“…Four designs of passive samplers are frequently used to monitor semi-polar and polar pollutants in water namely: organic-diffusive gradient in thin film (o-DGT), polar organic chemical integrative samplers (POCIS), devices with granular activated carbon receiving phases [8], and Empore™ disk (ED)-based samplers such as the Chemcatcher ® [7,9]. o-DGT is generally composed of a limiting diffusion membrane, a thick diffusion hydrogel layer and a receiving phase.…”

“…Four studies reported the use of POCIS to sequester pollutants in GW [11][12][13][14]. Based on the use of hydrophilic-lipophilic balance (HLB) solid-phase sorbent, POCIS can sequester molecules covering a large range of polarity [9]. However, the loose sorbent can move during deployment and this can lead to nonreproducible data as sampler's active sampling surface area can differ over time [7].…”

This study describes the development of a novel Empore™ disk-based passive sampler specially adapted to groundwater monitoring. The sampler was calibrated in the laboratory using conditions that corresponded to groundwater (i.e. matrix medium, water temperature, flow rate and water flow across the disks). The retention and elution performance for sixteen semi-polar and polar pollutants on the Empore™ disk (47 mm diameter, SDB-XC) was evaluated. Recoveries were ~ 80% for the majority of compounds. Sampler uptake kinetics were measured over fourteen days at three concentrations (10, 100 and 500 ng L-1) and the sampling rate (RS) calculated for four compounds. There was no influence of concentration of the test analyte on the uptake profile; with mean RS varying between 0.018 ± 0.007 L day-1 and 0.047 ± 0.001 L day-1. Passive samplers were deployed in twelve characterized groundwater wells near Lyon (France). Atrazine, atrazine-desethyl and diuron were the main pollutants found with a maximum time-weighted concentration of 61, 62and 127 ng L-1 respectively.

“…This procedure is routinely applied by water supply companies as part of their regulatory monitoring programmes. The method is low-cost, but has some limitations (Gong et al 2018 ). For example, collected samples often require pre-concentration prior to analysis, and this can be time consuming; the concentrations obtained can be misrepresentative especially where there are sporadic inputs of pollutants into the aquatic environment and the response time is slow (Rabiet et al 2010 ).…”

Comparison of different monitoring methods for the measurement of metaldehyde in surface waters

Metaldehyde is recognised as an emerging contaminant. It is a powerful molluscicide and is the active compound in many types of slug pellets used for the protection of crops. The application of pellets to land generally takes place between August and December when slugs thrive. Due to its high use and physico-chemical properties, metaldehyde can be present in the aquatic environment at concentrations above the EU Drinking Water Directive limit of 100 ng L−1 for a single pesticide. Such high concentrations are problematic when these waters are used in the production of drinking water. Being able to effectively monitor this pollutant of concern is important. We compared four different monitoring techniques (spot and automated bottle sampling, on-line gas chromatography/mass spectrometry (GC/MS) and passive sampling) to estimate the concentration of metaldehyde. Trials were undertaken in the Mimmshall Brook catchment (Hertfordshire, UK) and in a feed in a drinking water treatment plant for differing periods between 17th October and 31st December 2017. This period coincided with the agricultural application of metaldehyde. Overall, there was a good agreement between the concentrations measured by the four techniques, each providing complementary information. The highest resolution data was obtained using the on-line GC/MS. During the study, there was a large exceedance (500 ng L−1) of metaldehyde that entered the treatment plant; but this was not related to rainfall in the area. Each monitoring method had its own advantages and disadvantages for monitoring investigations, particularly in terms of cost and turn-a-round time of data.Electronic supplementary materialThe online version of this article (10.1007/s10661-019-7221-x) contains supplementary material, which is available to authorized users.
