“…The compound oxycarboxine was detected with 100% frequency (Table S5) and fenuron with 86% frequency in biota samples. Detection of banned pesticides has recently been reported with atrazine (banned since 2003) quantified in 63% of samples (Bernard et al, 2019). However, there is little occurrence data available for the banned pesticides detected here, but several banned pesticides including fenuron, atrazine and simazine have been found to occur in UK groundwaters (Forum, 2015).…”

“…However, there is little occurrence data available for the banned pesticides detected here, but several banned pesticides including fenuron, atrazine and simazine have been found to occur in UK groundwaters (Forum, 2015). The detection of these compounds in the environment might be explained by persistence and subsequent release of these compounds in sediments and/or soil (Bernard et al, 2019).…”

Multiple classes of environmental contaminants have been found in aquatic environments, globally. Understanding internalised concentrations in the organism could further improve the risk assessment process. The present study is concerned with the determination of several contaminant classes (107 compounds) in Gammarus pulex collected from 15 sites covering 5 river catchments across Suffolk, UK. Quantitative method performance was acceptable for 67 compounds including pharmaceuticals, pesticides, illicit drugs and drugs of abuse. A total of 56 compounds were detectable and ranged from

“…Most of them are based on simplified common assumptions: the existence of steady (or pseudo-stability) state, isotropic water sampler exchange kinetics, and the linear distribution curve. In those cases, the accumulation of analytes by passive samplers typically follow first-order The POCIS has been identified as an effective passive sampler for qualitative analysis of pesticides, pharmaceuticals, and perfluorinated compounds (PFCs), among others, in surface water, groundwater, and wastewater [8,[19][20][21][22]. It has the advantages of simple operation, low cost, no power demand, no maintenance requirement for isolation, and enrichment of organic compounds at low concentrations in a water environment.…”

As a passive sampling device, the polar organic chemical integrative sampler (POCIS) has the characteristics of simple operation, safety, and reliability for assessing the occurrence and risk of persistent and emerging trace organic pollutants. The POCIS, allowing for the determination of time-weighted average (TWA) concentration of polar organic chemicals, exhibits good application prospects in aquatic environments. Before deploying the device in water, the sampling rate (Rs), which is a key parameter for characterizing pollutant enrichment, should be determined and calibrated accurately. However, the Rs values strongly depend on experimental hydrodynamic conditions. This paper provides an overview of the current situation of the POCIS for environmental monitoring of organic pollutants in an aquatic system. The principle and theory of the POCIS are outlined. In particular, the effect factors such as the ambient conditions, pollutant properties, and device features on the Rs are analyzed in detail from aspects of impact dependence and mechanisms. The calibration methods of the Rs under laboratory and in situ conditions are summarized. This review offers supplementary information on comprehensive understanding of mechanism and application of the POCIS. Nevertheless, the Rs were impacted by a combined effect of solute–sorbent–membrane–solution, and the influence extent of each variable was still unclear. On this basis, the ongoing challenges are proposed for the future application of the POCIS in the actual environment, for instance, the need for this device to be improved in terms of quantitative methods for more accurate measurement of the Rs.

“…The physical soil properties are intimately related to the mobility and transport of solutes and contaminants, i.e., pesticides and trace metals. At the same time, the quality of freshwater is closely related to biogeochemical processes in soil and water environments in the Critical Zone [2,3]. Thus, interactions between soil and water are intimate and complex because of their heterogeneity, webs of interactions, wide-ranging scales, and self-organizing features [4].…”

The interactive pedological-hydrological processes and environmental sensitivity of a tropical isolated wetland in the Brazilian Cerrado

et al. 2021

In seasonal flooding isolated wetlands, the degree of wetness suggests a close synergy between soil processes, landscape evolution and hydrology along space and time. Until now, that subject has received insufficient attention despite natural wetlands supply essential environmental services to society and are surrounded by intensive agriculture that uses agrochemicals and fertilizers in their management. The objectives of this study were to propose an infiltration architecture model based on local surface and subsurface water-fluxes in isolated wetland embedded in lateritic plateau covered by savanna and qualify the environmental sensitivity as an area of aquifer recharge. Grain size, soil bulk density, and hydraulic conductivity were determined in five profiles in a soil catena. Unmanned Aerial Vehicle high-resolution images were obtained to generate a digital elevation model and discriminate areas with different vegetation, water accumulation, and environmental sensitivity. Electrical tomography was performed to unveil the soil architecture and infiltration. The soils (Plinthosols) developed on aquic conditions determine the linkage between the surface–subsurface hydrodynamics with the soil's physical properties. We have identified vertical and lateral water-flows in the soil architecture. Vertical flow occurs exclusively at the center, where the wetland is characterized as a recharge zone. Lateral flow towards the borders characterizes a discharge zone. The recharge zone is a depression surrounded by crops; therefore, it is a point of high environmental sensitivity. This hydrodynamic model is essential to support studies related to the dispersion of contaminants since soybean agriculture dominates the whole area of well-drained soils in the Brazilian Cerrado.
