“…This could provide scientific explanations for fungal responses to multiple contaminants at the molecular level (Aydin et al 2017 ; Wang et al 2017 ). Further, to obtain high-resolution spatial distribution characteristics of toxic metals and reveal interface reaction processes of soil-metals-fungal interactions, new methods such as gradient diffusion film technology (DGT) combined with laser ablation-inductively coupled plasma mass spectrometry could be applied to analyze dynamic changes in toxic metal speciation at soil-microbe interfaces (Challis et al 2018 ; Feng et al 2016 ; Koppel et al 2020 ; Wang et al 2018 ). Such approaches will further clarify fungal transformation mechanisms in soil contaminated with petroleum hydrocarbons and toxic metals and may contribute to more effective strategies for fungal bioremediation.…”

Much research has been carried out on the bacterial bioremediation of soil contaminated with petroleum hydrocarbons and toxic metals but much less is known about the potential of fungi in sites that are co-contaminated with both classes of pollutants. This article documents the roles of fungi in soil polluted with both petroleum hydrocarbons and toxic metals as well as the mechanisms involved in the biotransformation of such substances. Soil characteristics (e.g., structural components, pH, and temperature) and intracellular or excreted extracellular enzymes and metabolites are crucial factors which affect the efficiency of combined pollutant transformations. At present, bioremediation of soil co-contaminated with petroleum hydrocarbons and toxic metals is mostly focused on the removal, detoxification, or degradation efficiency of single or composite pollutants of each type. Little research has been carried out on the metabolism of fungi in response to complex pollutant stress. To overcome current bottlenecks in understanding fungal bioremediation, the potential of new approaches, e.g., gradient diffusion film technology (DGT) and metabolomics, is also discussed. Key points • Fungi play important roles in soil co-contaminated with TPH and toxic metals. • Soil characteristics, enzymes, and metabolites are major factors in bioremediation. • DGT and metabolomics can be applied to overcome current bottlenecks.

“…The CMIP‐gel was immersed in a 20 mL mixed solution containing 0.2 mmol/L of norfloxacin, chloramphenicol, malachite green and CF for 1 h at room temperature. Binding selectivity (K) of the binding layer was obtained by the ratio of the mass of CF binding on the gel M (CF) to that of other compounds M (m) .

A technique of diffusive gradients in thin films with ciprofloxacin-molecularly imprinted polymers as the binding agent was developed for in situ selective sampling and measurement of ciprofloxacin in water. The ciprofloxacin uptake by the method increased linearly with time (r = 0.998) with a recovery of 96.8% in synthetic solution. The method performance was not dependent on solution pH over the pH range of 2-11 and ionic strength range from 1 × 10 to 0.5 mol/L sodium nitrate. The binding agent has a higher adsorption affinity for ciprofloxacin than for other drug residues, such as norfloxacin, chloramphenicol, and malachite green. The concentration of ciprofloxacin in river water determined by this method was 0.52 ± 0.3 μg/L, and the recoveries of ciprofloxacin were 96.1-102.0%.

“…The biofouling layer had an inhibitory effect on the diffusion of analyte, and thus impacted the R s of target analyte through an increased biofilm layer with deployed time [90]. This phenomenon might be explained by the facts that the filter membrane pores were physically clogged by biofilm [91,92] and interfacial physical-chemical reactions occurred between algae, metal oxides, dissolved substance, and the analyte on the membrane surface [39,93].…”

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.
