“…More recently, these two miniaturized BioETs were combined and applied towards the prediction of wastewater quality at different purification stages in a wastewater treatment plant (Czolkos et al 2016). The two systems were incorporated in a FIA system and used to predict several organic pollutant indexes commonly used to assess wastewater treatment processes, including Microtox®, algae test, chemical oxygen demand (COD), biochemical oxygen demand (BOD) and total organic carbon (TOC).…”

“…Reprinted from [58], with permission from Elsevier Bioelectronic Tongues Employing Electrochemical Biosensors toxicity, BOD, COD and TOC, a key factor important for the development of chemometrically stabilized commercial wastewater sensors was initiated, but with non-conclusive results. An equivalent system has been further applied in a very recent work to urban and industrial wastewaters from a paper mill [59], where the eight-sensor screen-printed electrode was operated in a flow-injection system and where different pollution index related to organic load (COD, BOD, TOC and toxicity) was successfully estimated through PLS regression. Simultaneous determination of several global environmental parameters characterizing wastewaters is possible with this kind of biosensor array, in particular because it was possible to establish the correspondence between the sensor responses and the biological effect onto the ecosystem into which the wastewater is to be released.…”

This chapter presents recent advances concerning work with electronic tongues that employ electrochemical biosensors, that is, bioelectronic tongues. (Bio)electronic tongues represent a new methodological use of (bio)sensors; they start by the use of biosensor arrays and assume the coupling of the obtained complex response with advanced chemometric data treatment; the goal is improving performance of existing sensors. Most of the bioelectronic tongues reported employ enzyme biosensors, essentially based on potentiometric or voltammetric/ amperometric transduction. This report is organized considering the different forms to incorporate biosensors, i.e. considering the number of biosensors in the array, the number of different enzymes used, if the determination is aimed to substrates or inhibitors, etc. Significant applications in real problem-solving, mainly in the food and clinical or environmental fields, are commented.

“…Another work [ 16 ], reports on using Pt electrodes instead of screen-printed ones and self-made carbon paste was applied as a sensing layer. The paper implies that such a procedure may improve sensitivity of the substrate for some of the immobilized enzymes.…”

Water quality is one of the most critical indicators of environmental pollution and it affects all of us. Water contamination can be accidental or intentional and the consequences are drastic unless the appropriate measures are adopted on the spot. This review provides a critical assessment of the applicability of various technologies for real-time water quality monitoring, focusing on those that have been reportedly tested in real-life scenarios. Specifically, the performance of sensors based on molecularly imprinted polymers is evaluated in detail, also giving insights into their principle of operation, stability in real on-site applications and mass production options. Such characteristics as sensing range and limit of detection are given for the most promising systems, that were verified outside of laboratory conditions. Then, novel trends of using microwave spectroscopy and chemical materials integration for achieving a higher sensitivity to and selectivity of pollutants in water are described.
