“…[12][13][14] Therefore, its precise determination in the environment and living organisms is highly important in terms of public health. Until today, a number of different analytical methods for the determination of the lead(II) ions have been used in the field, such as atomic absorption spectrometry (AAS), [15,16] inductively coupled plasma-mass spectroscopy (ICP-MS), [17,18] liquid chromatography, [19] stripping voltammetry [20,21] and UV-visible spectrophotometry. [22] Since these methods require a qualified personnel and specific and sensitive analytical instruments, and they are also expensive, laborious and time consuming, they are not quite suitable for the on-site analysis.…”

In this study, a novel PVC‐based membrane containing (E)‐2‐(1‐(4‐(3‐(4‐chlorophenyl)ureido)phenyl)ethylidene)hydrazine carbothioamide (5) as an electroactive component (ionophore) along with potassium tetrakis (p‐chlorophenyl) borate (KTpClPB) and bis(2‐ethylhexyl)adipate (DEHA) in the ratio 4.0 : 32.0 : 1.0 : 63.0 (ionophore:PVC:KTpClPB:DEHA) (w/w) was used to develop a lead(II)‐selective potentiometric sensor. The sensor exhibited a Nernstian response over a wide concentration range from 1.0×10−5 to 1.0×10−1 mol L−1 with a slope of 28.0±2.0 mV/decade, and a detection limit of 1.65×10−6 mol L−1. It displayed very good selectivity towards Pb(II) ions over other cationic species. The lead(II)‐selective sensor showed a fast response time of 5 s, good repeatability, and it worked in the broad pH range of 5.0–11.0. The sensor could be used as an indicator electrode in the quantification of Pb(II) by potentiometric titration against ethylenediaminetetraacetic acid (EDTA). In addition, this sensor was applied for the direct determination of Pb(II) in different water samples including spring water, purification water, commercial water, waste water and in a waste battery sample.

“…Physicochemical methods, such as high-performance liquid chromatography [ 1 ] and atomic absorption spectroscopy [ 2 ], make it possible to accurately define the types of chemical toxicants and their concentrations, but do not determine the degree of the toxic effect of substances on the natural ecosystem and do not reveal synergistic and antagonistic effects. The toxic impact of sample components can be established only using biological techniques, which imply the use of various trophic levels of living organisms: fish [ 3 , 4 ], plants [ 5 , 6 ], invertebrates [ 7 , 8 ], and microorganisms [ 9 , 10 , 11 ].…”

Microbial mediator biosensors for surface water toxicity determination make it possible to carry out an early assessment of the environmental object’s quality without time-consuming standard procedures based on standard test-organisms, and provide broad opportunities for receptor element modifying depending on the required operational parameters analyzer. Four microorganisms with broad substrate specificity and nine electron acceptors were used to form a receptor system for toxicity assessment. Ferrocene was the most effective mediator according to its high rate constant of interaction with the microorganisms (0.33 ± 0.01 dm3/(g × s) for yeast Saccharomyces cerevisiae). Biosensors were tested on samples containing four heavy metal ions (Cu2+, Zn2+, Pb2+, Cd2+), two phenols (phenol and p-nitrophenol), and three natural water samples. The «ferrocene- Escherichia coli» and «ferrocene-Paracoccus yeei, E. coli association» systems showed good operational stability with a relative standard deviation of 6.9 and 7.3% (14 measurements) and a reproducibility of 7 and 5.2% using copper (II) ions as a reference toxicant. Biosensor analysis with these systems was shown to highly correlate with the results of the standard method using Chlorella algae as a test object. Developed biosensors allow for a valuation of the polluted natural water’s impact on the ecosystem via an assessment of the influence on bacteria and yeast in the receptor system. The systems could be used in toxicological monitoring of natural waters.
