“…The bioassays and microbial biosensors employed for the toxicity assessment involved Chlorella sp., Chlorella vulgaris, Monoraphidium sp., Scenedesmus subspicatus and Brachionus calyciflorus sp. [378]. Due to presence of countless toxic cyanobacteria in water, Weller [379] made an attempt to study their existence using biosensors.…”

a b s t r a c tWater monitoring technologies are widely used for contaminants detection in wide variety of water ecology applications such as water treatment plant and water distribution system. A tremendous amount of research has been conducted over the past decades to develop robust and efficient techniques of contaminants detection with minimum operating cost and energy. Recent developments in spectroscopic techniques and biosensor approach have improved the detection sensitivities, quantitatively and qualitatively. The availability of in-situ measurements and multiple detection analyses has expanded the water monitoring applications in various advanced techniques including successful establishment in hand-held sensing devices which improves portability in real-time basis for the detection of contaminant, such as microorganisms, pesticides, heavy metal ions, inorganic and organic components. This paper intends to review the developments in water quality monitoring technologies for the detection of biological and chemical contaminants in accordance with instrumental limitations. Particularly, this review focuses on the most recently developed techniques for water contaminant detection applications. Several recommendations and prospective views on the developments in water quality assessments will also be included.

“…In toxicological research, bioassays and biosensors are used to estimate chemical toxicity against organisms and monitor the amounts of toxic substances in the environment (Banerjee and Bhunia, 2009;Hassan et al, 2016). The budding yeast, Saccharomyces cerevisiae, is often employed in bioassays because its genetics have been elucidated in detail and molecular engineering is easy to perform.…”

A pilot study for construction of a new cadmium-sensing yeast strain carrying a reporter plasmid with the <i>JLP1</i> promoter

-Cadmium contamination still occurs in some parts of the world, and its concentrations in the environment are monitored in most countries due to its adverse effects on human health. We herein established yeast (Saccharomyces cerevisiae) reporter assay strains carrying plasmids with the yeast JLP1, SEO1, and CUP1 promoters connected to the bacterial lacZ reporter gene. The strain carrying the high-copy number pESC-JLP1-lacZ reporter plasmid was more responsive to cadmium than strains with other reporter plasmids. This JLP1-lacZ reporter assay strain will be useful for monitoring cadmium contamination in environmental water and soil as a first screening tool preceding official instrumental analyses, because the assay is rapid, easy to handle, and has the ability to process a large number of samples at a low cost.

“…In Russia, the most common monitoring system is sampling and subsequent analysis in the laboratory, and, in rare cases, the mobile monitoring. In turn, the autonomous remote monitoring is a promising step in the development of environmental objects control methods [1][2][3][4].…”

Differential Sensor for PH Monitoring of Environmental Objects

et al. 2016

Abstract. Differential pH sensor is proposed. Reference electrode and measuring electrode are the same type. Reference electrode is immersed in standard buffer solution with known pH value. The differential pH sensor has longer service life as compared with the traditionally used sensors with silver chloride reference electrode. Ultrasonic cleaning system is proposed to clean the primary measuring transducer from pollution that form as result of silting during long-term operation with the sensor.
