“…Another significant source of dye contamination in water bodies is Toluidine Blue, a phenothiazine dye which has been reported to have mutagenic effects and is hazardous to both DNA and RNA. These findings highlight the importance of responsible dye usage, proper disposal, and effective wastewater treatment processes to minimize the environmental and health risks associated with dye pollutants [25,30–32] . Some list of textile dyes toxicity towards aquatic microalgae and macrophytes are shown in Table 1.…”

The global manufacturing sector heavily relies on the textile industry, yet the widespread utilization of synthetic dyes within this sector has raised serious environmental apprehensions, notably regarding wastewater contamination. The release of untreated wastewater containing residual dyes poses a significant risk to both aquatic ecosystems and human well‐being. In reaction to this issue, considerable efforts have been made to develop efficient and sustainable methods for the removal of textile dyes from wastewater. This comprehensive review paper furnishes in‐depth literature information covering various aspects of dyes, including their classification, toxicity effects, and evaluation of recent advancements in dye removal technology, emphasizing their advantages, limitations, and future potential. Various strategies are covered, including physical, chemical, and biological methods. Physical techniques like adsorption, filtration, and membrane technologies are contrasted with chemical approaches such as coagulation, precipitation, and advanced oxidation processes. Biological methods include the utilization of micro‐organisms, fungi, and enzymes to break down or metabolize dye compounds. Key considerations in the critical analysis include the efficiency, cost‐effectiveness, and scalability of each method. This review focuses on enzyme breakdown (biological) and adsorption (physical) color removal procedures, which are currently considered the most effective. It also proposes the utilization of a composite adsorbent, anticipating enhanced efficiency and faster removal of dyes through this technique.

“…To overcome these pollution problems, ethidium bromide and other toxic compounds could be partially or completely degraded to nontoxic forms before disposal. Consequently, some research laboratories worldwide are testing the biodegradation of ethidium bromide using plants and various kinds of microorganisms, including bacteria and microalgae [50][51][52][53], to develop, in the next future, modern, cost-effective, and eco-friendly bioremediation approaches.…”

Environmental pollution is a severe and common problem in all the countries worldwide. Various physicochemical technologies and organisms (e.g., plants, microorganisms, etc.) are used to address these environmental issues, but low-cost, practical, efficient, and effective approaches have not been available yet. Microalgae offer an attractive, novel, and little-explored bioremediation alternative because these photosynthetic organisms can eliminate pathogenic microorganisms and remove heavy metals and toxic organic compounds through processes still under study. Our research team has conducted some experiments to determine the bioremediation potential of native microalgae on some pollutant sources (i.e., leachate and wastewater) and its ability to remove hazardous chemical compounds. Therefore, in this chapter, we provide the results of our research and updated information about this exciting topic. Experiments were conducted under controlled culture conditions using several native microalgae species, variable time periods, different pollutant sources, and hazardous chemicals such as ethidium bromide. The results indicated that native microalgae can remove pollutants (i.e., phosphorus, ammonia, etc.) of wastewater, leachate, and some hazardous chemical compounds such as ethidium bromide. In conclusion, native microalgae have an excellent potential for removing several pollutants and, consequently, could be used to develop bioremediation technologies based on native microalgae from the Peruvian Amazon.

“…Concerning electrochemical detection of EtBr, reports in the literature exhibit limits of detection typically in the micro molar concentrations of range. This limitation of detection may not be fit-for-purpose for on-site detection as smaller concentrations of this substance may cause damage over time; thereby highlighting the need for a more sensitive detection method [37], [38]. To date, electrochemical methods have been more successfully applied to remediation of the molecule [39], [40], [41] rather than detection.…”

Ethidium bromide (EtBr) is one of the most used non-protein molecules in molecular biology, specifically for fluorescence-based detection of nucleic acids during gel electrophoresis. ETBr2 fluoresces when exposed to ultraviolet light, intensifying after binding to DNA. Although non-radioactive, the ability of EtBr to bind preferentially to the double strand structure and to enter the nucleus membrane of cells makes it a toxic substance, which can cause tumorigenesis due to the genetic damage induced by its interaction. Its reputation as a potential mutagen has created a need to minimize its use and eliminate the risks associated with exposure, as well as the potential environmental hazards associated with disposal. In the last 10 years, EtBr has also been shown to be electrochemically active. In this work, we show the modification of an ultra-micro electrode sensor and subsequent detection of EtBr from Phosphate buffer on a nanomolar level (LoD of 12 nM). The sensor can detect concentrations with a higher sensitivity and reliability than the classic UV lamp in a practical manner. This novel sensor may offer a potential solution to test for and reduce potentials risks associated with both job related risk and unwanted environmental release of EtBr.
