Detection of metallic pollutants in waste water using bio sensors and its remediation
Summary
This review examines biosensor technologies for detecting metallic pollutants in wastewater, including approaches for monitoring diverse contaminants from industrial and urban sources. The study highlights how continuous real-time monitoring using biosensors can help address the growing threat of water pollution to human health and ecosystems.
Abstract Water pollution has emerged as the biggest threat to the sustenance of human civilization and the environment. With the increase in rapid industrialization and urbanization, there is a considerable increase in the influx of complex and diverse pollutants in water bodies. Hence continuous and efficient monitoring is required to detect the pollutants in the aquatic environment. Either preventing or detecting and subsequent elimination of these pollutants is of utmost importance for the health of the aquatic ecosystem. Biosensors have proved to be efficient in detecting these pollutants in a better way as compared to other conventional methods. Sensors are devices that have the ability to detect changes in the physical, chemical, or biological domains and produce a signal that can be measured. The distinguisher element in it minimizes noise caused by other components in the analyte mixture by being able to detect a specific analyte or set of analytes. This current review is focused on the role of biosensors in detecting metallic pollutants in water bodies. It also discusses the process of remediation of metallic pollutants in the aquatic environment.

Real-Time Detection of Heavy Metals and Some Other Pollutants in Wastewater Using Chemical Sensors: A Strategy to Limit the Spread of Antibiotic-Resistant Bacteria
This review examines advances in real-time chemical sensors for detecting heavy metals and other pollutants in wastewater, framed as a strategy to limit the spread of antibiotic-resistant bacteria. Researchers explain that heavy metals promote antibiotic resistance through co-selection mechanisms, making early pollutant detection critical. The study evaluates electrochemical, optical, and biosensor technologies and suggests that integrating real-time monitoring into water treatment systems could help curb the environmental spread of resistant bacteria.
Biosensors in environmental analysis of microplastics and heavy metal compounds – A review on current status and challenges
This review examines how biosensors -- devices that use biological materials to detect pollutants -- could provide faster and cheaper monitoring of microplastics and heavy metals in the environment. Current methods for detecting microplastics are expensive and time-consuming, so biosensor technology could help track contamination more widely. Better environmental monitoring is an important step toward reducing the microplastic exposure that ultimately affects human health.
