Application of spectroscopy technology in detecting toxic effects of environmental pollutants

Due to the swift progress of industrialisation and urbanisation, the issue of environmental pollution has escalated significantly, presenting a significant peril to human well-being and the ecology. The identification of harmful impacts caused by environmental contaminants is highly important for evaluating environmental hazards, developing measures to reduce pollution, and safeguarding public health. Spectroscopic techniques offer a potent means of environmental monitoring because to their exceptional sensitivity, quick response, and non-destructive detection capabilities. This article provides an overview of the basic principles and categorisations of spectroscopic methods, such as ultraviolet-visible spectroscopy, fluorescence spectroscopy, infrared spectroscopy, and Raman spectroscopy. It delves into the specific uses of these techniques in identifying particular contaminants in water, soil, and the atmosphere. The article centres around the capacity of spectroscopic techniques to detect and measure environmental contaminants, particularly biotoxic contaminants such as heavy metals, organic pollutants, and bacteria. A comparative analysis reveals the superiority of spectroscopic approaches over traditional chemical analytical methods in terms of sensitivity, detection limits, ease of operation, and cost-effectiveness.
