The adverse effects of industrial wastewater are well-known for deteriorating the quality of life through producing and releasing hazardous pollutants like polycyclic aromatic hydrocarbons (PAHs) into the water bodies. This review describes different sensing approaches for detecting and monitoring PAHs (such as phenanthrene, anthracene, fluoranthene, acenaphthene, chrysene, pyrene, and perylene) in industrial wastewater. Sensor methods are the most feasible and widely accepted approach for detecting and analysing PAHs in industrial wastewater. The sensor's performance is compared to alternative methods such as high-performance liquid chromatography (HPLC) and gas chromatography & mass spectrometry (GC-MS). The relative performance of different sensor-based detection methodologies is evaluated in essential quality assurance. Also, it highlights current limitations and future developments in the methodological approaches for their detection.
