What Are PAHs in Water? Polycyclic Aromatic Hydrocarbons (PAHs) are a group of organic compounds formed during the incomplete combustion of fossil fuels, oil, wood, and other carbon-based materials. Found in everything from road runoff and industrial discharge to crude oil leaks, PAHs are persistent pollutants that can accumulate in the environment, especially in surface water, groundwater, and sediments. Many PAHs are known to be toxic, carcinogenic, and harmful to aquatic life, making accurate detection and monitoring crucial components of water quality management.
Monitoring PAHs in water is vital for industries such as petrochemical, refining, wastewater treatment, and environmental protection. Real-time oil-in-water analysis using advanced UV fluorescence sensors offers a fast, sensitive, and reliable method for detecting even trace levels of PAHs. With no need for sampling, reagents, or delays, modern PAH sensors, such as the TriOS enviroFlu, provide continuous monitoring to ensure compliance, protect ecosystems, and prevent long-term contamination risks.

Monitor polycyclic aromatic hydrocarbons (PAHs), oil-in-water, and BTX compounds with advanced UV fluorescence – fast, accurate, and reagent-free detection for process and environmental protection.
