PAHs are exposed to humans in natural sources such as volcanic eruptions, crude oils, or forest
fires, and artificial combustion sources such as industrial processes, fossil fuels, vehicles, etc.
Analysis of PAHs in surface water was conducted by ChroZen HPLC according to EPA 810.
Because it required the detection of several ppb levels of PAHs, an FLD (Fluorescence Detector)
was utilized for superior sensitivity.
