A Mini-Review for an Adsorption of Polycyclic Aromatic Hydrocarbons (PAHs) by Physical Gel
On 4 December in 2002, the mainstream source of exposure to Polycyclic Aromatic Hydrocarbons (PAHs) was defined by the Scientific Committee as food and inhaled air. Several Polycyclic Aromatic Hydrocarbons (PAHs) such as benzo[a]pyrene, chrysene, and dibenzo(a,h)anthracene in food caused the risk of human health. These are produced by the cooking processes, including combustion processes and pyrolysis sources. Certain food preparation methods like grilling, roasting, and smoking are accumulated PAHs in the sink pipes. As PAHs are toxic and carcinogenic, it raises health and environmental problems. What is the method for preventing PAHs exist in wastewater? This review article introduces a functional material, gelatin physical gels, to trap and remove the PAHs. The physical gel changes from colorless to pale yellow during the adsorption of PAHs in household wastewater. The concentration of PAHs is determined by GC-MS analysis, which decreases the potential risk of human exposure in an environment with PAHs.
