A review of food contamination with nitrated and oxygenated polycyclic aromatic hydrocarbons: toxicity, analysis, occurrence, and risk assessment.

Prolonged exposure to polycyclic aromatic hydrocarbons (PAHs) and their derivatives, particularly nitrated polycyclic aromatic hydrocarbons (NPAHs) and oxygenated polycyclic aromatic hydrocarbons (OPAHs), can result in adverse health effects and may carry higher toxicity risks compared to PAHs alone. Various extraction methods have been utilized for PAHs derivatives from food samples. The analytes are then analyzed using gas chromatography/mass spectrometry and high-performance liquid chromatography techniques. PAHs derivatives are increasingly being detected in the environment, prompting scrutiny from numerous researchers. Similarly, their presence in food is becoming a significant concern. The elevated levels of PAH derivatives found in smoked food may result in detrimental dietary exposure and pose potential health hazards. Furthermore, investigating the level of exposure to these contaminants in food is imperative, as their consumption by humans carries inherent risks. Consequently, this review concentrates on the toxicity, analysis, occurrence, and risk evaluation of NPAHs and OPAHs present in food sources. [ABSTRACT FROM AUTHOR]
