| Abstract | olycyclic aromatic hydrocarbons (PAH) are a group of chemicals which compose of two or more fused aromatic rings (Figure 1). PAH are ubiquitous in environment. PAH are also commonly used as intermediate in the production of plastics and plasticiser, dyes and pesticides. The increasing demand for manufactured goods from fossil fuels that contained compounds may also contribute PAH to the environment. Furthermore, human activities such as open burning, manufacturing of charcoal, incineration, fumes from vehicles, cigarettes smoking and cooking techniques also contributed to PAH contamination in the environment. PAH are toxic compounds and reduced exposure to these chemicals is proposed due to their toxicity effects and risk to human health. Major sources of exposure to PAH contamination are through contaminated foods and polluted air. Foods can be contaminated with PAH that are present in the air (deposition), soil (transfer) or water (via deposition and transfer), or during improper preparation, processing and cooking of the foods. Processing of food such as drying and smoking at high temperature, grilling, roasting and frying also contributed towards PAH contamination in foods (Guillen, 1997; Philips, 1999). PAH are chemically stable compounds formed in different food matrices. Some of PAH that deposited on the surface of crops might undergo degradation while others might react with components of food matrices during prolong storage (Howard and |
