More than 85% of the population in Cambodia is strongly dependent on agriculture, of which freshwater aquaculture is one of the most important sources of food production. The smoked fish represents an important source of nutrients for Cambodian population; however, it can also lead to excessive intake of polycyclic aromatic hydrocarbons (PAHs). A field survey was conducted among selected smoked fish producers near to Tonle Sap river in Kampong Chhnang province, Cambodia. The study revealed that maximal limits for benzo[a]pyrene and the sum of four PAHs given by EC 1881/2006 were exceeded 2-50 times. Such burden can lead to increased risk of development of carcinogenic diseases.
