Polycyclic aromatic hydrocarbons (PAHs) are a product of incomplete combustions. Foods prepared via combustion and high temperature are linked with incomplete combustion making them vulnerable to having PAHs in their constituent. Two species of fish: stock fish and cat fish were bought from Ogbomoso and smoked using firewood and charcoal at various time intervals. The processed samples were...

Abstract Industrialization often causes polycyclic aromatic hydrocarbon (PAH) and heavy metal contamination of soil and water. In this study, we isolated a bacterium from bottom mud water around a park of Kawasaki Port, Japan, that degrades the 5‐ring PAH dibenz[a,h]anthracene (DBA). The strain, Comamonas sp. 3ah48, degraded 29% of DBA (30 μg ml−1) in 7 days, and the degradation level increased...
