Objective: Polycyclic aromatic hydrocarbons (PAHs) are not only natural but also anthropogenic contaminants that exist in many places the environment. Human beings often accidentally ingest PAHs via smoking. Furthermore, smoking may increase risk of bowel disorder, including diarrhea and other gastrointestinal problems. Therefore, PAH exposure is hypothesized to be related risk. This study disc...

To degrade chrysene, a polycyclic aromatic hydrocarbon (PAH) found in crude oil contaminated soil by bioremediation the Polyporus sp. S133, a fungus collected from soil was used. Maximal degradation (86%) was obtained when Polyporus sp. S133 was incubated in 0.5% tween 80 for 30 days, as compared to 30% degradation rate without tween 80. Chrysene was indeed degraded by Polyporus sp. S133 throug...

Pyrene is a very resistant polycyclic aromatic hydrocarbon (PAH) with four benzene rings that survives in the environment. This study was aimed at investigating tolerance of earthworms soil contaminated pyrene. The studies were performed by employing gathered from shady regions adjacent to sewage ponds as pyrene degraders eradicate soil. Numerous factors affecting degradation efficiency explore...
