Biological-chemical treatment of polycyclic aromatic hydrocarbon contaminated soil / Salina Alias
Industrialization has caused a great deal of environmental pollutions such as soil contamination via deposition and spillage of contaminants. One of the major contaminants is high molecular weight (HMW) polycyclic aromatic hydrocarbon (PAH), specifically the benzo(a) pyrene. Benzo(a)pyrene is known...
