Abstract Since polycyclic aromatic hydrocarbons (PAHs) are mutagenic, teratogenic, and carcinogenic, they are of considerable environmental concern. A biotechnological approach to remove such compounds from polluted ecosystems could be based on the use of white-rot fungi (WRF). The potential of well-adapted indigenous Ganoderma strains to degrade PAHs remains underexplored....

An improved gas chromatography-mass spectrometry (GC-MS) method was developed for the simultaneous determination of 24 polycyclic aromatic hydrocarbons (PAHs) in edible oils. A novel purification procedure based on the coupling double cartridges (molecular imprinting polymer (MIP) cartridge and PAHs special cartridge) was applied. Under the optimized conditions, the method...
