Opis

Komentarz do analizy

PAHs are ubiquitous in the environment, resulting from both natural and manmade sources of combustion. They can contaminate food crops through environmental exposure to particulates, automobile exhaust, etc. In the case of edible oils, additional PAHs can be introduced during actual production processes such as seed drying [1]. In this application, EZ-POP NP SPE is used to extract PAHs from soybean oil. The 16 PAHs designated in many US EPA methods (less acenaphthylene) were analyzed by HPLC-FLD after extraction from a spiked sample of oil.
