From: Effects of the absorbent types on changes in benzo[a]pyrene and volatile compounds in sesame oil
Effects of different types of activated carbons on the reduction of benzo[a]pyrene in sesame oil. The symbols of the samples are as follows: Control, sesame oil sample with no treatment; PP, sesame oil sample filtrated with powdered activated carbon made from peat; GC, sesame oil sample filtrated with granular activated carbon made from coconut shell; PC, sesame oil sample filtrated with powdered activated carbon made from coconut shell; GW, sesame oil sample filtrated with granular activated carbon made from wood; PW, sesame oil sample filtrated with powdered activated carbon made from wood. Data are expressed as mean ± SEM (n = 3). The presence of different letters (a–d) indicates a statistical difference at P < 0.05 between bars
