3,035 commercial agricultural products collected from the northern area of Seoul in
2014 were analyzed for 285 pesticides by GC-ECD/NPD and HPLC-DAD/FLD using a
multi-residue method. Pesticide residues were detected in 13.7%(415) of the samples and
exceeded maximum allowable limits in 0.5%(15) of the samples. Agricultural products
that were most frequently contaminated were leek(54.2%), green and red peppers
(48.0%), chamnamul(45.5%), sedum(37.5%), and ginseng(36.0%). Among the 15 most
contaminated samples, the majority was leek(in 7 cases); with procymidone, chlorfenapyr,
and cypermethrin the pesticides most frequently found. Pesticide residue limits were
exceeded for procymidone in 8 cases, for chlorpyrifos and flutolanil in 2 cases each,
and for bifenthrin, iprodione, and thifluzamide in 1 case each. The ratio of estimated
daily intake(EDI) to acceptable daily intake(ADI) ratio, used here as a risk assessment
tool, was calculated to be in the range of 0.618 to 16.922%. This suggests that
consuming commercial agricultural products with pesticide residues at these levels should
not pose a major risk to human health.
