What science says
compound effect
“Seven dried ginseng root products were found to contain combinations of the following pesticides: dacthal, diazinon, DDT, hexachlorobenzene, iprodione, lindane, procymidone, and quintozene (1-460 ng/g).”
“Pesticides were extracted with ethyl acetate and purified with gel permeation chromatography (GPC) and primary/secondary amine modified silica (PSA)/graphitized carbon black (GCB) combination SPE column.”
“The detection limits for most of the pesticides were 0.025-0.05 microg/g using GC-FPD but were analyte-dependent for GC-MS/SIM, ranging from 0.005 to 0.50 microg/g. Quantitation was determined from 0.050 to 5.0 microg/g with r 2 > 0.99 for a majority of the pesticides using both detectors. Recovery studies were performed by fortifying the dried ground ginseng root samples to concentrations of 0.025, 0.1, and 1.0 microg/g, resulting in recoveries of >90% for most pesticides by GC-FPD.”
