- The practical application of pear bagging is safe as far as pesticides residue is concerned.

How to decrease the pesticides residue is a new challenge during growing, storage and processing of agricultural products. Pesticides distribution or migration study would be the key point to find a pesticide removal method. 173 pesticide components in peel, pulp or paper bag were extracted by acetonitrile after fortified with chlorpyrifos-d10 as isotope internal standard. The extract was simply purified by dispersive sorbent of primary secondary amine (PSA) and then measured by online gel permeation chromatography-gas chromatography/mass spectrometry (GPC-GC/MS). The positive results were used to study the pesticides distribution properties in peel, pulp and paper bag. The pesticides distribution properties between peel and pulp were well applied for pesticides removal, risk assessment and suitable eating way for pear. Except of pesticides with strong polarity and high water solubility, most of the pesticides stayed in the skin of a pear and can be eliminated by peeling. A pear is safe for pesticides residue if eaten with peeling and might exist risk to some degree if eaten without peeling. The practical application of pear bagging is safe as far as pesticides residue is concerned.
