Coscolla C, Yusa V, Beser MI, Pastor A: Multi-residue analysis of 30 currently used pesticides in fine airborne particulate matter (PM 2.5) by microwave-assisted extraction and liquid chromatography-tandem mass spectrometry. J Chromatogr A. 2009 Dec 18;1216(51):8817-27. Epub 2009 Oct 28.
Recoveries ranged from 72 to 109% and the limit of quantification (LoQ) was 32.5 pg m (-3) for chlorpyrifos, 13.5 pg m (-3) for fenhexamid, imazalil and prochloraz, and 6.5 pg m (-3) for the rest of pesticides, when air volumes of 760 m (3) were collected.
Nineteen out of 30 pesticides investigated were found in at least one sample: omethoate, carbendazim, acetamiprid, thiabendazole, malathion, flusilazole, metalaxyl, azoxystrobin, iprovalicarb, myclobutanil, tebuconazole, triflumizole, cyprodinil, tebufenpyrad, buprofezin, pyriproxyfen, hexythiazox, flufenoxuron and fenazaquin. |
