Half of the study population had detectable [gamma]-HCH in serum, followed by p,p'-DDT (42.8%), [beta]-HCH (41.3%), p,p'-DDE (39.5%), heptachlor (32.9%), a-HCH (30.9%), and endrin (30.6%).
The tested OCPs included pp-DDT and its metabolites pp-DDD and pp-DDE; hexachlorohexanes (HCHs) including [alpha] HCH and [gamma] HCH; heptachlor and heptachlor epoxide; aldrin and endrin; chlordane, methoxychlor, and HCB.
The mixed standard of OCPs (methoxychlor, [alpha]-endosulfan, [beta]-endosulfan, [alpha]-, [beta]-, [gamma]-, and [delta]-hexachlorocyclohexane (HCH), heptachlor, dieldrin, aldrin, endrin, endosulfan sulphate, p,p'-DDE, p,p'-DDD, p,p'-DDT, and gamma-chlordane) was obtained from Supelco (PA, USA).
The OCP congeners were grouped as follows: DDT (4,4'-DDT, 2,4'-DDT, 4,4'-DDE, 2,4'-DDE, 4,4'-DDD, 2,4'-DDD, methoxychlor); Chlordane (oxy-chlordane, [gamma]-(trans)-chlordane, [alpha]-(cis)-chlordane, trans-nonachlor, cis-nonachlor); endosulfan ([alpha]-endosulfan, [beta]-endosulfan, endosulfan sulfate, heptachlor, heptachlor epoxide); endrin (Aldrin, dieldrin, endrin, endrin aldehyde, endrin ketone); HCH ([alpha]-hexachlorocyclohexane, [beta]-hexachlorocyclohexane, [gamma]-hexachlorocyclohexane, [delta]-hexachlorocyclohexane).
The results show concentrations of HCB/ hexachlorobenzene (4.0-29 pg.[m.sup.-3]), [alpha]-endosulfan (1.8-20 pg.[m.sup.-3]), [beta]-endosulfan (0.5-2,5 pg.[m.sup.-3]), [alpha]-HCH/ hexachlorocyclohexane (<LD a 3.2 pg.[m.sup.-3]), endosulfan sulfate (0.5-2.5 pg.[m.sup.-3]), endrin (<LD a 1.9 pg.[m.sup.-3]) e p,p"-DDT/dichloro-diphenyl-trichloroethane (<LD a 0.06 pg.[m.sup.-3]) emitted by point sources of long distances in both environmental matrices [36].
The twenty-five OCPs (AccuStandard, Inc., NY, US) used in this study were as follows: aldrin; cis-chlordane; trans-chlordane; oxychlordane; o,p -DDD; p,p'-DDD; o,p'-DDE; p,p'-DDE; o,p'-DDT; p,p'-DDT; dieldrin; endosulfan I; endosulfan II (ES II); endrin; [alpha]-hexachlorocyclohexane ([alpha]-HCH); [beta]-HCH; [gamma]-HCH; 5-HCH; heptachlor; cis-heptachlor epoxide (cHCP); trans-heptachlor epoxide (tHCP); hexachlorobenzene (HCB); isodrin; methoxychlor (MOC); and mirex.
By your side [10] Modifications were carried out in the analysis of pesticides, optimizing the qualitative and quantitative analysis of different compounds for the quantitation was used the gas chromatography, between the metabolites studied was endosulfan sulphate, Endrin, Chlorpyriphos Ethyl and methyl, Diazinon, pirimiphos methyl and dichlorvos, among others.
Los compuestos representativos son: DDT, aldrin, dieldrin y endrin, asi como endosulfan y lindano.
All together 23 pesticides (among them endosulfan, chlorfenvinphos, alachlor, atrazine, isoproturon, chlorpyriphos, trifluralin, simazine, glyphosate, AMPA and MCPP and some chlorinated pesticides such as aldrin, dieldrin, endrin, isodrin, hexachlorocyclo-hexanes, etc.) were investigated.
