O'LEARY, AN ASSESSMENT REPORT ON: DDT, ALDRIN, DIELDRIN, ENDRIN
, CHLORDANE, HEPTACHLOR, HEXACHLOROBENZENE, MIREX, TOXAPHENE, POLYCHLORINATED BIPHENYLS, DIOXINS AND FURANS [section] 6.
The standard solution was made up of the following pesticides: aldrin, alpha HCH [cyclohexane, 1,2,3,4,5,6-hexachloro-,(1[alpha], 2[alpha], 3[beta], 4[alpha], 5[beta], 6[beta])], beta HCH [cyclohexane,1,2,3,4,5,6-hexachloride,(1[alpha],2[beta],3[alpha], 4[beta],5[alpha],6[beta])],deltaHCH[cyclohexane,1,2,3,4,5,6-hexachloride, (1[alpha],2[alpha],3[alpha],4P,5[alpha],6P)], lindane or gamma HCH [cyclohexane,1,2,3,4,5,6-hexachloride,(1[alpha],2[alpha],3[beta],4[alpha], 5[alpha],6[beta])], dieldrin, endosulfan I, endosulfan II, endosulfan sulfate, endrin
aldehyde, heptachlor, epoxide heptachlor, 4,4'-DDD[benzene 1,1'-(2,2 dichloroethylidene) bis 4-chloro], 4,4'-DDE[benzene 1,1'-(dichloroethylidene) bis 4-chloro], and 4, 4'-DDT[benzene 1,1'(2,2,2-trichloroethylidene) bis 4-chloro].
One of the most serious chemical poisonings in DSNP occurred in 1990, when the chemical endrin
was used in the Seriang watershed, causing the death of 23 arowana parent stock fish whose value at that time was US$ 570 each.
The herbicide list included aldrin, cis-chlordane, trans-chlordane, oxychlordane, p,p'-DDD (4,4'-DDD), p,p'-DDE, (4,4'-DDE), o,p'-DDT (2,4'-DDT), p,p'-DDT (4,4'-DDT), dieldrin, endrin
, heptachlor, heptachlor epoxide isomer B, hexachlorobenzene, hexachlorocyclo-hexane (BHC) [alpha]-isomer, hexachlorocyclohexane (BHC) [beta]-isomer, hexachlorocyclohexane (BHC) [gamma]-isomer (lindane), hexachlorocyclohexane (BHC) [sigma]-isomer, methyl pentachlorophenyl sulphide (MPCPS), pentachloroani-line and pentachloronitrobenzene (quintozene).
It is interesting to note that aldrin, dieldrin, endrin
, heptachlor, HCB, mirex, and chlordane have never been used in or imported to Estonia.
These are (1) DDT or its breakdown product DDE, (2) Aldrin biphenyls, (3) Dieldrin, (4) Endrin
, (5) Chlordane broad spectrum, (6) Heptachlor, (7) Hexachlorobenzene, (8) Mirex, and (9) Toxaphene (PSR monitor, 1998 cited in Ohanjanyan, 1999).
Synthetic insecticides; aldrin, chlordane, endrin
and DDT are some of the potent insecticides, small-scale, large-scale farmers and industrialists (Jackai and Oyediran, 1991).
The "dirty dozen" are: DDT, chlordane, aldrin, dieldrin, endrin
, heptachlor, mirex, toxaphane, hexachlorobenzene, polychlorinated biphenyls (PCB), PCDD, and PCDF.
In some species, alleles resistant to specific toxic chemicals, such as ethyl alcohol, endrin
, purine, potassium sorbate, dieldrin, cyromazine, and propoxur have been selected.
poisoning in gold fish Carassius auretus.
Chlorinated compounds such as polychlorinated biphenyl congeners and chlororganic pesticides (aldrin, dieldrin, endrin
, DDT, lindane, HCB) were analysed on a 90 m capillary column (DB 5) using gas chromatography (Varian 3380) with an electron capture detector.
Proven with both ECD (Electron Capture) and MS (Mass Spectrometry) detection, each column is individually tested with key pesticides including endrin
and aldrin before shipment to ensure optimal peak shape and sensitivity.
