Organochlorine pesticide residues were analyzed by capillary gas chrom
atography-electron capture detection (GC-ECD) on 101 Galician (NW Spai
n) honey samples. Of the 101 honey samples, 13 were free from detectab
le residues. The pesticides found were HCH (isomers other than lindane
) present in 47 samples (trace to 161 mug/kg), lindane in 57 samples (
trace to 59 mug/kg), heptachlor in 29 samples (trace to 57 mug/kg) ald
rin in 36 samples (1 to 150 mug/kg), dieldrin in 9 samples (trace to 1
3 mug/kg), endrin in 1 sample (7 mug/kg), op'DDT in 7 samples (1 to 12
mug/kg), pp'DDT in 18 samples (1 to 61 mug/kg) and methoxychlor in 11
samples (19 to 593 mug/kg).
