摘要：2, 3, 3, 3, 2', 3', 3', 3'-Octachlorodipropylether (S-421) is an organochlorine compound frequently used in a house as a synergist for insecticides or as a mothproofing agent for household necessities. Domestic human exposure of S-421 was evaluated by the analyses of S-421 concentration in housedust samples sucked into a vacuum cleaner. S-421 was detected in all 20 samples of the housedust at a level of 0.04 to 15.9 mg/kg. S-421 concentration in the housedust collected from a separate wooden house was generally higher than that from a towering condominium. The average S-421 level analyzed here was approximately four times higher than that reported in 1984 by Uno et al. Application of insecticides for termite control of a house, mothproofing processing of household necessities and/or spraying the aerosol pesticides for domestic use might have elevated the S-421 pollution level in a house.
