Air concentrations of heptachlor, chlordene, chlordanes, and Nonachlors were measured at a dormitory town and other three houses in Japan. The samples of air under the floor, in the room, and in the open were concentrated on the soli absorbent Tenax-GC at normal temperature, and directly injected at 280℃into the capillary column gas chromatograph. Some of the results were over above the NAS interim guidelines of 2.0 μg/m3. The maximum concentration was 5.8μg/m3 in the room, and 16 μg/m3 under the floor. It has been prohibited to make, to sale, and to use the chlordanes since September 1986 in Japan. But chlordanes residue in the living area shall persist for a long time. At present the organophosphorus and pyrethroid in secticides are used as substitutes for chlordanes. Because these acute toxicities are more remarkable than chlordanes, the inhabitant seem to suffer from new damages of health.
