摘要：We had investigated the daily intakes of chlordane from diets by the duplicate portion method from 1985 through 1987. In 1987, we had an opportunity of analyzing samples of Okinawa and we examined the regional difference of the data between Sendai and Okinawa. The level of daily intakes of trans-chlordane, cis-chlordane, trans-nonachlor, cis-nonachlor and total-chlordane in Okinawa were generally higher than those in Sendai (p<0.01). The daily intake of total-chlordane in Okinawa (1.3μg/d) reached approximately 2.4 times that in Sendai (0.55μg/d). The pattern of chlordane components contained in daily diet was much similar to that of horse mackerrel.
