Interim report by the Ministry of Health and Welfare’s research group on
dioxin risk assessment.
Tolerable daily intake (TDI) of 10 pg-TEQ/kg bw/day was proposed for the
immediate future. On receiving this, the Ministry of Health and Walfare
announced implementation of fact-finding surveys into dioxin emissions
from all waste incineration facilities run by local governments throughout
the country and contamination of foodstuffs in general. Incidentally, approximately
90% of dioxin emissions in Japan are said to come from waste
incineration, while 60% of human intake is said to come from consumption
of fish.
