Dioxin Data from Major Chlorine Producers and Users
Dioxin
Data: Releases of Dioxin to the Air, Water and Land Surface
The table displays
quantities of dioxin released to the air, water and applied to the land
surface1 . Air emissions include fugitive emissions (those
issuing from other than a point source) and stack emissions.
According to the EPA
Inventory of Sources of Dioxin in the US, in 1995 3,252 g-TEQ of dioxin
were released from quantified sources to air, water and land. (1995 is
the last year for which EPA total release data are available.) Dioxin
emissions from chlorine chemical companies participating in the survey
amounted to approximately 33 g-TEQ (2,000 grams), representing approximately
1% of the EPA's 1995 minimum total releases2. The EPA projects
that dioxin releases from all quantified sources will fall to 1,106 g-TEQ
by 2002/4.

rounded to two significant figures and totals may not equal sum of individual
categories due to rounding.
2 This percentage
is obtained for approximate comparison purposes only. The percentage compares
the reported 2000 TRI dioxin emissions from the chlorinated chemical industry
to the quantified 1995 EPA Inventory of Sources of Dioxin in the United
States (both in TEQ units). It should be noted that dioxin emission sources
reported in the 2000 TRI differ from emission sources reported in the
1995 EPA Source Inventory. In addition, while 2000 TRI reporting includes
emission to air, water and land, the 1995 EPA source inventory reports
mainly air emissions.
3This value is a minimum due to difficulties matching activity levels and emission factors for certain categories of dioxin emission sources. Consequently, approximately 10% of dioxin emissions (g-TEQ) are not accounted for in this total.
