  Furan Summary
Furan, also known as furane and furfuran, is an aromatic heterocyclic organic compound, produced when wood, especially pine-wood, is distilled.
Furan is a clear, colorless, very volatile and highly flammable liquid with a boiling point close to room temperature.
Furan is aromatic because one of the lone pairs of electrons on the oxygen atom is delocalized into the ring, creating a 4n+2 aromatic system (see Hückel's rule) similar to benzene.

 Furan  CAS No. 110-00-9  First Listed in the Eighth Report on Carcinogens  U.S. Department of Health and ...   (Site not responding. Last check: 2007-10-15)
A current hypothesis for the mechanism of furan-induced carcinogenesis is metabolic activation of furan by cytochrome P-450 to a reactive and cytotoxic intermediate that stimulates cell replication, increasing the likelihood of tumor induction (Chen et al., 1995; Kedderis et al., 1993).
Furan is used in the formation of lacquers and as a solvent for resins.
Furan was detected in 1 of 63 industrial effluents at a concentration of < 10 µg/L (Perry et al., 1979; cited by IARC V. It was also found at a concentration of 7 ± 4 ppb (dug/L) in aqueous condensate samples from low temperature gasification of rosebud coal (Pellizari et al., 1982).

Contamination was subsequently found in the soils of CFC property, in floodplain soils and river sediment of the South Branch, in sediments of nearby wetlands, and in fish taken from the river (ERG 1980, MDNR 1977).
Residences were noted along the river channel at Bowen Road and Chase Lake Road (both of which are within the original 8-mile study area, see Figure 2), and signs of human recreation within the floodplain were seen in many instances, some of which involved children.
Sampling was limited to the first river mile downstream from the former CFC facility and the "hotspots" identified in both sediment and soil in the final FS report.

Enhance the capability of the Hudson River Fisheries Unit to monitor shad, striped bass and sturgeon populations, especially the vulnerability of American shad stocks and the decline of Atlantic sturgeon, and to assess the fish populations' response to harvest control measures.
Although this portion of the river is tidal, it is largely freshwater and its fisheries are managed by the DEC Division of Fish and Wildlife.
A program of river access development is recommended to add launching ramps to reaches of the river not presently served with public facilities, to restore deteriorated facilities to a functional condition, and to expand the infrastructure of sites and facilities suitable for multiple public access uses, especially where safe access across the railroad is available.

 USGS CIRC 1161 subpage: major issues and findings in the willamette basin--Dioxins and Furans
Dioxins and furans are organic chemicals that are of environmental interest because of their acute toxicity to some animal species.
Dioxins and furans are not single chemicals, but rather families of related compounds that differ in the number and position of their chlorine atoms.
In the main stem Willamette River, dioxin and furan concentrations in bed sediment increased as the predominant adjacent land use changed from agricultural to industrial.

 Dioxins PCBs Furans and Mercury
All three compounds (dioxins, furans and PCBs) are often referred to collectively as "dioxin." They are scored for their dioxin-like potency, and described in terms of their "Toxic Equivalency Factor" (TEF) relative to dioxin.
By 1956, or earlier, Monsanto knew that their PCB products could be contaminated with dioxins (TCDD) and dibenzofurans (furans) from the time they were shipped from the factory—a piece of information the company sat on until the late 1960s, when independent researchers discovered this hazard.
Also, they were usually purified of dioxin or furan contaminants (Monsanto did this deliberately in the 1970s --- see the History section.) This means the researchers were testing a PCB mix very different from the highly toxic mixture that actually accumulates in fish.

 Columbia River: Contaminants in the Food Chain   (Site not responding. Last check: 2007-10-15)
The Columbia River is an important resource for fish and wildlife, and a number of National Wildlife Refuges (NWRs) were established along the river to protect migratory birds, species listed under the Endangered Species Act, and habitat necessary for the survival of these species.
BMFs derived based on data from Columbia River fish and bald eagle eggs were fairly consistent among river Segments 1 to 3 in the lower river, and the combined BMFs for the three segments were 113 for total PCBs, 75 for DDE, 2.8 for mercury, 16 for TCDD, and 2 for TCDF.
Currently, it is unknown if bed sediment in the Columbia River plays an important role in transfer of contaminants to biota, and additional information is needed to characterize this role and to develop better management strategies for bed sediment disturbance.

In a 1992 study, the USGS reported that dioxins and furans were present in suspended sediment collected from the Columbia River, but only a few of the 17 targeted isomers were detected.
Aside from dioxins and furans, few of the many other organic compounds associated with wood-pulp waste, urban runoff, and industrial activities were detected in the bed sediments of Lake Roosevelt and its major tributaries.
Objectives - The overall objective of the study is to characterize the extent and significance of toxic chemical contamination in the lake sediments and water.

The regulated substances are present in five processes; namely: i) the organic waste tank farm; ii) the drum storage area; iii) the pump-out/blend tanks; iv) the drum conveying area; and v) the direct feed to the kiln.
Worst-Case Release Scenario: The worst-case release scenario (WCS) for toxic substances was based on the catastrophic rupture of the single largest vessel in the organic tank farm, in which 100,000 lbs of furan in a waste mixture was considered to be spilled in a diked area.
Furan was assumed to be evaporating after the spill.

 BTF Technical Assessment Mission - Kragujevac - Zastava Car Factory
The factory is located on the banks of the Lepenica river, a small tributary of the Velika Morava, which in turn flows into the Danube some 60 km downstream of Belgrade.
The main problems reported were the leaking of several tonnes of PCBs into the Morava River, and contamination of groundwater by PCBs and heavy metals.
The visit of the environmentally relevant areas of the car factory showed, that the environmental effects due to the bombardments are restricted to two transformer sites at the ”Paint Works” and the ”Power Plant” as well as a ”Waste Storage”, where damaged transformers and barrels with contaminated sand were found.

The furan makes up about 50 percent of the mix of dioxins and furans in river sediment, and a smaller percentage, about 5 percent, of what is in Midland-area soils.
Previously, the furan had been considered half as toxic as the most potent from of dioxin, TCDD, but now is considered less than one-third as toxic, and has been assigned a "toxic equivalency factor" in relation to TCDD of 0.3.
A soil sample containing 1,000 ppt of the dioxin/furan mix, for example, depending on the portion that is the penta furan, might now be recalculated to 800.

A second pattern associated with sources up river from the pulp and paper mill was characterized by a dominant peak for 1234678-HpCDD, and smaller peaks for OCDF and 1234789-HpCDF.
This assessment indicated that 35 to 40 percent of the down river dioxin contamination could be attributed to the pulp and paper mill and the remainder was due to up river source(s).
However, because the pulp and paper mill dioxin had a relative toxicity that is more than five times greater than the up river source(s), it represents 75 to 79 percent of the dioxin TEQ risk in the lower river basin.
