The scientists analyzed furan
from the irradiated samples, using solid phase microextraction and gas chromatography-mass selective detection techniques.
Particularly convincing results have been shown by the use of furan
resin in combination with sand and a mineral additive.
Synthesis of Naphthoxazines Containing Furan
ester derivative (1) and malformins A (2) and C (3) used for the preparation of standard solutions were isolated from the marine-derived fungus Aspergillus niger (BRF 074) as previously described .
On the other hand, the fraction of furans
Of particular interest is the Y-C (Y = O in furan
, Y = NH in pyrrole, and Y = S in thiophen) bond distance.
Coffee made espresso makers contain more toxic, carcinogenic furans
than regular drip machine brews or even instant coffee, according to research conducted at the University of Barcelona.
Dioxins and furans
were evaluated in attic dust of residential structures and in blood of residents of four communities where wood treatment facilities are located: Alexandria, Louisiana; Pineville, Louisiana; Grenada, Mississippi; and Florala, Alabama.
Not only that, but the bacterium produces furan
dicarboxylic acid (FCDA) from HMF, which can act as precursor in the production of PET.
USDA-ARS scientists set out to determine whether furan
can be induced by irradiation in common freshly cut fruits and vegetables which vary widely in their sugar and ascorbic acid content.
Composite samples of LCT from the 2002 and 2003 year classes that were submitted for chemical analysis showed concentrations of PCBs and furans
that were noticeably higher than in the other Pacific Region samples.
