Scientists led by Javier Santos, a professor at the Department of Analytical Chemistry at the University of Barcelona said in the journal <em>Food Chemistry</em> that higher concentrations of furans
are found in espresso (43a[euro]146 nanograms per mililitre) than in coffee made in drip coffee makers, with normal coffee getting higher readings (20a[euro]78 ng/ml) than decaffeinated coffee (14a[euro]65 ng/ml).
Our study was limited, for it focused on only two select congeners out of the 75 dioxin and 135 furans
that exist, and only looked at the sum of 17 dioxin/furan
congeners to evaluate total TEQs.
The formation of furan
was correlated with the pH, sugar content, titratable acidity and ascorbic acid content of the produce.
After processing, samples for dioxin and furan
analysis were submitted to the analytical laboratory on July 19, 2004.
The glass fiber reinforced composites were prepared by a mixture of equimolar MAF and furan
resin (40 wt% of total glass cloth) dioxane was stirred well for 2 to 5 min.
2010, on incineration imposes equip the chimneys of incineration plants with a semi-continuous measurement of dioxins - furans
Figure 3 shows a comparison of the percentage tensile loss in the interval test versus the B scale mold hardness gauge measurement for the furan
The measured levels of dioxins and furans
were as much as 16 times lower than the Ontario emission limits.
OBJECTIVES: We tested the hypothesis that altered expression of genes related to cell cycle control, apoptosis, and DNA damage may contribute to the carcinogenicity of furan
CEMEX subsequently conducted testing, supervised and approved by CDPHE, which clearly showed that, at the temperatures the plant operates under, there were no exceedances of dioxin or furan
USDA-ARS scientists wanted to see if furan
could be caused by irradiation in common freshly cut fruits and vegetables which vary widely in their sugar and ascorbic acid content.
Lufkin's lines are each capable of producing 40 tons/hour of phenolic urethane or furan
nobake bound sand, and the reclamation equipment is scheduled for completion in mid-2008 by Simpson Technologies Corp.
