Furan, which is possibly carcinogenic, usually appears in products that have been thermally processed.
Even though furan is reliable for the high production requirements of cores and molds as a binder system in 3D printing, some small weaknesses are present.
The suspected cancer-causing substance in the rum ether, an additive used to give the spirit its rummy flavour, is furan. The association claims that the ether contains a very small share of furan and that consumers would have to drink 4-5 litres of the spirit daily in order to develop health problems.
The insertion of furan groups into polymers has been explored as a strategy that combines the search for high-performance materials with the search for the development of biobased materials, since these groups have shown to be able to confer good thermal and mechanical properties to the materials and can be obtained from renewable raw materials such as hemicellulose.
As part of an investigative effort to find promising anticancer agents from marine-derived fungi [6-8], the chemical investigation of a strain of Aspergillus niger (BRF074), recovered from sediments of the Northeast Brazilian coast, yielded the new furan ester derivative (1) and the cyclopeptides malformins A (2) and C (3) [9] (Figure 1).

New reports examine furan and perchlorate and addenda are provided for earlier reports on acrylamide, arsenic, deoxynivalenol, and mercury.
In this work, we report our investigation on the alane-trihalide (Al[X.sub.3], X = F, Cl, and Br) donor-acceptor complexes [X.sub.3]Al-Y[C.sub.4][H.sub.4] (Y = O in furan, Y = NH in pyrrole, and Y = S in thiophen) compared to the alane [H.sub.3]Al-Y[C.sub.4][H.sub.4] ones.
Terasawa et al produced a lignocellulose molded product with adequate moisture resistance by mixing the bioresin with furan resin.
According to Santos, "The reason for these higher levels is due to the fact that hermetically-sealed capsules prevent furan, which is highly volatile, from being released, and the coffee makers used to brew this kind coffee use hot water at higher pressures, which leads to the compound being extracted into the drink."&nbsp; The longer that coffee is exposed to the air in cups or jugs, meanwhile, the more the furan evaporates.
