Further information and evaluation of all known data led the IARC to reclassify formaldehyde as a known human carcinogen [75] associated with nasal sinus cancer and nasopharyngeal cancer. [76] Studies in 2009 and 2010 have also shown a positive correlation between exposure to formaldehyde and the development of leukemia , particularly myeloid ...
In addition to being an allergen, it is a formaldehyde releaser, since it generates formaldehyde slowly as it degrades. Although the formaldehyde acts as a bactericidal preservative, it is a known carcinogen. In 2005–06, it was the 14th-most-prevalent allergen in patch tests (3.7%). [4]
DMDM hydantoin is an antimicrobial formaldehyde releaser preservative with the trade name Glydant. DMDM hydantoin is an organic compound belonging to a class of compounds known as hydantoins.

To the average consumer, formaldehyde may be best known as an embalming agent. But this naturally occurring chemical is a major industrial staple, used in many consumer goods, including cleaning ...
The production of DMEU is through the condensation of formaldehyde with ethylene urea: [9] 2CH 2 O + (C 2 H 4 N 2 H 2)CO → (C 2 H 2 N 2 (CH 2 OH) 2)CO. The reaction proceeds around 200 °C (392 °F) but this temperature can be brought down to around 70 °C (158 °F) in the presence of an acid catalyst. [10]
Nov. 13—Chemical compounds linked to cancer were detected in five wells in the La Cienega and La Cieneguilla communities south of Santa Fe, with the likely source being a nearby National Guard ...
A Times analysis found that the problem of failed water systems is particularly acute in Kern County, where about 131,500 residents are served by 65 failed systems — the highest number of ...
Methylmercury, a worldwide contaminant of seafood and freshwater fish, is known to produce adverse nervous system effects, especially during brain development. Eating fish is the main source of mercury exposure in humans and some fish may contain enough mercury to harm the developing nervous system of an embryo or fetus, sometimes leading to ...
