Cycasin is a carcinogenic and neurotoxic glucoside found in cycads such as Cycas revoluta and Zamia pumila. Symptoms of poisoning include vomiting, diarrhea, weakness, seizures, and hepatotoxicity. In metabolic conditions, cycasin is hydrolyzed into glucose and methylazoxymethanol (MAM), the latter of which dissociates into formaldehyde and ...
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 ...
Formaldehyde also occurs naturally in many fruits, such as bananas, apples, and carrots, and does not bioaccumulate in either plants or animals. [4] Formaldehyde works to fixate the tissue of the deceased. This is the characteristic that also makes concentrated formaldehyde hazardous when not handled using appropriate personal protective equipment.
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 ...
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]
Researchers using high-tech air monitoring equipment rolled through an industrialized stretch of southeast Louisiana in mobile labs and found levels of a carcinogen in concentrations as much as 20 ...
Concerns over a chemical found in furniture and flooring have put the public on alert over formaldehyde. Long-term exposure to the chemical has often been linked to cancer in humans.
Carcinogenic to humans and animals such as mice, rats, horses, and cattle when ingested. The carcinogenic compound is ptaquiloside or PTQ, which can leach from the plant into the water supply, which may explain an increase in the incidence of gastric and oesophageal cancers in humans in bracken-rich areas.
