It is likely that damage or cell proliferation of the nasal epithelium is a prerequisite for cancer from gas phase formaldehyde. Therefore, the risk of cancer can be assumed negligible as long as the exposure is below 2018-06-01 We found that cancer cells produced formaldehyde through demethylation process by serine hydroxymethyltransferase (SHMT1 and SHMT2) and lysine-specific histone demethylase 1 (LSD1). When the cancer cells metastasized into bone marrow, the elevated endogenous formaldehyde induced bone cancer pain through activation on the transient receptor potential vanilloid subfamily member 1 … Formaldehyde (/ f ə r ˈ m æ l d ə h aɪ d / fer-mal-duh-hahyd, also / f ɔːr ˈ m æ l d ə h aɪ d / for-) (systematic name methanal) is a naturally occurring organic compound with the formula CH 2 O (H−CHO). The pure compound is a pungent-smelling colourless gas that polymerises spontaneously into paraformaldehyde (refer to section Forms below), hence it is stored as an aqueous Rat studies indicate that cytotoxicity-induced cell proliferation (NOAEL at 1 ppm) is a key mechanism in development of nasal cancer. However, the linear unit risk approach that is based on conservative ("worst-case") considerations is also used for risk characterization of formaldehyde exposures. A planned mechanism-based risk assessment for formaldehyde is then described.

Background: Formaldehyde (H 2 C=O) is a flammable, colourless reactive compound and readily polymerized gas at normal pressure and room temperature with a relative molecular mass of 30.03 and a pungent odour. A planned mechanism-based risk assessment for formaldehyde is then described. This risk assessment uses data on target tissue dosimetry, size of the target cell population in the rat nasal epithelium, number and size of putative preneoplastic lesions, and tumor incidence.
