The Biden administration has officially determined the chemical formaldehyde poses an “unreasonable” risk to human health and should be regulated. The Environmental Protection Agency (EPA ...
In 1987, the Environmental Protection Agency classified the chemical as a probable carcinogen after unusually high or prolonged exposure. Subsequent studies have linked formaldehyde to cancers ...
Environmental factors such as temperature and relative humidity can elevate levels because formaldehyde has a high vapor pressure. Formaldehyde levels from building materials are the highest when a building first opens because materials would have less time to off-gas. Formaldehyde levels decrease over time as the sources suppress.
In males, researchers suggest that the overall reduction in cancer death rates is due in large part to a reduction in tobacco use over the last half century, estimating that the reduction in lung cancer caused by tobacco smoking accounts for about 40% of the overall reduction in cancer death rates in men and is responsible for preventing at least 146,000 lung cancer deaths in men during the ...
The third type of carcinogen is biological which highlights infections that can be caused from viruses, bacteria, or parasites. [2] There are many risk factors when it comes to the human body and carcinogens, which is why it is so important that the proper approach is used when attempting to reduce expose to cancer causing carcinogens.
Examples of activation-independent carcinogens include ultraviolet light, ionizing radiation and alkylating agents. [21] The time from exposure to a carcinogen to the development of cancer is known as the latency period. For most solid tumors in humans the latency period is between 10 and 40 years depending on cancer type. [22]
A 2015 study analyzing 10 puffs found that vaping at a high voltage (5.0 V) generates formaldehyde in e-cigarette vapor; they inferred from the finding that the user vaping at high voltage with 3 ml of e-liquid daily would inhale 14.4±3.3 mg of formaldehyde daily in formaldehyde-emitting chemicals.

In time, Zoe may suffer some of the same problems as Taoufike, a 13-year-old boy who lives in one of Parkash’s buildings. In 2005, a blood test revealed that his blood level was 32 micrograms per deciliter — an exceptionally high rate that’s over six times the amount requiring close medical monitoring under CDC guidelines.
