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.
Residents reported breathing difficulties, persistent flu-like symptoms, eye irritation, and nosebleeds. The cause was suspected to be high formaldehyde levels in the trailers. [12] Formaldehyde was known to increase risk of cancer, asthma and other respiratory problems, [13] and children and the elderly were at greater risk. [12]
One study found that VOC concentrations were higher in retail storage spaces compared to the sales areas, particularly formaldehyde. [90] In retail spaces, formaldehyde concentrations ranged from 8.0 to 19.4 µg m −3 compared to 14.2 to 45.0 µg m −3 in storage spaces. [90] Occupational exposure to VOCs also depends on the task.
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 ...
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 ...
A 2015 study hypothesized from the data that at high voltage (5.0 V), a user, "vaping at a rate of 3 mL/day, would inhale 14.4 ± 3.3 mg of formaldehyde per day in formaldehyde-releasing agents." [ 17 ] The 2015 study used a puffing machine showed that a third-generation e-cigarette turned on to the maximum setting would create levels of ...
Resins containing formaldehyde have been used in fabric for years to keep clothes wrinkle-free and make them last longer. A 2010 study by congressional researchers found that formaldehyde levels ...
KGAN-TV out of Cedar Rapids tested 20 trailers in the Cedar Rapids area under contract with a nationally certified chemical testing company, [112] with testing kits finding unsafe levels of formaldehyde in six of them, according to Environmental Protection Agency and American Lung Association limits, which are more stringent than FEMA's or Iowa ...
