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.
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 Living Building Challenge (LBC) Red List contains chemicals commonly used in building materials that have been designated as harmful to "health and the environment". ". The International Living Future Institute (ILFI) created the list in 2006, and is the only organization that uses the term 'Red L
Xylene and formaldehyde worsen allergic inflammation in animal models. [67] Toluene also increases the dysregulation of filaggrin: a key protein in dermal regulation. [68] this was confirmed by immunofluorescence to confirm protein loss and western blotting to confirm mRNA loss. These experiments were done on human skin samples.
Despite genuine concerns, formaldehyde is a naturally occurring substance, of which human beings produce approximately 1.5 oz a day as a normal part of a healthy metabolism. Formaldehyde also occurs naturally in many fruits, such as bananas, apples, and carrots, and does not bioaccumulate in either plants or animals. [4]
Formaldehyde does not accumulate in the environment, because it is broken down within a few hours by sunlight or by bacteria present in soil or water. Humans metabolize formaldehyde quickly, converting it to formic acid, so it does not accumulate. [27] [28] It nonetheless presents significant health concerns, as a contaminant.
“We’re already exposed through our electronics, automobiles, furniture … this is part of the big picture of exposure,” she adds. Liu says her advice is the same as it's been: “If you can ...
Toxic: a chemical that has a median lethal concentration (LC 50) in air of more than 200 parts per million (ppm) but not more than 2,000 parts per million by volume of gas or vapor, or more than 2 milligrams per liter but not more than 20 milligrams per liter of mist, fume or dust, when administered by continuous inhalation for 1 hour (or less if death occurs within 1 hour) to albino rats ...
