Formaldehyde does not accumulate in the environment because it gets broken down by sunlight and bacteria within a few hours, nor does it accumulate in the human body because because it gets metabolized quickly.
Studies in rats, monkeys , and humans show that inhaled formaldehyde does not change the levels of formaldehyde normally present in the blood.
Yes ,it is a known carcinogen, but for this to apply you'd need to be exposed to massive amounts of it such as in an industrial application that involves producing, handling, or breathing in the vapors from it over a period of several years.
