Whereas formaldehyde is usually secure at very low ranges, it’s extremely poisonous and dangerous at concentrations above 100 ppm. Even at a focus of fifty ppm, formaldehyde may cause probably life-threatening well being points together with a extreme pulmonary response.

Formaldehyde has a variety of business functions. For instance, it’s typically used as a chemical precursor to different extra advanced natural compounds similar to urea-formaldehyde resin. It’s additionally used to protect organic tissue throughout embalming and pattern preservation.

What’s formaldehyde?

Formaldehyde is a colourless natural compound with the chemical formulation CH₂O. It’s the only type of aldehyde and, like different aldehydes, it has a terminal carbonyl useful group.  A Graphic showing key information on formaldehyde

Formaldehyde happens naturally as an intermediate byproduct of the response between methane and oxygen. It’s produced by way of burning natural compounds, similar to within the case of fossil fuels and forest wildfires. The compound will also be detected in human blood as a byproduct of the metabolism of the amino acids serine and threonine. That stated, about 90% of the formaldehyde within the atmosphere is definitely shaped within the higher environment.

In pure type, formaldehyde exists as a pungent-smelling colourless gasoline. Nonetheless, attributable to its instability in a gaseous part, the compound is often dissolved in water for storage functions. 

Formaldehyde is usually distributed as a 37% aqueous resolution for industrial functions. At 10% focus it’s known as formalin, a product generally used as a disinfectant and preservative agent for organic specimens. Frog preserved in formaldehyde in a glass jar

What meals is formaldehyde utilized in?

As a byproduct of metabolism, formaldehyde could be discovered in lots of meals, together with:

  • Fruits, similar to apples, bananas, grapes, and plums
  • Veg, similar to onions, carrots, and spinach
  • Seafood
  • Beef
  • Poultry

Naturally-occurring formaldehyde in meals is usually secure due to its low focus (it’s generally current at ranges between 300 and 400 mg/kg). In some instances, the compound is artificially added as a preservative in seafood.

Is formaldehyde poisonous?

Identical to different chemical substances, formaldehyde has a toxicity degree. It’s extremely poisonous and turns into a risk to human life at a focus of 100 ppm. Even at a comparatively low focus of fifty ppm, it will probably trigger a number of well being points, similar to extreme pulmonary reactions, in a matter of minutes. 

Formaldehyde acts as a systemic poison that’s sometimes absorbed by the physique by way of inhalation. Anybody uncovered to it could undergo from lung irritation and pulmonary oedema, which can in some instances result in pneumonia. Extreme bronchial irritation could be deadly. Learn on to study extra concerning the results of formaldehyde on the physique.

What does formaldehyde do to the physique?

As a powerful irritant to residing organic tissues, formaldehyde may cause irritation and chemical burns. If it’s inhaled or comes into direct contact with human tissue it will probably trigger the next:

  • Extreme respiratory tract irritation
  • Pores and skin irritation
  • Dizziness
  • Suffocation
  • Extreme eye and pores and skin burns

When inhaled at low concentrations for a brief interval, formaldehyde can irritate the nostril and throat. Publicity to excessive concentrations may cause coughing, choking and even demise. A graphic showing the affects formaldehyde has on the body

Is formaldehyde flammable?

Pure formaldehyde is extremely flammable in gasoline type as it will probably simply polymerise in an exothermic response. Because of this it’s normally dissolved in water when dealt with for industrial functions. 

Whilst a liquid, the vapour from the aqueous resolution can nonetheless ignite when uncovered to excessive warmth or flame. Formaldehyde ought to subsequently be saved in a cool facility to forestall attainable explosions or hearth.

Lowering publicity to formaldehyde

As formaldehyde could be present in smoke, meals, and a few family merchandise, you may wish to contemplate the next preventative measures to scale back the chance of publicity:

  • Ban smoking indoors
  • Air new furnishings earlier than use
  • Have correct indoor air flow
  • Wash everlasting press clothes earlier than sporting them
