Molds are harmful to health and aggravate allergies

In a previous article we discussed the very varied forms of indoor air pollution. Among these forms, microorganisms, and in particular molds, are one of the main air pollutants.

In France, the national "Housing" campaign carried out between October DESK3 and December DESK5 by the Observatoire de la Qualité de l'Air Intérieur (OQAI) in nearly 600 dwellings revealed that about 40% of the residential stock was contaminated by mold, which represents more than 9 million dwellings nationwide, of which more than 610,000 had visible contamination of more than 1m². mold, which represents more than 9 million dwellings nationwide, among which more than 610,000 had visible contamination of more than 1m².

Spores spread through the air

To get into your home, spores use humans, including deposition on clothing, and all other available "vehicles" such as drafts and animals. Once in your home, molds use these spores again to proliferate throughout your home. The spores grow quickly, especially in moist environments, and are very resilient. These spores are a real air pollutant, which is why it is generally considered These spores are a real air pollutant, which is why it is generally considered that molds are one of the main sources of indoor air pollution.

The effects of mold on health and allergies:

  • With regard to the allergic risk, the health effects associated with fungal exposure by inhalation relate to asthma and allergic rhinitis. The symptoms observed when an allergic reaction is triggered result The symptoms observed when an allergic reaction is triggered are the result of a specific immune response with the production of antibodies. The threshold of allergic reactivity varies from one individual to another and the severity of the allergic reaction is not proportional to the dose of exposure.
  • The toxic or inflammatory risk is related to exposure to mold components (fungal spores, β-glucans and other components of the mycelium cell wall) and/or their metabolic products (mycotoxins, mVOCs).The effects The effects observed are of variable severity, either acute or chronic. It is not always easy to distinguish allergic effects from inflammatory effects called "non-allergic" corresponding to identical symptoms but involving a specific immune response in the case of an allergic reaction, and non-specific in the case of an inflammatory reaction.
  • The infectious risk associated with inhalation exposure to molds in indoor environments, i.e. the multiplication of the fungus in the host organism associated with the appearance of symptoms, mainly concerns the development opportunistic fungal infections. The development of these pathologies depends mainly on the immune status of the host: state of immunodepression related to a pathology or to the taking of drug treatments.

Mold can therefore have adverse effects on your health. To diagnose you, your doctor may ask you to identify the variety(s) of mold present in your home. There are very many varieties of molds. Here are the most common in mainland France:

  • Alternaria is very common (especially in summer); it gives colonies ranging from grey to black, rather fluffy. It parasitizes decaying plants.
  • Aspergillus is found everywhere. Depending on the species (there are nearly 300), the colonies range from white to grey through shades of yellow, green and blue. It is found in soil, compost, organic debris.
  • Cladosporium is the most abundant of the molds. Its colonies, more or less brownish, range from dark olive green to black and readily grow in the soil, on food, window frames, textiles, painted surfaces, even on dying plants.

Things not to do when you have mold in your home

When cleaning up your mold, be careful not to add pollutants to pollutants!

  • Avoid bleach, as it is toxic to you and bad for your furniture.
  • Do not use fungicides unless advised by a specialist.
  • Avoid encouraging the spread of spores in the air. For example, do not break the mold support, especially if the contamination is severe.

It is important to pay attention to mold and not leave it lying around. Take care of it!
