1 in 5 rooms is "highly contaminated" with hidden mould

02.05.2008
Surely your bathroom is fungus-free once you’ve wiped the mould off the tiles?

Not according to a study by French scientists in the Royal Society of Chemistry’s Journal of Environmental Monitoring. They report that almost one in five rooms studied with no visible mould was in fact “highly contaminated” by fungus which could aggravate conditions such as asthma.

The study also found that bedrooms and living rooms were no less contaminated than bathrooms and kitchens – “hidden” fungus was not only airborne but found in carpets and soft furnishings, and behind wallpaper, and was often colourless and odourless.

When assessing a building’s level of contamination, many authorities rely on trained investigators to see or smell the fungus – Sandrine Roussel, lead author of the article, and collaborators say this is not enough. By completing questionnaires and sampling the air in hundreds of homes in France, they found that what you see is not always what you get.

“Nowadays, no one would agree to live in housing which presents any risks towards lead or carbon monoxide. Tomorrow, moulds and other chemical substances will probably follow,” says Roussel.

Mould in the home is not just unsightly and indicative of poor hygiene standards; it is known to aggravate a range of medical conditions, such as asthma, rhinitis and hypersensitivity pneumonitis. This study set out to establish if more could be done to identify fungus as exacerbating these complaints.

Surprisingly, the study found that factors commonly held to increase mould contamination had relatively little effect. The age of the building, presence of pets and even outdoor and indoor temperature had little bearing on fungus concentration.

As for airborne fungi, it made little or no difference if the room was regularly used to dry clothes, or contained indoor plants – factors that public health inspectors had previously highlighted as key issues.

The researchers found that significant factors in levels of contamination were structure, such as lack of ventilation or a ground floor apartment, or accidental damage, such as water damage.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
