Tutkimukset

Tämän tutkimuksen tavoitteena oli selvittää voidaanko huono sisäilma tunnistaa mittaamalla sisäilmasta kerättyjen huurrevesinäytteiden toksisuus ihmissoluissa.

Tämän tutkimuksen tavoitteena oli kehittää ihmisen biologiaan pohjautuva testi, jolla voidaan tunnistaa terveydelle haitallinen sisäilma ja ”sairaat rakennukset” riippumatta sitä, mikä sisäilmaa pilaa.

Sisäilmaa on jokaisen tilankäyttäjän pakko hengittää, joten toistettaville, terveyshaitan arviointiin soveltuville näytteenkeruumenetelmille sisäilmahaittaiseksi epäillyn rakennuksen ilmasta tai rakenteista on suuri tarve.

Työn tavoite oli kehittää menetelmiä paikallistamaan haitalliset homevauriot suurista rakennuskokonaisuuksista. Uutena näytteenottotekniikkana kehitettiin toksisuusmittauksiin riittävän sisäilmanäytteen kerääminen vesihöyryä kondensoimalla

Tekstissä esitellään useita erilaisia tutkimus ja näytteenottomenetelmiä, ja niillä saatuja tuloksia

No inhalation toxicity assessment (H314) is currently required of non-volatile substances (European REACH). However, our study shows that non-volatiles can mobilise into humid air.

The hypothesis for our study was that air and airborne moisture are carriers of possible toxic compounds and these compounds can be collected as condensate using dry ice.

Penicillium expansum was identified as a major contaminant in indoor air, settled dust and materials of several buildings connected to indoor air related health complaints.

The new approach in indoor air toxicological assessment is to collect a water sample by condensing it from the air. Dew point is reached by using collectors with cold surfaces

The aim of the study was to estimate the risks of different symptoms after the exposure to indoor air dampness microbiota (DM).

Indoor air dampness microbiota (DM) is a big health hazard. Sufficient evidence exists that exposure to DM causes new asthma or exacerbation, dyspnea, infections of upper airways and allergic alveolitis.

The impurities of the air inside the buildings and the resulting adverse health effects have become an increasing problem. Typically indoor air impurities are mixtures of many chemical substances at relative low concentrations.

There is an on-going debate on how best to test toxic indoor air. Toxicological methods based on condensed water samples and cell culture technique are newly introduced research tools which were tested in this study.

Vuonna 2017 tehtiin suurin Suomessa koskaan toteutettu tutkimus koulujen sisäilman vaikutuksista opettajien terveyteen: ennätykselliset 4920 opettajaa vastasi kyselyyn. 85 % näistä vastanneista opettajista ilmoitti opetustilansa sisäilmaan liittyvän terveyshaittoja.

We aimed to establish an etiology-based connection between the symptoms experienced by the occupants of a workplace and the presence in the building of toxic dampness microbiota.

Indoor air is typically a mixture of many chemicals at low concentrations without any adverse health effects alone, but in mixtures they may cause toxicity and risks to human health. The aim of this study was by using new approach methods to assess the potential toxicity of indoor air condensates.

Potential markers were sought to diagnose mold hypersensitivity. Indoor air condensed water and human macrophage THP-1 test were applied to evaluate the buildings. Basophil activation tests (BAT) were conducted and mold-specific immunoglobulins (IgE, IgG, IgA, and IgD) were measured in study subjects’ serum and feces.
