“…In short, the surfaces from where the emissions were spread (floor, ceiling, walls) were covered with a flexible emissions barrier to prevent them from reaching the indoor air. In the specific barrier used, the cTrap, an adsorption layer functions together with a hydrophilic polymer sheet making the adsorption virtually irreversible [1,2]. The flexible cTrap cloth was attached at the surfaces using an adhesive tape and/or a staple gun.…”

“…VOC from paints, glue, insulation materials, chipboards, microorganisms, impregnation and plasticizer chemicals, or toxins from microorganisms such as mould. In the present study we applied a new type of emissions barrier [1,2] developed at Lund University Sweden to stop such emissions thereby improving the indoor air in buildings with IAQ complaints.…”

A new type of emissions barrier was used in premises with indoor air complaints due to moisture driven emissions from the buildings in question. The emissions comprised chlorophenols/chloroanisoles and polycyclic aromatic hydrocarbons (PAH) from treated wood, and volatile organic compounds (VOC), mainly 2-ethylhexanol, from PVC flooring and the glue used to paste the flooring onto a concrete slab. Attaching the barrier at the surfaces from where the emissions were spread (floor, walls, ceiling) resulted in a fresh and odour-free indoor air. We conclude that using an emissions barrier in buildings made unhealthy by moisture is an efficient way of restoring a pleasant and healthy indoor air.Peer-review under the responsibility of the organizing committee of the ICMB21.

“…It may be applied directly at the source of the emissions, such as moisture-affected floors and walls, which results in an immediate stop or reduction in the emitting pollutants. It reduces about 98% of air pollutants, such as volatile organic compounds (VOCs) or mould particleassociated mycotoxins [111].…”

Introduction and objective. The course of COVID-19 caused by the SARS-CoV-2 may be aggravated by bioaerosols containing other viruses, bacteria, and fungi, occurring mainly in the occupational environment. Hence, the diagnostics and treatment of COVID-19 should address such a possibility in the anamnesis, treatment and final recommendations for avoiding of adverse exposure. Abbreviated description of the state of knowledge. As SARS-CoV-2 attacks primarily the respiratory system and the severe manifestation of COVID-19 is interstitial pneumonia, diagnostics should include the following clinical and laboratory examinations: chest X-ray; high resolution computed tomography (HRCT); pulmonary function tests; arterial-blood gas test; genetic tests for the presence of SARS-CoV-2, in the future with the use of highly specific and sensitive nano-based biosensors; tests for the presence of specific immunity against the antigens of microorganisms causing other infectious or allergic pulmonary diseases (in the case of anamnestic indications). Because an universally accepted treatment for COVID-19 does not exist, the hitherto prescribed antiviral and immune-modulating drugs should be used be with caution. In many cases, a better alternative could be a safe supportive therapy, such as supplementation of the diet with probiotics, prebiotics, vitamins and microelements. Conclusions. The most important preventive measures against COVID-19 should include: vaccination; the use of filter or surgical masks; disinfection and sterilization; maintaining of well-functioning ventilation and air conditioning systems; reduction of the community air pollution which has been identified as an important factor increasing the COVID-19 severity. In the choice of preventive measures, the above should be considered for their potential efficacy against other bioaerosols as potential disease-aggravating agents.

“…For VOC removal, activated carbon will be required in the filtration component, but the efficacy of the device will drop as surfaces of the activated carbon filters rapidly reach saturation with adsorbed VOCs. (Markowicz & Larsson, 2012).…”

“…In one instance, for example, Markowicz and Larsson (2012) conducted the experiment in a 2.6-littre plastic box, with 1-cm diameter hole to allow for sampling of air through a tube before and after the experiment for a GC-MS analysis. In another case, the air-purifier's ability to remove organic matter and floating germ in indoor air (Kim et al, 2006) was measured using an 800 l-capacity chamber.…”
