Indoor air quality concerns

According to the Humidity and Air Quality Observatory in Spain, since the pandemic, indoor air quality has created a concern that has increased by 69%.

This arises because of concerns about the increase in structural humidity in buildings, the increase in new building work (which has increased by 60%) and radon gas.  

The Observatory pointed out that Catalonia has the most structural problems recorded. And the areas most exposed to carcinogenic radon gas are Gaul, Extremadura, Asturias, Castile and Leon.

The sick building syndrome

Have you ever heard of sick building syndrome? It is an indoor space where 20% or more of the occupants have a health problem arising from particles or toxic elements in the air.

These buildings can have different characteristics such as no ventilation system, poor air distribution, airtightness, poor quality materials, poor air filtration or poor/non-maintenance, or being located in an area with high air pollution.

In addition to this syndrome, there are several pollutants or harmful particles in enclosed spaces that we have mentioned in other blog articles—for example, viruses, bacteria, allergens, dust, pet dander, and mould. And the emission of chemicals from cleaning products, dilapidated appliances and other items at home increases the presence of toxic particles we breathe in daily.
