Indoor Air Quality Analysis for Public Building IPU

Asthma or allergy like uninfectious Many chronic diseases are directly indoor air quality It is linked to (iaq) degradation . Therefore, for public access buildings (PUBs) to protect public health and safety air quality analysis is becoming increasingly necessary. Various gases can be found indoors in working or living areas. To accurately detect and monitor exposure levels to different gases in PABs, it is important to understand their presence. These gases are emitted mainly due to:

• The presence of a chemical pollutant such as benzene or formaldehyde in the exhaust when using building materials such as paint or insulation foams.
• Age of the building. Hygiene institutes and indoor air quality studies in workplaces shed light on the negative health effects of substances used in the past.
• New high-quality construction standards for insulation and sealing that aim to recycle rather than renew indoor air.

Carbon dioxide (CO2) occurs naturally in low concentrations in the air; It is colorless, odorless and heavier than air. This gas directly affects human health such as headache and fatigue. When people gather in a poorly ventilated area, such as an office, classroom, or small room in a public building, the amount of carbon dioxide in the air will increase.

Benzene, It is the most dangerous indoor air pollutant. Current standards tend to limit its spread in public buildings. The International Agency for Research on Cancer (IARC) classifies benzene as a category 1 (R25) carcinogen. If swallowed or inhaled, this organic compound is also harmful to the respiratory tract – especially the lungs (R65) – and the eyes (R36).
