※Sick Building Syndrome
Sick building syndrome is an allergic
reaction to indoor chemicals. The presence
of chemicals such as formaldehyde indoors
can cause symptoms such as coughing,
itchy skin, and fever.
Do you know the formaldehyde?
Formaldehyde substance is included in pressed-wood products, such as
particleboard, plywood, fiberboard, glues and adhesives components of wood.
There is an essential component to ensure water resistance and toughness. It is
used a lot in many products, such as building materials and wooden furniture.
However, formaldehyde is categorised as a carcinogen by IARC. Particularly
recognized as a substance that causes cancer and leukemia. It also increases the
risks to our health, such as sick building syndrome*1 and chemical sensitivity.

Current situation of formaldehyde emission
WHO established the indoor air quality guideline
that the formaldehyde exposure limit is up to
0.1mg (100㎍)/㎥=（0.08ppm）for indoors.

History of human damage caused by formaldehyde
The potential health impact of low-level ambient formaldehyde gas has been
historically overlooked.
For example, there is related ambient formaldehyde gas in 5,325,585 deaths in
275 Chinese local governments nationwide between 2013 and 2018.

Formaldehyde is widespread in India
Reference: Why does India's air look different from space? https://www.bbc.com/news/science-environment-44550091
Data obtained from observation satellites shows that large amounts of
formaldehyde gas exist in the air in India and other Asian countries.
It can be considered that this is also affecting the indoor environment in
India.

concentration in India is expected
to be higher than that in China.
