Formaldehyde is a common industrial chemical and VOC (Volatile Organic Compound) found in many types of wooden furniture, disinfectant, glue and insulation material.
In our home, products emiting formaldehyde include plywood shelf, wall paper, fiberboard table, cigarette smoke, window sealant, particleboard chair, floorboards, carpeting and pesticides.
These products emit formaldehyde over time as a clour-less gas.
I was informed that some fishermen also apply formaldehyde to preserve the fish and ikan bilis as well as keep away flies. The next time you purchase fish and ikan bilis from the markets, just watch out if there are any flies around.
In short, formaldehyde is always in the air.
A high level concentration of formalhehyde in the air can cause eyes to water, coughing and wheezing as well as irritation of the nose and throat.
All of us have to take care to reduce the contact with formaldehyde.
That is the reason my friend advises me not to shift into new house within six month of its completion.
