Painting of Karmalghat crash barriers ‘causing air pollution’
CANACONA: With the world talking about using eco-friendly paints, the contractor who is assigned the job to paint the crash barriers at Karmalghat has been using solvent based enamel, even though the world has moved to water based paints, in recent years.
Public utilities like buildings, bridges, roads amongst other things are major consumers of paints, which is used either as a decorative layer or for protection of the structure underneath or to make the painted structure more visible or all of the above.
The PWD highways, for the above reasons, have entrusted the painting of the crash barriers at Karmalghat to a private contractor.
The under coat and the enamel that the contractor is using is solvent based; the strong fumes emanating out of this paint has left the surrounding polluted, complain the commuters.
The solvent existing in the paint and the one added later to thin it escapes in the open environment leading to irreversible damage to the environment, allege environment conscious locals.
The smell of solvents over a large painted area of the crash barrier across the NH66 at Karmalghat has affected the people living around and passing along this road. And many who have inhaled this strong odour have reported nasal congestions and difficulties in breathing.
Leading paints manufacturers in India have lately come up with compositions and formulations which use water as the thinning solvent which are safe to both humans and nature.
Paint technogists and experts say that the water thinable enamels are cheaper, more durable, have excellent UV properties, emanate lower odour and has reduced volatile organic compounds. The developed world has quickly adapted to the advances in the paint industry and it is high time the authorities make the use of more eco friendly paints mandatory all over India.
“The volatile gases escape from the paint while drying and get trapped in the atmosphere there by polluting it,” said a student of paint technology while emphasising that it is time to switch over to less polluting paints.
