Panaji, Jul 1 (IANS): The Goa government proposes to impose a ban on Ganesh idols made of Plaster of Paris (PoP) which, after immersion, end up polluting the water source, state Environment Minister Alina Saldanha said Monday.

The state has imposed a ban on PoP idols earlier too, though such idols continue to have a market as they are relatively cheaper and have a good finish.

Saldanha, speaking to reporters on the sidelines of a government function in the capital, said: "PoP does cause a lot of pollution. The decision (to ban PoP idols) will be taken soon, much before Ganesh Chaturthi, so that people have enough time on their hands to get the right idols."

The PoP idols, often containing gypsum, sulphur, phosphorus and magnesium as well as lead paints, disintegrate slowly and, in the process, poison the waters of lakes, ponds and rivers, as well as choking the beds of water bodies.

Last year, after the state government banned the idols, it also started selling eco-friendly Ganesh idols through its handicrafts corporation.

Ganesh Chaturthi, which is scheduled for Sep 9 this year, is one of Goa's most popular religious festivals.
