ABSTRACT
Foundry in Belgaum is the only relatively modern. A foundry is a casting manufacturing system. Casting is the process of forming objects by pouring liquid metal into prepared mould and allowing the melt to solidify. The foundry operations generate different kinds of air pollution, depending upon the kinds of furnace in use and the kinds of energy inputs that they use.

The present study indicates the air pollution concentration …show more content…
Over a period of four decades, the foundry industries in Belgaum has not grown to the expected level due to the lack of infrastructure facilities, advanced testing facilities, and pollution-related International Conference on Technology and Business Management problems. Belgaum exports variety of castings to various countries both directly and through export agents. Foundry forms one of the major industrial sectors of Belgaum. It is also one of the major economies of Belgaum. There are 142 foundries at present in Belgaum, out of which 76% is small scale, 21% are medium scale & 2% are large scale foundries. The Belgaum foundries produce different types of casting ranging from 500gm to 1.8Tons. The major raw material required for foundries are sand (washed & unwashed), resin & alloys. The major loss that is incurred by the foundries is the wastage of sand as about 10-10,000Tons of sand is wasted while …show more content…

MATERIALS AND METHODOLOGY
METHODS FOR THE POLLUTANTS
According to the Central pollution control board (CPCB) the methods prescribed for the pollutant gases and the particulate pollutants are very sensitive ones yet percentage of errors are very less. The methods prescribed for the gases SO2, NO2, NH3 and the particulate pollutants PM10 and PM2.5 are respectively:

1) Improved West and Gaeke method for SO2.
2) Modified Jacob and Hochheiser method for NO2.
3) Indophenol method for NH3.
4) Gravimetric method for PM10.
5) Gravimetric method for PM2.5.

The purpose is to lay down a uniform and reliable method for sampling and analysis of SO2, NO2, and NH3 in the ambient air and also to lay down a uniform and reliable method for measurement of PM10 and PM2:5 in the ambient air of three zones for foundry clusters of Belgaum city.
