||Specific emission rates were calculated on the basis of material balances for each of the 6 operations in sole manufacture; the results are presented in a table. The largest quantity of gaseous pollutants are emitted during vulcanisation (85-95% of the total emissions for the process). Of the 4 types of sole produced, coloured porous rubber gave the largest amounts of gas, black solid rubber the smallest. The average composition of the gaseous emissions was: 1.2% aldehydes, 28% aromatic hydrocarbons (of which 2% styrene), 1.5% amines, 7% naphthenes, 8% normal and iso-paraffins (3-7 carbons), 7.5% normal and iso-olefins, 16% for 8-14-carbon paraffins, 12% for 8-14-carbon olefins, and 20.3% unidentified. An equation was derived for predicting the quantity of emissions from the amounts of natural rubber, blowing agent, regenerated rubber and mineral filler used in the process.
