Abstract |
Sampling of ductile iron casting in green sand molds with phenolic isocyanate cores and in phenol-formaldehyde bound shell molds did not provide definitive proof that environmentally hazardous organic emission occur. Both molding systems produced the same type of major emissions, alkyl halides, carboxylic acid derivatives, amines, substituted benzenes, nitrogen heterocyclics, and fused aromatics in quantities that slightly exceed the lowest Minimum Acute Toxicity Effluent (MATE) values for the categories, but probably not for individual compounds. GC-MS analysis revealed the major fused aromatics to be naphthalene compounds. Quantitative analysis of specific PNA's showed no significant level of concern. Inorganic dust emissions are hazardous if uncontrolled because of silicon, chromium, and nickel. The dust is sufficiently high in 12 metals to render it a hazardous waste if collected as a sludge and landfilled, but leachate testing may change that categorization. Relatively high levels of Sr, Ba, Ce, Pr, and Nd in the dust indicate that inoculation smoke should be examined. |
