Abstract
A majority of contaminations generated in the casting production is related to molding and core sands: preparation of sands, producing of molds and cores, mold pouring with molten metals, mold cooling and knocking out, and reclamation of spent molding sands. Dangerous chemical substances depend on molding sands composition, liquid metal temperature, and the atmosphere in molds. Several evolving substances have carcinogenic or mutagenic influence (PAHs, BTEX), being hazardous for employees. At the economical utilization of spent molding sands, the attention should be drawn to the possibility of elution of dangerous substances from these sands.
