Their high fat-solubility and the fact that some arc metabolised and oxcroted only very slowly leads to their concentration and accumulation in the fatty tissues of living organisms* This persistence and accumulation* coupled with uncortaintien about long-term effects of low concentrations, in the basis of the need for special consideration in disposal of wastes.

Our programs toward this end include investigations of the fundamental mechanisms leading to resin adherence to polymerizer surfaces and a wide variety of methods aimed at eliminating adherence, chemically and/or
