This will lead to an increase in the level of reactive metabolites and result in an increased reaction of these metabolites with intracellular macromolecules.

Cut a total of eighteen (18) 4" soil lines in the engine room and plug or cap the remaining pipe leading to the six scuppers (seven cuts starboard and eleven port).

In addition to reduced hepatic glutathione leading to an increase in the binding of reactive metabolites of VC with macromolecules, such an effect may also be associated with other dose dependent alterations in the fate of VC in the body.

This leads to two types of disease.

This will lead to an increase in the level of reactive metabolites and result in an increased reaction of these metabolites with Intra cellular macromolecules.

This concept leads to a much more meaningful interpretation of the dose-response data and permits more meaningful extrapo lations of that data.

This will lead to an increase in the level of reactive metabolites and resultt in an increased reaction of these metabolites with intra cellular macromolecules.

In addition to occupational exposure, low-level environmental contamination can occur from combustion of styrene-based products, as the thermal decomposition of polystyrene leads to evolution of the monomer, in contrast to other polymer materials.

The U S. is the world's leading consumer, taking 185 of the total, and is also C anada s main market, importing 735.150 tons in 1974. over 405 of the Canadian mine output.

Several metabolites have been found and several poten tial routes of metabolism have been illustrated, but which of these, if any, leads to carcinoma and other changes is not known.
