Methyl Methacrylate - PSL1

4.0 Recommendations for Research and Evaluation

1. Additional characterization is recommended of the exposure to ethyl acetate/methyl methacrylate (EA/MMA) and the volatile by-products of the EA/MMA polymerization process of the workers exposed in the early period of operation of the acrylic sheet manufacturing plant in Bristol, Pennsylvania examined in the study of Walker et al. (1991). This research is considered to be of high priority.
   
   
2. Due to the lack of information on levels in the Canadian environment and the determination of nontoxic to the Canadian environment on the assumption of very low levels, MMA should be measured in air, water, and sediment at sites adjacent to the plant using MMA. Similarly, monitoring of concentrations of MMA in environmental media (i.e., air, food, and water) to which the general population in Canada is exposed is desirable. This research is considered to be of medium priority.
   
   
3. Additional data on the neurotoxicity, immunotoxicity, and reproductive toxicity of MMA are also desirable. This research is considered to be of low priority.
