[Aspects of exposure to methyl-methacrylate of varying intensity in an organism and on population levels].

Studies of mortality among 3588 workers who contacted variable doses of methylmetacrilate (MMA) revealed that higher intensity of the exposure led to increased risk of death with lung and colon cancer. Immune state studies in 157 workers proved significant immune disorders due to MMA levels several times exceeding the MAC. Experiments evaluating immune functions under exposure to MMA levels equal to or under the MAC demonstrated mostly adaptational changes.

[Specific features of adverse effects in workers exposed to different levels of methylmethacrylate].

The relation of the incidence of malignant neoplasms to the dose of methyl methacrylate (MMA) was studied in 3588 workers. There was a clear correlation between the dose of MMA and the risk for cancer of the genital system in females and of the lung in males. Examining the immunity in groups receiving different doses of MMA revealed significant immunological disorders when exposed to its high concentrations.
