甲基丙烯酸甲酯(Methgl Methacrylate,简称MMA)是聚合丙烯酸涂料的主要单体之一。由于丙烯酸涂料具有保色、保光、耐热、耐腐蚀等特点,所以常被用做家用电器、缝纫机、自行车、仪表及建筑装饰物的高档涂料。MMA是易挥发具有醚样气味的化合物,有明显地麻醉作用和刺激作用。据国内外的资料报导认为本品属中等毒性物质,除影响肝脏的解毒功能外,还可影响糖、蛋白质、色素的代谢以及心血管系统,还能使血红蛋白降低、白细胞升高。监于目前国内对MMA的毒理,对工人的症状及血压的影响报导的较少。为了进一步探讨MMA对某些生化指标及血象的影响于1988年至1989年我们对油漆分厂的制漆车间进行了MMA浓度的测定及工人血象和生化指标的检查。结果报告如下:
Methyl Methacrylate (MMA) is one of the main monomers in polymerized acrylic coatings. Because acrylic paint has the characteristics of color retention, gloss retention, heat resistance and corrosion resistance, it is often used as high-grade paint for household appliances, sewing machines, bicycles, instruments and architectural decorations. MMA is a volatile, ether-like compound with significant anesthetic and irritant effects. According to domestic and foreign information reports that this product is a moderately toxic substances, in addition to affecting the liver detoxification function, but also affect the metabolism of sugar, protein, pigment and cardiovascular system, but also to reduce hemoglobin, leukocytosis. Given the current domestic toxicity to MMA, the impact on workers’ symptoms and blood pressure is reported less. In order to further explore the impact of MMA on some biochemical indicators and blood, from 1988 to 1989, we measured the concentration of MMA and the blood and biochemical indexes of workers in paint shop. The results are reported as follows:
