Toxicity Tus mob toxicity ntawm methyl methacrylate yog tsawg. Kev khaus ntawm daim tawv nqaij, qhov muag, thiab qhov ntswg kab noj hniav tau raug pom nyob rau hauv nas thiab luav raug rau cov concentrations ntawm methyl methacrylate. Cov tshuaj yog ib tug me me daim tawv nqaij sensitizer nyob rau hauv cov tsiaj. Cov txiaj ntsig tau pom ntau zaus ntawm qhov qis tshaj plaws tom qab rov ua qhov nqus tau rau methyl methacrylate yog khaus ntawm qhov ntswg kab noj hniav. Cov teebmeem ntawm lub raum thiab daim siab ntawm cov concentration ntau dua kuj tau tshaj tawm.
