| 毒性: |
The acute toxicity of methyl methacrylate is low. Irritation of the skin, eye, and nasal cavity has been observed in rodents and rabbits exposed to relatively high concentrations of methyl methacrylate. The chemical is a mild skin sensitizer in animals. The effect observed most frequently at lowest concentration after repeated inhalation exposure to methyl methacrylate is irritation of the nasal cavity. Effects on the kidney and liver at higher concentrations have also been reported. The lowest reported effect level for inhalation was 410 mg/m3 in rats exposed to methyl methacrylate for 2 years (based upon inflammatory degeneration of the nasal epithelium); the no-observed-effect level (NOEL) in this investigation was approximately 100 mg/m3 . The toxicity of methyl methacrylate to aquatic organisms is low. Although no chronic studies on aquatic organisms were identified, acute tests have been conducted on fish, Daphnia magna, and algae. The most sensitive effect was the onset of inhibition of cell multiplication by the green alga Scenedesmus quadricauda at 37 mg/litre following 8 days of exposure. The lowest reported 24-hour EC50 for immobilization in Daphnia is 720 mg/litre. The 96-hour LC50 in juvenile bluegill sunfish (Lepomis macrochirus) under flowthrough conditions was 191 mg/litre, whereas LC50 values for durations of 1–24 hours ranged from 420 to 356 mg/litre, respectively. The 96-hour LC50 for rainbow trout (Oncorhynchus mykiss) under flow-through conditions was >79 mg/litre, the highest concentration tested. Sublethal/behavioural responses were noted among the fish at 40 mg/litre. |
