Toxicological data
1, acute toxicity: mice (peritoneal)LD50: 4,895mg/kg
Since the LD50 of table salt is 3,000 mg/kg span>, BPA has the same acute toxicity as table salt.
Ecological data
For products that are slightly harmful to water, do not let large amounts of products come into contact with groundwater, waterways or sewage systems. Do not discharge materials into the surrounding environment without government permission.
