Toxicological data
1, acute toxicity: Rat (oral) LD50: 4,556 mg/kg
Rat (inhalation)LCLo： 3,200 mg/m3/4H
Since the LD50 of table salt is 3,000 mg/kg, BPA has the same degree of acute toxicity as table salt.
Ecological data
If it is slightly harmful to water, do not Allow undiluted or large amounts of product to come into contact with groundwater, waterways or sewage systems. Do not release material into the environment without government permission. A large amount of discharge into rivers and sewers can cause an increase in pH. Excessive pH will be harmful to organic matter in the water. Concentration dilution during use can greatly reduce the PH, thereby reducing the harm to water caused by product discharge.
