Toxicological data:

Acute toxicity: mouse oral LD50: 1400mg/kg.

Ecological data:

The substance is harmful to the environment and can cause pollution to water and the atmosphere. Organic acids are easy to form acid rain in atmospheric chemistry and atmospheric physical changes. Therefore, when the pH value drops below 5, it will cause serious harm to animals and plants, and the reproduction and development of fish will be seriously affected. Water acidification will also lead to changes in the composition and structure of aquatic organisms. Acid-tolerant algae and fungi increase, while root plants, bacteria and vertebrates decrease, and the decomposition rate of organic matter decreases. Acidification can seriously reduce or die of fish in lakes and rivers.
