ECOLOGICAL INFORMATION

Since it is so intensely corrosive, nitric acid released into channels or the environment can seriously harm aquatic life.
It can generate nitrous oxide when it reacts with organic matter in the environment, which can add both atmospheric pollution & the greenhouse effect.
Nitric acid can also cause soil acidity, which can harm plant growth and microbiological activity in the soil.
Nitric acid’s fumes or vapors can irritate the respiratory system & harm lung tissue in both humans & animals.
In order to reduce dangers, proper protective gear and spill response methods should be used when there has been a leak/spill or release of nitric acid.
In order to avoid contaminating the environment and to ensure safe usage and disposal, nitric acid should really be stored & handled in compliance with all applicable municipal, state, & federal standards.
In the event of an unintentional discharge, the spill must be contained & cleaned up with the proper methods and tools to limit additional harm to the environment or to human health.

DISPOSAL CONSIDERATIONS

Dispose of in accordance with local, state, & federal rules or laws.
