Anthropogenic CO₂ emissions has enforced policymakers for proper CO₂ capture technologies planning. One of the well-established technologies for CO₂ capture is the amine-based post-combustion CO₂ capture. Amines have been found to undergo nitrosation, producing nitrosamines and nitramines, which are potent carcinogenic, toxic and mutagenic. Investigations on the formation of nitrosamines, nitramines and their destruction are at the state of the art for amine-based post-combustion CO₂ capture technology. However, most literature is only based on water treatment practices. Nitrosamines are more potent carcinogenic than nitramines. However, nitramines are more stable than nitrosamines. Formation of nitrosamines through post-combustion CO₂ capture is mainly a function of NOx content in flue gas. However, other contaminants like SOx and chlorine also affect nitrosamines formation. Atmospheric formation of nitrosamines and nitramines is due to loss of amine to the environment through aerosols, amines mist and amine vapors. Every technology has some limitation in eliminating nitrosamines and nitramines. However, photolysis and UV treatment through advanced oxidation processes are more effective. This study provides an alarmist situation of nitrosamines and nitrsamines associated with amine-based post-combustion CO₂ capture technology based on the both, literature available for water treatment as well CO₂ capture.
