Cyanogen chloride: Risk assessment, environmental, and health hazard

Cyanogen chloride (CK) is a colorless gas with a bitter and pungent smell like pepper. It is extremely volatile and toxic in nature that obstructs the body's capability to oxygen consumption. As CK is used commercially in chemical synthesis and as a disinfectant byproduct (DBP) in chloraminated and chlorinated drinking water as well as in wastewater It is essential to have adequate knowledge about this gas with respect to its properties, effects, sources, treatment methods, and the recent research to prevent toxicological effects on environment and human. This chapter briefly discusses the risk factors, assessment, and management in risk analysis of CK.
