Hydrogen selenide: Risk assessment, environmental, and health hazard

Hydrogen selenide (H2Se) is a colorless, nonmetallic, and hazardous air pollutant. It is a hydrogen chalcogenide that exists in gaseous form. The contamination of this gas may thereupon cause respirational disorder, liver disorder, other severe health effects, and antagonistic ecological effects. Being flammable in nature, H2Se presents a severe fire hazard and mandates the evaluation of any probable risks. Hence, the chapter discusses the potential risk assessment and management techniques involved in H2Se toxicity. This chapter also critically assesses the hydrogen selenide toxicity and its hazardousness on humans and the environment.
