Mustard gas

Mustard gas though technically not a gas and often called sulfur mustard by scholarly sources is the prototypical substance of the sulfur-based family of cytotoxic and vesicant chemical warfare agents which can form large blisters on exposed skin and in the lungs They have a long history of use as a blister-agent in warfare and along with organoarsenic compounds such as Lewisite are the

Hydrogen Sulfide

Hydrogen Sulfide or sour gas (H2S) is a flammable colorless gas that is toxic at extremely low concentrations It is heavier than air and may accumulate in low-lying areas It smells like rotten eggs at low concentrations and causes you to quickly lose your sense of smell Many areas where the gas is found have been identified but pockets of the gas can occur anywhere

Hydrogen Sulfide Corrosion: Its Consequences Detection

----- Chapter 3 What Causes Hydrogen Sulfide Corrosion? • Mechanism of Sulfide Corrosion Hydrogen sulfide corrosion can occur by two mechanisms: 1) acid attack resulting from the biological conversion of hydrogen sulfide gas to sulfuric acid in the presence of moisture and 2) direct chemical reaction with metals such as copper iron and silver with hydrogen sulfide gas

Four Reasons Why Hydrogen Peroxide Water Treatment Is Best

Hydrogen peroxide converts hydrogen sulfide gas and iron present to a solid particle which is then removed by a back-washing self-cleaning carbon filtration system For many applications no retention tank is needed and any residual hydrogen peroxide will be effectively removed by the carbon filter
