Marsh gas, also known as swamp gas or bog gas, is a mixture primarily of methane and smaller amounts of hydrogen sulfide, carbon dioxide, and trace phosphine that is produced naturally within some geographical marshes, swamps, and bogs.
Nitrous oxide is a greenhouse gas with a global warming potential 300 times that of carbon dioxide and is the dominant ozone-depleting substance emitted in the 21st century. [10] Excess nutrients mainly from anthropogenic sources have been shown to significantly increase the N 2 O fluxes from wetland soils through denitrification and ...
Sewer gas is a complex, generally obnoxious smelling mixture of toxic and nontoxic gases produced and collected in sewage systems by the decomposition of organic household or industrial wastes, typical components of sewage. [1] Sewer gases may include hydrogen sulfide, ammonia, methane, esters, carbon monoxide, sulfur dioxide and nitrogen oxides.
This is a list of gases at standard conditions, which means substances that boil or sublime at or below 25 °C (77 °F) and 1 atm pressure and are reasonably stable. List [ edit ]
Hydrogen sulfide (H2S) is a noxious gas characterized by its distinctive stench reminiscent of rotten eggs. [1] It goes by several colloquial names, including sewer gas, stink damp, swamp gas, and manure gas. [2] This gas naturally occurs in crude petroleum, natural gas, hot springs, and certain food items.
Satellite image of burning tropical peat swamp, Borneo. In 1997 alone, 73000 ha of swamp was burned in Borneo, releasing the same amount of carbon as 13-40% of the mean annual global carbon emissions of fossil fuels. The majority of this carbon was released from peat rather than overlying tropical rainforest.
Renters at all income levels save less and have recently started cutting back on their spending due to the high cost of food, gas, energy, housing, and more.
Rice agriculture is a significant source of methane. With warm weather and water-logged soil, rice paddies act like wetlands, but are generated by humans for the purpose of food production. Due to the swamp-like environment of rice fields, these paddies emitted about 30 of the 400 million metric tons of anthropogenic methane in 2022. [97]
