Thanks to George Fielderwho points out that methane gas is not toxic, but rather (we add) the hazards of methane gas produced by septic systems include possible explosions or the asphyxiation of someone who enters or even just leans over a septic tank opening. (email 10/20/2007) "7 Killed...
This passage preliminarily studied the law of unusual gush of gob gas of the fully mechanized caving mining. According to the basic condition for the gas explosion, made comprehensive analysis and appraisal about the oxygen condition, gas concentration distribute and fire source conditions. And find ...
Landfill gas is produced by bacterial decomposition of organic waste. This process happens in several stages, with each stage bringing new dangers as different gases are produced. The main components of landfill gas are methane (CH4) and carbon dioxide (...
You should not allow methane (sewer gases) to accumulate in a building as (depending on the concentration of methane present) the building can be blown up by a spark or flame. Details are at inspectapedia.com/septic/Methane_Gas_Hazards.php Human exposure limits for methane gas (figure sewer...
— Our results show that genistein (a) inhibits the decatenation activity of DNA topoisomerase II and (b) stimulates DNA topoisomerase II-mediated double strand breaks in pBR322 DNA on sites different from those of 4'-(9-acridinylamino)methanesulfon-m-anisidide, etoposide, and 2-methyl-9-...
Divided the gob gas in different types according to falling structure and spatial patterns of gob of the fully mechanized caving mining and analyzed its main form of harm.This passage preliminarily studied the law of unusual gush of gob gas of the fully mechanized caving mining. According to ...
Dangers of Shale Gas DrillingThe article discusses methane concentrations found in water wells near shale gas drilling sites where a process called hydrofracking is used to get access to the gas.Walsh, BryanTime
