The tragedy, which also hospitalized several others, prompted Laotian authorities to detain eight hostel staff members and launch an investigation into the source of the contamination. Governments, including Australia, updated travel advisories, warning citizens about the dangers of consuming local alcohol in Southeast Asia.
Methane (CH 4) concentrations in the atmosphere measured by the Advanced Global Atmospheric Gases Experiment (AGAGE) in the lower atmosphere (troposphere) at stations around the world. Values are given as pollution free monthly mean mole fractions in parts-per-billion. [1] Atmospheric methane is the methane present in Earth's atmosphere. [2]
Sewer gas can contain methane and hydrogen sulfide, both highly flammable and potentially explosive substances. As such, ignition of the gas is possible with flame or sparks. [7] The methane concentration in open sewers is lower (7 to 15 ppmv) than the closed drains (up to 300 ppmv) in samples collected 2 cm (0.8 in) above the level of sewage. [8]
Previously reported methane emission estimates are also likely lower than reality, as a result of the dangerous nature of manually measuring emissions at landfills, which require workers to walk ...
Satellite data enables the identification of super-emitter events that produce methane plumes. Over 1,000 methane leaks of this type were found worldwide in 2022. [ 1 ] As with other gas leaks , a leak of methane is a safety hazard: coalbed methane in the form of fugitive gas emission has always been a danger to miners.
Russian poster warning people about the dangers of drinking methanol. In October and November 2005, 34 people in Magadan died from methanol poisoning after drinking tainted liquor. [63] In December 2016, 72 people died in a mass methanol poisoning in Irkutsk, Siberia.
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
A controlled study run by Rumin8 and University of New England found an impressive 81% reduction in methane emissions when cattle had access to water troughs treated with the tech company's ...
