Appearing in the journal Nature, (http://www.nature.com/nature/journal/v544/n7648/full/nature22030.html) the paper estimates the growth in photosynthesis "based on long-term atmospheric carbonyl sulfide (COS) records, derived from ice-core, firn and ambient air samples." Its findings are consistent with the figures used in climate models, including the assessment by the Intergovernmental Panel on Climate Change.
In the case of environmental air pollutants like carbon monoxide, oxides of nitrogen (NOx), sulfur dioxide (SOx), reduced sulfur like hydrogen sulfide ([H.sub.2]S) or carbonyl sulfide (COS), and now carbon dioxide (C[O.sub.2]), the EPA and other environmental-regulating agencies dictate that calibration standards be produced to a known method, EPA 600/R-12/531.
Organic sulfur contains carbonyl sulfide (COS), carbon disulfide ([CS.sub.2]), thiophene, mercaptan, and so forth [1].
It contains a biologically very active, absorbable gaseous compound, the carbonyl sulfide (COS) which transforms into hydrogen sulfide.

The current crisis with defective Chinese drywall that is diffusing low levels of sulfur compounds like hydrogen sulfide, carbonyl sulfide, carbon disulfide and others creates a serious concern as to the method of remediation.
The technology, which will be marketed under the brand name PuraTreat A, has excellent properties to selectively remove sulphur compounds such as hydrogen sulfide or carbonyl sulfide from synthesis gas streams based on coal.
The material can completely remove carbonyl sulfide, a capability currently not offered by traditional nickel-based catalysts.
Beverage-grade C[O.sub.2] can contain an array of impurities, including sulfur gases (carbonyl sulfide, hydrogen sulfide and sulfur dioxide), hydrocarbons (acetaldehyde, benzene and light hydrocarbons), oxygen and moisture.
Sulfur, however, has to be removed from the mixture in the form of hydrogen sulfide ([H.sub.2]S) and carbonyl sulfide (COS) to protect process equipment and meet environmental regulations.
1, 2002) to two NIST scientists for a process that selectively removes carbonyl sulfide, a potentially problematic impurity, from liquefied petroleum gas (LPG).
The emissions may be carbon disulfide ([CS.sub.2]) and carbon oxysulfide (also known as carbonyl sulfide, formula COS).
