Substructure information is of great relevance for metabolomics experiments involving MSn data, where often the only information available of an unknown metabolite that needs to be identified is the elemental composition and in some cases substructures.
Therefore elemental mercury needs to be detected and removed at its point source before it can be converted into the more toxic compounds.
While with OMG only the elemental composition needs to be provided to generate molecules with multiple valences, MOLGEN requires knowing a priori which one of the multiple valences has to be used.
However, the mass-bias contributions by instrumental mass discrimination and laser-induced elemental fractionation need to be determined independently.
If it transpires that copernicium and flerovium are gaseous metals at or near room temperature, as some calculations have suggested, the category of elemental gases may need to be sub-divided into metallic and nonmetallic gases.
How the ROS-stimulating potential of PM may be linked mechanistically to the increased mortality is unclear, but it seems that the contribution of factors other than the elemental composition would need to be considered.
As the recovery gathered pace, Elemental identified public buildings that needed to be rebuilt, or constructed from scratch, to enhance the city – including the fire station and bus station, plus a public theatre, school, public library and cultural centre.
However, the phytochemical, elemental and toxicological studies of this potential antihypertensive still needed to be investigated.
Elemental analysis is useful for the quantitative analysis of the components of calcium phosphate crystals but the crystals need to be dissociated prior to this type of assay.
"That's when I began to want things to be more elemental," she says.
