This paper summarizes the chemical characterization of PM 10 obtained from 38 sampling campaigns carried out in 16 sites in Italy during the years 2008–2018. Chemical determinations include all macro-components (six macro-elements, eight ions, elemental carbon and organic carbon). The sum of the individual components agrees well with the PM
Calcium-binding properties and molecular …
Calcium was shown to bind to the peptide with a dissociation constant Kd = 2.8 + 0.2 mm. 2Pro and 3Pro carbonyls, as well as the 9Arg carboxyl, were assigned as the metal-binding sites. A molecular model of the 1 : 1 metal-complex was obtained.

Aragonite: The mineral aragonite information and …
Calcium carbonate forms as both Aragonite and Calcite, and these two minerals only differ in their crystallization.Calcite, the more common mineral, forms in trigonal crystals, whereas Aragonite forms orthorhoic crystals. On occasion, crystals of Aragonite and Calcite are too small to be individually determined, and it is only possible to distinguish these two minerals with optical or x-ray

Chemical properties of water in a flooded opencast …
The chemical properties of water in the only flooded sulphur opencast mine in the world have been analysed. The reservoir has a depth of 22 m and is still continuously pumped, which affects the deeper tertiary aquifer. Instead of quaternary water being pumped out, tertiary water flows into the reservoir. Mineralisation of the water in this reservoir varied from 2000 to 10,000 mg dm−3 near
