Composition of Sea Water

[arsmith]

Can any one out there give me the Chemical Composition of Sea Water (aproximate) ,I mean the salts disolved in it in ppm

 

[Metalguy]

Usually the main concern is with Cl, which is ~20,000+ PPM, depending on the ocean. There's also a few thousand PPM sulfate, IIRC.

My CRC Handbook of Chemistry and Physics has 2 tables for the composition of seawater:
a) By elements (81 are listed),
2) By major ions (13).

This is one of the best on-line listings by ionic makeup, listed in order of decreasing composition:

This gives the total composition of seawater, with 1st the few major components, then for all the elements (in order of atomic weight) :

As an example, the Composition OF Arabian Gulf seawater:

Cations:
sodium 13440 ppm
potasium 485 ppm
calcium 520 ppm
copper 0.004 ppm
iron 0.008 ppm
strantium 1 ppm
boron 3 ppm

Anions:
chloride 24050 ppm
sulfate 3380 ppm
biocarbonate 165 ppm
carbonate 88 ppm
bromide 1 ppm
TDS 42528 PPM
pH 82 ppm

Note the concentration varies from season to season and from site to site.

somebody know some measure for saltwater intrusion
