A detailed per-element list can be found in this article:

http://www.answersingenesis.org/articles/arj/v3/n1/sodium-chloride-abiogenesis

See table 1 there.

Yes, that's a creationists' page, and the quoted paper appears to be a 
creationist's, too, but I see no reason to doubt the numbers they're 
quoting, as the general order of magnitude appears to match numbers from 
Wikipedia:

(1) The salinity of blood can be inferred from that of medical "normal 
saline" solution:

"The solution is 9 grams of sodium chloridre (NaCl) dissolved in water, 
to a total volume of 1000 ml. [...]. It has a slightly higher degree of 
osmolarity (i.e. more solute per litre) than blood [...]."

(http://en.wikipedia.org/wiki/Isotonic_saline#Normal)

(2) The salinity of salt water is given expressively:

"Seawater has a salinity of roughly 35,000 ppm, equivalent to 35 grams 
of salt per one liter (or kilogram) of water."

(http://en.wikipedia.org/wiki/Saline_water)

Never heard of minerals being washed down by rain into the oceans?
