what percent of dissolved salts found in seawater are minor inorganic salts, or trace?

Seawater varies in composition a little but generally is about 3.5% salts. Of this about 3.1% is sodium chloride. So the remaining 0.4% is the other salts (Magnesium, Calcium and Potassium mostly, followed by just about every natural element in the periodic table in trace amounts)
