Short summary
The fractions of trace elements in atmospheric particles that are soluble have been measured over the Mediterranean and Black seas. These soluble fractions can affect the growth of microorganisms in the ocean, and our results show that they are affected by mixing with pollutants from the surrounding land and shipping emissions. Atmospheric particles contribute to the loads of soluble elements found in the  surface waters and influence the balance between nitrogen and phosphorus.
