Bioaerosols and dust are the dominant sources of organic P in atmospheric particles

Abstract Several studies assessed the impact of inorganic P in fertilizing oligotrophic areas, however, the importance of organic P in such fertilization processes received far less attention. In this study, the amount and origin of organic P delivered to the eastern Mediterranean Sea were character...
