Atmospheric input of anthropogenic phosphorus to the northwest Mediterranean under oligotrophic conditions

Résumé

Phosphorus (P) concentration in the atmospheric aerosol was measured at a northwestern Mediterranean coastal site. Airborne P ranged between 25 and 85 ng m(-3) (geometric mean: 51 ng m(-3)). Due to a significant contribution (about 90%) of anthropogenic land-based source emissions, dry deposition velocities of 0.1-0.5 cm. s(-1) were used to estimate a dry flux of 0.15-0.7 mu mol P m(-2) day(-1). The theoretical impact of the dry flux on primary production (0.1-0.4 mg C m(-2) day(-1)) is 50-200-fold lower than that of a single significant wet event. The incineration plant of the Nice district is identified as a possible major source of airborne anthropogenic P. As the implementation of waste plants is currently expanding along the western European shores, the importance of the P atmospheric source to the western Mediterranean is likely to increase with time.
