Abstract
As part of a project investigating the air-water exchange of nutrients and inorganic micropollutants to the North Sea, the atmospheric deposition of n utrients and trace metals in their different compositions and via various p athways was investigated. Intensive sampling campaigns were organised on th e research vessel Belgica (ns 21/98 campaign from September 28 to October 1 , 1998 and ns 10/99 campaign from April 19 to 23, 1999), at a sampling stat ion near the Belgian coast (Knokke-Heist) and at the University campus of A ntwerp. Simulation work and remobilisation experiments were carried out to obtain a general view of the kinetics of solubilisation of the constituents under investigation. Sample treatment requires a leaching system with a qu antitative recovery of the species of interest in the leaching solution wit hin a reasonably short period of time (30 min). For this reason, a re-circulation leaching system was developed, tested, op timised and compared with a more accepted ultrasound leaching method.
