Applicant's summary and conclusion

Conclusions:
test done according to standard protocol, useful to assess the characteristic of the substance
Executive summary:

Data reported for coastal water before the Dutch coast; Worst case for Europe, because of presence of mouth of several major rivers. Observed zinc levels (90P dissolved) range between 1.0 and 1.7 µg/l.
