Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Remarks:
Member states reported data on monitored concentrations to the EU Commission that were supposed to be relevant for general water quality. However, analysis has demonstrated that the data were not always answering that definition. Still, this data review was at EU scale was unique and is therefore reported.

Details on results:
"whole water" (= total) zinc concentrations are reported from the period 2000-2008.. Country 90P values calculated from <30 stations are not statistically reliable. In some countries (Cyprus, Romania, Slovakia, sampling points are influenced by industrial point source emissions, and/or emissions from historical mining, and/or local metal-enriched geology.

Applicant's summary and conclusion

Conclusions:
Given the scale and recent date of the study, the results are considered relevant for assessing current water quallity. It has to be noted that for several countries, the dataset contains data from sampling sites, specially chosed to monitor emissions from industrial point sources. As such, the data do not always reflect general water quality, but rather the local situation.
Executive summary:

The overall EU 90P value for total zinc concentrations in water, based on 5881 sampling stations, is 32 µg Zn/l.

Individual country data are given in the "results" section.
