Monitoring data
Administrative data
- Endpoint:
- monitoring data
- Type of information:
- migrated information: read-across based on grouping of substances (category approach)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Member states reported data on monitored zinc 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.
Data source

- Reference Type:
- study report
- Title:
- Unnamed
- Year:
- 2 009

Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Member states were asked by the EU Commission to report monitored data on substances in water, that were to be relevant for assessing the general quality of the waters. Data were processed by the International Office of Water and INERIS. Data are from the period 2000-2008.
- GLP compliance:
- not specified
- Type of measurement:
- other: data reflect general water quality
- Media:
- surface water
Test material

- 231-175-3
- EC Name:
- Zinc
- Cas Number:
- 7440-66-6
- Molecular formula:
- Zn
- IUPAC Name:

- Remarks on result:
- other: dissolved concentration, 104 stations. 90P is related to monitoring of industrial point sources and mining areas, as well as to local metal-enriched geology
- Country:
- Slovenia
- Location:
- country 90P
- Substance or metabolite:
- substance
- Conc.:
- 6.3 µg/L
- Remarks on result:
- other: dissolved concentrations, 19 stations
- Details on results:
- "dissolved fraction" (= dissolved ) zinc concentrations from the period 2000-2008 are reported. Country 90P values calculated from <30 stations are not statistically reliable. In some countries (germany, Italy, Romania, sampling points are influenced by industrial point source emissions, and/or emissions from historical mining, and/or local metal-enriched geology.
Value for Spain is not reported because major problems with the definition of the fraction was observed. For nthis reason, the overall 90P for the EU cannot be recalculated and reported, neither.
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 dissolved zinc concentrations in watercannot be calculated, because of methodological errors in the Spanish dataset. the 90P values for the indivuidual countries are given in the results section.
