Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

Endpoint:
monitoring data
Type of information:
migrated information: read-across based on grouping of substances (category approach)
Adequacy of study:
key study
Study period:
2007-2009
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
Member states reported data on monitored concentrations to the EU Commission that were supposed to be relevant for general water and sediment 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.

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 sediment, that were to be relevant for assessing the general quality of the sediment. Data were processed by the International Office of Water and INERIS.
GLP compliance:
not specified
Type of measurement:
other: data reflect general sediment quality

Test material

Constituent 1
Chemical structure
Reference substance name:
Cadmium
EC Number:
231-152-8
EC Name:
Cadmium
Cas Number:
7440-43-9
Molecular formula:
Cd
IUPAC Name:
cadmium
Details on test material:
Data were reported for "cadmium". So, no distinction was made between different sources/forms of cadmium resulting in the final measured concentration.

Study design

Details on sampling:
data were compiled for 446 sampling stations throughout the EU, on a total of 720 analyses. Data are from the period 2000-2008.

Results and discussion

Concentration
Country:
other: EU
Location:
90P for the EU as a whole
Substance or metabolite:
substance
Conc.:
0.133 mg/kg dw
Remarks on result:
other: 2mm fraction concentration
Details on results:
Data are reported from the period 2000-2008. In some countries (e.g. 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 sediment quallity in the EU. 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 sediment quality, but rather the local situation.
Executive summary:

The overall EU 90P value for cadmium concentrations in sediment, based on 446 sampling stations, is 0.133 mg Cd/kg DW.
