Monitoring programme: ContaminantsProgramme topic: Concentration of contaminants
The monitoring of this sub-programme is: partly coordinated
Common monitoring guidelines in
ISO/IEC 17025, Guidelines for determination of chlorinated hydrocarbons in sediment, Guidelines for determination of PAH in sediment and other
Common quality assurance programme: HELCOM COMBINE manual,
ISO/CEN standards and
MORS Guidelines defines methodologies for sample treatment, analysis and intercomparison. Reported data is manually quality assured by the HELCOM Secretariat and results are reported and verified in annual MORS EG meetings.
Common databases: COMBINE,
There is no current plan for coordinated monitoring of contaminants in sediments, other than radionuclides. Under the Water Framework Directive, no EQS values have so far been set in sediments. However, countries are encouraged to perform long term trend analysis of concentrations of persistent substances that tend to accumulate in sediment, in order to ensure that such concentrations do not significantly increase (such as Hg, PAHs, HCHs, HCB, PBDE, TBT, PCB, PFOS, PCDD/F, HBCDD).
Concentrations of hazardous substances close to natural levelsRadioactivity at pre-Chernobyl level
Other features:A description of the situation with regard to chemicals, including chemicals giving rise to concern, sediment contamination, hotspots, health issues and contamination of biota (especially biota meant for human consumption)
Measured in: Kiel Bay, Kattegat, Southern Baltic Proper, Great Belt, Bay of Mecklenburg, Little Belt, The Sound.
See map for details
Measured in: Bay of Mecklenburg, Southern Baltic Proper, Kiel Bay, Kattegat, The Sound, Great Belt, Little Belt.
All other contaminants in sediment are measured in: Kiel Bay, Kattegat, Southern Baltic Proper, The Sound, Great Belt, Bay of Mecklenburg, Little Belt.
For CEMP: furans are monitored in: Kattegat and Skagerrak, TBT only in Kattegatt.
National monitoring is only reported for Denmark and Germany, of which furans are monitored in Great Belt, Kiel Bay, Little Belt.
TBT is measured in Bay of Mecklenburg, Kiel Bay, Little Belt, Great Belt. Metals are reported from Great Belt Kiel Bay Bay of Mecklenburg Little Belt.
All the remaining national contaminants data is reported from Great Belt, Kiel Bay, Bay of Mecklenburg and Little Belt.
Obligatory radionuclides: Gamma-emitters: K-40, Cs-137 and other γ-emitters identified in the γ-spectrum.
Voluntary radionuclides: Sr-90; Pu-239, 240; Am-241; natural radionuclides (e.g. Po-210).
Monitoring is to be carried out to fulfill assessment requirements of HELCOM ecological objectives that are specified through HELCOM core indicators. The requirements on monitoring can
include number of stations, the sampling frequency and replication.
Monitoring should provide adequate data and information to enable the periodic assessment of environmental status, and distance from and progress towards GES as required by MSFD under Article 9 and 11.
