Conclusions
Analytical standard methods for 32 of 33 compounds/compound groups are available
Method performance data do not match all EQS proposals for inland waters and marine waters
Inland Water: Lower method application range /proposed EQS
For 21 of 31 substances methods sufficiently sensitive
(lower method application range /proposed EQS < 1)
For 5 of 31 substances Factor 1- 2
For 3 of 31 substances Factor 2 – 3.5
For 2 of 31 substances Factor > 3.5
Chlorpyrifos (-ethyl, -methyl) Factor 22
Tributyltin compounds Factor 100
Marine Water: Lower method application range /proposed EQS
For 19 of 29 substances methods sufficiently sensitive
(lower method application range /proposed EQS < 1)
For 3 of 31 substances Factor 1- 2
For 4 of 31 substances Factor 2 – 3.5
For 4 of 31 substances Factor > 3.5
Chlorpyrifos (-ethyl, -methyl) Factor 22
-HCH Factor 5
Benzo[K]fluoranthene Factor 18.5
Tributyltin compounds Factor 100
Need of aquatic reference materials for QA/QC
No information on cost of monitoring:
only 2 contributions, no sampling costs
No harmonised method for chloroalkanes available
21 of 33 substances are covered by methods from 2000/2001/2002
Not all methods are up-to-date
Conclusions
Conclusions
Use of alternative methods is desired by AMPS members
The use of standard methods alone does not guarantee comparable data across Europe
Need for standard/reference methods as guidelines and for definition of analytes
Longterm need for a European proficiency testing scheme
Identification of data quality requirements necessary
Drafting group on data quality requirements
New analytical methodsStill problematic:•PBDE
•SCCP
•Alkylphenols
•Phthalate
Document should be further commented, developed and should present an overview on still remaining problems in method development for WFD PS
Need for further method development, testing and interlaboratory comparisons
Natural metal background concentrations
No harmonised method for deriving geogenic metal background concentrations in water is currently available
General agreement with proposal for metal EQS setting
Drafting group on metal background concentrations
Suspended Particulate Matter/Sediment/Biota Monitoring
MS/CC have more experience with sediment
SPM sampling not in all water types possible
Discussion on feasibility of different approaches
Need to identify different monitoring needs for different water types ?
Background documents to be provided
Future AMPS tasks
Support to review of PS list
Contact between Marine and Inland monitoring is established (ICES) and needs to be enhanced
Coverage of Mediterranean area ?
Non target methods for river basin specific contaminants
AMPS 2 Actions
Background documents on SPM/Sediment/Biota monitoring will be provided
Drafting group: Metal background concentrations
Drafting group: Data quality objectives/requirements
Additional AMPS (3) meeting in April
AMPS 2 minutes still need to be commented by members !
