Transition elements & organo-metal e.g. Chromium, Copper, TBT) contamination. Includes those priority substances listed in Annex II of Directive 2008/105/EC.

These standards provide good levels of protection for all living organisms where standards are adhered to.  For marine sediments the main elements of concern are Arsenic, Cadmium, Chromium, Copper, Mercury, Nickel, Lead and Zinc Organo-metallic compounds such as the butyl tins (Tri butyl tin and its derivatives) can be highly persistent and chronic exposure to low levels has adverse biological effects, e.g. Imposex in molluscs.

Benchmark: 
Compliance with all average annual Environmental Quality Standards, or conformance with Probable Effect levels,Environment Assessment Criteria, Effects Range -Low.
Examples: 
Sources may include aquaculture (e.g. antifoulants), sewage, dredge and nuclear discharges, and other activities that may disturb contaminated sediment.
Notes: 
1. See separate pressures for transition elements and organo-metal contamination within mixing zones (acceptable area of impact) where there may be some level of risk to some features. 2. See separate pressures for transition elements and organo-metal contamination - significant pollution incidents/accidental spills and or bioaccumulation. 3. OSPAR combine all of these pressures in a single one.

The tables in this section reflect the output of the workshop (October 2019) when the pressures from human activities were assessed for the period 2014 to 2018 for the region. The summary text below the tables elaborates on some of the points that were made at the workshop.
This pressure assessment uses the FeAST classification which includes two abrasion pressures: surface abrasion & sub-surface abrasion. Some expert groups combined these as a single pressure "surface & sub-surface abrasion" whilst others focussed on using surface abrasion alone, hence there is a slight difference in handling for some regions.
The ranking of the pressures in terms of impact is a relative exercise within each region, and is not a statement of their absolute impact. Detailed comparison between regions on the basis of these relative pressure assessments is therefore not advisable.
