Scottish Marine and Freshwater Science Volume 5 Number 15: Development of a Sampling Programme and Measurement of Contaminants in Food for Marine Strategy Framework Directive Descriptor 9

Descriptor 9 (contaminants in food) is one of eleven Marine Strategy Framework Directive (MSFD) qualitative Descriptors to be used in determining whether Good Environmental Status (GES) has been achieved for European regional seas (Directive EC/2008/56).

ii. Dioxins (sum of polychlorinated dibenzo-para-dioxins ( PCDDs) and polychlorinated dibenzofurans ( PCDFs), expressed as World Health Organisation ( WHO) toxic equivalent using the WHO-toxic equivalency factors ( WHO- TEFs).

iii. Of the 209 PCB congeners, the most toxic are the so-called 'dioxin-like' PCBs ( DL-PCBs). The DL- PCBs are the four non- ortho ( CB77, 81, 126, and 169) and eight mono- ortho ( CB105, 114, 118, 123, 156, 157, 167, and 189) congeners. DL-PCBs are stereo-chemically similar to 2,3,7,8-tetrachlorodibenzo- p-dioxin ( TCDD) and, therefore, have similar toxic and biological responses to those of dioxins.

iv. The seven ICES (International Council for the Exploration of the Sea) PCBs ( CB28, 52, 101, 118, 153, 138, and 180) were recommended for monitoring by the European Union Community Bureau of Reference; these congeners were selected as indicators of wider PCB contamination due to their relatively high concentrations in technical mixtures and their wide chlorination range (3-7 chlorine atoms per molecule). The ICES 7 PCBs have been part of the OSPAR Co-ordinated Environmental Monitoring Programme ( CEMP) since 1998. MPCs have been set for the ICES 6 (excludes CB118 which is classed as a DL-PCB).

v. Metals (cadmium, mercury and lead) in sediment and biota ; PAHs (anthracene, benz[ a]anthracene, benzo[ ghi]perylene, benzo[ a]pyrene, chrysene, fluoranthene, indeno[1,2,3- cd]pyrene, pyrene and phenanthrene) in biota and sediment; PCBs ( ICES7- CB28, 52, 101, 118, 138, 153 and 180) in biota and sediment; brominated flame retardants (hexabromocyclododecane ( HCBD) and BDE28, 47, 66, 85, 99, 100, 153, 154 and 183 in biota and sediment, and BDE 209 in sediment).

vi. This is the MPC from 1881/2006, this was amended to 6.5 pg g -1 TEQ wet weight in 1259/2011
