The reports Norden, 2011 and
Miljødirektoratet, 2013 give an overview of results of monitoring data
in the Nordic EU countries.
There are considerable uncertainties as to
whether reported concentrations were above the LOQ or not as LOQ was not
Air samples: In summary, EBP was detected at
very low amounts. The report states that there was 20-40% error in the
This level of error may affect the
significance of findings reported as being >LOD.
STP sludge: 4.5 to 160 ng/d dw
Sediment in Urban harbor areas: 5 of 11
samples < LOD, others very low: 0.042 to 1.6 ng/g dw. LOQ is not stated.
Eggs: not stated if the shell was removed,
uncertain results. Results < LOD to .45 ng/g f.w most below1 ng/g fw
Fish muscles: not clear if skin was removed
and contamination from the outsode coudl have occurred: Only LOD stated.
It is not clear if any of the concentrations reproted was > LOQ. In any
case they were very low. All below 0.16 ng/g d.w.
Fish liver: data reporting with regard to
LOD and LOQ is contradictory. 6 of 7 data were reported to be < LOQ one
was reported with a value of 0.092 ng/g f.w. while to LOQ is stated to
be ).54, 1 or 1.6 ng/g f.w..
More recent data are summarized in the
literature overview "2019 update". The European data available for
birds’ eggs and fish muscle and liver were either detected in the the
pg/g range or below LOD. This is not inconsistent with the earlier
In addition to birds’ eggs and fish muscle
and liver, data are also available for shellfish at the
local marine scale (<0.84 pg/g ww - 20.1
pg/g ww and 29 ± 50 pg/g), zebra mussel and
zooplankton (both <LOD) at the local scale,
and bird liver (<0.025 ng/g ww), seal blubber
(<0.12 - 0.30 ng/g ww, more than 80% < MDL)
and polar bear adipose tissue (<0.13 ng/g ww)
at the continental background scale. Data
are also reported for tree bark (<LOD – 3.9 ng/g lipid
weight, or 0.13 ng/g using reported lipid
House dust: values of 12 ro 150 ng/g are
reported, but they are bound to polymer matrices.
In conclsion very low levels have been
detected so far in the monitoring programs and are consistent with
modelled exposure estimates.
