INTRODUCTION
The Norwegian Pollution Control Authority
(SFT) has commissioned a literature study of the
33 priority substances in the Water Framework
Directive (WFD). SFT also added 8 substances
with special interest for Norway. The study has
been conducted within a limited time frame, and
is a compilation of available literature on the
substances. No new research has been performed.
CAS Substance Need for screening
A study of the priority substances of the Water Framework Directive
TA-2140/2005
The study has been commissioned by the SFT
for three main reasons:
1. It is designed to provide an overview of all
monitoring in Norway of the 33 substances on
the WFD list.
2. It will provide much needed background
information for important decisions on which
substances that will be included in new monitoring
and screening programmes and which
matrix's should be investigated.
85535-84-8 C10-13-chloroalkanes There is a need for further screening of SCCA in marine and fresh water
sediment as well as in biota.
470-90-6 Chlorfenvinphos There is a need for new screening of chlorfenvinphos in rivers and streams.
107-06-2 1,2-Dichloroethane Further screening may be necessary around the Hydro Rafnes plant in
Grenland.
117-81-7 Di(2-ethylhexyl)phthalate
(DEHP)
DEHP should be screened in marine and fresh water sediment and in
marine and fresh water biota.
87-68-3 Hexachlorobutadiene There may be a need for screening close to three different industrial sites.
34123-59-6 Isoproturon The levels found in Norwegian environment are low, but data are very limited.
Isoproturon should be included in future screening of both marine
and fresh water environment.
25154-52-3 Nonylphenols (incl. 4-
(para)-nonylphenol)
1806-26-4 Octylphenols (incl. paratert-octylphenol)
Nonylphenol and nonylphenol ethoxylates should be screened again in
marine sediments. In addition, screening should be done in fresh water
sediment and marine and fresh water biota.
Octylphenols should be screened together with Nonylphenols, at the same
localities.
608-93-5 Pentachlorobenzene There is no need for a screening of pentachlorobenzene, but the substance
should be investigated in connection with Lindane monitoring.
87-86-5 Pentachlorophenol PCP in construction wood and pallets are monitored in Denmark. PCP in
such wood should be screened, in order to asses the risk of dioxin emissions
from incineration of pallets and construction wood, as biofuel is
excluded from waste incineration regulations, and does not have to use
filters to clean emissions. There is also a need for screening of PCP in
Norwegian environment. This screening should be done on places where
PCP pollution should be expected, such as wood treatment plants, window
production plants etc.
12002-48-1 Trichlorobenzenes (incl.
1,2,4-Trichlorobenzene)
Trichlorobenzene should be screened in marine and fresh water sediment
and biota.
Chromium Chromium should be screened in marine sediments.
Arsenic Arsenic should be screened in marine sediments and in marine biota. It
should also be screened in fresh water biota.
MCCP MCCP was screened in 2003. This screening should be repeated within a
few years in order to get a trend.
PFAS There is a need for screening of PFAS close to producers of greaseproof
paper.
