Directive 76/464/EEC isthus aframework directive which must be
implemented bymeans ofsubsidiary directives inrespect ofsub­
stances contained inList I.
These subsidiary directives mainly concern direct industrial dis­
charges into theaquatic environment .However ,incertain cases it
will benecessary todevise acomprehensive approach inorder to
eliminate pollution caused bycertain disubstances discharged into
the different environments (water ,air,soil )orbyindirect or
diffuse discharges .
2. Choice sofar ofpriority List Isubstances
With theexception ofmercury and cadmium ,List Iintheannex to
the Directive of4May 1976 referred toabove does notmention
individual substances ,but families orgroups ofsubstances (for
example organohalogen compounds etc .).
Itwill therefore benecessary tochoose certain individual suby
stances from among the families orgroups inorder tostudy them
and,ifappropriate ,prepare proposals forthe Council .The
Directive states that these substances must beselected mainly on
thebasis oftheir toxicity ,persistence andbioaccumulat ion .
Following theadoption oftheDirective of4May1976 the services
ofthe Commission began the choice ofindividual priority sub­
stances from List I. Inthis itwashelped byagroup ofnational
experts ,which hasmet five times .
During these meetings four series ofsubstances have been chosen .
These have been studied bytheservices oftheCommission ,and
several are thesubject ofproposals tothe Council which have
been ,orarebeing ,prepared .List Ialso includes carcinogens ,
some ofwhich arealso being examined bytheservices ofthe
Commission .Thesubstances selected andtheprogress ofthework
onthem are shown inTable 1.

Several other lists ofsubstances presenting risks totheaquatic
environment were also taken into account inthis work .
Thus onecould cite theEPA (Environmental Protection Agency -USA )
1 . .2List oftoxic pollutants andList ofhazardous substances ,the
Canadian list (List ofpriority chemicals 1979^)andtheGerman
catalogue ofsubstances constituting arisk totheaqueous
4envi ronment (Utowedtbundesamt ,1980 ).
Furthermore ,the International Commission fortheProtection ofthe
Rhine against Pollution recently drew upalist ofdangerous sub­
stances for that watercourse .The Services ofthe Commission parti­
cipated inthis work and was thus able tonote specific information
and data oncertain substances ofmore particular interest tothe
ripairian countries ofthat river .
The Services ofthe Commission have drawn upaprovisional list of
122 substances onthe basis ofthe various lists ofsubstances and
onthe studies referred toabove .This List has been sent tothe
Member States with aview toobtaining additional information on,
inparticular ,thequantities produced ,consumed anddischarged in
theaquatic environment byeach Member State .
This additional information wasexamined atameeting ofnational
experts ,thus enabling alist of108substances outof122tobe
drawn up.
Since the 108 substances selected could not beexamined simultaneously ,
itwasagreed atthis meeting tochoose 15substances tobestudied
first .

When one adds tothis List of108 substances the 21substances which
were chosen earlier andwhich have already been studied (seeTable 1,
page 3)oneobtains thecomplete list of129substances towhich
this Communication relates .
List ofsubstances
The List isannexed tothis Communication .
Within this list itisnecessary todistinguish four categories of
substances inrelation totheprogress made inthework :
1.7substances ,indicated by***arealready the subject ofa
proposal oraCommunication tothe Council ;
2.14substances ,indicated by**, areunder study orhave been
studied ;
3. 15substances ,indicated by*,will bestudied inthe near
future ;
4.93substances will bestudied subsequently .
The Chemical Abstract Service number (CAS )has been added tothe
substances inorder that they might bemore easily identified .
The Commission does not consider this list tobefinal and exhaustive .
Itplans toreview it,ifappropriate ,inthe light ofnewscientific
knowledge and totake account ofanyother substances which might be
produced orused infuture .

Conclusions
TheCommission askstheCounciltotakeformalnoteofthis

Itconsiders furtherthatthesesubstances shouldbeincludedin
