(b) That a much larger network of not less than 100 stations be set up, with the 
consent of the States involved, for monitoring properties and constituents of the 
atmosphere on a regional basis and especially changes in the distribution and 
concentration of contaminants; 
(ec) That these programmes be guided and co-ordinated by WMO; 
(d) That WMO, in co-operation with ICSU, continue to carry out the Global 
Atmospheric Research Programme, and if necessary establish new programmes to 
understand better the general circulation of the atmosphere and the causes of 
climatic changes whether these causes are natural or the result of man’s activities. 
81. It 7s recommended that WHO, together with the international organizations 
concerned, continue to study and establish primary standards for the protection 
of the human organism, especially from pollutants that-are common to air, water 
and food, as a basis for the establishment of derived working limits. 
$2. It is recommended that increased support be given to the Codex Alimentarius 
Commission to develop international standards for pollutants in food and a code 
of ethics for international food trade, and that the capabilities of FAO and WHO 
to assist materially and to guide developing countries in the field of food control 
be increased. 
83. It is recommended that the appropriate UN agencies develop agreed pro- 
cedures for setting derived working limits for common air and water contaminants. 
84. It is recommended that Governments make’ available, through the Inter- 
national Referral System established in pursuance of recommendation 101 of 
this Conference, such information as may be requested on their pollution research 
and pollution control activities, including legislative and administrative arrange- 
ments, research on more efficient pollution control technology, and cost-benefit 
methodology. 
85. It is recommended that any mechanism for co-ordinating and stimulating 
the actions of the different UN organs in connection with environmental problems 
include among its functions: 
(a) Development of an internationally accepted procedure for the identification 
of pollutants of international significance and for the definition of the degree and 
scope of international concern; 
(b) Consideration of the appointment of appropriate inter-governmental 
expert bodies to assess quantitatively the exposures, risks, pathways and sources 
of pollutants of international significance; 
(c) Review and co-ordination of international co-operation for pollution control, 
ensuring in particular that needed measures shall be taken and that measures 
taken in regard to various media and sources shall be consistent with one another; 
(d) Examination of the needs for technical assistance to Governments in the 
study of pollution problems, in particular those involving international distribu- 
tion of pollutants; 
(e) Encouragement of the establishment of consultation mechanisms for speedy 
implementation of concerted abatement programmes with particular emphasis on 
regional activities. 
86. It is recommended that Governments, with the assistance and guidance of 
appropriate UN bodies, in particular the Joint. Group of Experts on the Scientific 
Aspects of Marine Pollution: ) 
(a) Accept and implement available instruments on the control of the maritime 
sources of marine pollution; 
(b) Ensare that the provisions of such instruments are complied with by ships 
flying their flags and by ships operating in areas under their jurisdiction and that 
adequate provisions are, made for reviewing the effectiveness, of, and: revising, 
existing and proposed international measures for control marine pollution; 
(c) Ensure that ocean dumping by their nationals anvwhere, or by any person in 
areas under their jurisdiction, is controlled and that Governments shall continue 
to work towards the completion of, and bringing into force as soon as possible of, an 
over-all instrument for the control of ocean dumping as well as needed regional 
agreements within the framework of this instrument, in particular for enclosed and 
semi-encloséd seas, which are more at risk from pollution; 
(d) Refer the draft articles and annexes contained in. the reports of the inter- 
governmental meetings at Reykjavik, Iceland, in April 1972 and in Londonin May 
1972 to the UN Committee on the Peaceful Uses of the Seabed and the Ocean 
Floor beyond the Limits of National Jurisdiction at its session in July/August 1972 
for information and comments and to a conference of governments to be convened 
by the Government of the United Kingdom of Great Britain and Northern Ireland 
in consultation with the Secretary-General before November 1972 for further con- 
sideration, with a view to opening the proposed convention for signature at a place 
to be decided by that conference, preferably before the end of 1972;
