International action against hazardous pesticides

This article explains developments at an international level to tighten regulation against hazardous chemicals, including pesticides, and analyses what changes might result from these steps.

This year has seen significant international activity to address the problems of hazardous pesticides. The first meeting to develop a Convention for the Prior Informed Consent (PIC) procedure was held in Brussels in March. In April, government-designated experts met in Copenhagen and made additional proposals. The pressure for swift action on persistent organic pollutants (POPs), which includes nine highly persistent organochlorine pesticides, is mounting.  In Canberra in February, government delegates met under the Intergovernmental Forum on Chemical Safety (IFCS) programme to discuss this and wider chemical management issues. Where will these initiatives lead, and what progress can be expected? 

Negotiating a PIC Convention
The present voluntary PIC, which allows governments to prohibit the import of certain hazardous pesticides, is unsatisfactory in a number of respects, and Agenda 21 called for a legally-binding Convention by the year 2000.  The UN Environment Programme (UNEP) is the lead organisation(1), and FAO retains responsibility for pesticides(2).  It became clear at the first meeting of the Inter-governmental Negotiating Committee (INC) that governments have a strong preference for ‘a clean PIC’, that is minimal change, negotiated in three meetings and completed in early 1997.

Criteria for PIC
At the end of the INC meetings, there should be better guidelines for including a chemical in PIC.  To date the procedure includes only 12 pesticides, although an additional 17 are being processed and a further 15 would be included if found to be still in use.  Chemicals are candidates if they are banned, withdrawn or severely restricted by governments for health or environmental reasons. The INC confirmed that a ban by at least one country on these grounds is sufficient to become a PIC candidate. But a PIC Convention will need better criteria for identifying pesticides which are not banned, but which cause health problems under conditions of use in developing countries. Another question for the INC to resolve is whether to add a category for pesticides causing environmental problems under conditions of use as favoured by NGOs.
    The INC must decide on other issues. At present, for example, it is for governments to decide whether they notify an importing country that export of a PIC chemical is taking place from its boundaries. More countries want notification, and governments asked the secretariat to advise on this for the next session.

How far can PIC go?
The PIC procedure is helpful to importing developing countries, but it remains only a form of information exchange. Many—particularly NGOs but also some governments—believe that certain chemicals are too hazardous to be traded and would like to see an end to their production and use.  Action at this level would imply radical changes to PIC during the Convention negotiations—something for which governments have shown no enthusiasm. Alternatively, another mechanism must be developed to deal with this aspect.

The POPS negotiations
Such a mechanism is underway to cover POPs.  Concern has grown about the impact of these environmentally persistent chemicals, which cross national boundaries and accumulate in the earth and sea, particularly in northern regions: the Nordic countries and Canada are leading calls for timely action. The UN Economic Commission for Europe (UNECE) has initiated work on POPs(3) , and the UNEP Governing Council(4)  invited the UN and governments to expedite action, starting with the short-list identified by the UNECE: aldrin, dieldrin, DDT, endrin, chlordane, hexachloro-benzene, mirex, toxaphene and heptachlor (all pesticides), and PCBs, dioxins and furans which can arise as by-products of the production process.
    All the pesticides which are POPs are included in PIC. While their use has been severely curtailed compared with the situation 20 years ago, an FAO/UNEP survey(5) , indicated that most products are used, though at a minimal level.
    Work on POPs is also led by UNEP, but is located under the IFCS which is implementing the chemical programme highlighted by Agenda 21(6) . The Canberra IFCS meeting agreed that there is sufficient scientific evidence on POPs to justify international action. Swift action may follow the next meeting—in the Philippines in June—which will look at available alternatives and recommend routes for action. It seems likely that a Convention will be favoured, recommending to phase out the production and use of at least some POPs.  But governments will want to distinguish between products for which alternatives are available; products where substitutes are not readily available; and by-products of a production process, such dioxins, where the solutions may rely on cleaner technology.

But where next?
The difficulty will arise when identifying further chemicals for international action.  In Copenhagen government delegates made a distinction between international action which may be taken when local activities or emissions lead to regional or global exposure, and appropriate local or regional action for dealing with local problems. The latter might include capacity building; technology transfer; monitoring and enforcing control measures; better training; local bans or phase-outs, better information including export notifications, and import bans based on a PIC decision. But the Copenhagen meeting also revealed the depth of tension between those with an environmental agenda, and a number of governments pushing a strong and liberalised trade agenda, calling for measures which are the least restrictive on trade and stressing the need for a full cost benefit measures on possible action.
    Agencies are co-ordinating these activities, helped by the IFCS structure. There is also a clear need for consolidation, and a growing recognition among some governments that a chemical convention may be needed, into which PIC, POPs and related issues are embedded. There certainly needs to be a strong linking process between the PIC and POPs activities.
    However, while this international action is positive (if long overdue), it addresses only a small number of pesticides and in the case of POPs their use is now very limited. Good criteria for adding to the POPs could partly meet NGO demands to acknowledge that certain PIC chemicals are too hazardous to be traded or used, and should be phased out of production. But there is also a need for a parallel process focusing on pesticides giving rise to serious health problems. 
    While agreement is firm on certain widely banned pesticides, such as carcinogens and persistent organochlorines, getting firm international action on other pesticides remains a problem. There are, of course financial implications. Safer alternatives and training are more expensive. More stress needs to be placed on the health and environmental costs of pesticides, particularly as some governments stress the financial costs of alternatives. (BD)
