Convention on Trade in Dangerous
Chemicals and Pesticides: Final Round of Talks Started
Ninety-five countries agree on the new
international convention on dangerous chemicals and pesticides
LINDANE (C6H6CI6) Lindane is an organochlorine pesticide. It is a
colorless, crystalline solid with either a faint or no smell. It is composed of
approximately 99% HCH. Lindane has been used as a broad-spectrum agricultural
insecticide since the early 1950s and is 5-20 times more toxic to insects than
DDT. It is also used in ointments to treat head and body lice, and scabies. It
is poorly soluble in water and rapid bioaccumulation takes place in
microorganisms, invertebrates, fish, birds and humans. However, the elimination
of lindane from the body is relatively rapid when exposure is discontinued.
Lindane can remain in the air for up to 17 weeks. Workplace exposure has been
reported to cause blood disorders, dizziness, headaches, and changes in the
levels of sex hormones. The ingestion of large amounts has caused seizures and
death. Liver and kidney effects and immune suppression has been observed at
moderate ingestion levels. Lindane is considered to be a carcinogen, and has
been associated with liver cancer. The international trade of lindane will be
addressed by the PIC Convention.

Similar challenges confound identifying sources of HCH, which is one of
the most widely used insecticides in the world (2, 14).
The technical mixture contains 60-70% -HCH,
5-12% -HCH,
10-12% -HCH,
and other isomers (2). Only -HCH
is insecticidal, but the other isomers have toxic properties, particularly -HCH,
which is more bioaccumulative and is a possible environmental estrogen (2).
Canada, the United States, and European countries have banned technical HCH in
favor of using pure -HCH
(lindane), but large quantities of technical HCH were used in Asia throughout
the 1980s and to a lesser extent into the 1990s (14).
The atmospheric signal today consists of lindane superimposed on a background of
technical HCH, and elevated ratios of -HCH/-HCH
indicate episodic transport of lindane from regions of current use (2).
A difficulty with interpreting this ratio is that the two isomers are removed
from the atmosphere at different rates during transport, possibly due to
differences in air-sea exchange or photolysis rates (2).

Convention on Trade in Dangerous Chemicals
and Pesticides: Final Round of Talks Started
BRUSSELS/NAIROBI, 9 March 1998
- More than 100 countries are expected to conclude negotiations this week on a
legally binding Convention on international trade in hazardous chemicals and
pesticides.
The intergovernmental meeting started today in Brussels and will finish on
Saturday, 14 March, the United Nations Environment Programme (UNEP) and the Food
and Agriculture Organization (FAO) announced today.
The new legally binding treaty will limit the trade in hazardous chemicals
and pesticides such as PCBs, Lindane, Aldrin, Dieldrin and harmful pesticide
formulations including substances such Monocrotophos and Parathion.
The trade in extremely hazardous chemicals and pesticides is currently
subject to the voluntary Prior Informed Consent procedure (PIC) in which 154
countries are participating. It is jointly administered by FAO and UNEP.
Under PIC, 22 harmful pesticides and five industrial chemicals that have been
banned or severely restricted in a number of countries should not be exported
unless agreed by the importing country. The Convention will replace the current
voluntary system.
Countries agreed during previous negotiations that the substances subject to
the voluntary PIC procedure will be included in the Convention. The Convention
will legally require exporters to notify recipient countries of exports of
hazardous substances subject to national bans or severe restrictions.
It is expected that additional industrial chemicals and pesticides will be
added to the PIC procedure. In the European Union, the PIC procedure is already
mandatory and violators can be fined.
Many chemicals and pesticides are harmful to humans, domestic animals and
ecosystems. They may cause cancer or birth defects, or enter the food chain and
accumulate in the tissues of people or animals. Chemicals such as asbestos which
is still exported around the world are now known to be carcinogenic.
According to UNEP, the past use and trade of these chemicals has left a
legacy of lasting problems. Several PIC substances whose use has been banned and
phased out in industrialized countries are still widely used in developing
countries and in countries with economies in transition. DDT continues to be
released into the environment where it poisons wildlife.
Polychlorinated biphenyls (PCBs) are highly toxic to humans and are found in
the blood and tissue samples of people thousands of kilometers from where these
chemicals were released. Every day scientists discover previously unknown
dangers posed by certain chemicals. A PIC treaty is thus vital for reducing the
risk to the world's health and environment.
FAO warned that many pesticides, such as DDT, chlordane and heptachlor, which
have been banned or whose use has been severely restricted in Europe and North
America, are still marketed and used in developing countries. Also, many old,
often highly toxic, organophosphorus pesticide formulations continue to be used
there because of their low price.
The global market for pesticides continues to grow and is estimated at $30
billion for 1996. Companies based in Western European are currently the world's
largest chemical producers. The fastest growing markets are in developing
countries, particularly in Latin America and Asia. Africa is increasingly using
pesticides on export crops.
Many developing countries have reported acute poisoning because highly toxic
pesticide formulations cannot be handled safely, FAO said. Protective clothing
is often too expensive and, in many cases, cannot be used due to the climate in
these countries. In order to reduce the risks caused by pesticides, FAO assists
developing countries in reducing pesticide use through Integrated Pest
Management.
Studies on the application of organophosphates have demonstrated, for
example, that during normal spraying, farmers are exposed to contamination by
absorption of residues on clothing through the skin. In China alone, 27
provinces in 1995 reported a total of 48,377 poisoning cases, including 3,204
fatalities. More than 7,500 of these cases were mostly attributed to normal
agricultural use of parathion and methamidophos. Poisoning from parathion occurs
even in industrialized countries despite stringent protection.
"The new Convention promises to create a first line of defense against
chemicals risks by empowering governments with the information and procedures
they need to monitor and control cross-border trade", said Mr. Klaus
Toepfer, UNEP's Executive Director. "But because trade is just one avenue
for the spread of highly dangerous substances, we must build on this success
through further agreements to prevent dangerous chemicals like persistent
organic pollutants (POPs) from being released into the environment where they
pose a threat to people and to wildlife," he said.
"The legally binding PIC procedure will help protect farmers in
developing countries from exposure to highly toxic pesticides. Nevertheless, at
national level further measures are required to use pesticides safely and in a
rational manner. The challenge for world agriculture is to produce more food
with less pesticides, in a sustainable way," said Abdoulaye Sawadogo, FAO
Assistant Director-General.
A diplomatic conference will be held later this year in Rotterdam, the
Netherlands, attended by Ministers and Government Representatives to adopt and
sign the new Convention. The meeting in Brussels will be held at the building of
the European Parliament; it is being financed by the European Commission.

official record.
Ninety-five countries agree on the new international
convention on dangerous chemicals and pesticides
BRUSSELS/NAIROBI, 16 March 1998
After two years of negotiations 95 countries unanimously agreed on a legally
binding Convention on international trade and hazardous chemicals and
pesticides, the UN Environment Programme (UNEP) and the Food and Agriculture
Organization (FAO) announced today. Through this treaty governments honoured
their commitment made at the 1992 Rio Earth Summit to negotiate a convention to
curb the trade in certain hazardous chemicals and pesticides.
"The aim of the Convention is to enable importing countries to decide
what chemicals they want to receive and to keep out the ones they cannot manage
safely," said Maria de Azevedo Rodrigues, Chairperson of the Conference.
"It is expected that trade can be better controlled and that the risks of
these dangerous chemicals can be reduced to benefit people and the environment.
Countries also are expected to put national legislation into force. Until the
industry can substitute hazardous chemicals with safer products, especially
those exported to developing countries, a damage control system - as provided by
the Convention - is needed."
Each year large numbers of people are harmed or killed by toxic chemicals and
pesticides. Many of these substances have caused devastating environmental
problems.
In the Preamble of the Convention the countries recognise that "trade
and environmental policies should be mutually supportive" to achieve
sustainable development. The treaty aims at protecting "human health,
including the health of consumers and workers, and the environment."
The Convention addresses the problem that chemicals and pesticides banned or
severely restricted in industrialised countries are still exported to other
countries, very often to the developing world.
The Convention requires that harmful pesticides and chemicals that have been
banned or severely restricted in at least two countries shall not be exported
unless explicitly agreed by the importing country (this is called Prior Informed
Consent Procedure, PIC). The treaty is not a worldwide ban on these chemicals.
The Convention already covers 22 pesticides and five industrial chemicals(*)
that have been banned or severely restricted in a number of countries. More
hazardous chemicals can be added to the PIC list. Developing countries can also
propose the addition of severely hazardous pesticides formulations to this list
if they have the potential to damage human health and the environment under
their normal conditions of use.
The Convention will replace the present voluntary PIC procedure. Based on the
experience of the voluntary PIC, FAO and UNEP estimate that probably more than
50 substances could enter the PIC list in future, subject to the decision of the
Conference of Parties.
Under the new treaty, exporting countries will also be legally bound to
inform importing countries about exports of chemicals banned or severely
restricted in the exporting country. This export notification shall be provided
prior to the first export and be repeated for the first export every year.
Countries that will ratify the treaty will be obliged to enforce the
agreement at national level and to create enforcement mechanisms that will
control commercial exports and exporters. Disputes between states regarding the
implementation of the Convention will be settled either by arbitration or by the
International Court of Justice.
In developing countries and countries in transition "technical
assistance for the development of the infrastructure and the capacity necessary
to manage chemicals" shall be promoted.
The treaty enters into force upon ratification by 50 countries. A diplomatic
conference will be held in Rotterdam, the Netherlands, in September to
officially adopt and sign the new Convention.
According to UNEP, the Convention will help solve several of the major human
health and environmental problems. There are large stockpiles of unwanted and
obsolete pesticides and other chemicals in virtually every developing country.
Each year, thousands of people are poisoned by severely hazardous pesticide
formulations. And there are a number of highly toxic chemicals that persist in
the environment, accumulate in wildlife and people, persist for long periods of
time, and when environmentally released are spread all over the world. These
persistent organic pollutants (POPs) are a major problem. The Convention will
help to manage these serious problems, UNEP said.
FAO warned that many pesticides that have been banned or whose use has been
severely restricted in Europe and North America are still marketed and used in
developing countries. Also, many old, often highly toxic, organophosphorus
pesticide formulations continue to be used there because of their low price.
Often, small farmers simply cannot handle such compounds, FAO warned. Protective
clothing is often too expensive and, in many cases, cannot be used due to the
climate in these countries. The Convention will be powerful tool to limit access
to such compounds. It will help to promote environmentally friendly Integrated
Pest Management in agriculture.
The global market for pesticides continues to grow and is estimated at $30
billion for 1996. Companies based in Western Europe are currently the world's
largest chemical producers. The fastest growing markets are in developing
countries, particularly in Latin America and Asia. Africa is increasingly using
pesticides on export crops.
(*) The PIC list includes the following pesticides:
2,4,5-T, Aldrin, Captafol, Chlordane, Chlordimeform, Chlorbenzilate, DDT,
Dieldrin, Dinoseb, 1,2-dibromoethane (EDB), Fluoroacetamide, HCH, Heptachlor,
Hexachlorobenzene, Lindane, Mercury compounds, certain formulations of
Monocrotophos, Methamidophos, Phosphamidon, Methyl-parathion, Parathion. The
industrial chemicals are: Crocidolite, Polybrominated Biphenyls (PBB),
Polychlorinated Biphenyls (PCB), Polychlorinated Terphenyls (PCT), Tris (2,3
dibromopropyl) phosphate.
