What
Must Be Done
|
That POPs have
become widespread environmental contaminants is abundantly clear from the
presence of many POPs in animal and human tissues in both industrialised
and industrialising countries as well in remote areas such as the Arctic
and deep oceans. Currently, this problem of global POPs contamination is
set to continue because the majority of POPs from man's activities are still
being released into the environment.
| Only a few have been banned and even this is in limited parts of the world. Furthermore, the decrease in environmental levels of a few banned POPs, such as some of the chlorinated pesticides, gives no room for optimism or complacency. Levels of banned POPs are still high enough to be of concern, and moreover, levels of other POPs which are still being widely produced, such as dioxins and the brominated flame retardants, add to the already heavy environmental burden of POPs. |
Many POPs are
passed from a mother's body to the developing young in wildlife and humans
alike. This intergenerational transfer of POPs threatens the health of future
populations. In addition, there may be many other POPs in breast milk, which
have not yet been studied.
| Because
the release of POPs into the environment is continuing, there is a potential
for further severe impacts on the health of wildlife and humans. Continuing
uses of brominated flame-retardants, for instance, could lead to devastating
effects on wildlife similar to those caused by PCBs. Problems may even worsen as the number and quantity of chemicals produced is increasing and most chemicals currently in use have never been tested to assess their potential hazards. |
Given the persistent nature of POPs, there is only one way forward to safeguard future generations. This is to phase out the production and use of all POPs and other hazardous substances and implement clean production technologies. Action must be taken now to address the existing POPs problems, prevent new problems and start on the road to a Toxics Free Future.
To achieve this will require acceptance of much greater responsibility for the chemicals we, as society, produce and use. The bulk of this responsibility must, ultimately, be borne by those who profit from the manufacture and/or marketing of chemicals or the processes that generate them.
In addition,
ongoing and further development of regional and global Conventions, and
the transposition of these commitments into national law, will be necessary
to implement and enforce legislation to phase out POPs and hazardous chemicals.
CLEAN DESTRUCTION TECHNOLOGIES
The following is taken from the report: Technical Criteria for Destruction
of Stockpiled Persistent Organic Pollutants, 1998. Read the full report

Governments of the world are currently negotiating a global, legally binding
instrument to protect human health and the environment from persistent organic
pollutants (POPs). One important way these pollutants enter the general
environment is by escaping from stores, stocks and environmental reservoirs
(including contaminated soils and sediments) of obsolete POPs chemicals
(PCBs, pesticides, etc.) and of POPs-contaminated wastes (dioxins, PCBs,
etc.).
There is now a growing consensus that stocks, stores and environmental reservoirs
of obsolete chemicals and POPs-contaminated wastes must be rapidly identified,
properly collected and properly destroyed in order to stem their continued
migration into the general environment. This, in turn, opens up a debate
on what constitutes proper means for the collection and destruction of these
obsolete chemicals and wastes.
Greenpeace has concluded that to afford adequate protection of both local
and distant populations of humans and wildlife, the technologies used for
destroying stockpiles of persistent organic pollutants (POPs) must meet
the following fundamental performance criteria:
1. Destruction efficiencies of effectively 100 percent for the chemicals
of concern. The determination of 100 percent destruction efficiency is necessarily
based on findings of no detectable concentrations of the chemicals of concern
in any and all residues, using the most sensitive analytical techniques
available worldwide. Analyses of the unmodified residues must be carried
out sufficiently frequently to ensure compliance with this criterion during
startups, shutdowns and routine operations.
2. Complete containment of all residues for screening and, if necessary,
reprocessing to ensure that no residues contain detectable levels of chemicals
of concern or other harmful constituents, such as newly formed persistent
organic pollutants or other hazardous substances.
3. No uncontrolled releases.
Combustion technologies that have historically been used to attempt the
destruction of POPs stocks and POPs-contaminated materials have failed to
meet these criteria. Indeed, combustion technologies themselves are identified
as major sources from which POPs and other hazardous substances are released
to the environment.
In recent years, several international and national agencies and organizations
have evaluated other destruction technologies, some of which are now in
commercial-scale operation in one or more countries. Like the combustion
technologies, these newer technologies have high resource demands and may
otherwise exact a toll on the environment, the safety and health of workers,
and the general public that renders them unacceptable for continued, long-term
use, as in the disposal of wastes from ongoing domestic and industrial activities.
Some of these newer technologies (for example, gas-phase chemical reduction)
do represent a substantial qualitative improvement over combustion for the
destruction of stores, stocks and environmental reservoirs of obsolete POPs
chemicals and POPs-contaminated wastes. In many cases, these newer technologies,
if properly implemented, represent a better alternative than a decision
to incinerate or to take no action and wait for a better POPs destruction
technology to emerge.
GREENPEACE DEMANDS ...
The production and use of all POPs must be phased out at national, as well as international and, ultimately, at a global level.
This must be
achieved through the substitution of POPs (or the processes which generate
them) with non-hazardous alternatives.
As a matter of urgency, action must be taken to stop production, eliminate all discharges, emissions and losses of those chemicals prioritised for action by regional governments and the UNEP, many of which are POPs.
Presume that all chemicals are hazardous until demonstrated otherwise, i.e. until hazard identification is completed, or in those instances where hazard identification is limited by lack of information, chemicals must be assumed to present hazards of unknown proportions.
Ultimately, measures to eliminate releases of POPs and other hazardous substances to the environment will need to be taken not just on a regional but on a global basis, because chemical contamination of the environment is a global problem and chemicals do not respect national boundaries.
OSPAR countries therefore should not only give highest priority to implement the one generation elimination goal of all hazardous substances in Europe, but also aim at this elimination goal at the global level through the UNEP convention for the elimination of POPs.
This is an
essential first step if the target of cessation of emissions, discharges
and losses of ALL hazardous substances as agreed at ministerial level
in OSPAR countries, is to be achieved within one generation (by 2020) in
the OSPAR countries as well as globally in order to reach a toxic free future.
