Persistent Organic Pollutants (POPs) are chlorine-based chemicals that slowly poison humans and other animals. Most POPs are either pesticides or byproducts of industrial processes.

The term POPs is short for persistent organic pollutants. POPs are long-lived chemicals that build up in the food chain and slowly poison animals and humans. POPs travel thousands of miles and enter the soil, oceans, rivers, plants, and animals far from where they are produced or used. Indigenous peoples who maintain a land-based culture can be heavily exposed to POPs from their diet. In this way, POPs threaten our culture and our future. The most well-known examples of POPs are PCBs (transformer fluids), DDT (a pesticide) and dioxin, an unwanted byproduct of manufacturing and one of the most toxic man-made substances known. Historical tribal hunting and fishing rights are undermined by POPs contamination. What is the value of a right to fish if the fish are contaminated? Dioxin, PCBs, DDT and nine other chemicals are considered to be "a serious threat to human health" throughout the world by the United Nations. In fact, governments of the world are negotiating a treaty to remove them from the environment. It is critical that this U.N. treaty recognize the serious impacts POPs have on the future of Indigenous Peoples.


Where are POPs Found?

Bob Edwards/Greenpeace 1991

POPs are found in common places. Electrical transformers contain PCBs, Dioxins, furans and other POPs are created during the manufacture of paper and vinyl plastic, which is used to make children's toys, clothing, IV bags and tubing, flooring, pipes, and siding. When vinyl is incinerated or burned in a backyard trash fire, dioxin is formed again. Dioxins are also formed during the manufacture of magnesium and other metals. The POPs pesticides are no longer legally used in North America, but they are used in other countries. Since POPs do not easily degrade and can travel thousands of miles, they can still be found in soil, lakes, rivers, fish, animals, and people long after they are used.

Indigenous Peoples have special cultural and spiritual relationships to traditional foods that create increased consumption patterns compared to non-Indigenous populations. Unfortunately, the main way POPs enter our bodies is through food. POPs have been found in eagles, cormorants, ducks, geese, caribou, reindeer, raccoons, rabbits, quail, deer, moose, bison, turtles, crocodiles, sheep, cows, polar bears, seals, whales, and fish. POPs accumulate in fat and their concentration increases at each step of the food chain. For example, PCBs have been found to accumulate in the livers of sheep. In addition, dieldrin, a pesticide, accumulates in the wool of sheep that eat from contaminated land. Advisories prohibiting or discouraging the consumption of traditional foods affect Indigenous Peoples' right to practice our cultural and spiritual ways. Store-bought food does not solve the contamination problem, since it may also be contaminated.

In many areas of our Indigenous territories, our communities are being told not to eat the contaminated fish and animals. Advisories are being posted everywhere. According to a report by Health Canada, "Great Lakes residents who consume larger amounts of certain species of contaminated fish and wildlife than the general population are at an increased risk of exposure to toxic pollutants." The report names affected subpopulations that include anglers, their families, and Indigenous Peoples.

To Indigenous Peoples, fishing and hunting are not sport or recreation, but part of a spiritual, cultural, social and economic lifestyle that has sustained us from time immemorial. In some areas, fishing and hunting rights are treaty rights. When we no longer can eat fish and wild meat, high protein food is often replaced with junk food like potato chips and soft drinks. In addition, the active social part of harvesting of traditional foods is replaced by a less active lifestyle. The junk food diet is less healthy and has contributed to problems with obesity, high blood pressure and chronic diseases like diabetes. Cutting off traditional food supplies from Indigenous Peoples could be a form of cultural genocide.


Children Are Affected Most

Children are more vulnerable than adults to many kinds of pollution, and POPs are no exception. Toxic exposures during fetal development, infant life, and childhood can have lifelong effects including increased susceptibility to cancer, and damage to the immune and reproductive systems. These health effects may not be apparent until much later in life, making them difficult to link to early-life exposures. For example, a study of children whose mothers ate PCB-contaminated fish from the Great Lakes during pregnancy showed that they had lower intelligence and problems with reading comprehension. These damaging effects were still observed when the children were 11 years old. After birth, POPs can also enter children during breast feeding. Many POPs have been detected at significant levels in the breast milk of Mohawk and Inuit women as well as women from many countries worldwide. The average breast-fed baby in North America grossly exceeds the World Health Organization "acceptable" daily intake of dioxin.

We have a responsibility to our future generations to leave them the Earth as it was left to us. By threatening the health and survival of our children, POPs threaten our future generations.

One example: when POPs from an industrial facility contaminate a nearby body of water, the fish who live there are contaminated also. (POPs build up in animal fat.) Many of these fish are eaten by a larger fish, who is eaten by a human. That human has unintentionally ingested the POPs that have built up at each step in the chain.

The Warning From Animals

Indigenous Peoples have always warned about the dangers of chemicals to the animal, fish and bird nations. In recent years, scientists agree that POPs are the main cause of damage to several types of animals and birds. The continued local extinction of the Lake Ontario bald eagle results from exposure to PCBs and other POPs. The beluga whales of the St. Lawrence estuary and the Alaskan Arctic are highly contaminated by a range of POPs and suffer from a high incidence of tumors and reproductive problems. Reproductive problems, deformities, and behavioral abnormalities in several species of mammals, birds, fish and reptiles in the Great Lakes basin have also been linked to POPs.

Almost everything we eat, drink, or inhale is broken down by our bodies and then expelled through the process of waste elimination. But POPs are different. The poisonous chemicals are stored in fat and build up in our bodies, like water in a stopped-up sink. As we age and are continually exposed to POPs, their concentration becomes higher, and their potential effects on our health become more serious.


A Serious Health Threat to Humans

The pollution of the human body by POPs has occurred together with the appearance of several alarming trends in human health over the past few decades. There has been a precipitous rise in breast cancer, many studies showing dramatic drops in sperm counts and increases in other disorders of the reproductive organs. Numerous studies confirm the toxicity of different POPs to humans. In addition, scientists recognize that POPs can cause these health problems in animals that are commonly used to predict risk to humans.

The U.S. Environmental Protection Agency estimates that exposure to dioxin in the U.S. population is near the levels at which damage to health is known to occur from studies of animals and humans. These health effects include growth and immune system problems, reduced sperm counts and menstrual disorders such as endometriosis. Dioxin is also internationally recognized as a known human carcinogen.

Finally, PCBs and dioxin are suspected to contribute to learning disabilities. According to the World Health Organization, "subtle effects may already occur in the general population in developed countries at current background levels." For Indigenous Peoples, the implications are even more serious since we are more highly exposed to these chemicals.


Earth A Global Treaty Against POPs

Negotiating a Safer Future
The decision to start global intergovernmental negotiations on a legally binding POPs agreement was taken by the Governing Council of the United Nations Environmental Program in February, 1997, and endorsed by the World Heath Organization in May, 1997. The treaty negotiations take place in a series of Intergovernmental Negotiating Committee (INC) meetings that the Governing Council of the U.N. plans to conclude by 2000.

What Chemicals Are Covered?
The POPs chemicals currently included in the U.N. treaty negotiation are: PCBs, dioxins, furans, hexachlorobenzene and POPs pesticides, which include DDT, chlordane, heptachlor toxaphene, aldrin, dieldrin, endrin, and mirex. The U.N. treaty will agree on a way to add other chemicals to this list.
