The Circle of Poison (COP) refers to the export of domestically banned pesticides for use on foods elsewhere, some of which returns by way of import. [3] [4] [5] The "circle" is complete when the toxic chemicals that were exported are then used to grow fruit, meat, and produce that are imported and available for domestic consumption. [6] This circle was first identified relative to the United States but the relationship also exists between other nations of the Global North and South.
In the book, Circle of Poison: Pesticides and People in a Hungry World, David Weir and Mark Schapiro of the Oakland-based Center for Investigative Reporting present an investigative study of how certain dangerous chemicals, which are banned in the U.S., still enter back into the United States and the American diet through food imports. Many restricted chemicals, especially pesticides, are produced in the U.S. and exported to the global south. [7] The banned chemicals are then used on 'cash crops', which are subsequently exported to the U.S. and other industrialized countries for high profit. [8]
The investigative study done by Wier and Schapiro showed that the highly potent and dangerous chemicals used in domestic agriculture led to a public clamor for strict regulations, and that pesticides contribute to the expansion of an export-oriented agriculture at the expense of food production for local needs. Even where they are applied to food crops, pesticides are often linked to the Green Revolution, which can mean more hunger even while it raises production. Pesticides, they argue, are no solution to hunger-they bypass the needs of the poor who 'have neither money to buy food nor the land to grow it on'. Moreover, they claim because agrochemical companies are profit driven, they have tailored the regulations to permit unrestricted export of dangerous chemicals. [9] Wier and Schapiro argue that this loophole has been a disaster. [10]
In April 1991, the "Circle of Poison prevention Act" was introduced by Senator Patrick Leahy (D-VT) in the U.S. Senate and by Representatives Mike Synar (D-OK) and Leon Panetta (D-CA) in the House. [11] This bill would have placed strict controls on exports of hazardous chemicals. [12] Similar legislation passed both houses of Congress but died in conference committee. [13]
In brief, the "Circle of Poison Prevention Act" would have: [14]
The United States Environmental Protection Agency (EPA) has the authority to regulate the sale and use of pesticides in the United States; before a pesticide can be sold, it must be licensed or registered by the EPA. [15] While registration does not constitute "approval" by the EPA, it means that the agency has determined that a pesticide will not cause 'unreasonable adverse effects' on humans or the environment. [16] The EPA may cancel or suspend the registration of a pesticide, if further evidence indicates that its use poses unreasonable hazard. Or it may restrict the uses for which it may be sold to very specific crops and application practices. [17]
The EPA does not have the authority to prohibit the export of canceled or suspended pesticides; nor may it forbid the export of restricted use pesticides that may be equally hazardous in the hands of untrained applicators or new compounds, which have never been granted registration. [18] Consequently, millions of pounds of pesticides, which have been determined to be unsafe for use in the U.S., are shipped to foreign ports. [19]
The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and the Federal Food, Drug, and Cosmetic Act, are the two major laws responsible for pesticide control in the U.S. Department of Agriculture, and are also responsible for the safety of foods containing pesticide residues to the Department of Health, Education, and Welfare. The Secretary has delegated this responsibility to the Food and Drug Administration.
Pesticides are substances that are used to control pests. They include herbicides, insecticides, nematicides, fungicides, and many others. The most common of these are herbicides, which account for approximately 50% of all pesticide use globally. Most pesticides are used as plant protection products, which in general protect plants from weeds, fungi, or insects. In general, a pesticide is a chemical or biological agent that deters, incapacitates, kills, or otherwise discourages pests. Target pests can include insects, plant pathogens, weeds, molluscs, birds, mammals, fish, nematodes (roundworms), and microbes that destroy property, cause nuisance, or spread disease, or are disease vectors. Along with these benefits, pesticides also have drawbacks, such as potential toxicity to humans and other species.
Daminozide, also known as aminozide, Alar, Kylar, SADH, B-995, B-nine, and DMASA, is a plant growth regulator. It was produced in the U.S. by the Uniroyal Chemical Company, Inc,, which registered daminozide for use on fruits intended for human consumption in 1963. In addition to apples and ornamental plants, they also registered it for use on cherries, peaches, pears, Concord grapes, tomato transplants, and peanut vines. Alar was first approved for use in the U.S. in 1963. It was primarily used on apples until 1989, when the manufacturer voluntarily withdrew it after the U.S. Environmental Protection Agency proposed banning it based on concerns about cancer risks to consumers.
Bromomethane, commonly known as methyl bromide, is an organobromine compound with formula CH3Br. This colorless, odorless, nonflammable gas is produced both industrially and biologically. It is a recognized ozone-depleting chemical. It was used extensively as a pesticide until being phased out by most countries in the early 2000s. From the chemistry perspective, it is one of the halomethanes.
Lindane, also known as gamma-hexachlorocyclohexane (γ-HCH), gammaxene, Gammallin and benzene hexachloride (BHC), is an organochlorine chemical and an isomer of hexachlorocyclohexane that has been used both as an agricultural insecticide and as a pharmaceutical treatment for lice and scabies.
Carbofuran is a carbamate pesticide, widely used around the world to control insects on a wide variety of field crops, including potatoes, corn and soybeans. It is a systemic insecticide, which means that the plant absorbs it through the roots, and from there the plant distributes it throughout its organs where insecticidal concentrations are attained. Carbofuran also has contact activity against pests. It is one of the most toxic pesticides still in use.
Chlorpyrifos (CPS), also known as chlorpyrifos ethyl, is an organophosphate pesticide that has been used on crops, animals, and buildings, and in other settings, to kill several pests, including insects and worms. It acts on the nervous systems of insects by inhibiting the acetylcholinesterase enzyme. Chlorpyrifos was patented in 1966 by Dow Chemical Company.
The Toxic Substances Control Act (TSCA) is a United States law, passed by the 94th United States Congress in 1976 and administered by the United States Environmental Protection Agency (EPA), that regulates chemicals not regulated by other U.S. federal statutes, including chemicals already in commerce and the introduction of new chemicals. When the TSCA was put into place, all existing chemicals were considered to be safe for use and subsequently grandfathered in. Its three main objectives are to assess and regulate new commercial chemicals before they enter the market, to regulate chemicals already existing in 1976 that posed an "unreasonable risk of injury to health or the environment", as for example PCBs, lead, mercury and radon, and to regulate these chemicals' distribution and use.
The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) is a United States federal law that set up the basic U.S. system of pesticide regulation to protect applicators, consumers, and the environment. It is administered and regulated by the United States Environmental Protection Agency (EPA) and the appropriate environmental agencies of the respective states. FIFRA has undergone several important amendments since its inception. A significant revision in 1972 by the Federal Environmental Pesticide Control Act (FEPCA) and several others have expanded EPA's present authority to oversee the sales and use of pesticides with emphasis on the preservation of human health and protection of the environment by "(1) strengthening the registration process by shifting the burden of proof to the chemical manufacturer, (2) enforcing compliance against banned and unregistered products, and (3) promulgating the regulatory framework missing from the original law".
Aldicarb is a carbamate insecticide which is the active substance in the pesticide Temik. It is effective against thrips, aphids, spider mites, lygus, fleahoppers, and leafminers, but is primarily used as a nematicide. Aldicarb is a cholinesterase inhibitor which prevents the breakdown of acetylcholine in the synapse. Aldicarb is considered "extremely hazardous" by the EPA and World Health Organization and has been banned in more than 100 countries. In case of severe poisoning, the victim dies of respiratory failure.
Endosulfan is an off-patent organochlorine insecticide and acaricide that is being phased out globally. It became a highly controversial agrichemical due to its acute toxicity, potential for bioaccumulation, and role as an endocrine disruptor. Because of its threats to human health and the environment, a global ban on the manufacture and use of endosulfan was negotiated under the Stockholm Convention in April 2011. The ban took effect in mid-2012, with certain uses exempted for five additional years. More than 80 countries, including the European Union, Australia, New Zealand, several West African nations, the United States, Brazil, and Canada had already banned it or announced phase-outs by the time the Stockholm Convention ban was agreed upon. It is still used extensively in India and China despite laws against its use. It is also used in a few other countries. It is produced by the Israeli firm Makhteshim Agan and several manufacturers in India and China. On May 13, 2011, the India Supreme Court ordered a ban on the production and sale of endosulfan in India, pending further notice.
Pesticide residue refers to the pesticides that may remain on or in food, after they are applied to food crops. The maximum allowable levels of these residues in foods are stipulated by regulatory bodies in many countries. Regulations such as pre-harvest intervals also prevent harvest of crop or livestock products if recently treated in order to allow residue concentrations to decrease over time to safe levels before harvest.
The environmental effects of pesticides describe the broad series of consequences of using pesticides. The unintended consequences of pesticides is one of the main drivers of the negative impact of modern industrial agriculture on the environment. Pesticides, because they are toxic chemicals meant to kill pest species, can affect non-target species, such as plants, animals and humans. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, because they are sprayed or spread across entire agricultural fields. Other agrochemicals, such as fertilizers, can also have negative effects on the environment.
Organic food, ecological food, or biological food are foods and drinks produced by methods complying with the standards of organic farming. Standards vary worldwide, but organic farming features practices that cycle resources, promote ecological balance, and conserve biodiversity. Organizations regulating organic products may restrict the use of certain pesticides and fertilizers in the farming methods used to produce such products. Organic foods are typically not processed using irradiation, industrial solvents, or synthetic food additives.
Pesticides in the United States are used predominantly by the agricultural sector, but approximately a quarter of them are used in houses, yards, parks, golf courses, and swimming pools.
There is a high use of pesticides in New Zealand due predominantly to the large agricultural industry.
The California Department of Pesticide Regulation, also known as DPR or CDPR, is one of six boards and departments of the California Environmental Protection Agency (Cal/EPA).
Solid waste policy in the United States is aimed at developing and implementing proper mechanisms to effectively manage solid waste. For solid waste policy to be effective, inputs should come from stakeholders, including citizens, businesses, community-based organizations, non-governmental organizations, government agencies, universities, and other research organizations. These inputs form the basis of policy frameworks that influence solid waste management decisions. In the United States, the Environmental Protection Agency (EPA) regulates household, industrial, manufacturing, and commercial solid and hazardous wastes under the 1976 Resource Conservation and Recovery Act (RCRA). Effective solid waste management is a cooperative effort involving federal, state, regional, and local entities. Thus, the RCRA's Solid Waste program section D encourages the environmental departments of each state to develop comprehensive plans to manage nonhazardous industrial and municipal solid waste.
Pesticide regulation in the United States is primarily a responsibility of the Environmental Protection Agency (EPA). In America, it was not till the 1950s that pesticides were regulated in terms of their safety. The Pesticides Control Amendment (PCA) of 1954 was the first time Congress passed guidance regarding the establishment of safe limits for pesticide residues on food. It authorized the Food and Drug Administration (FDA) to ban pesticides they determined to be unsafe if they were sprayed directly on food. The Food Additives Amendment, which included the Delaney Clause, prohibited the pesticide residues from any carcinogenic pesticides in processed food. In 1959, pesticides were required to be registered.
Oxamyl is a chemical used as a pesticide that comes in two forms: granulated and liquid. The granulated form has been banned in the United States. It is commonly sold under the trade name Vydate.
Dietary exposure assessments in the United States involve the evaluation of dietary consumption and chemical residue data while taking into consideration additional factors that may affect a specified population of interest or sensitive population. The process of conducting a dietary exposure assessment involves the determination of the chemical residues on a particular food or foods and the calculation of the dietary exposure to these chemicals based on consumption data for the specified food or foods. A dietary exposure assessment allows a comparison to a relevant health standard such as the acceptable daily intake(ADI), the acute reference dose.
