It was used as an insecticide on crops and livestock (to control ticks, mites, etc.). It was easy and cheap to make, and so it became the most produced organochlorine.
  3. Toxaphene. Regulatory process names 6 Translated names 39 CAS names 1 IUPAC names 2 Other identifiers 17 . POP - Recognised Persistent Organic Pollutant (POP): comes from an entry in the Annex I, II or III to the POPs Regulation and/or an entry in the Annex A, B or C to the Stockholm Convention. Potentially a Persistent Organic Pollutant.
  4. Toxaphene was the most widely used pesticide in the US in 1975. Up to 50% of a toxaphene release can persist in the soil for up to 12 years. For humans, the most likely source of toxaphene exposure is food. While the toxicity to humans of direct exposure is not high, toxaphene has been listed as a possible human carcinogen due to its effects on.

This insecticide is used on cotton, cereal grains, fruits, nuts, and vegetables. It has also been used to control ticks and mites in livestock. Toxaphene was the most widely used pesticide in the US in 1975. Up to 50% of a toxaphene release can persist in the soil for up to 12 years. For humans, the most likely source of toxaphene exposure is food Toxaphene is highly insoluble in water, and has a half-life in soil of up to 12 years. It has been shown to bioconcentrate in aquatic organisms and is known to undergo atmospheric transport. The half-life of toxaphene in soil ranges from 100 days up to 12 years, depending on the soil type and climate. This persistence

The 12 initial POPs under the Stockholm Convention: Initially, twelve POPs have been recognized as causing adverse effects on humans and the ecosystem and these can be placed in 3 categories: Pesticides: aldrin, chlordane, DDT, dieldrin, endrin, heptachlor, hexachlorobenzene, mirex, toxaphene Polluants organiques persistants (POP) LES FAITS NLes POP constituent une menace grave pour la santé humaine et l'environnement. NLe FEM a alloué 341 millions de dollars à des projets visant à réduire l'exposition de l'homme et de l'environnement aux POP, ce qui lui a permis de mobiliser 474 millions de dollars de cofinancemen In North America most POP modeling has focused on regional sources to the Great Lakes. For example, findings from Ma et al. (2005a,b) indicate episodic transport of toxaphene from the southeastern United States to the Great Lakes Heptachlor is an organochlorine compound that was used as an insecticide.Usually sold as a white or tan powder, heptachlor is one of the cyclodiene insecticides. In 1962, Rachel Carson's Silent Spring questioned the safety of heptachlor and other chlorinated insecticides. Due to its highly stable structure, heptachlor can persist in the environment for decades zene,mirex,and toxaphene.POP chemicals targeted for inter-national phase out also include industrial chemicals and byproducts of certain manufacturing processes and waste incineration such as polychlorinated biphenyls (PCBs), dioxins,and furans.

Both toxaphene and chlordane are found in the waters and sediments of the estuary, but if they have no history of use in or around the St. Lawrence basin, where did they. Since 1990, emissions of persistent organic pollutants (POPs) decreased in the EEA-33 countries, e.g. hexachlorobenzene (HCB) decreased by 95 %, polychlorinated biphenyls (PCBs) by 75 %, dioxins and furans by around 70 % and polycyclic aromatic hydrocarbons (PAHs) by 83 %. The majority of countries report that POP emissions fell during the period 1990 to 2017. In 2017, the most significant.

In addition to dioxins and furans, the POP group includes many organochlorine insecticides such as dieldrin, DDT, toxaphene, chlordane, hexachlorobenzene, aldrin, endrin, heptachlor, toxaphene, mirex and several. Stockholm Convention is a global treaty that was adopted by the Conference of Plenipotentiaries in 2001 and came into force on 17th May 2004. It was introduced to protect human health from harmful POPs suspended in the air for a long period of time. The convention aims to reduce or eliminate the use of POPs through the active measures of the.

''It is too little, too late,'' Mr. Butler said, noting the use of toxaphene has declined from 100 million pounds a year in the 1970's to 16 million pounds this year It is a very stable POP with a half-life of up to 10 years. Toxaphene is an insecticide that was widely used in the United States in the 1970s to protect cereal grains, cotton crops, and vegetables. Toxaphene has a half-life of 12 years. Aquatic life is especially vulnerable to toxaphene toxicity

This section contains detailed chemical descriptions of various Persistent Organic Pollutants adapted from Persistent Organic Pollutants: Information on POPs, their alternatives and alternative approaches (United Nations Environmental Programme (UNEP) 1995). For each chemical, an overview is given, and the toxicity to. The 12 targeted POPs include eight pesticides (aldrin, chlordane, DDT, dieldrin, endrin, heptachlor, mirex, and toxaphene), two types of industrial chemicals (polychlorinated biphenyls or PCBs and hexachlorobenzene), and two chemical families of unintended by-products of the manufacture, use, and/or combustion of chlorine and chlorine.

Industrial Chemicals. Let us see the two industrial chemicals listed as the most dangerous POPs

The substances covered by the treaty are eight pesticides (aldrin, chlordane, DDT, dieldrin, endrin, heptachlor, mirex, and toxaphene), two industrial chemicals (hexachlorobenzene (HCB) and polychlorinated biphenyls (PCBs)), and two POP by-products (dioxins and furans). 1, 2 The first 10 compounds, except DDT, are included in Annex A.
