Velsicol Chemical Corporation is an American chemical company based in Rosemont, Illinois, that specializes in chemical intermediates for applications such as agrochemicals. It was founded in 1931 by Joseph Regenstein and Julius Hyman.
When, in 1962, the landmark anti-pesticide book Silent Spring was first published, Velsicol was the sole manufacturer of two pesticides – chlordane and heptachlor – featured prominently within it. Subsequently, these pesticides were banned. At the time, Velsicol threatened legal action against Silent Spring's publisher Houghton Mifflin, though ultimately no such action was taken. [1] In 1979, Australian politician and medical researcher John Coulter gave a lecture that mentioned how Velsicol had handled information about the cancer-causing properties of the two pesticides. Velsicol contacted the director of the Institute of Medical and Veterinary Science (now SA Pathology), where Coulter worked, about the lecture. Coulter lost his job in early 1980. In a later court hearing, however, none of the reasons that were given for the dismissal were found to be substantiated. [2] [lower-alpha 1]
For years, Velsicol produced polybrominated biphenyls, DDT, cattle feed additives, and various other chemicals at its Michigan Chemical Corporation plant in St. Louis, Michigan. In 1973, a packaging error at the plant resulted in several thousand pounds of PBBs contaminating cattle feed which was later fed to animals across Michigan. When the error was finally recognized, all the cattle in the state were culled. This error led directly to Gerald Ford's half-hearted approval in 1976 of the Toxic Substances Control Act, which "remains one of the most controversial regulatory bills ever passed". [3] The site of the St. Louis plant is one of the costliest Superfund sites in America. In 2014, the neighborhood around the plant was found to be contaminated with DDT, presumably by Velsicol decades before, prompting the removal and replacement of soil at 96 residential properties. [4]
In 2005, Velsicol was acquired by the private equity firm Arsenal Capital Partners, who, in 2007, re-branded the unit manufacturing benzoic acid, sodium benzoate, and specialty plasticizers as Genovique Specialties Corporation. Arsenal still owns Velsicol. [5] They began selling benzoic acid and sodium benzoate again in 2015 and 2017 respectively. [6]
Endrin is a solid organochlorine pesticide developed by Velsicol with the molecular formula of . The colorless and odorless crystalline solid is dissolved in a liquid for pesticide use against rodents, insects, and birds. The compound is widely regarded as an environmental hazard, showing acute toxicity in humans and severe toxicity in animals, specifically aquatic wildlife as well. [7]
Endrin can be exposed to humans by inhalation, skin absorption, or ingestion. There are many adverse health effects that are associated with Endrin. According to the CDC, several studies have shown that people exposed to high levels of Endrin experience convulsions, jerking of legs and arms, twitching facial muscles, sudden collapse, or even death. Studies have also shown that animals who have eaten and breathed the same high levels of endrin had very similar health effects as humans. [8]
Although there are no long-term effects on human health directly linked to Endrin, its ability to create temporary illness caused the substance to be banned from being used as an insecticide and eventually the production of Endrin altogether within the United States. Because of the potentially harmful adverse effects of Endrin on human health and wildlife, the chemical was officially banned on October 10, 1984. However production of Endrin wasn’t canceled until 1991 in the United States. [1]
United states vs. Velsicol Chemical Corp. The civil court imposed a $30,000 penalty on Velsicol on August 31, 1978, for more than 300 violations of the NPDES permit which restricts the releases of pesticides endrin and more into sewage. [9]
Endrin has minimal effect on soil, however from the Velsicol Chemical Corporation handbook, Endrin is “toxic to fish and wildlife” and it is recommended that Endrin is “kept out of lakes, streams and ponds”. Endrin is meant to be properly handled. The recommendations by Vesicol are “do not contaminate water”. In case fish kills, fish must be collected promptly and disposed of by buna”. [10]
According to InChem,”high toxicity of endrin can cause acute environmental problems when there are uncontrolled discharges during its manufacture, formulation or use.” InChem also recommends that “The manufacture, formulation, agricultural use, and disposal of endrin should be carefully managed to minimize contamination of the environment, particularly surface waters. [11]
Dichlorodiphenyltrichloroethane, commonly known as DDT, is a colorless, tasteless, and almost odorless crystalline chemical compound, an organochloride. Originally developed as an insecticide, it became infamous for its environmental impacts. DDT was first synthesized in 1874 by the Austrian chemist Othmar Zeidler. DDT's insecticidal action was discovered by the Swiss chemist Paul Hermann Müller in 1939. DDT was used in the second half of World War II to limit the spread of the insect-borne diseases malaria and typhus among civilians and troops. Müller was awarded the Nobel Prize in Physiology or Medicine in 1948 "for his discovery of the high efficiency of DDT as a contact poison against several arthropods". The WHO's anti-malaria campaign of the 1950s and 1960s relied heavily on DDT and the results were promising, though there was a resurgence in developing countries afterwards.
Insecticides are pesticides used to kill insects. They include ovicides and larvicides used against insect eggs and larvae, respectively. Acaricides, which kill mites and ticks, are not strictly insecticides, but are usually classified together with insecticides. The major use of Insecticides is agriculture, but they are also used in home and garden, industrial buildings, vector control and control of insect parasites of animals and humans. Insecticides are claimed to be a major factor behind the increase in the 20th-century's agricultural productivity. Nearly all insecticides have the potential to significantly alter ecosystems; many are toxic to humans and/or animals; some become concentrated as they spread along the food chain.
Chlordane, or chlordan, is an organochlorine compound that was used as a pesticide. It is a white solid. In the United States, chlordane was used for termite-treatment of approximately 30 million homes until it was banned in 1988. Chlordane was banned 10 years earlier for food crops like corn and citrus, and on lawns and domestic gardens.
Chlordecone, better known in the United States under the brand name Kepone, is an organochlorine compound and a colourless solid. It is an obsolete insecticide, now prohibited in the western world, but only after many thousands of tonnes had been produced and used. Chlordecone is a known persistent organic pollutant that was banned globally by the Stockholm Convention on Persistent Organic Pollutants in 2009.
The Rocky Mountain Arsenal was a United States chemical weapons manufacturing center located in the Denver Metropolitan Area in Commerce City, Colorado. The site was completed December 1942, operated by the United States Army throughout the later 20th century and was controversial among local residents until its closure in 1992.
Berry's Creek is a tributary of the Hackensack River in the New Jersey Meadowlands in Bergen County, New Jersey. The creek watershed contains a diverse array of wetlands, marshes, and wildlife. The creek runs through a densely populated region and has been subject to extensive industrial pollution during the 19th and 20th centuries. Several companies discharged toxic chemicals into the creek in the 20th century, and these chemicals have remained in the sediment. The creek has the highest concentrations of methyl mercury of any fresh-water sediment in the world. Portions of the creek watershed are Superfund sites and cleanup projects began in the late 20th century.
Persistent organic pollutants (POPs) are organic compounds that are resistant to degradation through chemical, biological, and photolytic processes. They are toxic and adversely affect human health and the environment around the world. Because they can be transported by wind and water, most POPs generated in one country can and do affect people and wildlife far from where they are used and released.
Dieldrin is an organochlorine compound originally produced in 1948 by J. Hyman & Co, Denver, as an insecticide. Dieldrin is closely related to aldrin, which reacts further to form dieldrin. Aldrin is not toxic to insects; it is oxidized in the insect to form dieldrin which is the active compound. Both dieldrin and aldrin are named after the Diels-Alder reaction which is used to form aldrin from a mixture of norbornadiene and hexachlorocyclopentadiene.
Xenoestrogens are a type of xenohormone that imitates estrogen. They can be either synthetic or natural chemical compounds. Synthetic xenoestrogens include some widely used industrial compounds, such as PCBs, BPA, and phthalates, which have estrogenic effects on a living organism even though they differ chemically from the estrogenic substances produced internally by the endocrine system of any organism. Natural xenoestrogens include phytoestrogens which are plant-derived xenoestrogens. Because the primary route of exposure to these compounds is by consumption of phytoestrogenic plants, they are sometimes called "dietary estrogens". Mycoestrogens, estrogenic substances from fungi, are another type of xenoestrogen that are also considered mycotoxins.
Toxaphene was an insecticide used primarily for cotton in the southern United States during the late 1960s and the 1970s. Toxaphene is a mixture of over 670 different chemicals and is produced by reacting chlorine gas with camphene. It can be most commonly found as a yellow to amber waxy solid.
Aldrin is an organochlorine insecticide that was widely used until the 1990s, when it was banned in most countries. Aldrin is a member of the so-called "classic organochlorines" (COC) group of pesticides. COCs enjoyed a very sharp rise in popularity during and after World War II. Other noteworthy examples of COCs include dieldrin and DDT. After research showed that organochlorines can be highly toxic to the ecosystem through bioaccumulation, most were banned from use. Before the ban, it was heavily used as a pesticide to treat seed and soil. Aldrin and related "cyclodiene" pesticides became notorious as persistent organic pollutants.
Endrin is an organochlorine compound with the chemical formula C12H8Cl6O that was first produced in 1950 by Shell and Velsicol Chemical Corporation. It was primarily used as an insecticide, as well as a rodenticide and piscicide. It is a colourless, odorless solid, although commercial samples are often off-white. Endrin was manufactured as an emulsifiable solution known commercially as Endrex. The compound became infamous as a persistent organic pollutant and for this reason it is banned in many countries.
Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste. The most common chemicals involved are petroleum hydrocarbons, polynuclear aromatic hydrocarbons, solvents, pesticides, lead, and other heavy metals. Contamination is correlated with the degree of industrialization and intensity of chemical substance. The concern over soil contamination stems primarily from health risks, from direct contact with the contaminated soil, vapour from the contaminants, or from secondary contamination of water supplies within and underlying the soil. Mapping of contaminated soil sites and the resulting clean ups are time-consuming and expensive tasks, and require expertise in geology, hydrology, chemistry, computer modelling, and GIS in Environmental Contamination, as well as an appreciation of the history of industrial chemistry.
Environmental toxicology is a multidisciplinary field of science concerned with the study of the harmful effects of various chemical, biological and physical agents on living organisms. Ecotoxicology is a subdiscipline of environmental toxicology concerned with studying the harmful effects of toxicants at the population and ecosystem levels.
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.
The Montrose Chemical Corporation of California was a chemical corporation that was the largest producer of the insecticide DDT in the United States from 1947 until it stopped production in 1982. Its improper disposal of chemical waste from DDT production resulted in serious environmental damage to the Pacific Ocean near Los Angeles, and its former main plant in Harbor Gateway South area of Los Angeles near Torrance, California has been designated as a Superfund site by the United States Environmental Protection Agency.
Hexachlorocyclopentadiene (HCCPD), also known as C-56, Graphlox, and HRS 1655, is an organochlorine compound with the formula C5Cl6. It is a precursor to pesticides, flame retardants, and dyes. It is a colourless liquid, although commercial samples appear lemon-yellow liquid sometimes with a bluish vapour. Many of its derivatives proved to be highly controversial, as studies showed them to be persistent organic pollutants. An estimated 270,000 tons were produced until 1976, and smaller amounts continue to be produced today.
Persistent, bioaccumulative and toxic substances (PBTs) are a class of compounds that have high resistance to degradation from abiotic and biotic factors, high mobility in the environment and high toxicity. Because of these factors PBTs have been observed to have a high order of bioaccumulation and biomagnification, very long retention times in various media, and widespread distribution across the globe. Most PBTs in the environment are either created through industry or are unintentional byproducts.
Brook Industrial Park (BIP) is an industrial area occupying 4.5 acres of the Borough of Bound Brook, New Jersey, in the United States of America. It is located on the northern bank of the Raritan River. Industrial, chemical and pesticide operations began in 1971 and eventually lead to the contamination of groundwater and exposure of workers to harmful dioxins. Throughout 1980 to 1988 the United States Environmental Protection Agency (EPA) and the New Jersey Department of Environmental Protection (NJDEP) conducted studies to determine if there were any threats being posed on the workers, community or environment by the BIP companies in their disposal of processed and stored chemicals.
During the 20th century, a large amount of chemical waste was dumped into the Pacific Ocean within the Southern California Bight off the West Coast of the United States. Dumped materials include DDT, WW II munitions, radioactive waste, PCBs, petroleum products, and sulfuric acid.
