Times Beach is a ghost town in St. Louis County, Missouri, St. Louis County, Missouri, United States, southwest of St. Louis, Missouri, St. Louis and east of Eureka, Missouri, Eureka. Once home to more than two thousand people, the town was completely evacuated in early 1983 due to 2,3,7,8-Tetrachlorodibenzodioxin, TCDD (a type of dioxins and dioxin-like compounds, dioxin) contamination, formerly the largest civilian exposure to the compound in the history of the United States. In 1985, the State of Missouri officially disincorporated the city of Times Beach. The site of Times Beach now houses a Route 66 State Park, state park which opened in 1999.

Agent Orange
Agent Orange is a chemical herbicide and defoliant, one of the tactical uses of Rainbow Herbicides. It was used by the U.S. military as part of its herbicidal warfare program, Operation Ranch Hand, during the Vietnam War from 1962 to 1971. The U.S. was strongly influenced by the British who used Agent Orange during the Malayan Emergency. It is a mixture of equal parts of two herbicides, 2,4,5-Trichlorophenoxyacetic acid, 2,4,5-T and 2,4-Dichlorophenoxyacetic acid, 2,4-D. Agent Orange was produced in the United States beginning in the late 1940s and was used in industrial agriculture, and was also sprayed along railroads and power lines to control undergrowth in forests. During the Vietnam War, the U.S. military procured over , consisting of a fifty-fifty mixture of 2,4-D and dioxin-contaminated 2,4,5-T.

NEPACCO
NEPACCO, or the "North Eastern Pharmaceuticals and Chemicals Co" was a pharmaceutical and chemical company founded in 1966 in Stamford, Connecticut, best known for its role in the Times Beach, Missouri, Times Beach Chemical accident, Hazmat Incident. NEPACCO's main product was hexachlorophene, which it began producing after leasing a Verona, Missouri based chemical production facility from Hoffman-Taff in 1969. As a byproduct of this process, 2,3,7,8-Tetrachlorodibenzodioxin, dioxin, most well known for its use in Agent Orange during the Vietnam War, was created. Although the dioxin was initially held on site, it was eventually improperly disposed of in a trench in the facility, and by a local waste handler, Russell Bliss. Following the ban of Hexachlorophene in 1972, NEPACCO halted production on the site. By 1974, the company had liquidated all its assets, and was shut down by the Delaware Secretary of state, Secretary of State in 1976. Edwin Michaels and John W. Lee, the Presid ...

Syntex Agribusiness
Laboratorios Syntex SA (later Syntex Laboratories, Inc.) was a pharmaceutical company formed in Mexico City in January 1944 by Russell Marker, Emeric Somlo, and Federico Lehmann to manufacture therapeutic steroids from the Mexican yams called ''cabeza de negro'' (''Dioscorea mexicana'') and ''Barbasco'' (''Dioscorea composita''). The demand for barbasco by Syntex initiated the Mexican barbasco trade. As the American Chemistry Society later explained: “In early 1944, the new Mexican company was chartered and named Syntex, S.A. (‘Synthesis and Mexico’). Russell Marker, shortly thereafter, left Syntex on account of his ruthless cofounder. Luis E. Miramontes, George Rosenkranz and Carl Djerassi's successful synthesis of norethisterone (also known as norethindrone) — which was later proven to be an effective pregnancy inhibitor — led to an infusion of capital into Syntex and the Mexican steroid pharmaceutical industry. George Rosenkranz and Carl Djerassi went on to synthesi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hexachlorophene
Hexachlorophene, also known as Nabac, is an organochlorine compound that was once widely used as a disinfectant. The compound occurs as a white odorless solid, although commercial samples can be off-white and possess a slightly phenolic odor. It is insoluble in water but dissolves in acetone, ethanol, diethyl ether, and chloroform. In medicine, hexachlorophene is useful as a topical anti-infective and anti-bacterial agent. It is also used in agriculture as a soil fungicide, plant bactericide, and acaricide. Production Hexachlorophene is produced by alkylation of 2,4,5- trichlorophenol with formaldehyde. Related antiseptics are prepared similarly, e.g., bromochlorophene and dichlorophene. Safety The LD50 (oral, rat) is 59 mg/kg, indicating that the compound is relatively toxic. It is not mutagenic nor teratogenic according to Ullmann's Encyclopedia, but "embryotoxic and produces some teratogenic effects" according to the International Agency for Research on Cancer. 2,3 ...

Animal Feed
Animal feed is food given to domestic animals, especially livestock, in the course of animal husbandry. There are two basic types: fodder and forage. Used alone, the word ''feed'' more often refers to fodder. Animal feed is an important input to animal agriculture, and is frequently the main cost of the raising or keeping of animals. Farms typically try to reduce cost for this food, by growing their own, grazing animals, or supplementing expensive feeds with substitutes, such as food waste like spent grain from beer brewing. Animal wellbeing is highly dependent on feed that reflects a well balanced nutrition. Some modern agricultural practices, such as fattening cows on grains or in feed lots, have detrimental effects on the environment and animals. For example, increased corn or other grain in feed for cows, makes their microbiomes more acidic weakening their immune systems and making cows a more likely vector for ''E. coli'', while other feeding practices can improve anima ...
