2Times Beach, Missouri- IntroductionMost discoveries have been made as a result of either research, luck, or deadly incidentsMost people are not aware of effects of toxic chemicals until something goes wrong, sometimes leading to deathOnly in these cases do people open their eyes and government agencies get involved
3Times Beach, Missouri- History of Times BeachTimes Beach is located along the Meramec River in MissouriTown founded in 1925 during promotion by the St. Louis Star-Times newspaperFirst used as summer resort with various luxury homesAfter great depression became home to low-income citizens and homesTown did not have enough money to pave its dirt roads (23 miles total) and lead to dust problems
4Times Beach, Missouri- Deadly Incidents - Russell BlissTown hired local waste hauler named Russell Bliss to oil its dirt roads once a week from 1972 to 1976Bliss had effectively used this method to control dust in stablesHigh costs of oil in early 70s forced Bliss to look for cheaper alternates, such as waste oilBliss contracted with Northeastern Pharmaceutical and Chemical Company (NEPACCO) to dispose of its waste oil and began using it to spray Times Beach’s roads and local stablesBliss was unaware the waste oil contained hexachlorophene used in producing Agent Orange, which contained high levels of dioxin
5Times Beach, Missouri- Deadly Incidents - Russell BlissLocal horse stable reports the death of 62 horses, with numerous more being reported in the years following.Bliss assured citizens he was only spraying engine oilCity finally decides to contact the Center for Disease Control and Prevention in 1979 which began an investigation
6Times Beach, Missouri- Toxic Chemical TestingEmployee of NEPACCO confessed to using dioxin in its chemicalsEPA immediately begins testing streets of Times Beach and finds high levels of dioxin in soilDioxin levels were about a hundred times greater then what is considered to be safe
7Times Beach, Missouri- Toxic Chemical TestingVarious environmental companies found various chemicals in the surrounding areas of Times Beach such as:120PPM of toluene430PPM of xylene170PPM of ethyl benzeneFood and Drug Administration found dioxin in fix along Meramec River and Romaine Creek, near Times Beach
8Times Beach, Missouri- Town EvacuationCitizens of Times Beach began reporting numerous miscarriages, diseases and various animal deaths all believed to be associated with DioxinDuring the Christmas of 1982, the town received notice to evacuate and relocate all citizensAnother fifty surrounding smaller towns ordered to evacuate as a result of dioxin spread caused by floodsIncident was the largest exposure to dioxin in US history.
9Times Beach, Missouri- The Chemical DioxinDioxin is one of the most toxic substances known to manEPA has strict laws regulating tolerable daily, monthly and annual amounts of human and animal consumptionMost common way dioxin enters general population is thru ingestion of contaminated fish, meats and dairy products, making dioxin vehicle-borneMost common sources of exposure to dioxin are:Coal fired utilitiesMetal smelting industriesDiesel trucksLand application of sewage sludgeBurning treated wood
10Times Beach, Missouri Dioxins in every day type environments - The Chemical DioxinDioxins in every day type environmentsSmoke from cigarettes caused by the chlorine-bleached cigarette papersVarious products containing plastics, resins, or bleaches such as food packaging productsAlthough these products contain only small amounts of dioxins, no major health risks can occur. However, accumulation of exposure over time could result in health risks.
11Times Beach, Missouri - The Chemical Dioxin - Effects of Dioxin Dioxins and similar compounds in the dioxin family, when ingested, accumulate in fatty tissues.Even small amounts can reach high levels and become dangerous over timeOne major result of exposure to dioxin is chloracneSever form of acneCommonly accompanied by sever disfiguration, joint pain, fatigue, headaches, and chronic weaknessChloracne could remain in your body for up to thirty yearsExposure to dioxins could also lead toDevelopmental abnormalities in children’s teethCancerCentral and peripheral nervous system pathologyThyroid disordersBirth defectsDiabetesChronic obstructive pulmonary diseases
12Times Beach, Missouri- ConclusionAfter the evacuation of Times Beach, it took the government and environmental agencies fifteen years to fully decontaminate the soil with the help of incineratorsThe area of Times Beach has now been returned to the state of Missouri and converted into park areasIncidents in Times Beach provided citizens and government agencies reasons to implement laws concerning safety practices involving chemical manufacturing and waste disposal of chemical productsLong term effects of dioxin in humans and animals is still not fully understood.
