System Of A Down: System Of A Down - Toxicity

Product Information

Hydrogen chloride (a severe irritant to the eyes, skin, nasal passages, and lungs). It is likely that the symptoms that residents experienced were from this. At very high concentrations HCl can be fatal but you would know it was present long before it would reach lethal levels. It is very unpleasant to get even a whiff.

Among the many functions of the NFPA is the identification and evaluation of hazardous materials that first responders may encounter in case of a fire or spill. As such, the organization has a database of hundreds of potentially hazardous chemicals along with warnings about the particular hazards of each substance. As stated in the NFPA's disclaimer (1) the information provided is qualitative, not quantitative, and may have data gaps. Nonetheless, it is a useful tool for coping with accidents like the one in Ohio. Here's an example of an NFPA safety diamond. If vinyl chloride is released to soil, it will be subject to rapid volatilization with reported half-lives of 0.2 and 0.5 days...If released to water, vinyl chloride will rapidly evaporate... [with] a half-life of 0.805 hr."Meanwhile, according to data from the Association for American Railroads, rail shipments of chemicals used in plastic production grew by about a third over the past decade. Chemicals have become a particularly important business for railways because one of their traditional mainstays, coal transportation, has fallen steeply with the decline in the mining and burning of coal. This is during a time where fears over rail safety have increased, with unions claiming more frequent disasters are likely while private rail companies continue to prioritise profit over safety. Polyvinyl chloride (PVC or vinyl) is the most toxic plastic for our health and the environment. For more than 30 years, leading health, environmental justice, and health-impacted organizations across the country and world have been campaigning to phase out this poison plastic.

The symptoms and signs associated with mild to severe acute VCM exposure-shortness of breath, cough, dizziness, headaches, respiratory depression, and CNS depression-could be due to any number of industrial toxins, particularly other volatile halogenated hydrocarbons. A history of VCM exposure will help guide diagnosis. The Ohio train derailment saw 38 cars derailed, including 11 containing hazardous materials, forcing hundreds of local residents to evacuate for several days The EPA says preliminary test results show dioxin levels in East Palestine are below the federal action thresholds, "although a few samples taken in public-rights-of-way have elevated levels of compounds". However, Schade thinks testing the food supply chain will be vital. If you have ever rolled Play-Doh in your hands, placed it in one end of a garlic-press-like gadget and squeezed it out the other, then you know how PVC compound is made. Once PVC has been synthesised from its component chemicals, the raw resin is then mixed with a variety of additives, heated to form a molten plastic compound, forced like spaghetti strands through a die and chopped into pellets.The tension between the state and its subjects plays out more dramatically on “Deer Dance,” where riot police shove their guns into the ribs of peaceful anti-capitalist protesters. “Pushing little children/With their fully automatics/They like to push the weak around,” Tankian chants at the chorus, calling to mind any number of images from the past 15 years: mass shootings at high schools or concerts, demonstrations turned violent at the hands of the cops. There’s a light, playful quality to his voice throughout the verse. He trills the “R” in the word “brutality” and swoops in and out of the melody. Then, at the chorus, Tankian snaps into a scream and Malakian grinds between two chords, squeezing all the space out of the arrangement. The verse is like watching a riot on TV, with commercials breaking up the violent footage. The chorus breaks the glass and transports you into the claustrophobic mayhem of the crowd. The Weight of the Evidence on DEHP: Exposures Are a Cause for Concern, Especially During Medical Care PVC in Schools This information should reassure people who were briefly exposed. Cancer from chemicals does not work this way; it takes a long period of exposure. I haven't seen any comparisons, but I'd bet my last penny that the cancer risk from smoking absolutely dwarfs that of a single exposure to vinyl chloride, no matter the dose.

This is where the difference between vinyl chloride and alcohol becomes apparent. Different chemicals form different combustion products. Obviously, automobile exhaust doesn't pose an acute threat or everyone on the Cross Bronx Expressway would be dead. But the same cannot be said for vinyl chloride. Its combustion products are anything but benign. A partial list:The acute toxicity (rat oral LD50 >4000 mg/kg; rat and mouse inhalation LC 50 390,000 mg/m3 and 294,000 mg/m3 respectively) is low. Anesthetic effects have been reported in humans at levels of 12,000 ppm (30,720 mg/m3 for a five-minute exposure period. The production of PVC involves combining chlorine with ethylene, which is obtained from oil, to form vinyl chloride monomer (VCM). Molecules of VCM are polymerised to form PVC resin, and additives are incorporated to give the PVC certain properties.
