The studies of Deltombe, Gail at al., ECETOC 2007 Report and Ricca et al. are reliable study reports and could be used for a Weight‐of‐Evidence approach with validity 2 (study with minor deficits and not performed according to GLP principles) to describe the performance of hydrolysis of Sodium cyanide (NaCN) or Potassium cyanide (KCN) under alkaline conditions. We concluded that according to the used literature the full test of Guideline OECD 111 study should not be performed on pH 4, 7 and 9 because of the instability of Potassium cyanide in water at pH 4 and 7 and release and high vapor pressure of HCN.

The Aerobic Metabolism of Potassium Cyanide John B. Nesbitt, Assistant Professor of Civil Engineering The Pennsylvania State University University Park, Pennsylvania H. Robert Kohl Gilbert Associates Cleveland, Ohio Elmer L. Wagner, Jr., Graduate Assistant The Pennsylvania State University University Park, Pennsylvania INTRODUCTION Inorganic cyanide wastes produced in the metal plating and metal hardening industries are said to be one of the most toxic wastes produced in industry. Small quantities of cyanide may be toxic to fish, while even smaller concentrations may interrupt the natural purification processes of a stream by killing the responsible microorganisms. Similar toxic effects have been observed on most biological sewage treatment processes. Most present day cyanide disposal methods are chemical processes which are expensive because of the required purchase of either chemicals, electric current or heat, and the necessary disposal of either sludge or toxic hydrogen cyanide gas. ...

The acute HC5 value of 15.8 ug/L value served as the point of departure for the derivation of the PNECaquatic for intermittent releases for both freshwater and saltwater species. The species sensitivity distribution (SSD) for acute aquatic toxicity developed by Hommen (2011) is similar to the SSD derived by the ECETOC Joint Assessment of Commodity Chemicals (2007). The SSD by Hommen includes more recent guideline studies on acute aquatic toxicity. The HC5 reported by Hommen for all aquatic species (15.8 ug/L) is lower than the EC50 values for the most sensitive freshwater and marine algal taxa (45 ug/L and 57 ug/L, respectively) as identified by ECETOC (2007). The chronic HC5 value of 2.0 ug/L value served as the point of departure for the derivation of the chronic PNECaquatic for both freshwater and saltwater species.

Effects of Long-term Cyanide Ingestion by Pigs | Semantic Scholar
The results showed a significant alteration in thiocyanate, creatinine and urea levels and in alanine aminotransferase activity of swine dosed with 4.0 and 6.0 mg/kg/KCN, indicating that long-term administration of KCN to swine affects several tissues and could adversely affect animal production. Animal performance and health status are adversely affected by long-term cyanide ingestion; however, the effects of cyanide ingestion by pigs have not been fully determined. The aim of the present study was to determine the effects of prolonged exposure to different doses of potassium cyanide (KCN) in growing-finishing swine. Twenty-four pigs, 45 days of age, were divided into four equal groups and treated with different doses of KCN: 0, 2.0, 4.0 or 6.0 mg per kg body weight per day for 70 consecutive days. The results showed a significant alteration in thiocyanate, creatinine and urea levels and in alanine aminotransferase activity of swine dosed with 4.0 and 6.0 mg/kg/KCN.

Mmp2 | Antibody-based exosite inhibitors of ADAMTS-5
Arbuscular mycorrhizal fungi (AMF) are necessary the different parts of fertile soils, in a position to provide many ecosystem services for crop production. string components, choice oxidase (AOX) and cytochrome oxidase (COX), get Mmp2 excited about particular mycorrhizal behavior. Because of this, a organic approach originated. On the pre-symbiotic stage (axenic circumstances), we examined phenotypic replies of spores with two AOX and COX inhibitors [respectively, salicylhydroxamic acidity (SHAM) and potassium cyanide (KCN)] and two development regulators (abscisic acidity C ABA and gibberellic acidity C Ga3). On the symbiotic stage, we examined phenotypic and transcriptomic (genes involved with respiration, transportation, and fermentation) replies in biosystem (glasshouse circumstances): we supervised the effects powered by ABA, and explored the modulations induced by SHAM and KCN under five phosphorus concentrations. KCN and SHAM inhibited spore germination while ABA and Ga3 induced ...

Reputation risk and Tylenol - Riskczar Consulting
The Riskczar Philosophy on reputation risk is that it is a second order risk. This means the risk to your reputation or brand is not something that can be directly mitigated or insured against, it is harmed when some other up stream event occurs. You cannot actually prevent reputation risk, but you can prevent the events that cause it.. Lets take a closer look at the Tylenol tampering crisis in 1982 when capsules were laced with potassium cyanide, killing seven people. The Tylenol brand was harmed and their market share dropped from 35% to 8% following the scare. Could this drop have been prevented?. Lets imagine that in 1979, Johnson & Johnson, who manufactured the product, had conducted a risk assessment, identifying reputation risk as one of many risks. Lets also assume that they had developed sophisticated models enabling them to quantify the financial loss of a catastrophic decline in market share like this. Having identified and assessed this risk, their next step would be to develop ...
Potassium cyanide inhibition of mixed bacterial populations
Many substances are known to inhibit cellular respiration. Relatively non-specific inhibitors are generally effective in proportion to the degree of penetration into the cell. However, the mechanism of action of cyanide is specific; cyanide irreversibly binds the iron group of cytochrome oxidase preventing transfer of electrons to oxygen. Hence, microbial sewage treatment processes may be severely disrupted by influx of cyanide bearing wastes. Cyanide toxicity was studied using a biological oxygen demand (BOD) system which was not oxygen limited. Lag times prior to exponential oxygen uptake were directly related to cyanide concentration. Each increase of 2.5 x 10-5 moles/1 KCN extended the lag period 10 to 15 hours. No oxygen up-take was exhibited in 300 hours at 5.0 x 10-4 moles/1 KCN with seed concentrations of 0.5 mg/1 (wet weight). However, at 2.0 mg/1 seed, cultures containing 5.0 x 10-4 KCN reached plateau oxygen demand in 145 hours, indicating the importance of KCN-seed ratio on degree of ...

FBI investigates Unabomber in 82 Tylenol deaths - KMOV.com
CHICAGO (AP) -- The FBI says its investigating whether Unabomber Ted Kaczynski was involved in the 1982 Chicago-area Tylenol poisonings case that killed seven people.. Kaczynski wrote in court papers filed in federal court in California last week that prison officials conveyed a request from the FBI in Chicago for DNA samples.. Chicago FBI spokeswoman Cynthia Yates confirmed Thursday that the agency has asked for Kaczynskis DNA. She says hes refused to voluntarily give a sample but declined to say whether the agency could compel him to provide one.. The Tylenol case involved the use of potassium cyanide and resulted in a mass recall. Kaczynski says he has never possessed potassium cyanide.. Kaczynski is serving a life sentence after pleading guilty in 1998 to setting 16 explosions that killed three people.. (Copyright 2011 by The Associated Press. All Rights Reserved.). ...

Several unstable mutant hemoglobins have alterations which affect areas of the molecule involved in the attachment of heme to globin. Loss of heme from globin has been demonstrated during the denaturation of some of these unstable mutants. The importance of heme ligands for the stability of hemoglobin was illustrated in the present experiments on the denaturation of several hemoglobins and hemoglobin derivatives by heat, oxidative dyes, and alkali. Heating of normal hemolysates diluted to 4 g of hemoglobin per 100 ml at 50°C for 20 hr in 0.05 M sodium phosphate, pH 7.4, caused precipitation of 23-54% of the hemoglobin. Dialysis against water or dilution of the sample decreased denaturation to 12-20%. Precipitation was decreased to less than 3.5% by the presence of 0.015 M potassium cyanide. Increasing the ionic strength of the medium increased precipitation. Cyanide prevented the formation of inclusion bodies when red cells containing unstable hemoglobin Philly, β35 tyr → phe, were incubated ...

How the Tylenol murders of 1982 changed the way we consume medication | PBS NewsHour
Early on the morning of Sept. 29, 1982, a tragic, medical mystery began with a sore throat and a runny nose. It was then that Mary Kellerman, a 12-year-old girl from Elk Grove Village, a suburb of Chicago, told her mother and father about her symptoms. They gave her one extra-strength Tylenol capsule that, unbeknownst to them, was laced with the highly poisonous potassium cyanide. Mary was dead by 7 a.m. Within a week, her death would panic the entire nation. And only months later, it changed the way we purchase and consume over-the-counter medications.

Glutaric acid - Wikipedia
Glutaric acid can be prepared by the ring-opening of butyrolactone with potassium cyanide to give the mixed potassium carboxylate-nitrile that is hydrolyzed to the diacid.[1] Alternatively hydrolysis, followed by oxidation of dihydropyran gives glutaric acid. It can also be prepared from reacting 1,3-dibromopropane with sodium or potassium cyanide to obtain the dinitrile, followed by hydrolysis. ...
Cyanide - New World Encyclopedia
Cyanide is any chemical compound containing a cyano group (C≡N), which consists of a carbon atom triple-bonded to a nitrogen atom. Specifically, cyanide is the anion CN-. The various cyanides are salts or esters of HCN (hydrogen cyanide or hydrocyanic acid), whereby the hydrogen is replaced with a metal or radical, yielding such as potassium cyanide (KCN), calcium cyanide (CA(CN)2), or ethyl cyanide (CH3CH2CN). Organic compounds that feature cyanide as a functional group (responsible for the characteristic chemical reactions of those molecules) are called nitriles in IUPAC nomenclature. For example, CH3CN is referred to by the names acetonitrile or ethanenitrile per IUPAC, but occasionally it is labeled using the common name methyl cyanide. Of the many kinds of cyanide compounds, some are gases, while others are solids or liquids. Those that can release the cyanide ion CN- are highly toxic. For plants, cyanide offers an effective chemical defense against herbivores. Remarkably, it occurs ...
CYNIDE TOXICITY
Cyanide most commonly occurs as hydrogen cyanide and its salts-sodium and potassium cyanide. Cyanides are both man-made and naturally occurring substances. They are found in several plant species as cyanogenic glycosides and are produced by certain bacteria, fungi, and algae. In very small amounts, cyanide is a necessary requirement in the human diet. Cyanides are released to the environment from industrial sources and car emissions (ATSDR, 1989).. Cyanides are readily absorbed by the inhalation, oral, and dermal routes of exposure. The central nervous system (CNS) is the primary target organ for cyanide toxicity. Neurotoxicity has been observed in humans and animals following ingestion and inhalation of cyanides. Cardiac and respiratory effects, possibly CNS-mediated, have also been reported. Short-term exposure to high concentrations produces almost immediate collapse, respiratory arrest, and death (Hartung, 1982; EPA, 1985). Symptoms resulting from occupational exposure to lower ...
Plasmid-mediated rifampicin resistance in Pseudomonas fluorescens | Microbiology Society
SUMMARY
Rifampicin is an antibiotic mostly used to treat tuberculosis and leprosy, and, occasionally, other diseases. Resistance is due to alterations in membrane permeability or to mutation in the rpoB gene coding for mRNA polymerase. Both these mechanisms originate via chromosomal mutation. However, a rifampicin-resistant Pseudomonas fluorescens strain harboured a multiresistance plasmid which transferred rifampicin resistance when transformed into P. putida or Escherichia coli. Rifampicin readily diffused into the sensitive cells of the E. coli and P. putida recipients, but the transformants with the plasmid, pSCL were resistant to the drug and did not accumulate it. Potassium cyanide restored the diffusion of rifampicin into the resistant cells, indicating that an efflux pump was involved in the resistance mechanism. The resistance of the transformants and the wild strain was also abolished in sphaeroplasts generated by EDTA lysozyme treatment. Analysis of membrane proteins by SDS-PAGE revealed the

A comparative study was conducted in rat primary cortical (CX) and mesencephalic (MC) neurons to investigate intracellular cascades activated during cyanide-induced injury and to determine the point at which the cascades diverge to produce either apoptosis or necrosis. Cyanide treatment (400 μM) for 24 h produced primarily apoptosis in CX cells, whereas the same concentration of cyanide induced predominantly necrosis in MC cells as indicated by increased propidium iodide staining and cellular lactate dehydrogenase efflux. Cyanide increased generation of cellular reactive oxygen species (ROS) in both CX and MC cells, but the rate of formation and nature of the oxidative species varied with cell type. Catalase decreased cyanide-induced ROS generation in CX but not in MC cells. Nitric oxide generation was more prominent after cyanide treatment of MC compared with CX cells.N-Methyl-d-aspartate receptors were more involved in CX apoptosis than in MC necrosis. Mitochondrial membrane potential ...
Cyanide Effects on Plants | eHow
Even given all of these direct and indirect effects of cyanide exposure to plants, it is highly unlikely for humans to be exposed to large enough amounts of cyanide to be put at risk; still, its important to know the signs of cyanide exposure just to err on the side of caution. The earliest effects of cyanide exposure are rapid, deep breathing and shortness of breath followed by convulsions (seizures) and loss of consciousness. Prolonged exposure to small amounts of cyanide over long periods of time has been linked to breathing difficulties, chest pain, vomiting, blood changes, headaches and enlargement of the thyroid gland. Exposure to large amounts of cyanide in a short time can cause brain and heart damage and in some cases can lead to coma and death.. ...
