Poisoning intentional

We will probably never know whether Napoleon died from arsenic poisoning, intentional or accidental, but this exercise in historical sleuthing provides a fascinating example of the use of chemical analysis. Not only is chemical analysis used in forensic science, but it also plays an essential part of endeavors ranging from pure research to practical applications, such as quality control of commercial products and medical diagnosis. 

Hall and Hassell (50) continued these studies with the intention of proving that possible traces of oxide dissolved in the metal play no significant role in the poisoning or promoting effects arising from hydrogen which had been presorbed during the pretreatment procedure. The catalysts were prepared in essentially the same manner as before. The kinetics... 

Emetics are used to cause vomiting to empty the stomach rapidly when an individual has accidentally or intentionally ingested a poison or drug overdose Not all poison ingestions or drug overdoses are treated with emetics. 

In case of accidental or intentional poisoning, contact the nearest poison control center before using or giving this drug. Not all poisoning can be treated with this drug. 

Symptoms of endosulfan poisoning have been seen in some people who were exposed to very large amounts of this pesticide during its manufacture. Symptoms of endosulfan poisoning have also been seen in people who intentionally or accidentally ate or drank large amounts of endosulfan. Most of these people experienced convulsions or other nervous system effects. 

Similarly, convulsive seizures and a sustained epileptic state persisted after stomach contents were pumped and activated charcoal and anticonvulsive medication were administered in a 43-year-old man who ingested approximately 260 mg/kg endosulfan (Boereboom et al. 1998). At 4 days after exposure, the man was pronounced brain dead, and autopsy revealed cerebral hernia from massive cerebral edema. Eight additional accidental and/or intentional cases of acute poisoning with endosulfan resulting in adverse neurological effects have been reported in more recent studies, six by Blanco-Coronado et al. (1992), one by Lo et al. (1995), and one by Pradhan et al. (1997) two out of the eight resulted in death. Tonic-clonic convulsions were seen in the Blanco-Coronado et al. (1992) cases, whereas Lo et al. (1995) reported the development of muscle fasciculations and episodes of convulsions in their case. In the case reported by Pradhan et al. (1997), the patient had consumed about 75 mL of hquid endosulfan (35% w/v). In this case, in addition to tonic-clonic seizures and myoclonic jerks, the patient developed... 

Information is available regarding excretion of endosulfan and metabolites in humans. Blanco-Coronado et al. (1992) measured total endosulfan in the urine of poisoned individuals shortly after poisoning occurred. However, it could not be ascertained whether the urine was a major or minor excretion route. a-Endosulfan, P-endosulfan, and/or metabolites were present in the urine of humans after intentional oral exposure (Boerebomm et al. 1998) and after occupational exposure either with (Arrebola et al. 1999) or without (Vidal et al. 1998) protective clothing. 

One promising extension of this approach Is surface modification by additives and their Influence on reaction kinetics. Catalyst activity and stability under process conditions can be dramatically affected by Impurities In the feed streams ( ). Impurities (promoters) are often added to the feed Intentionally In order to selectively enhance a particular reaction channel (.9) as well as to Increase the catalyst s resistance to poisons. The selectivity and/or poison tolerance of a catalyst can often times be Improved by alloying with other metals (8,10). Although the effects of Impurities or of alloying are well recognized In catalyst formulation and utilization, little Is known about the fundamental mechanisms by which these surface modifications alter catalytic chemistry. 

Reverse The logical opposite of the intention This is mostly applicable to activities, for example reverse flow or chemical reaction. It can also be applied to substances, e.g. Poison instead of Antidote or D instead of L optical isomers... 

Accidental or intentional ingestion of folk remedies containing lead (discussed in Section 5.5) represents another source for potential lead-poisoning in children. Acute lead encephalopathy in early infancy has been reported in a Middle Eastern study for 14 infants following the use of Bint al Thahab, a traditional...

An average fatal dose of 1.52 mg/kg cyanide for humans has been calculated from case report studies of intentional or accidental poisonings (EPA 1987a). The lowest fatal oral dose reported in humans is 0.56 mg/kg cyanide (Gettler and Baine 1938). 

At high doses dioxin causes a serious form of acne (chloracne), which appears to be Yuschenko s problem. If the poisoner s intention was to kill him, then he failed to select the right chemical. There are many far more effective acute poisons, as we shall see in the next chapter. 

No studies were located regarding death in humans after oral exposure to heptachlor or heptachlor epoxide. However, since heptachlor is a major component of the insecticide chlordane, chlordane poisoning can be considered when evaluating heptachlor toxicity data. In the case study of a woman who ingested 6 g of chlordane with suicidal intent and died 9.5 days following ingestion, no information was presented on the composition of the chlordane. Therefore, the amount of heptachlor exposure is unknown, and the effect of other components of chlordane cannot be ruled out (Derbes et al. 1955). 

Strychnine poisoning occurs from accidental and intentional ingestion and from misuse as a therapeutic agent. Doses of 5-7 mg cause muscle tighmess, especially in the neck and jaws, and twitching of individual muscles, especially in the little fingers. ... 

Exposure to toxicants can vary, producing what is known as acute or chronic poisoning. Poisoning can also be classified according to the intent of use. Poisoning can either be suicidal (non-accidental) or accidental in nature. Recreational poisoning, such as substance abuse, can be a source of harmful intoxication and, in some cases, can lead to addiction and withdrawal symptoms. Intentional harm is observed when there is criminal doping with sedative-hypnotic medicines, often associated with robberies.
