Aromatic7
ISO 22155:2011 specifies a static headspace method for quantitative gas chromatographic determination of volatile aromatic and halogenated hydrocarbons and selected aliphatic ethers in soil. (iso.org)
Hydrocarbons can be classified as being aliphatic, in which the carbon moieties are arranged in a linear or branched chain, or aromatic, in which the carbon moieties are arranged in a ring. (medscape.com)
Halogenated hydrocarbons are a subgroup of aromatic hydrocarbons, in which one of the hydrogen molecules is substituted by a halogen group. (medscape.com)

Solvents2
Halogenated hydrocarbon solvents are ubiquitously distributed toxic compounds. (iso.org)
The recreational use of inhaling hydrocarbons and other volatile solvents for the purposes of creating a euphoric state is becoming increasingly common. (medscape.com)
Aliphatic1
While most aliphatic hydrocarbons have little GI absorption, aspiration frequently occurs, either initially or in a semidelayed fashion as the patient coughs or vomits, thereby resulting in pulmonary effects. (medscape.com)
Exposure3
Toxicity from hydrocarbon exposure can be thought of as different syndromes, depending on which organ system is predominately involved. (medscape.com)
Pulmonary complications, especially aspiration, are the most frequently reported adverse effect of hydrocarbon exposure. (medscape.com)
If patients are too obtunded to provide a history, hydrocarbon exposure may be suspected if their breath or clothing has an odor or if a container is found near them. (msdmanuals.com)
Ingestion4
Toxicity from hydrocarbon ingestion can affect many different organs, but the lungs are the most commonly affected. (medscape.com)
The chemical properties of the individual hydrocarbon determine the specific toxicity, while the dose and route of ingestion affect which organs are exposed to the toxicity. (medscape.com)
Hydrocarbon poisoning may result from ingestion or inhalation. (msdmanuals.com)
After ingestion of even a very small amount of liquid hydrocarbon, patients initially cough, choke, and may vomit. (msdmanuals.com)
Carbon6
If alcohol has been consumed along with a halogenated hydrocarbon, particularly carbon tetrachloride, there is rapid onset and progression of symptoms. (brainkart.com)
Skin contact with many halogenated hydrocarbons, especially carbon tetrachloride can lead to dermatitis through defatting action. (brainkart.com)
In organic chemistry , a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon . (wikipedia.org)
Unsaturated hydrocarbons , which have one or more double or triple bonds between carbon atoms. (wikipedia.org)
Hydrocarbons are a heterogeneous group of organic substances that are primarily composed of carbon and hydrogen molecules. (medscape.com)
Hydrocarbons, if ingested in large amounts, may be absorbed systemically and cause central nervous system (CNS) or hepatic toxicity, which is more likely with halogenated hydrocarbons (eg, carbon tetrachloride, trichloroethylene). (msdmanuals.com)
Derivatives1
In the fossil fuel industries, hydrocarbon refers to naturally occurring petroleum , natural gas and coal , or their hydrocarbon derivatives and purified forms. (wikipedia.org)
Compounds3
The electron capture detector is used for detecting electron-absorbing components (high electronegativity) such as halogenated compounds in the output stream of a gas chromatograph. (wikipedia.org)
An ECD has a limited[clarification needed] dynamic range and finds its greatest application in analysis of halogenated compounds. (wikipedia.org)
High sensitivity mode works well for compounds such as halogenated alkanes and substituted aromatics, as well as mixtures with one or more compound of low concentration. (vernier.com)
Headspace1
ISO 16035:2003 specifies a method for the determination of low-boiling halogenated hydrocarbons by means of static headspace gas chromatography. (iso.org)
of the characterized TOC, the most significant portions were organic acids and oxygenated/heteroatomic hydrocarbons. (epa.gov)
Organic acids and oxygenated/heteroatomic hydrocarbons comprised the bulk of the characterized TOC with halogenated hydrocarbons present in lesser but still significant quantities. (epa.gov)
The toxicity of hydrocarbons is directly related to their physical properties, specifically the viscosity, volatility, surface tension, and chemical activity of the side chains. (medscape.com)
The amount of hydrocarbon ingested has not consistently been linked to the degree of aspiration and hence pulmonary toxicity. (medscape.com)
Produces1
Note that halogenating a hydrocarbon produces something that is not a hydrocarbon. (wikipedia.org)
Hepatic1
Sevoflurane should not be used in patients with a history of confirmed hepatitis due to a halogenated inhalational anesthetic or a history of unexplained moderate to severe hepatic dysfunction with jaundice, fever and eosinophilia after anaesthesia with sevoflurane. (medicines.org.uk)
Methyl bromide, and possibly some other hydrocarbons, behave as alkylating agents and sulfhydryl enzyme inhibitors in mammalian tissues. (brainkart.com)
GROUP1
Ethrane is a brand name medication included in a group of medications called Halogenated hydrocarbons . (rxwiki.com)
Liquid1

Content1
Halogenated hydrocarbons were less, but still a significant portion of the overall organics content. (epa.gov)
Hydrocarbons with a high volatility can vaporize and displace oxygen, which can lead to a transient state of hypoxia. (medscape.com)
Certain halogenated hydrocarbons will break down or decompose when they are combined with high temperatures found in the fire environment. (wa.gov)
Linear1
: 623 The most general form of saturated hydrocarbons, (whether linear or branched species, and whether with without one or more rings) is C n H 2 n +2(1- r ) , where r is the number of rings. (wikipedia.org)
