Specific contaminants that are components of TPH, such as BTEX (benzene, toluene, ethylbenzene, and xylene), n-hexane, jet fuels, fuel oils, and mineral-based crankcase oil, have been studied by ATSDR and a number of toxicological profiles have been developed on individual constituents and petroleum products.
What is petroleum contaminants?
Several petroleum hydrocarbons like benzene, toluene, ethylbenzene, and xylene can cause cancer. … Soils contaminated by petroleum hydrocarbons can affect soil health. And it can do so at much lower concentrations compared to the effects on human health.
Where does the petroleum contamination come from?
Crude oil and natural gas are the two commonest petroleum hydrocarbon contaminants of soils. Davis discovered that treating soils with natural gas would produce characteristics comparable to those of naturally occurring “paraffin dirt.” Crude oil and natural gas appear to produce similar effects in many soils.
What is a petroleum based substance?
Petroleum (crude oil) and raw natural gas and condensates are naturally occurring substances potentially containing thousands of individual chemicals called hydrocarbons. … The primary fraction such as Gases, Naphtha, Distillate/Gas Oil, or Residuum. Other nomenclature such as Extracts, Wax, etc.
What are the main contaminants may found in crude oil?
Crude oil and some petroleum products (such as diesel fuel) can contain molecules that include nitrogen (N), sulfur (S), and oxygen (O) in their structure. These molecules, also called “heterocyclics,” are ring compounds where at least one of the compounds in the ring is not carbon; that is, they are not hydrocarbons.
Why is petroleum hydrocarbons dangerous?
Some of the TPH compounds can affect your central nervous system. … Other TPH compounds can cause effects on the blood, immune system, lungs, skin, and eyes. Animal studies have shown effects on the lungs, central nervous system, liver, and kidney from exposure to TPH compounds.
Why are petroleum products a risk to human health?
Various chemicals in petroleum products in refineries can cause cancer, birth defects or other reproductive harm. … Acetaldehyde may increase the risk of cancer. Benzene can cause leukemia. Exposure during pregnancy may affect the development of the child.
What does the word petroleum means?
Petroleum is a naturally occurring liquid found beneath the earth’s surface that can be refined into fuel. Petroleum is a fossil fuel, meaning that it has been created by the decomposition of organic matter over millions of years.
Which petroleum products are obtained from soil?
- diesel fuel.
- fuel oil.
- liquefied natural gas.
- liquefied petroleum gas.
Is toothpaste made from petroleum?
Toothpaste uses poloxamer 407, a common petroleum derivative that helps oil-based ingredients to be dissolved in water.
Is plastic made from petroleum?
Although crude oil is a source of raw material (feedstock) for making plastics, it is not the major source of feedstock for plastics production in the United States. Plastics are produced from natural gas, feedstocks derived from natural gas processing, and feedstocks derived from crude oil refining.
