- Polycyclic Aromatic Hydrocarbons (PAHs). Polycyclic aromatic hydrocarbons (PAHs) are a class of chemicals that occur naturally in coal, crude oil, and gasoline. They also are produced when coal, oil, gas, wood, garbage, and tobacco are burned.PAHs generated from these sources can bind to or form small particles in the air.High-temperature cooking will form PAHs in meat and in other foods.hey also are produced when coal, oil, gas, wood, garbage, and tobacco are burned.

- The introduction of petroleum hydrocarbons (or other degradable organics) may cause a perturbation to the existing geochemistry, resulting in the mobilization of arsenic at concentrations above the ambient level. Petroleum and other degradable organics lower the redox state to more reduced conditions.rsenic is naturally found in many soils. It may be present as specific minerals or it may be present as an adsorbed phase on metal (primarily iron) oxyhydroxides and other clay minerals. There are over 500 naturally occurring arsenic minerals.

Petroleum naphtha Petroleum naphtha is an intermediate hydrocarbon liquid stream derived from the refining of crude oil.here are hundreds of different petroleum crude oil sources worldwide and each crude oil has its own unique composition or assay. There are also hundreds of petroleum refineries worldwide and each of them is designed to process either a specific crude oil or specific types of crude oils.

Petroleum Composition Although the composition of petroleum will contain many trace elements the key compounds are carbon (93% – 97%), hydrogen (10% - 14%), nitrogen (0.1% - 2%), oxygen (01.% - 1.5%) and sulphur (0.5% - 6%) with a few trace metals making up a very small percentage of the petroleum composition.he composition of petroleum is defined as laid out above, and it is this composition which gives the crude oil its properties. Raw petroleum is usually dark brown or almost black although some fields deliver a greenish or sometimes yellow petroleum.

Toxic Substances Portal - Polycyclic Aromatic Hydrocarbons (PAHs) This fact sheet answers the most frequently asked health questions about polycyclic aromatic hydrocarbons (PAHs). For more information, you may call the ATSDR Information Center at 1-800-232-4636. This fact sheet is one in a series of summaries about hazardous substances and their health effects. PAHs can break down by reacting with sunlight and other chemicals in the air, over a period of days to weeks. 2  PAHs enter water through discharges from industrial and wastewater treatment plants. 3  Most PAHs do not dissolve easily in water. 4  They stick to solid particles and settle to the bottoms of lakes or rivers.

The Classification of Petroleum In general, if the crude oil contains high levels of sulphur the petroleum classification is termed ‘sour, if it has relatively low levels of sulphur the petroleum classification is termed ‘sweet'.he hydrocarbons in crude oil can generally be divided into four categories: 1  Paraffins: These can make up 15 to 60% of crude and have a carbon to hydrogen ratio of 1:2, which means they contain twice the amount of hydrogen as they do carbon.

Breathing air contaminated with motor vehicle exhaust, cigarette smoke, wood smoke, or fumes from asphalt roads are common ways exposure occurs. People take in PAHs when they eat grilled or charred meats or foods or foods on which PAH particles have settled from the air.

Petroleum in the United States Petroleum in the United States. Petroleum in the United States has been a major industry since shortly after the oil discovery in the Oil Creek area of Titusville, Pennsylvania in 1859. The petroleum industry includes exploration for, production, processing (refining), transportation, and marketing of natural gas and petroleum products. As of 2008, the U.S. was the world's third-largest oil producer (after Saudi Arabia and Russia), producing 8.5 million barrels of oil and natural gas liquids per day.

Petroleum jelly The raw material for petroleum jelly was discovered in 1859 in Titusville, Pennsylvania, United States, on some of the country's first oil rigs.etroleum jelly, petrolatum, white petrolatum, soft paraffin or multi-hydrocarbon, CAS number 8009-03-8, is a semi-solid mixture of hydrocarbons (with carbon numbers mainly higher than 25), originally promoted as a topical ointment for its healing properties.

- A US Navy review of properties along the Elizabeth River in Virginia examined 20 sediments, and concluded that urban background was 16 mg/kg for a 16-PAH list of priority pollutants and 26 mg/kg for all detectable PAHs.oal tar, crude oil, and shale oil are all important repositories of PAHs, and human conversion and incomplete combustion of fuels increases their abundance in the contemporary environment (NPI, 2004). Products such as creosote and asphalt also contribute to PAH occurrence in the environment (IDPH, 2005).

Natural Breakdown of Petroleum Results in Arsenic Mobilization in Groundwater The freezing drive shoe enables nearly complete core recovery from saturated, sandy aquifers. Photo credit: Jeanne Jaeschke, Changes in geochemistry from the natural breakdown of petroleum hydrocarbons in groundwater promote mobilization of naturally occurring arsenic from aquifer sediments into groundwater.esults from this field investigation reveal that arsenic concentrations in the hydrocarbon plume can reach 230 micrograms per liter (µg/L), or 23 times the current drinking water standard of 10 µg/L.

Polycyclic aromatic hydrocarbon Polycyclic aromatic hydrocarbons are hydrocarbons—organic compounds containing only carbon and hydrogen—that are composed of multiple aromatic rings. Formally, the class is further defined as lacking further branching substituents on these ring structures. The simplest such chemicals are naphthalene, having two aromatic rings, and the three-ring compounds anthracene and phenanthrene. PAHs are non-charged, non-polar molecules found in coal and in tar deposits. They are also produced by ...

10 childrenâs snacks made with petroleum products! 10 children’s snacks made with petroleum products! Monday, January 04, 2016 by Greg White. One of the best gifts parents can bestow upon their children is a healthy diet. This treasured gift, however, has been tarnished in an age of fast food and mono-agriculture. Many of the products stored on supermarket shelves nowadays are laced with toxic ingredients, like petroleum — and you could be inadvertently purchasing them. Rather than images of food, petroleum conjures images of oil and gas in most people’s minds — and rightly so. Although petroleum can help fuel your car, it most definitely won’t help fuel your health. To ensure the vitality of your family, be sure to avoid these petroleum-laced food marketed towards children: 1. Kraft’s Macaroni and Cheese

Chemicals in Meat Cooked at High Temperatures and Cancer Risk Studies have shown that exposure to HCAs and PAHs can cause cancer in animal models (6). In many experiments, rodents fed a diet supplemented with HCAs developed tumors of the breast, colon, liver, skin, lung, prostate, and other organs (7 – 12).
